What does the FE error code mean?

The FE in your LG washer stands for “Fill Error.” This code appears when the washing machine detects that it is filling with too much water—more than what’s expected for the selected cycle. To prevent flooding or damage, the washer automatically stops and shows this error.

LG washing machines use a pressure sensor to monitor water levels. If the water goes beyond the safe threshold, the washer triggers the FE error and may attempt to drain the excess.

Common causes of the FE error

Here are the most likely reasons your LG washing machine is overfilling:

• Too much detergent: Oversudsing from using too much or the wrong type of detergent can confuse the water level sensor.
• Faulty pressure sensor: A bad pressure switch may fail to accurately detect water levels, causing overfilling.
• Blocked air chamber: If the air tube connected to the pressure sensor is clogged or kinked, the washer may misread the water level.
• Water level sensor failure: A defective sensor may send incorrect signals to the control board.
• Electrical or control board problems: Damaged wiring or a faulty control board can also result in washer fill errors.

How to fix the FE error (step-by-step)

Try these steps to fix the FE error before calling a technician:

Step 1: Cancel the Cycle and Unplug the Washer

Turn off the machine and unplug it. If water is inside, drain it manually or run a drain/spin cycle to remove excess water.

Step 2: Run a Short Cycle With No Detergent

Plug the machine back in and run a quick cycle without adding detergent. This helps clear out any excess suds that may be affecting the pressure sensor.

Step 3: Check Your Detergent

• Only use HE (high-efficiency) detergent
• Follow the dosing instructions based on your load size
• Avoid using too much soap—excess suds = water level confusion

Step 4: If the Error Returns, Call a Technician

A professional should inspect:

• The air chamber and pressure hose for blockages or damage
• The water level sensor for proper function
• The control board and wiring for electrical faults

They can test and replace faulty components safely and accurately.

When to call a technician

Contact a certified repair technician if:

• The washer keeps overfilling after multiple resets
• The tub fills when the machine is off (may signal a stuck water inlet valve)
• You see multiple error codes or the machine is stuck in a cycle
• There are signs of leaks, electrical issues, or strange smells

A trained tech can determine if there’s a deeper issue with the pressure switch, water level sensor, or main board.

Conclusion

The LG washer FE error points to an overfilling problem—often caused by detergent misuse or a faulty sensor. Many cases can be resolved by reducing detergent or resetting the washer. However, if the error persists, calling a professional can prevent flooding and ensure safe, long-term appliance use.

Don’t ignore an FE error—acting early protects your washer, your floors, and your peace of mind.
