An IE error on your LG washing machine means the machine failed to fill with water within the expected timeframe. It's one of the more common fault codes on LG front-loaders and top-loaders, and in a lot of cases it can be cleared without a service call. That said, some causes require professional attention. This guide covers what triggers the IE code, what you can safely check yourself, and when it's time to call in a technician.
National Appliance Repairs services LG washing machines across Melbourne, Sydney, Brisbane, Perth, and Adelaide – with same-day appointments available in most metro areas.
What Does the IE Error Code Mean?
IE stands for Inlet Error. The machine's control board monitors how quickly the drum fills with water. If the preset water level isn't reached within a set time – typically around eight minutes for the initial fill and up to 25 minutes overall – the board flags an IE code and stops the cycle.
On some LG models the code appears as 1E rather than IE, but the meaning is identical. Both indicate a water supply or inlet system fault.

Step-by-Step Troubleshooting
1. Check the Water Supply Tap
The most straightforward fix: confirm the tap supplying the machine is fully open. A tap that's only partially open restricts flow enough to trigger IE, especially on larger load cycles that require a higher fill level.
2. Inspect the Inlet Hose
Pull the machine out from the wall and check the hose running from the tap to the back of the washer. A sharp bend, kink, or a section pinched behind the machine will restrict flow significantly. Straighten the hose and reposition the machine, leaving enough clearance so the hose sits without pressure.
3. Clean the Inlet Filter Screens
Inside the water inlet valve – where the hose connects at the back of the machine – there are small mesh filter screens designed to catch sediment and debris. Over time these clog, particularly in older homes or areas with harder water. To clean them:
Turn off the water supply tap and unplug the machine.
Unscrew the inlet hose from the back of the machine.
Pull out the filter screen with needle-nose pliers.
Rinse the screen under running water, removing any sediment or calcium build-up.
Reinstall the screen, reattach the hose, and check the connection is watertight before turning the tap back on.
4. Check Mains Water Pressure
LG washing machines generally require a minimum water pressure of around 30–100 kPa to fill correctly. In some older apartment buildings – common in parts of inner Sydney and Melbourne – water pressure can be lower than this, particularly during peak morning periods. If you suspect low pressure, check whether other taps in the house are also running slowly. A licensed plumber can measure your pressure and advise on a booster pump if needed.
5. Allow Frozen Lines to Thaw
In colder parts of Australia – alpine areas of Victoria and NSW, elevated parts of the ACT – supply lines can freeze overnight in winter. If the machine runs fine at other times of year but throws an IE error in the morning during cold snaps, a frozen inlet line may be the cause. Allow the area around the supply line to warm before using the machine.
6. Test the Water Inlet Valve
The inlet valve is a solenoid-operated component that opens to let water in and closes to stop flow. If the mesh filter is clean and the water supply is confirmed adequate but the machine still won't fill, the valve itself may have failed. Replacing it involves opening the machine cabinet and working with electrical connections, so this step is best handled by a qualified technician.
7. Pressure Sensor or PCB Fault
In some cases the machine is actually filling correctly but the pressure sensor (which measures the water level) is giving a false reading to the control board. If all the above checks come back clear and the IE error persists, the fault lies with the sensor or the main PCB.
Frequently Asked Questions
What does IE mean on an LG washing machine?
IE stands for Inlet Error and means the machine wasn't able to fill with water to the required level within the set time. The most common causes are a partially closed tap, a kinked inlet hose, or blocked filter screens on the inlet valve.
Can I fix the LG IE error myself?
Many IE errors can be resolved at home by opening the supply tap fully, straightening a kinked hose, or cleaning the inlet filter screens. Faults involving the inlet valve, pressure sensor, or wiring require a licensed appliance technician.
Will the IE error clear itself?
The error won't clear on its own – it requires the underlying fault to be fixed before the machine will run. Once the cause is addressed, unplug the machine for 30 seconds and restart to reset the fault code.
How do I clean the inlet filter on an LG washing machine?
Turn off the water supply, disconnect the hose from the inlet at the back of the machine, and pull out the small mesh screen with pliers. Rinse the screen under running water to remove sediment, then reinstall before reconnecting the hose.
How much does it cost to fix an LG washing machine IE error?
If the fix is a kinked hose or partially closed tap, there's no cost at all. A blocked inlet filter takes around 15 minutes to clean yourself. If the inlet valve itself needs replacing, expect a parts cost plus a labour charge from a technician.
When to Call a Technician
If you've checked the tap, hose, and inlet filters and the IE error is still appearing, the fault is likely inside the machine – either the inlet valve, pressure sensor, or PCB. These components require specialist tools and knowledge to diagnose accurately.

A small puddle under the dishwasher is easy to dismiss as a one-off. It usually isn't. Left alone, water works its way into floorboards, swells cabinetry from the inside, and creates mould in the grout around the base. The longer it keeps leaking, the more expensive the fix becomes -- and that's before you've touched the dishwasher itself.
The good news is that the source of the leak usually isn't hard to find. Where the water appears tells you a lot before you've even opened anything up. For repairs across Sydney, Melbourne, Brisbane, Perth, and Adelaide, National Appliance Repairs offers same-day call-outs with a 12-month warranty on all parts.
Finding the Source
Get down with a torch while the machine is running -- or just after it finishes draining -- and watch carefully. Water that "comes from under the dishwasher" often turns out to be running down the inside of the door, spreading along the floor tiles, and pooling near the machine's base. That's a door seal problem, not an internal one. The two have different fixes.
Water tracking along the front edge of the door -- door seal or door alignment
Water pooling directly underneath the machine -- pump seal, sump gasket, or drain hose
Water appearing near the connection at the back -- inlet hose fitting
Water during the fill phase rather than the drain -- float switch or inlet valve
Door Seal (Gasket)
The most common cause, by a clear margin. The rubber or silicone seal around the door perimeter keeps water inside the tub during a wash cycle. Over time it flattens, cracks, or collects debris at the base that breaks the seal. Water then escapes during the wash cycle, runs down the door face, and spreads across the floor -- making it look like a bottom leak.
Run your finger around the full length of the gasket and check for:
Visible cracks or tears
Sections that have pulled away from their channel
Food debris or dried detergent built up in the bottom corners (this is where most gasket leaks actually start)
Flat spots where the rubber has lost its original shape
Cleaning the gasket with warm soapy water often fixes debris-related leaks immediately. A damaged or permanently deformed gasket needs replacing. Replacement gaskets for most brands cost $40--$80 and press into the door channel without special tools.
Door Alignment and Machine Level
A door that doesn't close square will press the gasket unevenly, creating a gap even when the gasket itself is undamaged. This happens when the machine gets knocked, when it wasn't properly secured to the cabinetry during installation, or simply when the levelling legs have worked loose.
Place a spirit level on top of the machine and check it both front-to-back and side-to-side. An unlevel machine allows water to overflow at one side of the tub during the wash cycle, which exits under the door. Adjust the levelling legs -- usually accessible from the front under the kickplate -- until the bubble centres in both directions. Also check the door closes with a firm, even click.
Pump Seal and Sump Gasket
If the water is genuinely coming from underneath rather than tracking from the door, the pump or sump is the next place to look. The sump collects water at the base of the tub before the pump clears it. The seal around the sump, and the seal where the pump attaches to it, both wear with age and heavy use.
This leak typically only becomes visible if you remove the kickplate and look underneath with a torch while the machine runs a full cycle. You won't see it from above.
Accessing and replacing a pump seal requires partially disassembling the pump assembly. Putting it back together incorrectly causes more leaks or damages the pump motor. This one needs a technician.
Drain Hose
The drain hose carries water from the pump to the sink drain or waste outlet. It can develop a split, a clamp can work loose, or (very commonly) it ends up in the wrong position: either compressed against the back of the cabinet, or with the outlet end sitting submerged in water under the sink. Both cause leaks or backflow.
While a cycle is running, pull the machine out slightly and look at the drain hose:
Any water dripping from the hose body or at either connection point
Whether the hose end sits submerged in standing water under the sink
Whether the hose has a proper elevated loop before dropping to the drain connection -- it should rise close to bench height before going down
A cracked hose can usually be replaced as a DIY job. Incorrect routing causing backflow just needs the hose repositioned.
Float Switch
Inside the tub, near the front, is a small float dome. It rises with the water level and triggers a switch that tells the inlet valve to stop filling. If the float jams down -- food debris is almost always the cause -- the valve stays open and the machine overfills. Water spills over the tub edge and exits under the door.
Press the float up and down. It should move freely without resistance. If it's stuck, clear the debris and test again. If the microswitch beneath it has failed, the switch itself needs replacing.
Too Much Detergent
Excess detergent creates foam that the machine reads as water volume. The suds build up until they're forced out under the door. If the leak is consistent and you notice foam in the tub or at the base of the door, reduce the detergent quantity. In soft-water areas, the recommended amount on the packaging is usually too much -- try using significantly less and see whether the foam disappears.

FAQ
Can I keep using the dishwasher while it's leaking?
It's not a good idea. Every cycle adds more water to the floor and cabinetry. A minor leak can become a floor replacement job in a few weeks.
Can I replace a door gasket myself?
Usually, yes. Most gaskets press into a channel and don't need tools. Order the correct part for your model, warm the new gasket with a hairdryer on low heat to make it pliable, and press it in firmly starting at the top centre.
Why does my dishwasher only leak sometimes?
Intermittent leaks often point to an overfill issue (float switch or inlet valve), foam from excess detergent, or a door seal that only fails at certain water pressures or during particular wash phases.
How do I check if the dishwasher is level?
Set a spirit level on top and check it both front-to-back and side-to-side. Adjust the levelling legs under the kickplate until it sits flat in both directions.
What's the difference between a pump seal leak and a door seal leak?
A door seal leak tracks down the door face and spreads across the floor. A pump seal leak appears directly underneath the machine and is only visible with the kickplate removed. They look similar from across the kitchen but have completely different fixes.
Conclusion
Most dishwasher leaks start at the door seal. Clean it first, check for damage, and confirm the machine sits level. If the water is coming from underneath rather than the door, the pump seal or drain hose needs a proper look -- and that work is better handled by a technician to avoid making things worse.

When a Smeg dishwasher develops a fault, it says so directly – E1 through E9, each code pointing to a different system. Some halt the cycle on the spot; others wait until the programme finishes. The code on the display is the starting point for every diagnosis, and this guide covers what each one means and what to do about it.
National Appliance Repairs repairs Smeg dishwashers across Australia, with same-day appointments available in most metro areas including Melbourne, Sydney, Brisbane, Perth, and Adelaide.
How Smeg Error Codes Work
Not all Smeg alarm codes behave the same way. E1, E2, E3, E4, E8, and E9 stop the cycle on the spot. E5 and E6 pause it – but if you address the cause mid-cycle, the machine picks up where it left off rather than requiring a restart. E7 is the exception: it doesn't interrupt the wash at all, appearing only at the end as a warning about the flow meter.
A door open-and-close or a power cycle at the wall will clear the display. If the same code reappears, the reset hasn't fixed anything – it's just confirmed the fault is real.

E1 / E9 – Overfill and Flood Switch Activation
E1 and E9 both relate to water exceeding the safe level. E1 activates when the flood prevention float switch in the base pan is triggered and stays closed for more than five seconds. Common causes: a faulty inlet valve that keeps filling after the fill phase, a blocked filter preventing drainage, or excessive foam from wrong detergent. If you've accidentally used regular dish soap, open the door and allow the foam to settle. For E9, check the base pan for water accumulation before restarting.
E2 – Overfill via Pressure Switch
E2 indicates overfilling via the pressure switch – the component that monitors water level. If the switch gives an incorrect reading, it can report an overfill even at normal levels. Check the wiring and connections between the switch and the PCB. A faulty pressure switch typically needs replacing.
E3 – Heating Fault
The machine took too long to heat the water – less than 1.5°C increase over 20 minutes is the threshold. A failed heating element or faulty heater relay is the most common cause. Test the element resistance with a multimeter, and confirm the spray arms rotate freely, as restricted water circulation can also prevent the machine from reaching temperature.
E4 – NTC Temperature Sensor Fault
The NTC sensor circuit has an open circuit or short at startup. Check all electrical connections at the sensor and the PCB. If connections are secure, measure sensor resistance against the manufacturer's specification. A faulty sensor needs replacing.
E5 – Water Fill Issue
The machine isn't receiving enough water. E5 pauses the programme and resumes it once the cause is corrected. Check the supply tap is fully open, the inlet hose isn't kinked, the mesh filter on the inlet valve isn't blocked, and that mains water pressure is adequate (typically 30–800 kPa). In hard water areas – common in parts of outer Perth and Adelaide where bore water is used – the mesh filter accumulates scale faster and should be checked more frequently.
E6 – Drain Fault
The machine couldn't drain within the set time. A blocked filter is the most frequent cause. To address it: unplug the machine, remove the lower basket and filter assembly, rinse both filter sections thoroughly under hot water, and inspect the drain pump for debris. Also check the drain hose for kinks and confirm it isn't immersed in standing water at the waste connection. Running a hot empty cycle monthly significantly reduces the frequency of E6 faults.
E7 – Flow Meter Fault (Warning Only)
The flow meter turbine, which monitors water consumption during the cycle, has reported a problem. Importantly, E7 doesn't stop the wash – it appears at the end of the cycle as a warning. The machine can complete the programme even with a faulty flow meter turbine, but the fault should be investigated. If the turbine is confirmed faulty it will need replacing; in some cases, a wiring issue at the turbine connector is the actual cause.
E8 – Wash Pump Fault
The wash pump – which circulates water through the spray arms during the wash cycle – has stalled or failed. Check the pump for any foreign objects that may be blocking the impeller. If the impeller is clear but the pump still won't run, the motor itself has failed and needs replacing. A failed wash pump is a professional repair.
Frequently Asked Questions
What does E1 mean on a Smeg dishwasher?
E1 means the flood switch in the base of the machine has been activated, indicating an abnormally high water level. This is usually caused by a faulty inlet valve that isn't closing, a blocked drain causing water to back up, or excessive foaming from incorrect detergent.
How do I reset a Smeg dishwasher after an error code?
Open and close the door, or turn the machine off at the power point and back on. If the same code reappears, the underlying fault needs to be fixed rather than cleared.
What causes E6 on a Smeg dishwasher?
E6 is a drain fault, most commonly caused by a clogged filter at the bottom of the tub or a blockage in the drain pump. Clean the filter, inspect the pump for debris, and check the drain hose for kinks or incorrect installation.
Can I use Smeg dishwasher while it shows E7?
Yes – E7 is a warning displayed at the end of the cycle and doesn't stop the machine from completing a wash. However, the flow meter fault should be investigated and repaired to prevent further issues.
Which Smeg error codes require a technician?
Codes involving the heating element (E3), temperature sensor (E4), wash pump (E8), and persistent drain or fill faults after DIY checks (E5, E6) generally require a qualified technician. E1 and E2 can sometimes be resolved by addressing detergent foaming or clearing a blocked filter, but a leak or faulty inlet valve is a professional repair.
Smeg Dishwasher Fault Doesn't Match This List?
Not all Smeg dishwashers use alphanumeric codes. Older and some mid-range models communicate faults through patterns of flashing lights rather than E-series codes on a display. If that's what you're seeing, the combination of which lights are flashing and how many are lit will point to the fault – your model's user manual is the most reliable reference for interpreting them.

An E24 error on your Bosch dishwasher is a drainage fault. The machine is reporting that water should have drained during a particular phase of the cycle, but it detected water still present in the tub.
After 15+ years of Bosch service calls across Australia, we can tell you this: Bosch's error codes are accurate. If your Bosch is showing E24, there's a genuine drainage issue. Bosch machines aren't prone to false positives like some brands.
The good news? The fix is usually straightforward.
What Makes Bosch E24 Different From Other Drainage Errors
Bosch uses different pressure sensing technology than many competitors. The E24 code specifically indicates the machine has detected water at a point in the cycle where drainage should be complete.
This is more precise than a generic "drainage problem" error. Bosch is telling you: "Drainage started but didn't finish. Something is blocking the water from leaving."
In our experience, this points to one of three specific issues:
A blockage in the dishwasher's internal drain path (filter, pump, or internal hose).
A blockage or obstruction in the external drain hose or your home's plumbing.
A failing pump that can't generate enough pressure to move water out.
We can usually diagnose which one over the phone by asking about when the error appears and how the machine sounds.

What We Actually Find When We Service Bosch E24 Errors
The internal pump filter clogged. This is the #1 culprit in Bosch dishwashers, accounting for roughly 65% of E24 errors we diagnose. Bosch filters are fine-mesh, designed to catch small particles. They're effective -- maybe too effective, because they get blocked easily.
We open Bosch machines and find filters absolutely packed with debris. Food particles, bits of broken glass (from broken dishes), fibers from sponges, sand from vegetables. In an Adelaide home, we found a filter so clogged with mineral deposits (hard water buildup) that water could barely trickle through.
The filter looks small and innocent from the outside. But internally, it's working hard and accumulating everything.
The pump itself impaired or worn. Bosch pumps are robust, but after 10+ years of constant use, they wear. The impeller (the spinning part) can become less efficient, moving water more slowly. This might not cause an immediate failure, but it can cause partial drainage that triggers the E24 code.
We've found pumps where the impeller had visible wear grooves from years of pushing water and debris.
The drain hose kinked or blocked. Bosch machines route the drain hose in a specific way. If it's been moved, renovated around, or if something has come loose, the hose can kink right where you can't see it.
We regularly find the hose twisted at an angle inside the cabinet space, restricting flow.
A partially blocked non-return valve. Some Bosch models (especially older ones) have a one-way valve in the drain circuit. If this valve has debris caught in it or mineral deposits restricting the opening, water backs up.
Your home's drain system. This accounts for about 15% of E24 errors we see. The dishwasher is trying to drain, but your sink is clogged or your home's plumbing is backed up. The dishwasher can't push water into an already-full pipe, so water backs up into the tub.
What We Do to Fix E24
1. Remove Standing Water
First, we drain any water still in the tub. We locate the emergency drain hose (usually at the bottom of the machine, bottom-left), place a bucket underneath, and let it flow.
2. Access the Pump Filter
We open the service panel and locate the pump filter chamber. This varies by model, but it's usually accessible from the bottom front.
3. Inspect and Clean the Filter
This is where we almost always find the problem. We remove the filter, and if it's blocked, we clean it thoroughly.
For stubborn blockages, we soak the filter in hot water for 15 minutes, then use a soft brush to clear debris. We never use harsh scrubbing that could damage the fine mesh.
4. Test the Pump
If the filter is clean, we run water through the pump chamber to ensure it's flowing. We listen for the pump to engage and verify water is actually moving.
5. Check the Drain Hose Path
We follow the entire drain hose from the machine to where it connects to your plumbing. We straighten any kinks and ensure it's routed correctly.
6. Run a Test Cycle
After addressing the blockage (or replacing the pump if necessary), we run a short cycle to verify drainage works. No error code means it's fixed.
When You Can Handle E24 Yourself
If you're mechanically inclined and comfortable accessing your dishwasher's internal components:
Consult your Bosch manual (available online for most models). Locate the pump filter. Remove it carefully. Rinse it thoroughly under warm water, paying special attention to clearing the fine mesh.
If the filter was visibly blocked and clogged, cleaning it alone might solve the E24 error. Run a test cycle.
If the filter was clean or cleaning didn't solve it, stop there and call us. The problem is the pump, the valve, or your home's plumbing -- all requiring professional diagnosis.
Don't attempt:
Disassembling the pump itself
Cleaning the internal drain hose without proper tools
Forcing anything apart to access components
Testing the pump's electrical connections
These require proper equipment and training.
Avoiding E24 Errors
These habits keep Bosch dishwashers draining properly:
Pre-rinse or scrape dishes thoroughly -- Less debris reaching the filter means fewer blockages
Clean the pump filter quarterly if you run the machine frequently
Use rinse aid -- Bosch recommends this, and it helps water flow cleanly, reducing sediment
Run the machine with full loads -- Partial loads create uneven water distribution
Don't overload excessively -- It affects circulation and drainage
In hard-water regions, descale monthly -- Use a commercial dishwasher descaling product to prevent mineral buildup
Have the machine serviced every 3-5 years -- Professional maintenance catches problems early
Frequently Asked Questions
What's the difference between Bosch E24 and other brand drainage errors?
Bosch codes are very specific. E24 means drainage was attempted but didn't complete. This precision helps us diagnose quickly. Most E24 errors are filter blockages, not pump failures.
How much does it cost if the filter is clogged vs. if the pump failed?
Filter cleaning: just a service call ($100-150). Pump replacement: $400-600 total. It's worth doing the filter check first since it solves 65% of E24 errors.
Can hard water cause E24 errors more frequently?
Yes. In Adelaide and hard-water regions, mineral deposits accumulate faster in the filter. We recommend descaling your Bosch monthly in hard-water areas and having the filter professionally cleaned annually.
Is it safe to run the dishwasher if it's showing an E24 error?
We don't recommend it. Each cycle adds water that won't drain, risking overflow, water damage, or worse blockages. Troubleshoot first, then run a test cycle.
Can E24 be a plumbing problem, not a dishwasher problem?
Yes, about 15% of the time. If your sink drains slowly or your home's plumbing is backed up, the dishwasher can't drain even if it's working fine. Check your sink first.
The Bosch Advantage
Bosch machines are built to last. The E24 error, while frustrating, usually indicates a fixable problem -- not a catastrophic failure. In our experience, most E24 errors are resolved with filter cleaning or a drain hose adjustment.
The machine itself is fine. Something is just blocking the water's path.

Westinghouse dishwashers communicate faults through a straightforward F-series code system – F1 through F9, each pointing to a specific subsystem. That means when something goes wrong, you're not guessing. You know exactly which part of the machine to look at.
National Appliance Repairs services Westinghouse dishwashers across Australia, with same-day appointments available in Melbourne, Sydney, Brisbane, Perth, and Adelaide when a job needs more than a DIY fix.
How to Read a Westinghouse Dishwasher Error Code
The display will show a code between F1 and F9. Each maps directly to a subsystem – drainage, heating, water inlet, and so on – so there's no ambiguity about where to start looking.
First, try switching the machine off at the power point, waiting 30 seconds, and turning it back on. Intermittent faults caused by power fluctuations or sensor glitches can clear this way. If the code reappears, the machine is telling you something genuinely needs attention – and this guide will walk you through each one.
Water in base pan – leak from hose, door seal, or internal component
F2
Drain Fault
Blocked filter, clogged drain hose, or drain pump failure
F3
Water Inlet Fault (Overfill)
Inlet solenoid failing to close properly
F4
Flow Meter Fault
Faulty flow meter or failed inlet valve
F5
Water Level Fault
Wash pump seized, foreign object in pump, or inlet valve fault
F6
Temperature Sensor (NTC) Fault
Open circuit in NTC sensor wiring or failed NTC sensor
F7
Over-Temperature Fault
Water exceeding 77°C – stuck heater relay or incorrect supply
F8
Heating Fault
Heater not reaching temperature – element, NTC, or pressure sensor fault
F9
Diverter Valve Fault
Foreign object in diverter or failed diverter valve motor
F1 – Leak Error
The flood switch sits in the base pan precisely for moments like this – when water escapes the wash circuit and starts pooling where it shouldn't. Tripping it locks the wash cycle immediately and keeps the drain pump running, which prevents further accumulation but won't clear the fault on its own.
Start by pulling the machine slightly forward and checking for the leak source: door seals deteriorate over time and are a common culprit, as are loose hose clamps on internal connections and hairline cracks in the wash arm where pressure builds during a cycle. Repair the source, then dry the base pan out fully – a fan or placing the machine in a warm room speeds this up. The switch resets automatically once it stops detecting water.
F2 – Drain Fault
The machine wasn't able to drain within the expected time window. Start by cleaning the filter at the bottom of the tub – food debris is the most common blockage. If the filter is clear, inspect the drain hose for kinks. The drain pump coil can be checked with a multimeter; it should read approximately 141 ohms. Running a hot empty cycle monthly reduces the chances of F2 occurring.
F3 – Water Inlet Fault (Continuous Fill)
Unlike a standard fill fault, F3 indicates the dishwasher is filling with water when it shouldn't be. The inlet solenoid valve isn't closing properly, causing water to keep entering the machine outside of the fill phase. This almost always requires the inlet valve to be replaced.
F4 – Flow Meter Fault
F4 tells you the PCB isn't getting a signal from the flow meter during filling – but it doesn't tell you why. The key diagnostic question is whether water is actually entering the machine when it should be.
Water entering but no flow meter signal: the meter itself has likely failed. No water entering at all: the inlet valve isn't opening, and the flow meter has nothing to measure. Both are replaceable parts, but swapping one without confirming the cause first is an easy way to spend money on the wrong component.
F5 – Water Level Fault
The dishwasher reports no water during the wash phase. This can mean the inlet valve didn't fill correctly, but it can also point to a seized wash pump. Westinghouse's pump design on these models doesn't include a motor tachometer, so the control board can't tell whether the wash pump is running or jammed – a piece of glass can stop the impeller silently. Check whether the machine is filling by listening for the fill valve; if water is going in but F5 still appears, the wash pump needs inspection.
F6 – Temperature Sensor (NTC) Fault
The NTC temperature sensor circuit is open. Start by checking all connector plugs for loose connections. If connections are secure, measure the sensor resistance – at 25°C it should read approximately 47.2 kΩ (±800 Ω). A reading outside that range confirms the sensor needs replacing. If both the sensor and wiring check out, the main PCB is at fault.
F7 – Over-Temperature Fault
The water temperature has exceeded 77°C, or the NTC is reporting that it has. If the machine is correctly connected to cold supply and mains temperature is below 70°C, the sensor is likely giving a false high reading. If the heater relay on the PCB is stuck closed, it will keep heating regardless of actual temperature – a board-level fault.
F8 – Heating Fault
The water hasn't reached target temperature within the allowed time. Work through likely causes in order: clean the filter (restricted circulation reduces heating), measure the heating element (27–31 Ω), measure the NTC sensor (47.2 kΩ at 25°C), and check the pressure sensor for correct operation. If all components are within range, replace the main PCB.
F9 – Diverter Valve Fault
The diverter valve, which directs water between the upper and lower spray arms, has a problem. Check for foreign objects first. If clear, measure motor resistance (should be around 10.5 kΩ ±5%). A reading outside that range means the valve needs replacing.
Frequently Asked Questions
What does F2 mean on a Westinghouse dishwasher?
F2 is a drain fault – the dishwasher couldn't remove water within the required time. Clean the filter at the bottom of the tub first, then check the drain hose for kinks. If those are clear, the drain pump may need testing or replacement.
How do I reset a Westinghouse dishwasher error code?
Turn the dishwasher off at the power point, wait 30 seconds, and turn it back on. If the fault code returns, the underlying issue needs to be fixed.
What causes an F1 error on a Westinghouse dishwasher?
F1 means the flood switch in the base pan has been activated. This indicates a leak – common causes include a deteriorated door seal, a loose hose connection, or a cracked spray arm.
Can I fix a Westinghouse dishwasher error myself?
Codes like F2 and F5 can often be resolved by cleaning the filter and checking the drain hose. Codes involving the PCB, heating element, or inlet valve – F6, F7, F8, and some F4 and F9 cases – typically require a qualified technician.
How often should I clean my Westinghouse dishwasher filter?
At least once a week for daily use. Run an empty hot cycle with a cleaning tablet monthly to prevent F2 drain faults and maintain wash performance.
When to Book a Repair
Codes pointing to the PCB, heating element, NTC sensor, or inlet valve aren't safely diagnosed or repaired without the right test equipment. If your Westinghouse dishwasher is showing a fault code that isn't resolved after a filter clean and hose check, it's time to bring in a professional.
