LG washer — Error Code FE

The machine has detected a water overflow, typically linked to a malfunctioning water inlet valve.

What it means

When an LG washer displays the FE error code, it signifies a 'Water Overflow Error.' This alert occurs when the pressure switch tells the main control board that the drum contains more water than is safe. To prevent a messy flood in your laundry room, the washer stops the cycle and turns on the drain pump automatically. Often, the pump will keep running until the unit is disconnected from power. Usually, this happens because the water inlet valve assembly has a mechanical failure—specifically, a solenoid diaphragm that gets stuck, allowing water to flow into the tub even when the power is off. Less frequently, this error stems from a broken pressure switch, a clogged air dome hose, or a relay failure on the main control board.

Likely Causes

1

Faulty Water Inlet Valve

This is the most common culprit. If the valve diaphragm fails and locks in the open position, water will keep entering the tub, even if the machine is powered down.
2

Defective Pressure Switch

If this sensor cannot properly interpret air pressure from the dome, it may send incorrect signals to the control board, falsely indicating an overfill.
3

Blocked or Pinched Pressure Hose

Debris buildup or a kink in the clear hose connected to the air dome can prevent the sensor from reading the true water level, leading to an actual overflow.
4

Main Control Board Failure

A relay on the board that has welded shut may continuously provide 120V to the inlet valve solenoids, causing an unstoppable water fill.
5

Excessive Suds

Using standard soap instead of HE detergent, or simply overdosing your soap, can create a mountain of suds that enters the pressure hose and confuses the sensor.

How to clear / reset

To address the FE error, first shut off the hot and cold water taps behind the machine to stop any ongoing filling. Unplug the washer for about 5 minutes to let the control board reset. After plugging it back in, select a 'Spin Only' or 'Drain & Spin' cycle to clear the water from the drum. If the issue was just too many suds, a tub clean cycle might fix it. However, if the water inlet valve is physically stuck, the FE code will reappear as soon as you turn the water back on, meaning you must replace the part.

Common replacement parts

Water Inlet Valve Assembly N/A $45-95

Water Level Pressure Switch N/A $30-70

Main Electronic Control Board N/A $150-300

When to call a pro

If you have turned off the water and reset the unit but the FE code remains, or if the machine keeps filling while unplugged, it is time to call a professional. Diagnosing whether the problem lies with the inlet valve, the sensor, or the control board requires technical skill and a multimeter. A-Fix Service provides a $90 diagnostic fee (which is waived if you proceed with our repair), and we include a 1-year warranty on all parts and labor. We keep common LG sensors and valves in stock to get your laundry back on track quickly.

FAQs

What is the typical repair cost for an LG FE error?

Replacing a pressure switch or inlet valve usually costs between $150 and $250. If the main control board is the issue, costs can go above $300.

Can I perform this repair myself?

If the problem is caused by excess suds, you can resolve it by draining the tub and running a cleaning cycle. Swapping out an inlet valve is doable for experienced DIYers, but troubleshooting the main board is best left to a professional.

Does the FE code reset by itself?

No, it does not. This is a safety feature, so the code will persist until the water is drained and the root cause of the overflow is addressed.

Why is the drain pump running constantly?

When the washer detects an overflow, it activates the drain pump as a safety measure to remove the excess water and protect your floors.

Is it safe to keep using the washer with an FE code?

You cannot run cycles while the FE code is displayed. Trying to bypass this error without fixing the faulty valve could lead to significant water damage in your home and may burn out your drain pump.
