Your appliance has broken. A technician gives you a repair quote. Now you face the decision: fix it or buy new?
This isn't always an obvious choice. A $300 repair on a 6-year-old appliance makes sense. A $400 repair on a 12-year-old appliance does not. The decision depends on multiple factors: age, repair cost, replacement cost, energy efficiency, and expected lifespan. The team atNational Appliance Repairs helps customers make this decision every week, and we've developed a framework that removes guesswork. This guide walks you through that same decision-making process with examples and real numbers so you can make the right call for your situation.
The 30% Rule: A Starting Point
Here's a quick rule that applies to most appliances:
If the repair costs less than 30% of a new appliance's price, repair usually makes sense.
If the repair costs more than 50% of replacement, replacement usually makes sense.
The zone between 30-50% is where you need to think more carefully.
Example: Your refrigerator's compressor has failed. Repair cost is $450. A new refrigerator costs $1,500.
$450 / $1,500 = 30%. You're right at the boundary. Either decision is defensible. You need other factors to push you one way or another.
Example: Your washing machine needs a new motor. Cost is $400. A new washing machine costs $1,000.
$400 / $1,000 = 40%. You're in the thinking zone. Age and other factors matter.
Example: Your dishwasher needs a new pump. Cost is $250. A new dishwasher costs $900.
$250 / $900 = 28%. Repair is clearly the better choice unless other factors are at play.
This rule is a starting point, not a final answer. Use it to frame your thinking.
Additional Factors That Influence the Decision
Age of the appliance. This is the single biggest factor after repair cost.
Appliances under 5 years old: Repair almost always makes sense. The appliance has significant lifespan remaining. An investment in repair extends the useful life.
Appliances 5-8 years old: Repair makes sense if the repair cost is reasonable. The appliance has several more years ahead.
Appliances 8-10 years old: You're in the decision zone. Repair might extend life 2-3 more years. Is that worth it? Consider how much longer you want to keep this appliance.
Appliances over 10 years old: Replacement often makes sense. You've gotten good life from it. A new, efficient appliance will serve you better long-term. However, if the repair is cheap (under $200) and the appliance still works otherwise, repair is defensible.
Expected remaining lifespan. Ask the technician: "How much longer would I realistically get from this appliance if I repair it?"
If they say "probably another 5-7 years," that pushes you toward repair.
If they say "this repair extends life 1-2 years, but you'll probably face other issues soon," that pushes you toward replacement.
Reliability history. Has this appliance been reliable, or has it had multiple repairs?
One major repair in an appliance's lifetime is normal. A repair at year 4 or 5 is nothing unusual.
Multiple repairs in the past 18 months are a red flag. You're pouring money into a declining appliance. Replacement might be smarter.
Energy efficiency. Older appliances use more electricity than new models.
A new refrigerator uses 20-30% less energy than a 10-year-old model. Over 10 years, that savings can offset the replacement cost.
A new washing machine uses significantly less water and electricity than older models.
For appliances you use frequently (refrigerators, washing machines, dishwashers), energy savings can be substantial.
Calculate the potential savings. Australia's electricity rate is approximately 27 cents per kWh. If a new appliance uses 30% less energy and your current appliance costs $100/year to run, the new one saves roughly $30/year. Over 10 years, that's $300 in savings. This doesn't cover replacement cost, but it factors into the decision.
Your budget. Can you afford replacement right now?
If the repair is $300 and you can afford it, repair solves the immediate problem. You don't have to budget for a replacement for several more years.
If replacement costs $1,500 and you're not in a position to spend that now, repair buys you time. You can plan for replacement in 1-2 years when finances allow.
Emotional attachment or preference. This is valid.
If you love your appliance and it's served you well, repair makes sense.
If you've been wanting to upgrade to a different style or brand, replacement is the opportunity.
The Break-Even Analysis for Major Appliances
For appliances you use frequently, calculate whether replacement makes financial sense over time.
Example: Washing Machine
Current washing machine: 10 years old, costs $150/year to run (electricity and water). Repair needed: $350 (motor replacement). New washing machine: Costs $900, uses 30% less energy/water, estimated yearly cost $100.
If you repair: Spend $350 now. Run the old machine for another 2-3 years at $150/year = $300-450 total cost.
If you replace: Spend $900 now. Run new machine for 10 years at $100/year = $1,900 total cost over 10 years.
Over the 2-3 year period, repair is cheaper. Over a 10-year period, replacement might be comparable or slightly cheaper when you factor in energy savings and no additional repairs.
This analysis helps you see the long-term financial impact of your decision.

Frequently Asked Questions
Is it ever worth replacing an appliance that still works?
Yes, if energy savings or functionality improvements justify the cost. An ancient refrigerator using 40% more electricity than a new model might cost you $300+ annually in wasted energy. Replacement might pay for itself in 5 years through savings alone. But if the appliance still works fine, there's nothing wrong with keeping it.
What if I can't afford replacement right now?
Repair buys you time. A $300-400 repair extends life 2-3 years. You can plan for replacement when finances allow. This is perfectly reasonable.
Should I always repair, or should I always replace?
Neither. It depends on the specific situation. Use the framework: age, repair cost, replacement cost, reliability history, energy efficiency, and budget. These factors together determine the best decision.
If repair cost is 40% of replacement, what should I do?
You're in the decision zone. Look at age and reliability history. If the appliance is under 7 years old and has been reliable, repair makes sense. If it's over 10 years old or has had multiple repairs, replacement might be smarter.

Your LG dishwasher just stopped mid-cycle and displayed an error code. Now what?
Here's what 15+ years of LG dishwasher repairs across Australia has taught us: error codes are your appliance's way of being specific about problems. Understanding what the code means is half the battle to fixing it.
We can often diagnose your exact problem over the phone just by knowing the error code and a few details about when it appeared. This guide walks through the most common LG dishwasher errors and what we actually find when we diagnose them.

IE Error: Water Inlet Fault
What it means: The machine attempted to fill with water but either the water didn't arrive or the inlet system detected a problem.
What we find when we diagnose it:
The inlet valve is stuck open or closed. LG inlet valves are electronically controlled. They can stick due to mineral buildup (especially in hard-water regions like Adelaide) or electrical failure.
Your water supply is actually shut off or restricted. Sounds obvious, but we get calls where the water valve behind the dishwasher has been accidentally turned off. Check this first.
The inlet hose is kinked, crushed, or blocked. We regularly find inlet hoses compressed against the wall or twisted during installation.
The water pressure is too low. This is rare in Australian homes, but if you have very low water pressure, the machine might not fill fast enough and triggers the IE code.
How to troubleshoot IE yourself:
Check your water supply. Look behind the dishwasher at the shut-off valve (usually a small knob or lever). Ensure it's fully open (horizontal position).
Check the inlet hose. Follow it from the water connection to where it enters the dishwasher. Look for kinks or crushing. Straighten if needed.
Run the water at your sink. Ensure normal water pressure. If it's weak, the problem might be upstream (not the dishwasher).
Look inside the dishwasher. Is water accumulating slowly instead of not at all? This suggests a slow fill rather than a complete failure. Run a short cycle and see if the error recurs.
If cleaning and straightening don't work, the inlet valve likely needs replacement. This is a professional repair.

In hard-water regions: Adelaide and parts of Brisbane see more IE errors due to mineral deposits blocking the inlet valve. We recommend:
Running a descaling cycle monthly
Having the inlet valve professionally cleaned or replaced every 5-7 years as preventative maintenance
OE Error: Drainage Fault
What it means: Water that should have drained is still present in the tub. The machine's drainage system isn't working.
What we find when we diagnose it:
(This is our most common LG error, accounting for roughly 40% of all LG service calls.)
The pump filter is clogged. Food debris, lint, hair, or mineral deposits are blocking water flow into the pump. We find filters so blocked that water can barely move through them.
The drain hose is kinked or blocked. The hose behind your dishwasher can be twisted, crushed, or internally blocked by food or mineral deposits.
Your garbage disposal is clogged. If the dishwasher drains through the disposal, a full or blocked disposal prevents drainage.
The knockout plug in the garbage disposal wasn't removed. This small rubber disc blocks the port completely. We've had to drive across Sydney to remove a knockout plug that cost a customer stress and worry.
Your home's drain system is backed up. Sometimes it's not the dishwasher at all -- your sink is clogged or your home's plumbing has a backup.
How to troubleshoot OE yourself:
Stop immediately. Unplug the machine and drain the water manually using the emergency drain hose (bottom-left of the machine, usually).
Clean the filter. Access the service panel, locate the cylindrical filter at the bottom of the tub, turn it counterclockwise, and pull it out. Rinse thoroughly under warm water. This alone fixes 60% of OE errors.
Check the drain hose. Trace it from the machine to where it enters your plumbing. Straighten any kinks you find.
Check the garbage disposal. If your dishwasher drains through it, run the disposal for 10 seconds to ensure it's clear. Look inside the disposal drain opening and check for a knockout plug (small rubber disc). Remove it if present.
Run a spin-only cycle. If water drains, the error is solved. If it persists, the problem is either internal (pump failure) or upstream (your home's plumbing).
If these steps don't work, the pump might be failing or your home's drain is backed up. Call a professional or plumber.

Australian regional note: Coastal areas see more OE errors due to increased humidity accelerating lint and debris accumulation. Clean your filter monthly if you live near the coast.
FE/AE Error: Overflow or Leak Detection
What it means: The machine's leak sensor detected water where it shouldn't be. Either there's an actual leak, or the sensor has malfunctioned.
What we find when we diagnose it:
An actual leak in the door seal. The rubber gasket is degraded, cracked, or warped, allowing water to escape. More common in humid climates (Sydney, Perth, Brisbane).
The machine isn't level. If it tilts forward or is perfectly level instead of slightly back, water pools where the sensor sits even without a leak.
A malfunctioning sensor. The float switch is corroded, damaged, or electrically faulty. It triggers even though there's no actual leak.
A loose inlet connection. Water is spraying where it shouldn't, reaching the sensor.
Your home's humidity is creating condensation that reaches the sensor. In tropical climates (Brisbane especially), high humidity can cause false triggers.
How to troubleshoot FE/AE yourself:
Look for actual water. Open the service panel and inspect the area under the tub. Is it wet or dry? If dry, there's likely no leak.
Check the door seal. Open the door and inspect the rubber gasket all around. Look for cracks, warping, or compressed areas. Clean it with warm soapy water.
Verify the machine is level. Use a spirit level on top of the dishwasher. It should be very slightly tilted back (maybe 2-3 degrees). If it's level or tilted forward, adjust the front feet by turning the bolts underneath.
Run a short test cycle. If the error doesn't recur, you've likely fixed it. If it reappears, the sensor probably needs replacement.
If water is visible or the error persists, professional service is needed.

tE Error: Temperature Sensor Fault
What it means: The machine's temperature sensor (which monitors water temperature during wash cycles) has malfunctioned or detected an impossible reading.
What we find when we diagnose it:
The sensor itself has failed. Electronic sensors can degrade over time, especially in high-humidity environments.
The sensor's electrical connection is loose or corroded. This is more common in coastal homes (Sydney, Perth) where salt air accelerates corrosion.
A genuine electrical fault in the control board's sensor circuit.
Can you fix tE yourself?
Rarely. The temperature sensor is an electronic component. If it fails, it needs replacement. This requires:
Locating the sensor (varies by model)
Disconnecting the electrical connector carefully
Installing the new sensor
Testing to ensure it works
This is professional territory. DIY attempts can damage the control board.

Cost: Sensor replacement typically runs $150-250 for the part plus labor.
bE Error: Motor or Pump Drive Error
What it means: The machine's motor or pump has encountered an electrical fault or mechanical failure. The control board has detected something wrong with the drive system.
What we find when we diagnose it:
The pump motor has failed. After years of continuous operation, the motor brushes wear, windings burn, or the motor simply stops responding to electrical signals.
The pump impeller is stuck or damaged. The spinning component inside the pump is seized or broken.
An electrical connection to the motor is loose or corroded.
A genuine control board failure affecting how it signals the motor.
Can you fix bE yourself?
No. This is a mechanical and electrical problem requiring professional diagnosis. You could damage the motor or control board attempting DIY repairs.

Cost: Motor replacement typically runs $300-500 depending on your model.
Error Code Patterns We See Across Australia
In coastal regions (Sydney, Perth):
More FE/AE errors due to humidity and seal degradation
More corrosion-related electrical errors (tE, bE)
Acceleration of drain problems due to increased lint/debris in humid conditions
In hard-water regions (Adelaide, parts of Brisbane):
More IE errors (mineral buildup in inlet valve)
More OE errors (mineral deposits in filter and drain system)
We recommend monthly descaling cycles in these areas
In tropical climates (Brisbane, Cairns):
More false FE/AE triggers due to condensation
Faster seal degradation
Increased electrical component corrosion
In older Australian homes:
More OE errors due to aging home plumbing having backup issues
More installation-related issues if the machine was installed decades ago and never repositioned
Avoiding Most LG Error Codes
These habits keep LG dishwashers running error-free:
Scrape dishes thoroughly before loading -- Less debris reaching the filter
Clean the pump filter monthly if you run multiple loads per week
Use rinse aid -- Helps water flow cleanly, reducing sediment
In hard-water regions, run a descaling cycle monthly
Verify the machine is level annually -- Check that it hasn't shifted
Clean the door seal quarterly with warm soapy water
Don't overload excessively -- Affects water circulation
Keep the drain hose routed correctly -- No kinks, no compression
Frequently Asked Questions
Can I fix any LG error code myself, or do some always require a professional?
IE, OE, and FE/AE errors are often DIY-fixable (cleaning, straightening hoses, leveling). tE and bE errors (sensor and motor) almost always need professional service.
Is it worth calling a technician if I'm not sure which error code my dishwasher is showing?
Yes. Tell us the code and we can often diagnose over the phone. Sometimes the code display is unclear. We can help clarify and tell you if it's DIY-fixable.
How long do parts typically last before needing replacement in an LG dishwasher?
Filters and door seals: 8-10 years in humid climates, 12-15 years inland. Pumps: 10-15 years depending on use. Inlet valves: 12+ years unless affected by mineral deposits.
Are error codes more common in older LG models?
Older models (10+ years) show more errors as sensors become less accurate and seals degrade. But LG's error codes are reliable across all ages. If an error appears, it indicates a real problem.
Should I reset my LG dishwasher if an error code appears?
You can try unplugging for 5 minutes, then plugging back in. This clears some false error triggers. But don't keep resetting if the error returns -- that indicates a persistent problem needing diagnosis.

Your commercial refrigerator isn't holding temperature. Items that should be 2-4°C are sitting at 8°C. Your walk-in cooler is running constantly but not cooling adequately. Health inspectors are asking questions. Your food costs are rising as spoilage increases.
For restaurants, cafés, and food businesses, a failing cooler isn't an inconvenience -- it's a threat to health, reputation, and revenue.National Appliance Repairs works with commercial food operations across Australia, and we've learned that understanding what's wrong and how to respond quickly is essential. We'll walk you through the most common commercial cooling issues, what you can diagnose yourself, and when to call for emergency service -- because in food business, downtime costs money every minute.
Quick Troubleshooting Guide
Problem
Most Likely Cause
Immediate Action
Professional Diagnosis Needed
Temperature too warm
Condenser coils dirty, door seal failing, or compressor weak
Check and clean condenser coils. Inspect door gasket. Ensure door closes fully.
If still warm, compressor or refrigerant issue. Call immediately.
Compressor runs constantly but doesn't cool
Low refrigerant, faulty compressor, or overworked system
Check that condenser is clean and vents aren't blocked. Reduce ambient kitchen temperature if possible.
Professional diagnosis required. Refrigerant recharge or compressor replacement needed.
Frost or ice buildup inside
Defrost cycle failing or evaporator coils icing over
Check defrost timer settings. Run manual defrost cycle if available.
If frost returns, defrost system or evaporator coils failing. Call service.
Strange noises (grinding, rattling)
Compressor bearing wear, loose components, or vibration
Listen for location of noise. Check mounting bolts are tight.
If grinding or unusual noise continues, compressor or motor failing. Professional service needed.
Water pooling inside or underneath
Clogged drain line or failed evaporator
Check drain line for blockages. Clear if accessible.
If water returns, internal component failure. Professional service needed.
Causes of Temperature Problems in Commercial Refrigeration
Dirty condenser coils
Commercial kitchens are hot, dusty environments. Grease and dust accumulate on the condenser coils that release heat. When coils are clogged, the compressor can't release heat efficiently. The fridge works harder and cools less effectively.
This is the most common cause of temperature problems. Regular cleaning prevents it.
Failing door seal
Cold air escapes through a worn or loose gasket around the door. The compressor runs constantly trying to maintain temperature but can't keep up.
Inspect the gasket regularly. If it's hard, cracked, or visibly worn, replacement is needed.
Low refrigerant
If you have a refrigerant leak, the system can't absorb and remove heat effectively. The fridge won't cool adequately no matter how long the compressor runs.
Low refrigerant is a professional repair. You can't just "top it off." A technician must find and fix the leak, then recharge the system properly.
Compressor failure
The compressor is the heart of the refrigeration system. If it's failing, the fridge won't cool. A weak or failing compressor runs more and more but produces less cooling.
Compressor replacement is expensive ($800-2,000+ depending on the unit size) but necessary.
Overworked system
A fridge designed for normal kitchen volume might fail when operating in a busy restaurant during peak season. Constant door opening, new warm food being added, and running at full capacity 16+ hours daily creates stress.
You can't fix an overworked system without upgrading to larger capacity. But you can reduce stress by:
Minimizing door open time. Adding new food to the fridge in batches, not constantly. Ensuring the fridge isn't in direct sunlight or next to a heat source. Confirming adequate ventilation around the unit.
Defrost system failure
Walk-in coolers and larger commercial units have automatic defrost cycles. If the defrost timer or heating element fails, ice can accumulate on the evaporator coils. The ice insulates the coils, preventing cooling.
Manual defrost is a temporary fix, but the automatic system needs repair.
Immediate Response Steps
When you notice temperature problems:
Stop using the fridge for food storage immediately. Move perishables to backup refrigeration or coolers with ice. Don't guess whether food is safe. Err on the side of caution.
Document the problem. Note when you discovered it, what the temperature was, what food was inside, and how long the door might have been at unsafe temperature. This documentation matters if customers or health inspectors ask questions.
Call for emergency repair. Commercial fridge problems are genuinely urgent. Call your repair service immediately, even if it's evening or weekend. Explain that you have a health and safety issue. Most services respond quickly to commercial calls because they understand the stakes.
Check the obvious. Ensure the door is closing fully. Look at the condenser coils (usually at the back or bottom). If they're visibly clogged with dust and grease, cleaning them sometimes restores cooling temporarily. Don't attempt complex repairs, but basic cleaning is fine.
Prepare for emergency billing. Emergency commercial repair will be expensive. Budget for same-day service premium, labour costs, and parts. This is a business cost you have to absorb.
Maintenance to Prevent Problems
Clean condenser coils monthly. This is the single most important maintenance task. Coils clog quickly in kitchen environments. Monthly cleaning prevents the most common cause of temperature failure.
The coils are usually accessible at the back or bottom of the unit. Use a soft brush to gently remove dust and grease. Compressed air or a vacuum can help. If coils are heavily caked with grease, professional cleaning might be necessary.
Inspect the door gasket quarterly. Run your hand around the gasket. It should be flexible and soft. If it's hard, cracked, or loose, replacement is needed. A new gasket costs $100-300 and prevents expensive emergency repairs.
Ensure ventilation. The condenser needs air circulation to release heat. Don't block vents with boxes or equipment. Ensure adequate space around the fridge for air to flow.
Don't overload. Commercial fridges have capacity limits. Cramming in too much food reduces airflow and makes the compressor work harder. Respect the design capacity.
Service annually. Have a qualified technician inspect the unit annually. They check refrigerant charge, compressor operation, electrical connections, and overall system health. Annual service costs $150-300 but often catches problems before they become emergencies.
Keep temperature logs. Monitor the fridge temperature daily. Write it down. Temperature logs serve multiple purposes:
They alert you to problems early. A 1°C rise over a week tells you something is wrong before food spoils.
They document compliance for health inspectors.
They help technicians diagnose recurring problems.
Simple max/min thermometers (under $20) do this job. More sophisticated systems log temperatures automatically.

Cost context: New walk-in coolers cost $3,000-8,000+. Reach-in units cost $1,500-4,000. Repairs might cost $500-2,000. The economics matter for budgeting.
However, don't let cost prevent emergency repair when you have food at risk. Emergency repair now, budgeting for replacement later, is the right approach.
Working with Your Repair Service
When calling for commercial repair:
Be clear about the business impact. "We're losing revenue every minute this is down" helps services prioritize.
Provide specific temperature readings. "Holding at 10°C instead of 3°C" is more useful than "not cooling."
Ask about temporary solutions. Can they do an emergency charge to get you through until tomorrow? Can they provide recommendations for minimizing risk while you wait?
Discuss preventative maintenance options. Many repair companies offer commercial maintenance contracts. Regular service often prevents emergency failures.
Frequently Asked Questions
How fast can I get emergency repair for a commercial fridge?
In major Australian cities, 2-6 hours is typical for commercial emergencies. Rural areas might take longer. When you call, ask for estimated response time and confirm availability. Commercial repair services understand the urgency and often respond faster than residential calls.
Can I keep the fridge running if it's not cooling properly, or should I turn it off?
Turn it off. Running a failing compressor can cause additional damage. If you turn it off, food stays cold longer. If you keep running a failing system, you waste electricity and risk deeper damage.
What temperature should I maintain during normal operation?
Refrigerated food should be 0-4°C. Frozen food should be -18°C or lower. Check your fridge's thermostat and confirm it's set correctly.
How much does commercial fridge repair typically cost?
Emergency calls have a premium charge ($150-300). Parts vary widely: a new compressor costs $1,000-2,000+. A gasket costs $100-300. Labour is $50-100+ per hour depending on complexity. Budget $500-2,500 for typical emergency repairs.
If my fridge dies and I can't get emergency repair today, what do I do with the food?
Move perishables to coolers with ice immediately. Food stored at 5°C or cooler stays safe. Document what you did and when. Consult with your health department if you're unsure about food safety. Better to discard food than to serve unsafe product.

An OE error on your LG washing machine means one thing that stops everything: water isn't leaving the drum. You've got a full tub of wet clothes and a machine that won't finish its cycle. It's frustrating, it's wet, and it needs fixing now.
Here's what we've learned from thousands of OE error calls across Australia: in 70% of cases, you can actually solve this yourself in under 30 minutes.
What the OE Error Actually Tells You (From Our Experience)
The OE code (sometimes displayed as "DE" depending on your LG model) is your washing machine's drainage error signal. The machine's sensors detected that water should have drained but didn't. That's it -- it's not a mysterious electrical problem, it's a plumbing issue.
After 15+ years of LG repairs in Melbourne, Sydney, Brisbane, Perth, and Adelaide, we can tell you exactly what's happening inside that machine almost before we arrive.
The OE error means: Water is trapped. Find out why.
Your washing machine relies on a pump to actively push water out. If that pump can't do its job -- whether because the path is blocked, the pump is stuck, or the hose won't cooperate -- you get the OE code and a full tub.
What We Actually Find When We Diagnose OE Errors
The clogged drain pump filter. This is the most common culprit, especially in Australian homes. The filter sits at the bottom-left of most LG front-loaders, behind a small access panel. It traps lint, hair, coins, and debris before they reach the pump.
We open these things and find them absolutely packed. In one Brisbane home, we found a loose underwire from a bra wrapped around the impeller inside. In another Sydney apartment, there were three coins, a bobby pin, a pen cap, and enough lint to knit a small blanket.
The filter gets blocked, water can't flow into the pump, and the pump signals an error because it's trying to work but nothing's happening.
A kinked or blocked drain hose. The drain hose sits behind your machine, running from the tub to your sink drain or standpipe. If this hose gets kinked, twisted, or if something blocks it internally, water backs up in the drum.
We've found drain hoses compressed so tightly they were barely open. One customer in Adelaide had pushed her machine back against the wall, and the hose was crushed to maybe 30% of its normal diameter. Water was trickling out instead of flowing.
The drain hose installed backward. Some LG drain hoses have a built-in check valve (one-way flow). If someone reinstalled it during a move or renovation, they might have installed it backward. The valve now prevents water from flowing out.
A blocked drain system in your home. Sometimes it's not the washing machine at all. Your sink drain is clogged. Your home's plumbing has a blockage. The washing machine can pump water out, but it has nowhere to go, so it backs up into the tub.
We've had to refer customers to plumbers when the problem was their home's drainage system, not the LG.
Can You Fix This Yourself?
If the OE error appeared during the very first cycle after you filled the machine (meaning water was already in there before the cycle started), the problem is probably upstream -- your home's plumbing or the connection to the dishwasher if you have one.
If the OE error appears mid-cycle or after water has already been draining (you see water that's already dirty with soap), the problem is in the machine itself.
If you have a newer LG and the machine is still humming but not draining, the pump is engaged but blocked.
If you hear nothing -- total silence from the pump area -- the pump might not be engaging at all.
Step One: Stop the Cycle and Drain Manually
First, don't try another cycle. That water needs to come out.
Turn off your washing machine. Open the service panel (usually bottom-left corner, behind a small rectangular cover). You'll see a small drain hose with a cap or plug.
Place a bucket or shallow pan underneath. Unclip the hose and remove the cap carefully. Let water drain completely -- have towels ready because it can spill.
Once drained, proceed with troubleshooting.
Step Two: Clean the Drain Pump Filter (Fixes 60% of OE Errors)
This is where most OE problems solve themselves.
After you've drained the machine, look for the pump filter access. On most LG front-loaders, it's right there in the service panel area. You'll see a circular cap.
Turn it counterclockwise slowly (water might still be in there). Pull it out.
You'll find your culprit: lint, hair, debris, possibly small objects. In Australian homes, we frequently find coins and pieces of clothing labels.
Rinse everything under warm water. Use your fingers or an old toothbrush to clear the filter completely. The opening needs to be absolutely clear for water to flow.
Once clean and dry, screw the cap back in clockwise until snug. Don't over-tighten.
Now, run a spin-only cycle to test. The machine should drain without error.
If it works: You just fixed it. Congratulations.
Step Three: Inspect the Drain Hose
If the filter was clean but the machine still won't drain, the hose is your next suspect.
Unplug the washing machine first. Find where the drain hose connects at the back. Trace it to where it connects to your home's drain system.
Look for:
Kinks or twists -- Straighten gently. A small kink is enough to block flow.
The hose crushed against the wall -- Move the machine out slightly and reposition the hose
Internal blockages -- If you suspect something's stuck inside, disconnect the hose at both ends (have a bucket ready) and run hot water through it
Check how it's positioned. The hose should rise from the machine, then descend into your drain. If it dips below the machine connection level, siphoning can prevent drainage.
Step Four: Check Your Home's Drain Connection
Make sure the drain hose isn't submerged in water inside your sink. If the end of the hose is sitting in standing water, that water can siphon back into the machine.
The hose should be inserted 5-10cm into the sink drain or standpipe, not submerged.
Also check: Is your kitchen sink draining slowly? If so, your home's plumbing is likely the culprit, not the washing machine. Clear the sink drain or contact a plumber.
Step Five: Run a Test Cycle
After addressing the filter or hose, unplug the machine for 5 minutes. This resets the error code.
Plug it back in and run a spin-only cycle. Listen for the pump to engage (you'll hear it humming). Watch to see if water actually drains.
If water drains and there's no error, you've fixed it.

When the OE Error Keeps Coming Back
If you've cleaned the filter, straightened the hose, and checked your home's drainage but the OE error returns after 24 hours, you're dealing with something more complex:
The pump motor might be failing. If the pump is humming but water isn't moving, the impeller inside could be damaged or stuck.
The pressure sensor could be faulty. This sensor detects when water has drained. A broken sensor sends false signals to the control board.
The control board could be malfunctioning. The board tells the pump when to engage and when to stop. A glitch could prevent proper drainage signalling.
Your home's plumbing might have a deeper issue. A blockage in the main drain line requires a plumber, not an appliance technician.
This is when professional LG washing machine repair makes sense. Our technicians can diagnose whether it's a pump replacement, sensor issue, or a plumbing problem requiring a plumber.
National Appliance Repairs services all LG washing machine models and carries genuine replacement parts. We provide a 12-month parts warranty on all repairs.
What We've Learned From LG OE Errors Across Australia
Hard water regions are worse. Adelaide especially has mineral buildup that accelerates filter clogging. We recommend running a tub clean cycle monthly in hard water areas.
Coastal humidity matters. Sydney and Perth have higher moisture content in the air. Lint accumulates faster in humid climates. Clean the filter more frequently if you live near the coast.
Older Australian homes with aging plumbing cause more OE errors than the washing machine itself. We've had to refer countless customers to plumbers when the issue was their home's drain system, not the LG.
Using too much detergent creates suds that block the drain pump. This is the #2 cause of OE errors we see. HE washers especially require much less detergent than people use. If you're using a quarter-cup when you should be using a tablespoon, you're creating problems.
Leaving small items in pockets is a real problem. Coins account for maybe 20% of the filter blockages we find. The coin itself doesn't block much, but it catches lint and hair around it, building a dam inside the filter.
Stop OE Errors From Happening
Simple habits prevent most OE errors:
Clean the drain filter monthly if you run the machine frequently -- it takes 5 minutes
Check pockets thoroughly before loading (coins, pens, bobby pins all end up in the filter)
Use the correct detergent amount -- measure it, don't just guess. HE detergent should be 1-2 tablespoons per load, not a quarter-cup
Run a tub clean cycle monthly to prevent buildup in the pump area
Inspect the drain hose annually for kinks or damage
Don't push the machine tight against the wall -- leave at least 10cm of space behind for the drain hose to breathe
Run hot water cycles occasionally to help flush mineral deposits (especially important in Adelaide and hard water regions)
Frequently Asked Questions
Is the OE error always fixable without calling a technician?
About 70% of the time, yes. Clogged filter or kinked hose are DIY-fixable. If the filter is clean and the hose is straight, you're looking at a pump issue that needs professional service.
What's the difference between OE and IE error codes?
OE is drainage (water won't come out). IE is inlet (water won't come in). OE is more common and usually fixable. IE often requires inlet valve repair.
Should I keep trying to run cycles while the OE error is happening?
No. Stop using the machine. Each cycle adds water that can't drain, risking overflow or water damage. Drain manually first, then troubleshoot.
How do I prevent the OE error from coming back?
Clean the filter monthly, check the drain hose yearly, and use the correct amount of detergent. Too much detergent creates suds that block the drain.
Is a clogged filter an expensive fix?
Not expensive. It's free if you clean it yourself (takes 5 minutes). If we do it professionally, it's just a service call fee ($100-150). No parts replacement needed.
The Bottom Line
The OE error is your LG's way of saying "I'm trying to drain but something's stopping me." In most cases, that something is a clogged filter or kinked hose -- both things you can fix yourself in 30 minutes.
Start there. Clean the filter. Straighten the hose. Test the cycle.

An F11 error on your Miele dishwasher is a drainage fault code, and if you own a Miele, you probably know that this appliance cost you serious money. You didn't buy it to sit idle.
Here's what we've learned from servicing Miele dishwashers across Australia for 15+ years: an F11 error is more likely to be a legitimate repair issue than some of the simpler error codes on other brands. Miele builds precision machines, and when they report a problem, it's usually genuine.
This doesn't mean you need to panic. But it does mean the diagnostic process is more technical, and you need to know when professional service is actually required.
What the F11 Code Specifically Means (In Miele's Language)
Miele's error codes are specific. F11 translates to "Drainage Fault" with a particular implication: the machine has attempted drainage multiple times and detected that water is present when it shouldn't be.
Unlike some other brands that throw drainage codes at every minor issue, Miele's pressure sensor is calibrated to be more selective. If a Miele is reporting F11, it's not being overly sensitive.
After servicing hundreds of Miele dishwashers across Melbourne, Sydney, Brisbane, Perth, and Adelaide, we found that the filter in your Miele's drain system is blocked or the non-return valve is stuck.
These are precision components, and Miele's engineering expects them to work perfectly. When they don't, the machine stops rather than forcing water through and causing internal damage.
The drain hose is kinked or blocked, preventing water from flowing into your home's drainage system at the rate the machine expects.
Your home's plumbing has a backup, and water is pooling where the dishwasher tries to drain into it.
The pressure sensor itself has malfunctioned, incorrectly signalling that water is present.
The Diagnostic Process: What We Do Before Recommending Parts
Here's where Miele owners need to understand something: we don't just swap components. We diagnose.
A Miele costs between $2,000-$5,000+ new. You didn't buy it for quick fixes. You bought it because it's engineered to last 20 years. Our approach respects that investment.
When we get an F11 call, we follow this process:
First, we check if this is an actual Miele problem or a plumbing problem. We ask specific questions: Where is the dishwasher draining? Is your sink draining properly? Have you noticed slow drainage elsewhere in your home?
If the sink is slow, it's your home's plumbing. We refer you to a plumber. Miele can't fix a backed-up drain line.
Second, we confirm the error is reproducible. We ask if the F11 appears every cycle or occasionally. A consistent error suggests a component issue. An intermittent error might be a sensor glitch.
Third, we identify which generation/model of Miele you have, because the internal components vary. A G1xxx series has different internal architecture than a G6xxx or G7xxx. The non-return valve location, filter type, and drain configuration differ.
What We Actually Find When We Service F11 Errors
The filter blockage. Most Miele dishwashers have a fine mesh filter at the base of the drain system. It's designed to catch food particles and prevent them from reaching the pump or non-return valve.
Over time, especially if you pre-rinse poorly (or don't pre-rinse at all), this filter accumulates debris. We regularly find filters so blocked that water can barely trickle through.
What surprises Miele owners: the filter can look relatively clean from above but be completely clogged from the underside where food particles have compressed against the mesh.
We clean it by running water upward through the mesh (opposite to normal flow direction) which dislodges the packed-in debris.
The non-return valve stuck closed. This is the Miele-specific component. Most dishwashers have a simple one-way flap or ball valve. Miele's non-return valve is more sophisticated -- and more prone to sticking if mineral deposits or food particles jam it.
When this valve sticks, water backs up into the tub even though the pump is working correctly. The pressure sensor detects this backup, and F11 appears.
We inspect it by removing the drain hose assembly and checking the valve's movement. A stuck valve needs to be cleaned or replaced.
Mineral deposits in the drain system. If you live in Adelaide or other hard-water regions of Australia, mineral buildup is a real problem. We've opened Miele drain systems where calcium deposits have restricted the drain path to a fraction of its normal diameter.
This doesn't happen overnight. It takes years of hard water running through the system. But once it starts, it accelerates.
A damaged pressure sensor. On newer Miele models, the pressure sensor is electronic. It can malfunction. But here's the thing: Miele's diagnostics are so good that a faulty sensor usually generates a different error code (often F13 or F14). F11 specifically points to an actual drainage issue more often than it points to the sensor.

The Honest Assessment: Can You Fix This Yourself?
For a Miele, the answer is usually "no" without risking something more expensive.
The filter? You might be able to access and clean it if you're mechanically inclined and have the manual. The service manual exists online for most Miele models.
The non-return valve? This is where it gets risky. The valve is a precision component. If you disturb it incorrectly, you could damage the seal or the spring mechanism. That's a $200+ replacement rather than a $50 professional cleaning.
We tell every Miele owner that if the F11 error started suddenly (you were running it fine yesterday), it's likely the filter. Try this: Access your manual and locate the filter. Run warm water through it from underneath (opposite direction). If water suddenly flows easily and the error disappears, you found it.
If the F11 error started gradually (cycles were taking longer and longer), it's likely mineral buildup or a stuck valve. This needs professional attention.
If you live in a hard-water region (Adelaide, some parts of Brisbane, Perth), and you haven't had the drain system serviced in 5+ years, it's time. Preventative maintenance costs $150-$200. Ignoring it until the valve is completely blocked costs $500+.
What Actually Fixes F11 (When We Diagnose It)
Filter cleaning: We access the filter, inspect it, and run water through it from both directions to dislodge debris. Takes 30 minutes. Most common fix for F11.
Non-return valve cleaning: We remove the drain hose assembly, inspect the valve, and if it's stuck, we carefully clean it or -- if it's damaged -- replace it. Takes 1-2 hours depending on valve type.
Non-return valve replacement: If the valve is damaged or the seal is compromised, we replace it with a genuine Miele component. Not cheap ($250-$350 for the part), but it restores your dishwasher to factory specifications.
Drain hose inspection and repositioning: We check the entire drain path, ensure the hose isn't kinked, and confirm it connects to your home's plumbing correctly. Sometimes this alone fixes it.
Pressure sensor replacement: If diagnostics confirm the sensor is faulty (rare for F11, but possible), we replace it with a genuine component.
All repairs come with a 12-month parts warranty.
Regional Considerations for Australian Miele Owners
Hard water regions (Adelaide, parts of Brisbane, Perth): If you haven't had your Miele serviced in 5+ years, schedule preventative maintenance now. Mineral buildup in the drain system is inevitable in hard water.
Coastal areas (Sydney, Perth): Salt air doesn't typically affect internal drain components, but high humidity can accelerate corrosion on the metal valve housing. Make sure your drain hose isn't exposed to constant moisture.
Older Australian homes with aging plumbing: We've serviced Miele dishwashers in 1960s homes where the plumbing is the actual problem, not the appliance. The dishwasher is trying to drain into a system that's backed up or has a blockage elsewhere.
High-use households (large families): If you're running the dishwasher 2+ times daily, the filter needs cleaning more frequently. We recommend monthly filter checks for heavy users.
Keeping Your Miele Draining Perfectly
Miele owners are thoughtful about maintenance. These practices keep F11 from appearing:
Pre-rinse or scrape thoroughly -- This is the #1 prevention. Most food particles should be removed before loading. Less debris reaching the filter means fewer blockages.
Clean the filter quarterly -- Access it, inspect it, run water through it. Takes 10 minutes. Prevents buildup.
Run the machine with a full load -- Partial loads create uneven water distribution and can increase sediment reaching the filter.
Use rinse aid -- Miele recommends this for a reason. It helps water flow off dishes cleanly, reducing sediment.
In hard-water regions, run a descaling cycle every 3 months -- Your manual specifies the descaling process. This prevents mineral buildup in the drain system.
Don't force the drain hose -- If your plumbing connection is tight, take time to position the hose properly. Don't kink it or compress it.
Have the drain system serviced every 5 years -- Even in soft-water regions. This is preventative maintenance that costs $150-$200 now or $500+ when something fails.
Frequently Asked Questions
Is the F11 error always a major repair?
No. About 50% of the time it's just a clogged filter that needs cleaning. Some F11 errors are simple drain positioning issues. However, Miele's precision means it's more likely to need professional attention than other brands.
What's a non-return valve and how much does it cost to replace?
It's a one-way valve that prevents water from flowing backward into your dishwasher. If it's stuck, water backs up and triggers F11. Replacement typically costs $200-300 for the part plus labor.
Is preventative maintenance really necessary for a Miele?
In hard-water regions, yes. Adelaide and hard-water areas should have the drain system professionally serviced every 5 years ($150-200). This prevents the mineral buildup that causes F11 errors later.
Can I pre-rinse dishes in a Miele?
Miele doesn't require pre-rinsing, but light scraping helps. Heavy food particles should be removed. This reduces debris reaching the filter and prevents many drainage issues.
How long should a Miele last before needing major repairs?
With proper maintenance, a Miele typically lasts 15-20 years. If you're getting repair calls before 10 years, something is genuinely wrong worth fixing. After 15 years, evaluate whether ongoing repairs make sense.
The Miele Difference
You own a Miele because it's built to last. It's precise. It's German engineering. And it deserves professional service from technicians who understand that level of quality.
An F11 error isn't a minor inconvenience on a Miele -- it's the machine telling you something specific is wrong. We take that seriously. We diagnose carefully, we use genuine parts, and we get your Miele back to the standard you expected when you bought it.
