LG FE fault codewhat it means and how to fix it
LG publish two different answers for FE. Their manual says close the tap and call an engineer; their UK website says clean the filter and change detergent.
Take care
Does the machine keep filling when no programme is running?
The right answer depends on what you can see. Pick the one that matches.
Choose the option on the left that matches what your appliance is doing, and the answer for that case appears here.
Yes, water comes in on its own
This is the version of FE the owner’s manual describes, and there is nothing an owner can do about it. A valve that will not close is a flooding risk.
Leave the tap off and book it. Do not run the machine to see whether it clears.
No, but there is a lot of foam in the drum
This is the version LG’s website describes, and it is free to fix. Foam reads to the machine as more water than there is.
Run a rinse and spin with no detergent, clean the filter, and reduce the dose next time.
Neither — it just stops and shows the code
The cheap causes on LG’s own list are the filter and the detergent, and both are worth eliminating before a valve is quoted.
Clean the filter, run an empty rinse and spin, then judge.
What FE means
FE is the one code where LG contradict themselves on their own material, and you need both halves to make a sensible decision. The owner’s manual calls it OVERFLOW ERROR, gives the cause as water overfilling due to a faulty water valve, and gives one remedy: close the water tap, unplug the power plug, call for service.
LG’s UK help library publishes a separate article on the same code that reframes it entirely — "Over Flow error", meaning the amount of water in the tub is more than the load requires — and offers a full owner-level remedy instead: clean the drain pump filter, use less detergent, and use a detergent formulated for front-loaders, because liquid and eco detergents foam more than powder. Both are LG-published and neither is a third-party guess. The way to hold the two together is to notice that they describe different situations.
A valve that has stuck open genuinely will overfill a machine, and that is a leak risk in a cabinet full of electronics, which is why the manual reaches for the tap. Foam and a restricted filter can also make the machine read more water than it should, and that is free to fix. So do the manual’s safety step first and the website’s diagnosis second, in that order, and you have followed both.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Too much detergent, or the wrong kind | LG name this on their website version. Liquids and eco detergents foam far more than powder, and foam reads to the machine as water. | Common |
| Drain pump filter restricted | Also from LG’s own article. Water the machine cannot get rid of quickly enough sits above the level it expects. | Common |
| Inlet valve stuck open | The cause the manual names, and the reason it says close the tap. A valve that will not shut fills the machine whether it has been asked to or not. | Occasional |
| Machine or hoses frozen | LG raise thawing in the same article. A frozen drain path stops the machine clearing water it has already taken. | Rare |
What to try yourself
Do the manual’s step first, because it costs nothing and it is the half of LG’s advice that is about safety: close the water tap behind the machine and unplug it at the socket.
If water is visibly above the bottom of the glass, or there is water on the floor, stop here and treat it as a leak. LG’s manual answer for FE is to close the tap, unplug and call for service, and that answer exists for a reason.Think about what went in the drawer. LG specifically name using less detergent and using one formulated for front-loaders, and they say why: liquid and eco detergents foam more. If you have recently changed product or been generous with a liquid, that is the likeliest answer on their own account.
Open the service cover at the bottom front and drain the residual water hose into a shallow tray before you unscrew the filter, which is LG’s own way of avoiding water across the floor. Note that on some models that cover is on the right rather than the left.
Clean the drain pump filter thoroughly and refit it firmly. Run a rinse and spin with an empty drum and no detergent at all, and watch whether the machine now behaves.
If the machine fills on its own with the programme not running, turn the tap off and leave it off. That is the stuck valve the manual describes, and it is the version of FE that needs an engineer rather than a filter.
If the machine has been standing somewhere cold, consider ice before a fault. LG raise thawing on this code, and a frozen drain path clears with warmth and patience rather than parts.
Get a qualified appliance engineer to look at your LG FE
We do not pass enquiries to a repair firm, so there is no form here. When you book a qualified appliance engineer, tell them the make, the model and the exact code or message on the display, and ask whether they carry parts for this make — that is what turns one visit into a repair rather than a quote.
What it costs to fix
Typical repair cost
£0–£170
Time on site
40 minutes
Nothing if it is detergent or the filter. A replacement inlet valve is roughly £90 to £170 fitted, and that is the outcome the manual version of this code is pointing at.

Common questions about LG FE
Which of LG’s two answers should I follow?
Both, in order. Close the tap and unplug as the manual says, because that is the step that protects you if the valve has stuck. Then work through the website version — filter, detergent, an empty rinse and spin — because that is the version that fixes most instances of this code without a bill. The manual is the safety framing and the website is the diagnosis.
Why does LG publish two different meanings?
We can only observe that they do. The printed manual gives OVERFLOW ERROR with a faulty water valve as the cause, and the UK help library gives Over Flow with too much water for the load and a detergent remedy. Both are current LG material on LG hosts. It is the largest single discrepancy in their washing machine documentation.
Does the detergent really matter that much?
LG think so, and they are specific about it: use a detergent formulated for front-loading machines, because liquid and eco detergents foam more. A front-loader tumbles a small volume of water through the wash rather than agitating a full tub, so it needs a low-foaming product. Excess foam is the single commonest cause of a machine misreading its own water level.
Is FE the same as an E12 or an E04?
On LG material outside the UK, yes — their global list gives FE, E04 and E12 as three renderings of one code. We have not found a UK-hosted LG page saying that, so treat it as the likely explanation if your display shows a numeric form rather than as something we can confirm for a UK machine.
