LG washing machine error code OE

💡

Quick Answer

Check whether water is still inside the drum when OE appears. If the drum is full or partially full of water – a physical drain fault is the cause, start with the pump filter. If the drum appears empty but OE still shows – a pressure system fault may be preventing the machine receiving the “water gone” signal.

⚠️

LG error code OE – drain fault detected

Error code OE on an LG washing machine means the machine has detected that water is not draining correctly within the expected time. The most common causes are a blocked pump filter or a blockage inside the pump impeller. OE can also be triggered by a faulty pump motor, a blocked drain hose, or a pressure system fault that prevents the machine detecting that the water has gone.

What OE Means on an LG Washing Machine

OE stands for an outflow (drain) error. The machine monitors the drainage process and expects the water level to drop within a set time. If that drop is not detected, OE is displayed and the cycle aborts. The code does not identify the specific cause – it indicates the machine cannot confirm the water has gone.

Diagnosing OE: Two Scenarios

❌ Water still in the drum when OE appears

The machine is trying to drain but the water is not clearing. This is a physical drain fault – blockage in the filter, blockage or jam in the pump impeller, a blocked drain hose, or pump motor failure. Work through the drain fault diagnosis below.

Drum appears empty but OE shows

The water has drained but the machine still cannot confirm this and refuses to proceed to spin. This is a pressure system fault – the sensor that tells the machine the drum is empty is not receiving or sending the correct signal. This is a more involved diagnosis – see our guide on pressure system faults.

Checking for a Drain Blockage

  1. Check and clean the pump filter.

    The pump filter on most LG front-loading washing machines is accessible behind a small panel at the front base of the machine. Place towels on the floor, slowly unscrew the filter cap to release residual water, then remove and clean the filter. Check for coins, hairbands, hair grips, small socks, and accumulated lint. See our guide on washing machine pump filters.

  2. Listen for the pump running.

    When the machine attempts to drain, can the pump be heard? A running pump with no drainage suggests a blockage downstream of the pump – in the drain hose or at the standpipe connection. A silent pump suggests the pump motor is not running – either a jammed impeller or a failed motor.

  3. Check the pump impeller through the filter opening.

    With the filter removed, shine a torch into the pump chamber where the impeller is visible. Objects such as glass fragments, coins, or small items can jam the impeller. The impeller should turn freely by hand. If it will not rotate or is broken, the pump needs replacement.

  4. Check the drain hose connection.

    Confirm the drain hose is not kinked, and that the standpipe or U-bend connection is not blocked. A small object or accumulation of lint at the standpipe connection can restrict flow enough to cause OE. This check does not require moving the machine if the drain hose exits at the back and runs to a standpipe under the sink – unscrew the spigot and check inside.

  5. If no blockage is found – consider an engineer.

    If the pump is running, there is no blockage in the filter or drain hose, and the drum is still not emptying, see our guide on no blockage but still not draining. Pump motor failure and pressure system faults are the remaining causes.

LG levelling note

LG documentation states that the machine must be level and that the front cannot be higher than the back or vice versa. Poor levelling can leave a small residual amount of water in the machine but is unlikely to prevent draining entirely. If OE appears and the machine is visibly unlevelled, correct the levelling first and test again before investigating further.


Frequently Asked Questions

What does OE mean on an LG washing machine?

OE is a drain error – the machine has detected that water is not leaving the drum within the expected time. It most commonly indicates a blocked pump filter, a jam in the pump impeller, or a blocked drain hose. It can also be triggered by a pump motor fault or a pressure system fault that prevents the machine detecting the drum is empty.

My LG shows OE but the drum looks empty – what does this mean?

If the water has drained but OE still displays and the machine will not spin, the pressure system is likely at fault. The machine uses a pressure switch to confirm the drum is empty before spinning. If this system is not providing the correct signal – due to a blocked pressure chamber hose, a faulty pressure switch, or a PCB issue – the machine will not proceed to spin even though the drum is actually empty. This requires a more detailed diagnosis, ideally by an engineer.

How do I reset the OE error on an LG washing machine?

Clearing the error code without resolving the underlying fault will cause OE to return immediately on the next cycle. The fault must be identified and resolved first. Once the drain fault is fixed – whether by cleaning the filter, clearing a blockage, or repairing a component – the error should clear on the next successful drain.

Jill 1 reply Thank you! I kept getting the 03 error code. When it was time to drain it made a horrid grind/groan and nothing happened. I unplugged it and waited 10 seconds for a reset, hit power then start. No go. I hit start to pause it, then hit no spin, start, start, low spin, start and went up through the levels while listening. A couple times there was a shift in the grind groan sound and finally it thunked! It now is working like it hasn't in a couple of months. Water spouting out the drain! You gave me the info to figure it out. Hope this makes sense and can help someone.

Thanks Jill, it could have been an obstruction inside the machine which has shifted out of the way. If the fault returns you will need to try and get it out. Hopefully it will be ok now though.

YREVA 0 replies So. the pump was changed and everything seems to be fine with the motor but the water still wont come out...any ideas

Chris 0 replies Great info here. My tub would not drain I have a top loader lg, drained what I could out of the drain hose into a bucket tilted machine forward till water was below tub drain. Removed 4 screw cover on back and took the 2hoses loose from pump, pulled out debris with needle nose pliers hook back up and works great.

Whitegoodshelp (Andy Trigg) 0 replies It's possible one could be designed to just pull forward but most pump filters should come right out. Check it isn't jammed in by a bra wire or something tangled up. There is a small section which mentions dealing with a jammed pump filter in this article pump filter

alison 0 replies I can't get my pump filter off. It loosens & comes out a bit, but not enough to properly clean inside. I poked about and found 10p ! I was just trying to do a maintenance thing, there's no problem. Should the filter come right out??

Neil 0 replies Remove right side cover. There is a clear trap for the drain. Unscrew vent inside dishwasher to remove. Cleaned out food which was blocking one-way valve. Problem solved!

cheryl 0 replies Great! I was getting the OE error code and after reading the advise on here I drained the machine opened the filter and I pulled out a colour catcher cloth!, i didn't know something of that size could be drained out with the water! Thanks.

Bart 0 replies The OE code is a fault saying that the washer is not draining. First clean the filter, then after that; First test is to run the unit and when it gets to the spin cycle, when it stops and no longer does anything, pull the manual drain tube and drain it, when the unit starts to spin again then you know it is the pump! Find replacement pump and install, I purchased mine from Repairclinic.com(I am not affiliated with them, just a DYI'er). When you go to replace the pump, DO NOT remove the large black basin drain tube, you don't have to, just remove the gray drain pipe, it's an easier repair. Once the new drain pump is installed it should work. I just did it and the washing machine works properly. If the pump is not the problem, you have something else going on.

Catherine Robinson 0 replies Thank you for your comment, it crashed completely two weeks ago and then started working intermittenly again mid-week so last weekend I successfully changed both the drain pumps on the washing machine and it is now working perfectly again. (I actually feel quite pround of myself, being as it what we term in our house as a 'blue job'.) Have also switched washing powders after reading your article too. Thanks!

Anonymous 0 replies Thanks. I moved my washer before I read that the panal could be on the front. It's all good now.
