Error Code FE
The FE error code means water continues flowing into the tub after it should have stopped. The water level pressure switch detects the tub is overfilled and triggers the error. The washer activates the drain pump to prevent flooding. A stuck-open water inlet valve is the primary cause. This error requires immediate attention to prevent water damage.
Common Causes
Stuck-open water inlet valve: The solenoid inside the water inlet valve is seized in the open position. Water flows continuously regardless of what the control board commands. Mineral buildup or a mechanical failure in the valve plunger causes this.
Faulty main control board: The main control board sends a constant fill signal to the inlet valve even when the tub is full. A failed relay or burned component on the board is the cause.
Defective water level pressure switch: The pressure switch sends incorrect readings to the control board, making it think the tub is empty when it is full. The board keeps the valve open because it believes more water is needed.
Clogged or disconnected pressure hose: The small rubber hose connecting the tub to the pressure switch is kinked, clogged, or has fallen off its barb. The switch cannot read water level accurately.
DIY Troubleshooting
Stop the water immediately: Turn off both hot and cold water supply valves behind the washer. Unplug the washer from the wall. If the tub is overflowing, place towels around the base and use the emergency drain hose at the bottom-front panel to drain water into a bucket.
Test the inlet valve for mechanical failure: With the washer unplugged and supply valves off, disconnect the fill hoses from the back of the washer. Turn the supply valves back on briefly and check whether water drips from the inlet valve ports on the washer. Water coming from the valve with no power to the machine confirms the valve is stuck open and needs replacement.
Inspect the pressure hose: Remove the top panel of the washer (screws at the rear). Locate the small rubber tube running from the outer tub to the pressure switch. Make sure it is firmly connected at both ends and has no cracks, kinks, or water inside it. Blow gently through the hose — you should hear a click from the pressure switch. No click means the switch or hose is faulty.
Check the pressure switch: With the hose connected, use a multimeter to test the pressure switch terminals for continuity. The switch should toggle between open and closed as you blow into the hose. If the switch does not toggle, replace it.
Replace the water inlet valve: If the valve is stuck open, order the correct replacement for your model. Unplug the washer, turn off supply valves, disconnect fill hoses, remove the rear panel screws and two mounting screws holding the valve, disconnect the wire harness, and install the new valve in reverse order. Run a test cycle with the washer pulled out from the wall so you can watch for leaks.
