LG Washer FE Error Code: Overfill Fix & Water Inlet Valve (#5220FR2075L)
Quick Answer: The FE (Flood / Fill Error) code on an LG washing machine means the drum has overfilled with water above the safety limit and the drain pump has turned on automatically. It is caused by a stuck-open Water Inlet Valve (#5220FR2075L) that continues pouring water even when electricity is off.
⚠️ The 5-Second Unplug Test for FE: When your LG washer shows FE, pull the electrical power plug out of the wall! If you STILL hear water hissing and entering the drum with the power cord unplugged, the rubber diaphragm inside your Water Inlet Valve (#5220FR2075L) is physically torn open!

Step 1: Free 2-Minute Reset & Test
- Immediately turn OFF both water faucets behind the washing machine to stop the drum from overflowing.
- Unplug the washer from the electrical outlet: if water stops flowing only when the faucet is closed, your Water Inlet Valve (#5220FR2075L) is mechanically stuck open and must be replaced.
- If the drum is actually empty of water when FE flashes, excessive detergent suds have entered the air pressure tube—run a Tub Clean cycle with 2 tablespoons of cooking oil to dissolve the foam.

Frequently Asked Questions
Can too much laundry detergent cause an FE error on an LG washer?
Yes! If you use non-HE detergent, thick foam rises up the side air chamber tube and pushes against the Water Level Pressure Switch (#6501EA1001R), tricking the washer into thinking it is overflowing with water.
