FE on an LG washer means “fill error” — specifically, the machine is overfilling with water. This is urgent. An FE error means water is still entering the drum past the fill limit and could overflow. Stop the machine and turn off the supply valves immediately.
What This Error Means
The fill cycle should stop when the water level sensor signals that the tub is full. FE appears when the water keeps rising past that point — because the inlet valve is stuck open and won’t close, or the water level sensor is giving a wrong reading that tells the machine to keep filling.
Common Causes
- Stuck-open inlet valve — The most common cause. The solenoid valve that admits water fails in the open position. Water flows continuously even when the machine tells it to stop.
- Failed water level pressure sensor — The sensor that tells the board the tub is full is sending the wrong signal, causing the machine to keep filling.
- Pressure hose issue — A disconnected or clogged pressure hose gives a false empty reading, causing overfilling.
Step-by-Step Fix
-
Stop the machine and unplug it immediately. If water is running out of the machine, turn off the supply valves behind it immediately — a stuck-open inlet valve will continue to fill the machine even with power off until you close the supply valves.
-
Check the pressure hose first. Remove the top panel and inspect the thin hose running from the drum to the pressure sensor. If it’s disconnected, the sensor reads “empty” and the machine keeps filling. Reconnect firmly.
-
Test the inlet valve. Once safe to do so, partially reopen the supply valves and start a fill cycle. Watch the inlet valve area through the back panel access. The valve should close after the tub fills. If water keeps flowing after the tub is full, the inlet valve is stuck open and must be replaced.
-
Replace the inlet valve. This is the fix for true FE — a failed valve that won’t close. Access from the back panel, disconnect the water hoses and electrical connectors, and swap the valve.

When to Call a Technician
FE is worth taking seriously — a stuck-open valve can cause significant water damage if the machine is left unattended. If you’re not comfortable accessing the back panel to replace the inlet valve, call a technician promptly.
