FE Code on LG Washer: Overfilling and How to Stop It

Quick Answer

The FE code on an LG washer means the machine is detecting an overflow condition. I usually find that a faulty water inlet valve is stuck open, allowing water to enter even when the power is off, or the pressure switch hose is clogged with gunk.

Honestly, when I show up to an FE call, it's the inlet valve 80% of the time. The scary part is that a stuck-open valve keeps pumping water in even when the washer's off, and if nobody's watching, you've got an inch of water on your laundry room floor fast. Don't ignore this one. It can go from annoying to seriously expensive damage real quick.

What Does the FE Code Mean?

OK so here's the deal. Your pressure switch watches the water level constantly, and when it hits 'too full,' the control board should close that inlet valve right away. When the solenoid's gunked up with mineral deposits or worn out, it doesn't close and water just keeps coming. Hard water areas are way more prone to this. I've replaced a ton of these valves over the years. Honestly one of the more common overflow codes I deal with.

Symptoms You May Notice

FE flashing on the display while you can actually hear water still trickling into the drum even though the wash cycle stopped
You open the door and the water level is at or above the door boot seal, sometimes already dripping out onto the floor in front of the machine
The drum keeps slowly filling even with the washer completely powered off and cord unplugged, which means your wall supply valve itself is failing, not anything inside the washer
A faint gurgling or dripping sound from inside the machine when it's supposed to be idle between cycles

Can you reset a Lg washer to clear the FE code?

Unplug the washer completely from the wall outlet. Wait a full 5 minutes so the capacitors on the control board can drain down. While it's unplugged, press and hold Start/Pause for 5 seconds. Plug back in. If FE comes right back during the first fill cycle, you've still got a hardware failure somewhere and the reset didn't actually fix anything. Time to work through the diagnostic steps.

Tools Required for Diagnosis

Digital multimeter with resistance/ohms settingPhillips #2 screwdriverSlip-joint or channel-lock pliersTowels or a small bucket for water spillageFlashlight

Service / Diagnostic Mode

With the washer off, press and hold the Spin Speed and Soil Level buttons simultaneously, then press the Power button. The buzzer will sound twice. Press the Start/Pause button repeatedly to cycle through various component tests including the water valves.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

What does FE mean on an LG washer?

FE stands for Fill Error, basically an overflow condition. It means the water level sensor caught the water above the safe fill point. The most common cause is an inlet valve that's stuck open, letting water keep running into the drum even after the fill cycle's supposed to be done. Usually it's sediment on the valve seat or a dead solenoid coil. I replaced three of these on LG front loaders just last week alone in my area.

Is FE dangerous? Can it flood my laundry room?

Yeah, it can. A stuck-open inlet valve doesn't know when to stop, and once the drum overflows, water goes right out through the door seal and onto your floor. I've walked into laundry rooms with a half inch of standing water because someone left the machine running with FE active and went upstairs. Always shut off the supply valves behind the washer the second you see this code, then figure out what's wrong. Don't leave it unattended.

How do I test the water inlet valve?

Kill the power and close the supply valves first. Pull the top panel off, two screws at the back. The inlet valve's right where your hoses connect. Pull the wiring harness connectors off each solenoid and set your multimeter to resistance. Touch the probes to the two terminals on each coil. You want 200-500 ohms on both. If either one reads OL, that solenoid's gone and you need a new valve. The swap takes about 20-30 minutes once you've done it before.

Can low water pressure cause FE?

Rarely. Low pressure usually causes long fill errors or timed-out fill codes, not overflow. FE almost always means too much water is getting in, not too little. That said, a sudden pressure surge, like when city workers flush a fire hydrant on your street or a pipe bursts nearby, can slam the inlet valve hard enough to damage the seat and it starts sticking open. So indirectly, a pressure event can trigger FE even though normal low pressure won't.

How much does it usually cost to fix an LG washer FE error?

Depends on what's actually broken. If it's the inlet valve, the part runs about 30-60 bucks and it's honestly not a bad DIY job, maybe an hour of your time. Pressure switch is 15-30 dollars, also pretty approachable. Where it gets expensive is if the control board's stuck energizing the valve, and those run 150-300 bucks or more. In my experience most FE calls end up being the inlet valve, so that's where I'd start. Total out of pocket for most people is under 100 bucks if you do it yourself.
