LG Dishwasher Error Code FE

The FE code on an LG dishwasher stands for a fill error, specifically an overfill condition where water has risen above the normal operating level inside the tub. The dishwasher detects this through its water level monitoring system and automatically activates the drain pump to remove the excess water. The most likely causes are a faulty inlet valve, a damaged control board, or a malfunctioning hall sensor.

No, you should not continue using the dishwasher while the FE error is active. An overfill condition means water is entering the tub beyond its designed capacity, which can lead to water leaking onto the floor or damaging nearby cabinetry and flooring. The drain pump activates automatically to protect the machine, but the underlying cause needs to be corrected before safe operation can resume.

Repair costs vary depending on which component is at fault. A replacement water inlet valve typically costs in the range of $20 to $65 for the part alone, while a hall sensor is generally in a similar range. A replacement control board is the most expensive possibility, often ranging from $100 to $250 or more for the part. Adding professional labor can bring the total repair cost to $150 to $400 depending on the diagnosis and your location.

The recommended first step is to replace the water inlet valve, as it is the most common cause of the overfill condition. If replacing the inlet valve does not resolve the error, the hall sensor and main control board should be tested and replaced as needed. Because the issue involves uncontrolled water entry, it is best to avoid running the dishwasher until the faulty component is identified and replaced.

A reset may temporarily clear the FE code, but the error will return as soon as the dishwasher attempts to fill with water again if the underlying component failure has not been addressed. Resetting does not repair a stuck inlet valve, a faulty hall sensor, or a damaged control board. The reset should only be used after the defective part has been replaced, to confirm the repair was successful.
