Possible Causes
Foaming from wrong detergent, Blocked pressure sensor, Stuck water inlet valve, Faulty water level sensor
How to Fix / Troubleshooting
Safety: Turn off power and water supply if water is actively rising.
- Check for suds: Open the door. If you see excessive foam, you may have used regular dish soap or too much detergent. Let the foam dissipate, then run a rinse-only cycle with no detergent.
- Clean filter and sump: Remove and clean the filter to ensure proper drainage and level sensing.
- Inspect pressure sensor hose: Access the side panel and verify the small hose to the level sensor is clear and properly attached.
- Replace inlet valve if leaking: If water seeps in even when off, replace the water inlet valve.
