Quick answer: An LG washing machine showing FE has detected overfilling — the water level climbed past what the cycle asked for. The two most common causes are a water inlet valve that no longer closes fully, letting water seep in even when the machine is not calling for it, and too much (or the wrong) detergent pushing a cloud of suds past the level sensor. First check: turn both taps off at the wall — if the rising water stops immediately, the valve is stuck open. Cut back the detergent dose before blaming any part.

What the FE code means
Your washer meters every fill with a pressure sensor: as water rises in the tub it compresses air in a small hose, and the sensor turns that pressure into a level reading. The control board opens the inlet valve, watches the level climb to the target and shuts the valve again. FE means the level kept climbing past the overfill mark — water was getting in when the machine was not asking for it. On most models the machine responds by running the drain pump on its own to dump the excess; that is the overfill protection doing its job, not a second fault.
FE is the mirror image of a fill-timeout fault, and different again from a drain fault — a machine that cannot pump water out shows OE instead, covered in the LG OE error code guide. If your display is showing something else entirely, start at the full LG washing machine error code guide. FE itself almost always comes down to one of three things: a valve that will not seal, suds fooling the sensor, or — less often — the pressure sensor misreading.
Check these before replacing anything
Switch the machine off at the power point, and know where your laundry taps are before you start — they are your main diagnostic tool here.
- Turn both taps off the moment FE appears. Watch the water in the drum. If it stops rising as soon as the taps close, the supply side is your culprit — and on most models that means the inlet valve is letting water past when it should be sealed shut.
- Do the overnight test. Leave the taps on, the machine off and the drum empty overnight. Water pooled in the drum by morning is the classic sign of a valve that no longer seals — a slow seep is all it takes to overfill a cycle that expected a precise level.
- Check your detergent. Front loaders need a low-suds detergent, and even the right detergent overdosed will whip up foam that lifts the level reading. If FE arrived with a new detergent or a generous pour, run a rinse cycle with an empty drum to clear the foam, then dose to the minimum mark for the next few loads.
- Do a 10-minute power reset. Switch off at the power point for ten minutes so the control board restarts from scratch, then open the taps, run a small load and watch the first fill — the level should stop climbing well below the door glass on most models.
The parts that actually fix a persistent FE
The water inlet valve is an electrically operated tap: the control board energises a solenoid to open it, and a rubber seat holds it sealed the rest of the time. A speck of grit from the mains or a worn seat is all it takes for the valve to weep continuously — too slowly to notice during a normal fill, fast enough to push a cycle past its overfill mark or fill an idle drum overnight. LG uses different valve layouts across its ranges — 2-way and 3-way, front loader and top loader — so match the valve to your series. The LG WV series parts guide and the WTG / WTS top loader parts guide map the two big families.
| Symptom pattern | Likely part | Link |
|---|---|---|
 Drum slowly fills while the machine is off, or FE early in the cycle — WV5-1275W / WV5-1408W / WV5-1409W / WV5-1410W | 2-way inlet valve | LG washing machine 2-way inlet valve (WV5 series) |
 Overfilling on FH069FD2MS / FH069FD3MS / FH0C7FD3MS front loaders | 3-way inlet valve | LG washing machine 3-way inlet valve (FH069FD2MS / FH069FD3MS / FH0C7FD3MS) |
 Overfilling on WD1402CRD6 / WD14030RD / WD14030RD6 front loaders | 3-way cold water inlet valve | LG washing machine 3-way cold water inlet valve (WD1402CRD6 / WD14030RD / WD14030RD6) |

One honest caveat: a minority of FE faults are not real overfills at all — the pressure sensor or its air hose misreads, and the board reacts to a level that is not there. If the overnight test is bone dry, the detergent dose is sensible and a sound valve still throws FE, the pressure sensor is the next suspect. Sensors vary widely between models, so run your machine through the Part Finder quiz rather than guessing — it will route you to the right sensor or valve for your exact machine.
Find the exact part for your model
Your model number is on the model sticker — around the door opening on most front loaders, and on the back panel or under the lid on most top loaders. The guide to finding your LG model number shows exactly where to look for each machine type. Once you have the number, drop it into the Find Your Model page and it will narrow the catalogue to the valves and sensors that fit your machine — or the Part Finder quiz above gets you to the same place by answering a few questions.
FAQ
Why does my LG washer fill with water when it’s switched off?
Because the inlet valve is held shut by a spring and a rubber seal, not by electronics — switching the machine off does not close a valve that can no longer seal. Water seeping into an idle drum is the classic stuck-open valve symptom, and it is the same root cause behind most FE codes. Keep the taps off at the wall until the new valve goes in.
Can too much detergent really cause an FE code?
Yes. The pressure sensor cannot tell dense foam from water, so a big suds cloud reads as a higher level than is really there — on most models that is enough to trip the overfill mark. Run an empty rinse cycle to clear the foam, switch to a low-suds detergent if you are not already on one, and dose to the minimum mark.
Is FE the same as IE or OE?
No — they are neighbours on the same water circuit. IE means the machine could not fill in time (too little water), FE means it filled past the limit (too much), and OE means it could not drain. The OE guide linked above covers the drain side; FE work is all on the fill side — taps, valve, suds and sensor.
Should I replace the inlet valve or the pressure sensor first?
The valve, in almost all cases — and let the overnight test decide for you. Water in an idle drum by morning proves the valve is passing, and no sensor will fix that. If the overnight test is dry and the detergent dose is right, a persistent FE points at the pressure sensor instead — confirm the exact sensor for your model before ordering anything.
