What does LG Washer FE Error Code - Causes & Fix mean?

FE means your LG washer is overfilling. The water inlet valve is usually stuck open or leaking. Turn off water and replace the valve.

How do I fix LG Washer FE Error Code - Causes & Fix?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Can I keep running the equipment with this fault active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

What part is most commonly replaced for LG Washer FE Error Code - Causes & Fix?

The most frequently replaced parts for LG Washer FE Error Code - Causes & Fix are listed in the Parts Reference section of this guide with OEM part numbers and typical price ranges. Check the table for direct replacements.

Is LG Washer FE Error Code - Causes & Fix a DIY repair or do I need a technician?

Sensor swaps, fan motor replacements, and condenser cleaning are typical DIY-level repairs. Anything involving refrigerant, gas, or high-voltage (>240V) work requires a licensed technician for both safety and code-compliance reasons.

LG Washer FE Error Code - Causes & Fix

LG Washer FE Error Code — What It Means

The FE error code on an LG washer indicates an overfill condition. The washer’s control system has detected that the water level in the tub is higher than it should be for the selected cycle and load size. LG describes this as a fill error tied to excessive water in the drum.

This code usually means water is still entering the tub when it should have stopped, or the machine is incorrectly reading the water level. The most common hardware fault is a water inlet valve that will not close completely, allowing water to seep or flow in continuously even when the valve coils are not energized.

Common Causes

Stuck-open or leaking inlet valve The water inlet valve fails to seal properly when de-energized, allowing water to continue entering the tub and triggering the overfill condition.
Debris or sediment in inlet valve or screens Buildup in the inlet valve body or on the hose screens prevents the valve from closing fully or disturbs the normal fill cycle.
Faulty pressure switch or pressure sensor The sensor that monitors tub water level gives false readings to the control board, causing the machine to think the tub is overfilled even when it is not.
Wiring or connector problems Damaged wires, corroded terminals, or loose connectors between the inlet valve, pressure sensor, and control board create false signals or intermittent valve operation.
Clogged drain pump filter A blocked filter prevents proper drainage and can confuse the water-management system, contributing to high water levels or error detection.
Control board failure In rare cases the main control board itself malfunctions and misreads water-level signals or fails to command the valve correctly.

Step-by-Step Fix

Turn off the water supply valves at the wall behind the washer immediately to prevent continued filling.
Unplug the washer from power and wait one minute, then plug it back in to reset the control board and clear any transient fault.
Drain any excess water by selecting a drain-only or spin-only cycle, or manually drain using the drain hose if the tub is overfull.
Inspect and clean the inlet hose screens by removing both hot and cold hoses from the back of the washer and checking the small mesh filters in each inlet port for sediment or debris.
Check for water seeping into the tub when the washer is off by opening the door and watching the drum for several minutes with water valves on but machine unplugged; any dripping indicates a valve that will not close.
Test the inlet valve by accessing it (usually behind the top or rear panel), disconnecting the wiring, and using a multimeter to check coil continuity and inspecting the valve body for cracks, corrosion, or stuck seats; replace the valve if it leaks or fails electrical checks.
Inspect the pressure sensor, air tube, and wiring if the valve tests good; look for kinked or disconnected tubing, water or debris in the air chamber, and continuity faults in sensor wiring; clean or replace components as needed.
Clean the drain pump filter at the lower front of the washer to rule out drainage restriction as a contributing factor.
Run a test cycle after repairs to confirm the FE code does not return and water levels remain normal throughout the wash.

Parts Often Needed

Part	Notes
Water inlet valve assembly	Amazon \| Primary replacement for overfill faults; confirm your model number and valve connector type before ordering.
Pressure switch or pressure sensor	Amazon \| Replace if sensor gives false water-level readings or shows open or shorted continuity.
Inlet hose screens or inlet hoses	Amazon \| Replace if screens are damaged or hoses are kinked, split, or heavily clogged.

When to Call a Pro

Call a qualified appliance technician if you are not comfortable working with water connections, electrical testing, or removing panels. If you have replaced the inlet valve and cleaned all filters but the FE code returns, the pressure sensor, wiring harness, or control board may be at fault and will require diagnostic tools and model-specific service documentation. LG recommends professional service when basic user checks do not resolve the overfill error.
