FE

Overfill Error

Severity

High

When a LG Washing Machine shows FE on its display, the internal diagnostic system has flagged a condition known as "Overfill Error". Most repairs for this code are straightforward and can be completed at home.

Owner's Summary

Your LG washer is receiving too much water. Turn off the water tap behind the machine right now and unplug the power. This is the most important first step — it prevents potential flooding of your laundry room.

Symptoms

LG washer filling with too much water, FE displayed, risk of flooding

Common Causes

Water inlet valve stuck open or leaking
Defective pressure sensor not detecting correct water level
Clogged pressure sensor hose giving false empty reading
PCB relay stuck closed

How to Fix

1 Immediately turn off both water supply valves
2 Unplug the machine from power
3 Allow drum to drain through filter emergency hose
4 Inspect and replace water inlet valve
5 Test and replace pressure sensor

Tools You'll Need

Pliers Soft Brush Towels / Bucket Flashlight

Most of these fixes need only basic hand tools. If your repair requires opening electrical housings or testing live components, a multimeter and basic electrical safety knowledge are essential — when in doubt, call a technician.

Technical Explanation

When the drum water level exceeds the maximum safe threshold as detected by the pressure sensor, the LG PCB should de-energize the inlet valve relay immediately. FE indicates this failsafe was triggered — either the sensor detected overflow, or the valve failed to close when commanded.

Is It Safe to Keep Using?

Urgent — active water leak risk. Disconnect water and power immediately before further diagnosis.

Technician's Pro Tip

To test if the inlet valve is leaking: turn off water supply, unplug the machine, and wait 10 minutes. If water continues to trickle into the drum, the valve's internal solenoid seal has failed and the valve must be replaced regardless of electrical test results.
