Servicing Appliances in Adelaide’s Older Inner Suburbs

by Marsh | Jun 8, 2026 | Coffee Machine Repair

If you have spent any time in Unley, Norwood, Prospect, Goodwood, or Fitzroy, you know the type of kitchen we're talking about. High ceilings. Pressed metal details. A laundry that was tacked on sometime in the 1970s to a house that was built in the 1890s. A kitchen that got modernised once, maybe twice. But you can still see the original stone or brick bones through whatever got plastered over them.

These are some of the most characterful homes in South Australia. They are also, from an appliance servicing perspective, some of the most interesting to work in. Not because they are difficult exactly. But because the combination of old bones and modern equipment creates situations that do not come up in a ten-year-old double-brick suburban house.

We at National Appliance Repairs service appliances right across Adelaide, and our technicians are well-acquainted with the inner suburbs. Here is a practical guide to what owners and renters in older Adelaide homes should know about keeping appliances running well.

The Housing Stock: What You're Working With

Adelaide's inner suburbs have some of the densest collections of pre-Federation and Federation-era housing in the whole country. Here is what you tend to find:

• Stone cottages and villas: Built from the 1840s through to the 1890s. Bluestone or limestone rubble walls. You see them everywhere in Norwood, Fitzroy, Unley, Hyde Park, and parts of Prospect: Small footprints. Low ceilings in the original sections. Usually got a later addition tacked on the back. Laundries were either outbuildings or enclosed lean-tos. Good luck fitting a modern washing machine in some of them.
• Victorian and Federation homes: Roughly 1890s to 1915. Larger. Often double-fronted. More decorative detailing--bullnose verandahs, return verandahs, decorative iron lace. The kitchen and laundry areas were usually added in later decades. Often replacing whatever was at the back originally. That is where things get interesting.
• Edwardian and Bungalow styles: 1910s to 1930s. More common in Prospect, Kensington Park, Fullarton, and Goodwood. Wider blocks than the earlier terraces. More of the original rear areas survive intact. But they have still been through decades of additions and modifications.

The thing about these homes is that they typically have undergone several renovations. The result is rarely a nice, coherent upgrade. It is a layering of different decades' solutions. Each layer solved a problem for the people at the time. And each layer created constraints for whoever came next. That next person is often us, trying to figure out where to put a new dishwasher.

The Kitchen: Space and Power Constraints

Limited bench space and awkward appliance niches

Inner suburb Adelaide kitchens were not designed for 90cm freestanding ovens or large double-door fridges. Original kitchen footprints in stone cottages can be remarkably small -- 3 to 4 square metres before any appliances are placed.

When an oven or cooktop is replaced in these homes, the new appliance often needs to match the existing cavity dimensions very closely. A 60cm oven is the standard, but the surrounding joinery or stone walls may limit depth, and there's rarely room to widen the opening without a significant renovation.

Before replacing any built-in appliance in an older Adelaide kitchen, measure the cavity depth, width, and height precisely -- and include the connections. In stone-walled homes, the wall behind the oven cavity is often original stone: you can't easily shift it, and ovens that run deeper than the existing space won't fit.

Electrical circuits

Older Adelaide homes were often extended piece by piece, with each renovation tacking on new circuits that worked at the time. Very few homeowners would think about the overall switchboard capacity. Take an inner suburb stone cottage that got a kitchen in the 1980s. There might be one circuit running the oven, the rangehood, and every power point on that wall.

Since a modern oven draws more current than an old one, the underpowered circuit would trip over and over. A nuisance aside, it would put undue stress on your oven. You need a licensed electrician to upgrade the breaker or add a dedicated circuit.

Under the Electrical Safety Act 1998 (SA), all prescribed electrical work in South Australia must be performed by a licensed electrician, and a Certificate of Compliance is required for any new circuit installation.

The Laundry: Adelaide's Rear-Addition Problem

The laundry in most older Adelaide inner-suburb homes was retrofitted. The original house had no indoor laundry -- washing was done in a copper out the back. When indoor laundries became standard, they were typically added as lean-tos or incorporated into rear renovations, with the space available determining the result.

In practice this means:

• Narrow, awkward spaces where standard appliance widths barely fit
• Plumbing connections in unexpected locations, often not centred on the available wall space
• Low ceiling heights in lean-to additions that preclude stacking a dryer on top of the washing machine
• Concrete or unlevel tile floors in older lean-to additions that make washing machine levelling difficult
• Drainage at floor level rather than through the wall, which affects which machines connect cleanly

When a washing machine or dryer in one of these spaces needs replacing, measure not just the machine dimensions but the doorway into the laundry -- standard 60cm washing machines have come through 620mm openings, but that's cutting it close, particularly if the door frame has been through repairs and is no longer perfectly square.

Hard Water and Appliance Longevity in Adelaide

Any appliance that uses water in Adelaide's inner suburbs is fighting the same hard water problem as the rest of the metro area -- and in some cases worse, because the older the pipes, the more accumulated scale can be introduced into the water supply within the home itself.

For dishwashers, simply keep the salt reservoir filled, set the hardness level correctly, and descale every three to four months.

For washing machines, Adelaide's mineral-rich water contributes to faster-than-average limescale build-up in the drum, the pump, and the internal hoses. Running a hot descale cycle every two to three months slows this considerably. In homes with particularly hard water, a plumber-installed inline filter can reduce the mineral load reaching the machine.

Access for Appliance Technicians in Older Homes

Most inner suburb Adelaide homes don't have the access complications of a multi-storey apartment tower, but they can have their own quirks:

• Narrow side passages between homes are common in terrace-style properties and older cottages on small blocks. A technician bringing replacement parts or removing a large appliance may need to negotiate a 700mm passage.
• Original stone or brick steps at rear entries can complicate appliance movement. A slight lip that's charming architecturally becomes a real problem when you're trying to wheel out a top-loader on a trolley.
• Laundries accessible only through the kitchen require clearing a clear path through what is often the most cluttered room in these older homes.

None of these are significant obstacles -- they're just worth knowing about. When you call to book a repair, mentioning that access requires navigating a narrow side passage or that the laundry is only accessible through the kitchen lets the technician plan appropriately and bring the right equipment.

Common Faults We See in Older Adelaide Homes

FAQ

My oven keeps tripping the circuit breaker in my old Adelaide cottage -- is it the oven or the wiring?

Both are possible. A single trip on first use of a new oven often indicates an older circuit that isn't sized for the new appliance's draw. An electrician can assess the circuit. Repeated tripping with an established oven suggests either a fault in the oven (a shorted element is common) or a deteriorating circuit connection -- again, the electrician should look first, then the appliance technician if the circuit checks out.

Can a standard washing machine be installed in a lean-to laundry with a concrete floor?

Yes, though concrete can be uneven in older lean-tos, and proper levelling of the machine's feet is particularly important on a hard floor -- unlevel machines vibrate excessively and develop drum bearing problems faster. Adjustable anti-vibration feet or a rubber mat under the machine also help.

Do older Adelaide homes have specific compliance requirements for new appliance installations?

New circuit work requires a licensed electrician and a Certificate of Compliance under SA legislation regardless of the age of the home. For gas appliances, work must be done by a licensed gasfitter under the Gas Act 1997 (SA). The age of the home doesn't change these requirements.

My stone cottage has very thick walls -- does this affect appliance installation or venting?

It can affect dryer venting in particular. Running a vent duct through a 400mm stone wall is possible but requires core drilling and appropriate flashing. For homes where external venting is difficult, a condenser or heat pump dryer (which doesn't require an external vent) is often a more practical choice.

I've bought a character home in Prospect/Norwood/Unley and want to upgrade the kitchen appliances. Where do I start?

Start with measurements -- actual cavity dimensions, not the previous appliance's stated dimensions. Measure depth as well as width and height, and check what's behind the existing appliances (stone, brick, or timber frame determines what modification is possible). Have an electrician assess the kitchen circuits before buying a new oven, especially if you're upgrading from a smaller model to a 90cm unit. Then call us to discuss options.

Conclusion

Adelaide's older inner suburbs are full of homes that reward thoughtful ownership. The appliances in them need the same care -- matched to the specific constraints of the space, maintained for hard water conditions, and serviced by technicians who know what to expect.

We at National Appliance Repairs service all major appliance brands across Adelaide's inner suburbs and beyond. If you're dealing with a fault in a Norwood cottage, a Prospect bungalow, or a Unley villa, call 1300 434 380 and we'll work around whatever the home presents.

What Temperature Should a Freezer Be?

by Marsh | Jun 8, 2026 | Coffee Machine Repair

Most people set the freezer once and assume it's working as long as the ice cream stays solid. But there's a difference between "frozen" and "frozen correctly" -- and if your freezer is running at -10°C instead of the recommended -18°C, your food is technically frozen but losing quality, developing freezer burn faster, and not being stored safely for the shelf lives most guides recommend.

Getting the freezer temperature right is one of those small adjustments with a genuinely large impact on food quality, energy use, and how long the appliance itself lasts. At National Appliance Repairs, we service chest freezers, upright freezers, and fridge-freezer combinations across Australia. The right temperature is straightforward -- here's what you need to know.

The Recommended Freezer Temperature in Australia

Your freezer should sit at -18°C or colder. That's the standard from CHOICE Australia, and it matches what food authorities use worldwide.

At -18°C, a few things happen. Bacteria stop multiplying (they're not killed at freezer temps, just put on pause). Enzyme activity that breaks down quality slows way down. Food keeps its nutrition, texture, and flavour for as long as the recommended storage periods say it should.

Healthdirect Australia says -15°C is the bare minimum for food safety, but -18°C is where you want to be for the best results.

Why -18°C, Not Just "Whatever Freezes Things"

Food begins freezing at 0°C, but the process continues down to much colder temperatures. Ice cream, for example, only fully freezes at around -15°C -- which is why ice cream can feel soft and scoopable even in a freezer that's technically operating, if that freezer is only reaching -10°C or -12°C.

At -10°C:

• Many frozen foods are solid but not fully frozen
• Enzymatic reactions continue at a low but meaningful rate, degrading quality faster
• Freezer burn (surface dehydration and oxidation) develops more quickly
• Recommended frozen storage times are significantly shorter

At -18°C:

• Water in food is essentially fully frozen throughout
• Quality degradation is very slow
• Recommended storage times (3 months for most cooked meals, 6--12 months for raw meat depending on type) are achievable

Running a freezer warmer than -18°C doesn't make the food unsafe immediately, but it does mean the food deteriorates faster and the storage guidelines on packaging no longer apply.

How to Check Your Freezer Temperature

Most domestic freezer controls use a numbered dial or slider rather than a direct temperature display. To find the actual temperature, you need a freezer thermometer -- they cost a few dollars at any kitchenware or hardware retailer.

Place the thermometer inside the freezer and check it after the freezer has been closed for at least eight hours. The reading should be -18°C or colder. If it's above -15°C, adjust the thermostat to a colder setting, wait another eight hours, and check again.

For combination fridge-freezers, adjusting the freezer temperature setting can sometimes affect the fridge section, depending on how the cooling system is configured. Check both compartments after any adjustment.

Freezer Temperature by Food Type

These timelines assume the food is stored at a consistent -18°C in appropriate packaging. Food stored at warmer temperatures will deteriorate faster.

Common Reasons a Freezer Isn't Cold Enough

If your thermometer confirms the freezer is running warm, work through these in order:

• Start with the thermostat. Dial it toward colder and wait a few hours to see if it helps.
• Check the door or lid seal. On uprights, a worn gasket is a common culprit -- warm air sneaks in. On chest freezers, close the lid and look for gaps.
• Look for frost build-up. Manual-defrost models can get caked with frost on the inside walls. This frost acts as insulation, so cold can't reach the food even though the compressor is running overtime. Defrost it regularly and you'll fix this.
• If you have a frost-free model, don't overpacking it. Stuff it too full and you block airflow to the evaporator fan, which causes uneven freezing and warm spots.
• Consider the location. A freezer in a Brisbane garage during summer is basically cooking from the outside in. The compressor can't keep up with that heat load.
• If you've checked all that and the freezer's still warm, you likely have a compressor or refrigerant problem -- a leak, a failing compressor, or a faulty thermostat. Call a technician at this point.

Freezer Burn: What It Is and How to Prevent It

Freezer burn is the greyish-white, dry, papery patches that appear on frozen food -- particularly meat, poultry, and ice cream -- after extended storage. It's caused by moisture migrating from the food to the cold air in the freezer and depositing as ice crystals on the food's surface, leaving the food dehydrated and oxidised.

Freezer-burned food is safe to eat but significantly degraded in texture and flavour. Prevention:

• Store food in airtight, freezer-rated packaging or sealed freezer bags with as much air removed as possible
• Don't leave partially used bags loosely closed in the freezer
• Maintain a consistent -18°C -- warmer temperatures and temperature fluctuations accelerate freezer burn
• Use food within the recommended storage times

Defrosting Your Freezer

Manual-defrost freezers accumulate frost over time and need periodic defrosting to maintain efficiency. The general guide is to defrost when frost build-up reaches about 6mm thickness.

A heavily frosted freezer:

• Runs its compressor more frequently and for longer, using more electricity
• Has reduced usable internal space
• Maintains temperature less effectively -- internal temperature rises as frost accumulates

For frost-free freezers, automatic defrost cycles run periodically without requiring manual intervention. If a frost-free freezer is developing heavy frost, the defrost heater, defrost thermostat, or defrost timer may have a fault.

FAQ

What is the minimum safe temperature for a freezer in Australia?

Healthdirect Australia advises -15°C as the minimum for frozen food safety. -18°C is the recommended target for optimal quality. Running a freezer between -15°C and -18°C is technically above the recommended target but not immediately unsafe -- food will simply deteriorate faster than the storage guides assume.

My freezer dial goes from 1-5. What number should I use?

Higher numbers mean colder temps, but your dial doesn't show actual temperatures. Set it to the highest (coldest) setting, then measure with a thermometer after 8 hours. If it reads below -22°C, dial back slightly. You're aiming for -18°C.

Can food that thawed during a power outage be refrozen?

Only if it still has ice crystals throughout, or you've confirmed the temperature stayed at 0°C or below. If it's fully thawed, cook it right away or throw it out. Refreezing thawed food that's been in the danger zone risks food poisoning.

Why does my ice cream stay soft even though the freezer seems to be running?

Ice cream gets noticeably soft above -15°C. If yours is consistently soft and easy to scoop, the freezer's probably running between -10°C and -14°C. Use a thermometer to check, look at your thermostat setting, and inspect the door seal. A compressor struggling in a hot garage during summer can also cause this.

Does it cost more to run the freezer colder?

Slightly -- each degree colder uses a bit more energy. But a clean, properly sealed freezer at -18°C usually costs less overall than a poorly maintained one at -12°C. The neglected freezer has to run its compressor more often to make up for dirty coils, frost buildup, or a bad door seal.

Conclusion

-18°C is the target and it's worth confirming with a thermometer at least once a year. Most freezer temperature problems have a simple cause -- a thermostat setting, a frost build-up, or a worn door seal -- and are straightforward to resolve.

If a freezer is consistently failing to reach or hold -18°C despite correct settings and a clean seal, the compressor or refrigerant system may need attention.

How to Use Dishwasher Salt and Rinse Aid

by Marsh | Jun 8, 2026 | Coffee Machine Repair

Two compartments in your dishwasher rarely get the attention they deserve: the salt reservoir and the rinse aid dispenser. Most households fill them on purchase -- or never fill them at all -- and leave the settings at whatever the delivery person configured. But using both correctly, with the right settings for your water hardness and usage, makes a genuine difference to how clean your dishes come out and how long the machine lasts.

This article covers the practical steps for both. For a deeper explanation of what dishwasher salt is and why it matters, see our article on what dishwasher salt is and whether you need it.

At National Appliance Repairs, our technicians regularly see the effects of salt and rinse aid misuse on dishwasher internals. Hard water scale on heating elements, blocked spray arm holes, and persistent cloudy glassware are almost all preventable with the right maintenance habits.

Part 1: Dishwasher Salt

What you'll need

• Dishwasher salt (available at any Australian supermarket in the cleaning products aisle)
• The funnel that came with your dishwasher (usually stored inside the machine)
• A cloth or paper towel
• Your dishwasher's manual (to confirm the location of the reservoir and any hardness settings)

Locating the salt reservoir

Remove the lower rack from the dishwasher. The salt reservoir is a round compartment in the floor of the machine, usually towards the front left or centre, with a screw-top cap -- often marked with an "S" icon or the word "salt". In some machines the indicator light on the control panel will tell you when the reservoir is low; in others you need to check manually.

Filling the reservoir

• Unscrew the cap counterclockwise and set it aside. Note that the reservoir is filled with water -- this is normal. The water is how the salt creates the brine solution used during regeneration.
• Place the funnel (included with most machines) into the opening. If you've lost the funnel, a small plastic kitchen funnel works. A steady hand and slow pouring also works for experienced users.Pour in the salt. Fill until you can see salt just below the top of the opening -- don't overfill. Most reservoirs hold approximately 1 to 1.5 kg. Some water will overflow as salt displaces it; this is normal.
• Wipe the threads around the reservoir opening before replacing the cap. Any salt sitting on the threads will corrode them over time, making the cap progressively harder to remove.
• Screw the cap back on firmly -- but do not overtighten it. It only needs to be hand-tight.
• Run a short cycle immediately before loading any dishes. Salt that has spilled into the machine's base can leave a salty residue on dishes in the next wash. A short rinse cycle flushes this away.

Setting the water hardness level

Most dishwashers with a built-in softener let you dial in your local water hardness, which tells the machine how often to run a regeneration cycle. Too low and the softener can't keep up -- scale forms. Too high and you're just burning through salt.

You'll find the setting either on a dial inside the salt reservoir compartment or somewhere in the digital menu. Check your manual if you're not sure where.

To set it right, you need your water hardness in milligrams per litre (mg/L) or degrees of hardness (°dH). Your water authority publishes this:

• SA Water for Adelaide
• Water Corporation for Perth
• Sydney Water for Sydney
• Melbourne Water for Melbourne
• Seqwater for south-east Queensland

Once you have the hardness figure, match it to the scale in your machine's manual and set accordingly. Most Adelaide and Perth households will need a mid-to-high hardness setting. Sydney and Melbourne households are typically at the lower end.

Water hardness reference guide for dishwasher settings:

How often to top up

In most Australian households using the dishwasher daily:

• Soft water areas (Melbourne, Sydney): every two to three months
• Moderate hard water (Adelaide metro, Perth metro): monthly or close to it
• Hard water areas (some regional WA, regional QLD): potentially fortnightly

The indicator light, if your machine has one, is the most reliable guide. If the machine has no indicator, check the reservoir monthly as a starting habit and adjust frequency based on how quickly it empties.

Part 2: Rinse Aid

What rinse aid does

Rinse aid is a surfactant -- it reduces the surface tension of water, causing it to sheet off dishes and glassware in thin, even films rather than forming water droplets. Droplets dry and leave mineral spots; sheeting water evaporates cleanly. In hard water areas, where every drop of water carries dissolved minerals, this difference in drying behaviour has a large effect on the final appearance of glassware and cutlery.

Rinse aid also speeds up the drying cycle by promoting faster water runoff, reducing drying time and energy use.

Locating the rinse aid dispenser

The rinse aid dispenser is built into the inside of the dishwasher door, usually next to the detergent compartment. It has a small circular or rectangular cap, often marked with a wave or sun icon. Many machines have a small window in the cap that allows you to see the rinse aid level without opening it.

Filling the dispenser

• Open the dispenser cap -- it usually lifts or twists open rather than unscrewing.
• Pour rinse aid slowly into the opening. Most dispensers hold around 150--200ml. Fill until the level indicator (if present) shows full, or until rinse aid just reaches the base of the opening -- do not overfill.
• If any rinse aid spills onto the door or into the machine, wipe it up immediately. Spillage can cause excessive foaming during the next wash cycle.
• Close the cap firmly.

Setting the dosing level

The rinse aid dispenser has an adjustable dosing dial -- typically numbered 1 to 6, with higher numbers delivering more rinse aid per cycle. The correct setting depends on your water hardness:

• Soft water: setting 2--3
• Moderately hard water (most of Adelaide, Perth): setting 4--5
• Hard water: setting 5--6

If you see spots or cloudiness on glassware after washing, increase the dosing setting by one step and test over a few cycles. If you see rainbow streaks or a sticky film on dishes (over-dosing), reduce the setting by one step.

How often to refill

With daily dishwasher use and a mid-range dosing setting, the rinse aid dispenser typically needs refilling every four to eight weeks. The indicator window on the cap changes colour when the level is low; many machines also have an indicator light on the control panel.

Using Salt and Rinse Aid Together

Salt and rinse aid aren't interchangeable -- they do completely different things.

• Salt works at the start, softening the water before it hits the wash cycle. That reduces mineral load across the whole wash and protects the machine's internal components.
• Rinse aid works at the end, helping water sheet off dishes during the final rinse so they dry without spots.

In moderate-to-hard water, you need both. One without the other means either scale damage or spotty glasses.

Common Mistakes to Avoid

• Never put dishwasher salt in the detergent compartment. Salt is highly concentrated and can corrode the stainless steel interior if it sits directly in the wash water without being diluted through the softener system.
• Never use table salt as a substitute. Fine grain size, added iodine, and anti-caking agents make it unsuitable and potentially damaging to the softener resin.
• Never put rinse aid in the salt reservoir. They go in separate compartments for good reason.
• Don't skip the post-fill rinse cycle. Always run a short cycle after filling the salt reservoir to flush any spilled salt from the machine.
• Check both indicators monthly rather than waiting for problems to appear on your dishes.

FAQ

The salt indicator light is on even though I just filled the reservoir -- why?

The sensor measures brine concentration, not whether salt is present. After filling, the salt needs time to dissolve and build up a strong enough brine solution for the sensor to register. Run a cycle or two and the light should go off.

Do I need rinse aid if I use all-in-one tablets?

In soft water, the rinse aid in the tablet is usually enough. In moderately hard water -- which covers most of Adelaide, Perth, and parts of other capitals -- it often isn't, and you'll see spots and film on glassware. Fill the dispenser and set it to a lower dose.

My dishwasher manual asks for a hardness setting but I don't know my water hardness -- where do I find it?

Your local water authority publishes annual water quality reports online. Search "[your city] water hardness" or go directly to your supplier's website. SA Water, Sydney Water, Melbourne Water, Water Corporation (Perth), and Seqwater (South-East Queensland) all publish this data.

Can I leave the salt reservoir empty if I have a whole-house water softener?

If your softener is delivering genuinely soft water to all taps, the dishwasher may not need salt at all. Set the hardness to the lowest level and confirm with a water hardness test kit at the tap.

How long does a bag of dishwasher salt last?

A 2 kg bag at mid-level hardness with daily use lasts roughly two to four weeks in a hard water area like Adelaide, or two to three months somewhere with softer water. In hard water areas, buying in bulk makes more sense.

Conclusion

Using dishwasher salt and rinse aid correctly is a small investment of time and attention that pays back in cleaner dishes, better-looking glassware, and a longer-lasting dishwasher. Set the hardness level once based on your local water supply, develop a habit of checking the indicators monthly, and the rest takes care of itself.

Why Adelaide’s Water Is Brutal on Dishwashers and How to Protect Yours

by Marsh | Jun 7, 2026 | Coffee Machine Repair

Ask any Adelaide plumber or appliance technician what their most reliable repeat business is, and dishwasher descaling and hard water damage will come up fast. Adelaide's water has a reputation, and while the city has improved its treatment significantly over the decades, the mineral content remains higher than most other Australian capitals -- and dishwashers take the brunt of it.

Water hardness is a measure of dissolved calcium and magnesium content, expressed in milligrams per litre (mg/L) of calcium carbonate equivalent. Sydney draws from soft, granite-filtered catchments with hardness typically below 50 mg/L. Melbourne sits similarly low. Adelaide is a different story.

At National Appliance Repairs, our Adelaide technicians service dishwashers across the metro area every week. Hard water damage is visible in a predictable pattern -- it's entirely manageable once you understand what's happening and why.

Adelaide's Water Hardness: The Numbers

According to WaterScore, Adelaide has the hardest metropolitan water of any major capital in Australia. Depending on where you live, hardness can run anywhere from 87 to 136 mg/L. Some of the northern and western suburbs--Salisbury, Port Adelaide, West Lakes--regularly see levels above 110 to 120 mg/L. Eastern suburbs like Burnside, Norwood, and Unley are generally lower, but they are still well above what Sydney or Melbourne deal with.

Now, SA Water has its own definitions. They class water above 200 mg/L as "hard" and anything between 60 and 200 mg/L as "good quality." That sounds reassuring, until you look at what dishwasher manufacturers actually recommend. Bosch, Miele, most of the major brands say that once water hardness goes above 70 mg/L, you should be using dishwasher salt to soften it inside the machine.

At Adelaide's typical levels? Most of the metropolitan area is above that threshold, and not by a little.

What Hard Water Does to a Dishwasher

When hard water heats up inside a dishwasher -- and the wash cycle typically reaches 55-75°C -- the dissolved calcium and magnesium precipitate out of solution and deposit as limescale on every surface the water touches. This includes:

• Spray arms: The small holes in the spray arms are the first casualty. Limescale accumulates inside the holes and on the outer rim, reducing water flow and altering the spray pattern. The dishes in certain rack positions stop getting properly cleaned -- usually the far corners that depend on a specific spray arm hole being unblocked.
• Heating element: The element at the base of the dishwasher reaches the highest temperature in the machine. Scale builds fastest here, forming an insulating layer that forces the element to work harder to heat the water to the target temperature. Over time, this shortens element life and increases energy consumption. Heavy scale on a heating element is one of the most common causes of dishwasher faults in Adelaide homes.
• Interior walls and door: White or grey streaking on the stainless steel interior is mineral scale. It doesn't affect function directly, but it's a useful indicator of how aggressively the water is depositing minerals throughout the machine.
• Glassware and dishes: The cloudiness that develops on glasses after repeated dishwasher cycles in Adelaide is mineral film -- calcium and magnesium deposits left behind when water evaporates from the glass surface. It's cosmetically unpleasant and resists normal detergent washing once it builds up.
• Water inlet valve and internal pipes: Scale accumulation in narrow passages restricts water flow over time, contributing to pressure issues, fill problems, and eventually complete blockages in older machines.

The Dishwasher Salt Question

Most European dishwashers -- and the majority of mid-to-high-end dishwashers sold in Australia are European-designed -- have a built-in water softener in the base of the machine. It works by passing the incoming water through an ion exchange resin that swaps calcium and magnesium ions for sodium ions, producing softer water for the wash cycle.

The resin is regenerated automatically using dishwasher salt (specifically formulated coarse salt, not table salt). When the salt reservoir is empty, the softener stops working and hard water flows through the machine unchecked.

In Adelaide, keeping the salt reservoir filled is not optional maintenance -- it's the primary defence against scale damage. How often you refill it depends on your water hardness level and how frequently you run the machine, but in most metro Adelaide households using the dishwasher daily, checking and refilling monthly is a reasonable habit.

Set the water hardness level correctly Most dishwashers with a built-in softener have a hardness setting that determines how aggressively the softener operates. It is usually set using a dial or through the machine's digital menu. Check your manual and set it to match your local water hardness -- for most Adelaide metro addresses, a setting equivalent to around 100 mg/L (or the equivalent in your machine's units) is appropriate. An incorrectly low setting means the softener undershoots and scale still forms. An unnecessarily high setting wastes salt.

Rinse Aid: The Second Line of Defence

Rinse aid reduces the surface tension of water, causing it to sheet off dishes and glassware rather than forming droplets that dry into mineral spots. In hard water conditions, rinse aid is particularly effective at reducing the cloudiness and spotting that Adelaide water leaves on glasses.

Make sure the rinse aid reservoir is regularly topped up, and check that the dosing setting is appropriate for your water hardness -- most dispensers have an adjustable dial from 1 to 6. For Adelaide water, a mid-to-high setting typically gives the best result.

Descaling: When to Do It and How

Even with salt and rinse aid in use, scale builds up over time, particularly on the heating element and spray arms. Descaling the machine every three to six months is advisable in Adelaide.

How to descale:

• Run an empty hot cycle with a commercial dishwasher descaling tablet or with 250ml of white vinegar placed in a dishwasher-safe cup on the top rack (do not mix the two -- run one or the other)
• Remove and soak the spray arms in white vinegar for 20 minutes, then clear any blocked holes with a toothpick, before the descaling cycle if possible
• After descaling, run one plain rinse cycle before using the machine for dishes

If the machine has been running without salt for an extended period, a single descaling cycle may not be enough to remove heavy built-up scale. Successive cycles over a few weeks will progressively break it down.

Suburb-by-Suburb: Adelaide's Hardness Variation

Note: These ranges are indicative based on SA Water data. Local hardness can vary with seasonal changes to the water source. SA Water publishes annual water quality reports that include hardness data by zone.

FAQ

Do I need dishwasher salt if I use all-in-one dishwasher tablets?

All-in-one tablets include a small amount of salt and rinse aid components, but not in quantities sufficient for Adelaide's water hardness levels in machines with a dedicated softener. If your machine has a salt reservoir, fill it with dishwasher salt regardless of which tablets you use -- the integrated softener needs it to function properly.

My dishwasher is producing cloudy glasses even with rinse aid -- is this the water or the machine?

Cloudiness from mineral deposits is Adelaide's most common dishwasher complaint. Check whether salt is present and the hardness setting is correctly configured. Run a descaling cycle. If cloudiness persists after these steps, the spray arm holes may be partially blocked, reducing rinsing effectiveness -- clean them with a toothpick and a vinegar soak.

How long does a dishwasher last in Adelaide vs. soft water cities?

If you skip the salt and descaling, your dishwasher will likely die early as heating elements go and spray arms becoming clogged in just 6 to 8 years – perhaps even sooner. With good maintenance, a dishwasher can typically hit 10 to 15 years.

Can a whole-house water softener help?

Yes, especially if it’s installed by a professional plumber. A water softener can strip out minerals from the water before it hits the dishwasher.

My old dishwasher is not doing well, should I repair or replace it in Adelaide?

Before you replace it, get a tech to clean the spray arms, descale it, and check the heating element. A lot of "dying" dishwashers in Adelaide are just neglected and not broken.

Conclusion

Adelaide's water is not going to get dramatically softer. Dishwashers in this city will always be working harder than they would in Melbourne or Sydney. The response is straightforward maintenance. Keep the salt reservoir filled. Set the hardness level correctly. Use rinse aid. Descale every few months. Those four habits make a significant difference to how long a dishwasher lasts and how well it performs.

When a fault goes beyond maintenance -- a heating element that has failed, a control board issue, a spray arm that is cracked rather than just blocked -- we at National Appliance Repairs service dishwashers across Adelaide. Call 1300 434 380 for a fast diagnosis and honest repair assessment.

What Temperature Should a Fridge Be?

by Marsh | Jun 7, 2026 | Coffee Machine Repair

It's one of those settings most people set once and never revisit. The dial gets turned to the middle, the fridge gets cold enough that the milk stays fresh, and that's considered job done. But if you've ever had food go off faster than it should, or noticed ice forming on your salad at the back of the shelf, the fridge temperature is usually the first thing worth checking.

The right fridge temperature isn't just about keeping food cold. It's about keeping food safe, reducing waste, and running the appliance efficiently. At National Appliance Repairs, our technicians see the effects of incorrect fridge temperatures regularly -- both in food safety complaints and in faults that develop when a compressor is pushed harder than necessary. Here's what you actually need to know.

The Recommended Temperature Range

For a domestic fridge in Australia, the correct temperature range for the fresh food compartment is 0°C to 4°C. The ideal target is 3°C. That is what the Australian Standard recommends.

CHOICE Australia agrees. They say 3°C is the practical target to aim for. It is cold enough to sit comfortably below the 4°C upper safe limit. But it also leaves enough buffer so that normal fluctuations--opening the door, adding warm food--do not push the fridge into freezing territory.

Now, Food Standards Australia New Zealand sets 5°C as the maximum safe temperature for perishable food. At or below 5°C, bacterial growth slows down to a rate that keeps food safe for its expected shelf life. Above 5°C, bacteria multiply quickly. That raises the risk of food-borne illness.

The 3°C target straddles the line between food safety and freezing point, with headroom on both ends -- making it the most practical temperature to set your fridge to.

The Temperature Danger Zone

In Australia, the temperature danger zone for food safety is 5°C to 60°C. Bacteria like Salmonella, Listeria, and E. coli thrive in that range. Some of them can double in number every 20 minutes under the right conditions.

Now, the rule from FSANZ is simple.

• Food that has been in the danger zone for more than four hours? Bin it.
• Food that has been in there between two and four hours? Use it immediately. Do not put it back in the fridge.
• Under two hours? You can refrigerate it or use it.

This is called the 2-hour/4-hour rule.

For your home fridge, the practical implication is clear. If your fridge is running above 5°C, every single item inside is at elevated risk. Every hour it sits there. So keeping that temperature right is not just about energy bills or appliance longevity. It is about not getting sick.

What About the Different Zones in Your Fridge?

Temperature is not uniform throughout a fridge. Most fridge interiors have warmer and colder zones, and understanding them helps you store food correctly.

Coldest areas:

• The bottom shelf and the area directly in front of the back panel (where cold air enters)
• The chiller drawer, if your fridge has one -- this sits close to 0°C and is designed for meat, fish, and poultry

Warmer areas:

• The door shelves, which are exposed to room temperature every time the fridge opens
• The top shelf, which tends to be warmer than lower shelves in most fridge designs

Storage guide based on zones:

• Bottom shelf / chiller drawer: Raw meat, poultry, seafood (coldest zone; keeps these items safest and prevents drip contamination onto other foods)
• Middle shelves: Dairy, eggs, leftovers, cooked food
• Top shelf: Drinks, foods less sensitive to temperature variation
• Crisper drawers: Fruit and vegetables (slightly higher humidity helps extend freshness)
• Door shelves: Condiments, juices, butter -- items with longer shelf lives and lower food safety risk

How to Check Your Fridge Temperature

Your fridge dial actually controls cooling intensity, not temperature – so the number “1” or “2” doesn’t necessarily mean 1 or 2°C. A thermometer is the only tool that'll actually tell you what's inside.

Place one in a glass of water on the middle shelf and leave it overnight. The next day, check the reading. You're looking for 4°C or below.

Higher than that? Your fridge needs to run colder. Too cold? You'll spot ice crystals on foods that should stay unfrozen.

The reason this matters: fridges run warmer than most people realize. A NSW Food Authority study found that nearly one in four Australian home fridges averaged above 5°C -- which is a food safety issue.

Fridge Temperature Quick Reference

Common Reasons a Fridge Isn't Reaching the Right Temperature

If your fridge is consistently running warmer than it should, a few common causes are worth checking before calling a technician:

• The thermostat dial is set too warm. Check the setting and adjust as described above.
• The door seal is damaged or not sealing properly. A faulty seal allows warm room air to enter continuously. Close a piece of paper in the door -- if it slides out with no resistance, the seal needs replacing.
• The fridge is overpacked. Cold air needs to circulate to maintain an even temperature. A fridge so full that air can't move will have warm spots.
• The fridge is placed in a hot environment. A fridge in a hot garage or in direct sun works harder to maintain temperature and may struggle in Australian summer conditions.
• The condenser coils are dirty. Dusty coils at the back or base of the fridge can't dissipate heat effectively, causing the compressor to overwork and the interior to run warm.
• The fridge is too empty. A nearly empty fridge loses temperature quickly when the door opens and takes longer to recover. Keeping a few containers of water in the fridge adds thermal mass.

If the fridge is still running warm after checking these, the problem may be a failing thermostat, a compressor issue, or low refrigerant -- all of which need a qualified technician.

Does Fridge Temperature Change by Season?

It can. Especially in Australia. Think about summer. Your fridge is in a hot kitchen or a hot garage. The ambient temperature around it rises. The compressor has to work harder just to keep up. And the internal temperature can drift upward without you even noticing.

So try this simple habit: At the start of every summer, check your fridge temperature with a thermometer. Adjust the thermostat if you need to. That one habit reduces food spoilage and saves energy.

FAQ

What is the maximum safe fridge temperature in Australia?

5°C, according to Food Standards Australia New Zealand (FSANZ). Above that, bacteria multiply fast. But in practice, you'll want to aim for 3°C for a safe buffer.

Why is my fridge set to 3 but still not cold enough?

It's likely because the number on the dial doesn't mean Celsius. A 3 on one fridge is not the same as a 3 on another. In this case, you'll want to trust a refrigerator thermometer, instead to check the actual temperature. We do not recommend you trust the dial.

Is it bad to keep the fridge too cold?

Yes. Below 0°C and you freeze things that should not freeze like veggies, dairy, and anything liquid. It'll also cause ice build-up that blocks airflow. Stick to 0–4°C.

Where should eggs go? Door or shelf?

Middle shelf while it's still in the carton. The door is the warmest part and fluctuates most. Carton on a shelf keeps eggs stable and stops them absorbing other food smells.

Dial goes 1 to 7. What setting do I use?

Higher number = colder usually. But the only real answer is to measure it. Start at the midpoint. Check the actual temperature after 8 hours and adjust from there. Aim for 3°C.

Conclusion

The right fridge temperature -- 0°C to 4°C, with 3°C as the practical target -- is not set-and-forget. It's worth checking with an appliance thermometer at least once a year, and again after any major environmental change (a move, a hot summer, a fridge in a new location). Most of the food safety and spoilage problems that seem like a fridge fault are actually a temperature calibration issue.

If your fridge is struggling to reach or maintain safe temperatures despite correct settings and a good door seal, there may be a mechanical fault involved.

Why Appliance Parts Take Longer in Perth and How to Avoid the Wait

by Marsh | Jun 6, 2026 | Coffee Machine Repair

Perth is, by most measures, the most geographically isolated major city in the world. The nearest large city is Adelaide -- more than 2,100 kilometres away by road. Sydney is around 3,900 kilometres away by road. That's not a gap you bridge overnight, and for anything shipped along the ground, it means freight times that the rest of Australia simply doesn't experience.

For appliance parts, this has real consequences. When a washing machine control board or a dishwasher pump needs to come from an east coast distribution centre -- which is where most appliance parts warehouses in Australia are located -- Perth customers are at the end of a long logistics chain. Understanding why the wait happens, and what can be done to shorten it, is practical knowledge for anyone managing appliance repairs in Western Australia.

At National Appliance Repairs, we service appliances across Perth and manage parts sourcing for repairs every day. The geographic reality shapes how we operate, and we think it's worth being transparent about it.

The Geography Problem

Most major appliance brands -- Bosch, Fisher & Paykel, Electrolux, Samsung, LG, Miele -- run their Australian parts distribution out of warehouses in Sydney, Melbourne, or both. When a technician in Brisbane or Melbourne needs a spare part, it's often a same-day or next-day order. When the same order goes to Perth, air freight is the fast option; road freight is the default.

Road freight from Sydney or Melbourne to Perth typically takes four to seven business days for standard consignments. Add in any warehouse processing time, and a part that would arrive within 24 hours in Sydney can take a week or more to reach a Perth address.

Air freight is faster -- one to two business days in most cases -- but it's significantly more expensive and is generally reserved for urgent orders or high-priority commercial accounts. For standard residential repairs, parts typically travel by road.

The result is a repair timeline that looks quite different from what customers in other capital cities experience. A fault that could be resolved in one or two days on the east coast may require a week to ten days in Perth purely due to transit time -- even when the diagnosis is clear and the part is in stock.

When Parts Aren't Stocked Locally

The secondary issue is local inventory. Parts distributors balance the cost of holding stock against demand. For a high-volume part -- a common washing machine pump, a standard oven element -- local Perth distributors are likely to carry stock. For less common parts, or for newer model-specific components, the order goes east.

Older or discontinued appliance models can be particularly difficult. If a manufacturer's part is no longer actively distributed in Australia, it may need to come from an international warehouse or be sourced through a specialist. That adds further time.

Appliance brands with strong local distribution networks in Perth -- and Fisher & Paykel, which manufactures in New Zealand and has well-established Australian distribution, is a notable example -- generally have better parts availability in WA than brands that distribute entirely from east coast hubs.

What Affects the Wait (and What Doesn't)

The factors that genuinely shorten the wait are local stock and air freight. Everything else -- the fault type, the brand, the model age -- affects which category the part falls into.

How to Avoid the Longest Waits

Use a technician who carries common parts

The most effective way to avoid a wait is to work with a technician whose service van carries stock of the most commonly needed parts. For high-volume repairs -- pump replacements, door seal replacements, standard heating elements -- a well-stocked technician can complete the repair on the first visit. Ask when booking whether common parts for your appliance brand and type are typically carried on the van.

Describe the fault accurately when booking

The more precisely the fault is described, the better the chance a technician can identify the likely part needed and bring it to the first visit. "Won't drain" is more useful than "not working." "Makes a grinding noise on spin" is more useful than "has a problem." Accurate fault descriptions let an experienced technician make a reasonable parts prediction before they arrive.

Avoid peak storm and holiday periods for non-urgent repairs

Parts warehouses, like all logistics operations, experience slower turnaround around public holidays and during periods of high volume. In Perth, delays compound further because each additional day of processing time in an east coast warehouse becomes proportionally more significant when combined with a multi-day freight leg.

Confirm parts availability before committing to a repair

For older appliances where the age and model might make parts harder to source, it's worth asking your technician to confirm parts availability before proceeding. Discovering that a part has a three-week wait after the repair has been started is a poor outcome for everyone. A good technician will check availability upfront and discuss options if the timeline is problematic.

Consider the repair vs replace calculation realistically

For appliances that are eight to ten or more years old, a parts delay is also a useful moment to assess whether repair is the right call. If the part costs $250, freight adds $50, and the appliance is twelve years old with an expected remaining life of two to four years, the economics of a like-for-like replacement may be worth running. We'll always be honest with you about that assessment rather than push a repair that doesn't make sense.

What We Do to Minimise the Wait in Perth

When we take a booking for an appliance repair in Perth, our approach is:

• Diagnose thoroughly on the first visit -- understanding the exact fault means ordering the right part the first time, avoiding secondary delays from incorrect orders
• Carry high-turnover Perth parts stock on our vans -- for the most common repair types we see in Perth, parts travel with the technician
• Use air freight for urgent repairs -- for appliances where the delay causes genuine hardship (a primary fridge, a washing machine in a household with young children), we can escalate the freight priority
• Source locally where possible -- Perth has local parts distributors for many common brands, and we use them

FAQ

Why is my appliance repair taking longer in Perth than a friend in Sydney experienced?

Almost certainly a parts transit issue. Most appliance parts warehouses are on the east coast. What takes one to two days to reach Sydney from a Melbourne warehouse takes five to seven days by road freight to Perth. It's not the fault of the technician or the repair company -- it's the geography.

Can I speed up the repair by paying for express freight?

Yes, in most cases. Air freight from Sydney or Melbourne to Perth takes one to two business days rather than five to seven. There will be a freight cost associated with this, which we'll confirm before proceeding. For urgent situations, it's usually a worthwhile expense.

What if the part for my appliance is no longer made?

Discontinued parts can sometimes be sourced through specialist suppliers in Australia or internationally, or reconditioned parts may be available. In some cases, a comparable alternative part can be used. Your technician should advise on availability and any implications of using a non-original part.

Does the brand of appliance affect how quickly parts arrive in Perth?

Yes. Brands with strong Australian distribution networks -- including those with Perth-based distributors -- have better local availability. Brands that distribute exclusively from east coast hubs will always face the freight delay. Fisher & Paykel, for example, has well-established Australian distribution that often serves Perth faster than some imported European brands.

Is it worth buying a local brand to make future repairs easier in Perth?

Parts availability and servicing support are worth factoring into any appliance purchase in WA, especially for premium or specialist brands. If local servicing support and parts turnaround matter to you, ask the retailer about the brand's local distribution before buying.

Conclusion

Parts delays in Perth are a function of geography, not inefficiency. The distance is real, and freight timelines reflect it. The most effective mitigation is working with a technician who carries common parts, describes the fault precisely, and plans the repair with the freight reality in mind.
