LG Dishwasher Error Codes — Complete Australian Guide (2026)

Quick answer: LG dishwasher error codes are two-letter fault codes on the display, and the first letter points at the system that failed its self-check: IE means the machine cannot fill, OE means it cannot drain, LE is a locked wash motor, HE is a heating fault and AE means the base has detected a leak. The master table below decodes all 12 documented codes — most of the common ones trace back to a blocked hose or filter, a failed inlet valve or a failed drain pump, with same-day dispatch from our Sydney warehouse when a part is needed.

Last updated August 2026

LG dishwashers display 12 distinct documented error codes, from IE to PF. Every one of them has a live card in our free error-code decoder, which covers 292 appliance error-code cards built only from codes documented in our published repair guides.

When an LG dishwasher hits a problem it does not leave you guessing — it stops the cycle, beeps, and puts a two-letter code on the display. That code is the machine telling you exactly which system failed a check: filling, draining, heating, washing or leak detection. Call them error codes or fault codes — it is the same two-letter system, and once you can read it, you skip the guesswork and go straight to the fix.

This guide covers the documented error codes on LG dishwashers sold in Australia, including the LD-148 series, LD-1452/1453/1454 series and the newer TD-C and TD-H QuadWash models. For each code you get the plain-English meaning, the most likely cause in an Australian kitchen, and the part or check that clears it. It completes our dishwasher error-code cluster alongside the Bosch, Fisher & Paykel and Haier guides.

What do LG dishwasher error codes mean?

LG uses a simple pattern: the first letter usually points at the system, and the E stands for error. So IE is an Inlet (fill) error, OE is an Outlet (drain) error, HE is a Heating error, and so on. The dishwasher runs a self-check at each stage of the cycle — if the tub has not filled within a set time, or the water has not drained, or the temperature has not risen the way the control board expects, it stops and shows the matching code.

Two things worth knowing before you start:

1. A code describes a symptom, not always a dead part. IE means “water did not arrive”, which is a failed inlet valve on some machines and simply a kinked hose or a turned-off tap on others. Always do the free checks first.
2. Some codes clear with a reset, some never will. A one-off glitch, a foam overload or a power flicker can throw a code that vanishes after a reset. A genuinely failed pump or valve will throw the same code every cycle until the part is replaced. The reset section below tells you how to sort one from the other.

LG dishwasher error codes — quick-reference table

Only widely documented codes for LG dishwashers sold in Australia are listed here. If your display shows something that is not in this table, note the exact code and your model number and run it through the Part Finder. The decoder column jumps straight to that code’s card in our error-code decoder.

LG dishwasher IE error code — not filling

LG dishwasher code IE means the tub did not fill with water in the expected time. The usual fix is free — open the tap fully and straighten the inlet hose — and if water still cannot enter the machine, a failed inlet valve is the part to replace.

Work through the free checks in order: the tap behind the sink fully open, the inlet hose not kinked where the machine was pushed back, and the small filter screen at the hose connection clear of grit. Restore power and retry — an IE thrown by a nudged tap clears immediately and stays away. If water reaches the machine but never enters the tub, fit the LG dishwasher inlet valve, one of the easier swaps on the machine once power and water are isolated. The step-by-step lives in our LG dishwasher IE error guide, and the IE decoder card gives you the short version.

Three checks for IE, in order:

1. Open the tap behind the sink fully and run it into a jug. A tap nudged closed when something was stored under the sink is the most common IE.
2. Straighten the inlet hose where the machine was pushed back, then unscrew the hose at the tap end and rinse the small mesh screen inside the brass barb.
3. Restore power and start a short cycle. If the tap is on and no water enters the tub in the first minute, the inlet valve is not opening.

The part that usually fixes it: LG dishwasher inlet valve (5L/min) — in stock, ships from Sydney, typically $20–$30. Match the model list on the product page against your model sticker before ordering.

LG dishwasher OE error code — not draining

LG dishwasher code OE means the water did not drain out of the tub. The usual fix is cleaning the filter assembly and drain hose; if the pump stays silent or just hums at the drain stage, replace the drain pump.

Start at the filter assembly in the tub base: twist it out, rinse off the debris, and check the sump beneath it for anything solid. Follow the drain hose for kinks and make sure the sink spigot is clear. Then run a short cycle and listen at the drain stage — a pump that hums without moving water, or says nothing at all, has failed. LG drain pumps are model-specific, so match your model sticker against the model lists in our product titles: we stock BLDC drain pumps for the LD-148 series, the LD-1452 family and the TD QuadWash models. The full walkthrough is in our LG dishwasher OE error guide, with the OE decoder card for the quick version.

Three checks for OE, in order:

1. Twist the filter assembly out of the tub base, rinse it, and clear the sump underneath of glass, pips and grit.
2. Pull the machine forward and check the drain hose for kinks, then make sure the sink spigot the hose connects to is clear.
3. Run a short cycle and listen at the drain stage. A pump that hums without moving water, or stays silent, has failed.

The part that usually fixes it: LG drain pumps are model-specific, so match the model list in the title to your model sticker: LD-1482T4, LD-1482W4, LD-1483T4, LD-1484B4, LD-1484T4, LD-1484W4, LD-1485T4, LD-1486L4 or TD-C801H, TD-H802SJW, TD-H901MW (QuadWash) — all in stock, ships from Sydney, typically $25–$35.

LG dishwasher FE error code — overfilling

LG dishwasher code FE means an overfill — the machine has detected too much water in the tub. The usual fix is turning the tap off and letting the machine drain, then replacing the inlet valve if it keeps letting water through.

FE usually lands on the inlet side: a valve stuck open, or leaking through even when closed, keeps feeding water after the fill stage should have stopped. Faulty water-level sensing can trigger it too. Turn the tap off, let the machine pump down, then watch the tub base with the tap back on and the machine idle. Water slowly creeping back in means the valve is passing and the LG dishwasher inlet valve — the same part that fixes IE — is the repair. If the tub stays dry and FE still returns, the water-level sensing side is at fault: run your model number through the Part Finder quiz rather than guessing. The FE decoder card keeps the summary.

Three checks for FE, in order:

1. Turn the tap off, let the machine pump down, then unplug it for two minutes to clear the code.
2. With the tap back on and the machine idle, watch the tub base for half an hour. Water creeping in on its own means the inlet valve is passing.
3. If the tub stays dry and FE still returns on the next cycle, the fault is on the water-level sensing side, not the valve.

The part that usually fixes it: LG dishwasher inlet valve (5L/min) — the same part that fixes IE — in stock, ships from Sydney, typically $20–$30.

LG dishwasher LE error code — locked motor

LG dishwasher code LE means the wash motor is locked and cannot turn. The usual fix is clearing the sump of debris — glass, pips or bone fragments jam the wash pump — and replacing the pump motor if it still will not spin.

Isolate power first, then remove the filter assembly and feel around the sump and impeller for anything hard. A shard of glass or a stone-fruit pip that slipped past the filter is the classic cause, which is why LE tends to follow big dinners. Clear it, restore power and run a rinse cycle. A motor that still locks with a clean sump has worn bearings and needs replacing — for the LD-1484 series we stock the replacement LG dishwasher pump motor; for other models, the Part Finder quiz matches your model sticker to the right part. The LE decoder card has the summary.

Three checks for LE, in order:

1. Isolate power at the wall, lift out the filter assembly and feel around the sump for glass, stone-fruit pips or bone fragments.
2. Turn the wash impeller by hand. It should move freely; a jammed impeller is the classic LE after a big dinner.
3. Clear anything you find, restore power and run a rinse cycle. LE returning with a clean sump means the motor bearings have worn.

The part that usually fixes it: LG dishwasher pump motor (LD-1484T4, LD-1484W4) — in stock, ships from Sydney, typically $25–$35. For other model families, match your model sticker against the listings in the dishwasher parts range.

LG dishwasher HE error code — heating fault

LG dishwasher code HE means a heater error — the water is not heating, or has overheated. The usual fix starts with a multimeter test of the heater element and its circuit, so confirm the fault before buying anything.

HE is the one common code that does not point at a single stocked part. First rule out a one-off glitch with the reset steps below. If HE returns, the element and its circuit need their resistance checked with power isolated, and heater-circuit work sits at the cautious end of DIY — if a multimeter is not familiar territory, hand this one to a licensed tradie. If the test does confirm a failed element, run your model number through the Part Finder quiz — LG heating elements are model-specific, and matching against your model sticker beats guessing. You can also browse the dishwasher parts store, and the HE decoder card holds the short version.

LG dishwasher AE error code — leak detected

LG dishwasher code AE means the leak sensor has found water in the base pan under the tub. The usual fix starts at the power point — isolate the machine immediately, then trace where the water is coming from before anything else.

Sometimes AE is only overfoaming: the wrong detergent pushes suds over the tub edge and into the base, where the sensor reads them as a leak — the bE advice below applies. A split hose or a perished sump seal is the serious version, and it will keep leaking until it is found. Mop the base pan dry, run a short cycle and watch for the first drip. If the source is not obvious, this is the code where a licensed tradie earns the call-out — water and electricity in one appliance is no place for guesswork. The AE decoder card is here, and if the machine is under warranty, book it through LG Australia’s support centre rather than opening it up.

What do tE, CE, bE, EE, nE and PF mean on an LG dishwasher?

tE — thermistor error. The temperature sensor is reading out of range; it is a sensor fault, not a heating fault. Run your model through the Part Finder quiz for the matching sensor, or open the tE decoder card.

CE — motor communication error. The control board cannot drive the wash motor. Check the connections with power isolated; a genuinely failed motor takes the same LG pump motor fix as LE — see the CE decoder card.

bE — bubble error. Excess suds detected, almost always hand dishwashing liquid or a detergent overdose. No part needed: run a rinse cycle empty, then use dishwasher detergent only — bE decoder card.

EE — EEPROM error. A control board memory fault, often after a power event. Try a full power reset; if it returns, the board needs professional attention from a licensed tradie — EE decoder card.

nE — vane error. On QuadWash models the moving spray vane cannot reach position, usually because something has dropped and jammed it at the rear. Clear the blockage, reload and retry — nE decoder card.

PF — power failure. Not a fault in the machine: the supply was interrupted mid-cycle. Press Start to resume; if it repeats, check the power point and the circuit — PF decoder card.

How to reset an LG dishwasher error code

Codes caused by a one-off event — a power flicker, a foam overload, a hose that got kinked when the machine was pushed back — will clear after a reset and stay away. Codes caused by a failed part will come straight back. That makes the reset your cheapest diagnostic tool.

1. Switch the dishwasher off at the power point and unplug it (or turn off the dedicated circuit for a hard-wired unit). Wait a full two minutes so the control board fully discharges and clears.
2. While it is off, do the free checks for your code: tap fully open, inlet and drain hoses free of kinks, filter assembly in the tub base clean, sink drain spigot clear.
3. Restore power and run a short cycle empty. No dishes, a normal dose of dishwasher detergent only if the cycle needs it.
4. Read the result. If the cycle completes, it was a transient fault — done. If the same code returns at the same point in the cycle, the component behind that code has genuinely failed, and the table above tells you which part to look at.

One LG-specific note: OE and IE between them account for the large majority of LG dishwasher call-outs, and both have generous free checks. Do not buy a pump or a valve until the hoses and filters have been ruled out — our dishwasher not draining guide walks the whole drain path from filter to sink.

Which LG error codes are most common in Australian homes?

OE (drain) is number one by a wide margin. Australian kitchens feed dishwashers a steady diet of rice, pips and glass fragments, and the LG drain path collects them at the filter, the sump and finally the drain pump impeller. Most OE faults are a dirty filter; the persistent ones are a failed drain pump. We keep model-specific LG BLDC drain pumps in stock, and the dedicated OE error guide covers the full diagnosis.

IE (fill) is next. Half of IE faults cost nothing — a tap that got nudged closed, a hose kinked against the cabinetry. The other half is the inlet valve itself, one of the easier swaps on the machine once power and water are isolated.

LE (locked motor) spikes after big dinners. A shard of glass or a stone fruit pip getting past the filter and jamming the wash impeller is the classic cause. Clearing the sump fixes many of them; a motor that locks with a clear sump has worn bearings and needs replacing.

AE (leak) is the one to respect. The machine has found actual water where it should never be — in the base pan under the tub. Sometimes it is just overfoaming, but a split hose or perished seal will keep leaking. Isolate the machine at the power point before investigating, and if the source is not obvious, calling in a licensed tradie is the right move rather than the cautious one.

A safety note before any repair: a dishwasher combines mains voltage and water. Always isolate the machine at the power point — switch off and unplug, do not rely on the machine’s own buttons — and turn off the water tap before removing any panel. Fitting an inlet valve or drain pump is within reach of a competent person; anything involving the heater circuit, the control board or an active leak (AE) is better handed to a licensed tradie, and plenty of tradies will happily fit a part you have already bought, which keeps the cost down. For a machine still under warranty, contact LG Australia before any DIY work.

Frequently asked questions

What does IE mean on my LG dishwasher?

IE is an inlet error: the tub did not fill with water in the expected time. Check the tap is fully open and the inlet hose is not kinked first. If water reaches the machine but never enters the tub, the inlet valve has likely failed — the LG dishwasher inlet valve is in stock with same-day Sydney dispatch.

How do I fix the OE error on an LG dishwasher?

OE means the machine could not drain. Clean the filter assembly in the tub base, check the drain hose for kinks and make sure the sink spigot is clear. If the drain pump hums or stays silent at the drain stage, replace it — we stock model-specific LG drain pumps. Our full LG OE error guide covers the step-by-step.

Can I just reset my LG dishwasher to clear an error code?

Yes — switch it off at the power point, unplug for two minutes, then run a short empty cycle. If the code was caused by a one-off event like a power flicker or foam overload it will stay away. If the same code returns at the same point in the cycle, a component has failed and needs replacing.

What does the LE error mean and is it expensive?

LE means the wash motor is locked and cannot turn — usually a glass shard or pip jammed in the wash impeller, sometimes a worn motor. Clearing the sump costs nothing. If the motor itself has failed, the replacement pump motor for LD-1484 series models costs far less than a new machine.

Is the AE error code serious?

Treat it seriously. AE means the leak sensor has found water in the base pan under the tub. Occasionally it is just overfoaming from the wrong detergent, but a split hose or perished seal will keep leaking. Isolate the dishwasher at the power point immediately, and if you cannot find the source, have a licensed tradie trace it — water and electricity do not mix.

Where do I find the model number on my LG dishwasher?

Open the door and look at the model sticker on the inner door edge or the side of the door — the model number looks like LD-1484T4, LD1452WFEN3 or TD-C801H. Match it against the model lists in our product titles, or enter it in the Part Finder and we will do the matching.

Are LG QuadWash error codes different from the older LD series?

No — Australian-market LG dishwashers use the same two-letter code system across the LD-148 series, the LD-1452/1453/1454 series and the TD-C and TD-H QuadWash models. The one QuadWash-specific entry is nE, the vane error, because only those models have the moving spray vane. Every code in the master table above applies.

My LG dishwasher shows a code that is not in this list. What now?

We only list codes that are widely documented on Australian-market LG dishwashers — model-specific service codes exist beyond these. Note the exact code and your model number from the model sticker, and run it through the Part Finder or browse the dishwasher parts store.

What is the most common LG dishwasher error code?

OE, the drain error. Clean the filter assembly in the tub base and clear the drain hose first; if the pump hums or stays silent at the drain stage, fit a model-matched LG drain pump.

Which part fixes an LG dishwasher OE error?

The drain pump, once the filter, sump and drain hose are clear. LG drain pumps are model-specific and in stock, ships from Sydney, typically $25–$35. Match the model list in the product title to your model sticker.

What does FE mean on an LG dishwasher?

FE means the tub has overfilled. Turn the tap off and let the machine pump down, then watch the tub with the tap back on: water creeping in means the inlet valve is passing and needs replacing. The LG dishwasher inlet valve is in stock, ships from Sydney, typically $20–$30.

What does LE mean on an LG dishwasher?

LE means the wash motor is locked. Isolate power, clear the sump of glass and pips, and turn the impeller by hand. If the motor still locks with a clean sump, the pump motor bearings have worn and the motor needs replacing.
