Possible Causes
Disconnected or split pressure hose, Blocked air dome on tub, Faulty water level pressure sensor, Stuck water inlet valve
How to Fix / Troubleshooting
Safety: Unplug the washer and turn off water supply immediately if overfilling occurs.
- Inspect pressure hose: Remove the top panel and check the small hose from the tub to the water level sensor. Reattach or replace if loose or damaged.
- Clear air dome: Clean the tub air dome connection to ensure air can travel freely.
- Test inlet valve: With power off and water on, see if water continues to flow. If so, the water inlet valve is stuck open and must be replaced.
- Replace sensor: If hoses and valves are fine, replace the water level sensor.
