Washer-dryer combo overfills with water or shows FE; water may be visible in drum when unit is off.

Safety first: Unplug the unit and turn off both water supply valves immediately to stop filling.

• 1. Stop water flow:
  • Close hot and cold water faucets.
  • Use a wet/dry vacuum or manual draining via the pump filter to remove excess water if needed.
• 2. Check water inlet valve:
  • With water supply off and unit unplugged, disconnect hoses and inspect for debris.
  • If water continues to flow into the tub when the unit is unplugged but water valves are open, the LG inlet valve is stuck open and must be replaced.
• 3. Inspect pressure hose and sensor:
  • Remove the top cover.
  • Locate the small rubber or plastic pressure hose running from the tub/air chamber to the pressure sensor.
  • Ensure the hose is not kinked, cracked, or disconnected.
  • Blow gently through the hose to clear any blockage (do not use high pressure).
  • Check the pressure sensor connection and replace the sensor if FE persists.
• 4. Control board evaluation:
  • If the inlet valve and pressure system are good, the main PCB may be misreading the level signal.
  • Board replacement should be done by a qualified technician.
