Quick answer: An LG dishwasher showing OE — which can read as 0E on some displays — has a drain fault: it could not pump the water out within its time limit. The two most common causes are a clogged filter assembly in the base of the tub and a kinked or badly routed drain hose. Start by twisting out the filter set in the tub floor and rinsing it clean — that alone clears most OE codes. If the filters and hose are clear and OE keeps returning, the drain pump is the usual fix — LG dishwasher drain pumps are around $30 and swap in about 30 minutes.

What the OE code means
At the end of every wash and rinse stage, an LG dishwasher runs its drain pump and expects the tub to empty within a set window. If the level sensor still sees water when the time runs out, the cycle halts and the display shows OE — a drain error. The machine is telling you it tried to pump the water out and could not do it fast enough.
On most models the code is the letter O followed by E, so it is sometimes read as “0E” — same code, same fault, and everything below applies to both. OE is purely about water leaving the machine; if your dishwasher is showing a different code, start with the full LG dishwasher error code guide instead.
The classic giveaway is dirty water pooling in the base of the tub after the cycle ends — and, left a day or two, the smell that comes with it. Slow draining counts too: because OE fires on a timer, a machine that eventually empties but takes too long about it will throw the same code. Slow drain now usually means no drain soon, so it is worth chasing even when the water does clear.
Check these before replacing anything
Switch the dishwasher off at the power point before you start, and keep in mind the water in the tub may still be warm. A couple of towels, a cup for bailing and ten to fifteen minutes cover the whole list.
- Bail out the standing water. Scoop the worst of it out of the tub base with a cup and soak up the rest with a towel. You do not need it bone dry — just low enough to work without a flood.
- Twist out the filter assembly. In the floor of the tub, on most models, sits a cylindrical mesh filter locked into a flat mesh plate. Twist the cylinder anticlockwise, lift both pieces out and rinse them under the tap, working stubborn grease off with a soft brush. Rice, seeds, glass chips and jar-label paper are the usual culprits — they form a mat that the water simply cannot get through.
- Check the sump opening. Shine a torch into the well the filter came out of and pick out anything left behind — broken glass hides here, so feel carefully or wear a glove. Debris that gets past a worn filter ends up wedged at the pump inlet, which is exactly where you do not want it.
- Trace the drain hose. Pull the machine forward if you can and follow the hose from the back of the cabinet to the sink waste connection. Straighten any kinks and look for spots where it is crushed against the cupboard. Routing matters as much as kinks: on most installs the hose should rise in a high loop under the bench before dropping to the connection — a hose that has slipped off its clip and sags, or one pushed a long way down a standpipe, can beat the pump on every cycle. If you suspect the sink end, pour a jug of water down the connection point: if it backs up, the blockage is in the household plumbing, not the dishwasher.
- Clean the air gap, where one is fitted. Some installations have a small chrome cylinder at the back of the sink that the drain hose passes through. Pull the cap off, lift out the inner cover and rinse away any build-up — a blocked air gap produces a textbook OE.
- Refit and test. Lock the filter assembly back in, push the machine home without re-kinking the hose, and run the shortest cycle. Listen at the end for the pump running and a steady gurgle at the sink — that is the sound of a healthy drain.
A clogged filter assembly is behind most OE codes, so there is a good chance the machine is already fixed by step two.
The parts that actually fix a persistent OE
If the filters are clean, the sump is clear and the hose runs fair, but OE keeps returning, the drain pump is the next suspect. On most LG dishwashers this is a compact brushless (BLDC) motor mounted at the sump under the tub, and it is a wear item: years of hot water, grit and the odd glass chip take a toll. A failing pump may hum or buzz without moving water, drain at half speed, become noticeably noisy, or go completely silent. Pumps differ between model series, so match the part to your machine before ordering.

On most models the pump twists or screws onto the sump housing at the bottom of the machine and connects with a single push-fit plug, reached by removing the kick panel or laying the machine gently on its back — an achievable DIY swap for a confident home handyperson. Pump designs vary between series, though, so confirm the part against your exact model number first.
Find the exact part for your model
The model number is printed on the model sticker — on the edge or side of the door on most LG dishwashers, visible as soon as you open it. The guide to finding your LG model number walks through every location. From there, enter the number on the Find Your Model page, or take the Part Finder quiz and let it match the right drain pump to your machine in a couple of minutes.

FAQ
Is OE the same as 0E?
Yes — it is the same code read two ways. The display shows the letter O followed by E, which is easy to read as a zero. On most models both point to the same drain fault, and the checks are identical: filter assembly first, drain hose second, pump last.
There is always a little water in the filter well — is that normal?
Yes, on most models a small amount of water sits in the sump between cycles to keep the pump seals from drying out. OE is about the tub itself failing to empty — a puddle across the whole tub floor is a problem; a cupful down in the filter well is by design.
I cleaned everything and OE went away, but it comes back every few weeks — why?
A recurring OE usually means debris is rebuilding faster than the machine can cope with, or the pump is losing strength. Scrape plates before loading, skip the jar labels and rinse the filter assembly monthly. If the habit is already clean and the code still returns, a pump that drains slower each time is the likely cause — replace it before it stops altogether.
How do I clear the OE code once the blockage is fixed?
Switch the machine off at the power point for a minute or two, switch it back on and run a short cycle. On most models the code clears itself as soon as the machine completes a drain within its time window — there is no hidden reset sequence to hunt for.
Where is the model number on an LG dishwasher?
On the model sticker on the edge of the door or the side of the door frame — visible when the door is open. Use the full model number when matching a pump, because the LD-series families use different connector and mounting variants of the same pump platform: the LG model number guide shows exactly where to look.
