F09Serious
Amana Washer F09 Error Code
The washer has detected too much water in the tub, or the water level sensor is faulty.
Common causes
- Stuck pressure switch or hose
- Faulty water inlet valve (stuck open)
- Control board error
How to fix it
- Turn off water supply immediately to prevent flooding.
- Check the pressure switch hose for blockages (clear plastic tube from tub to switch).
- Test the inlet valves by unplugging the washer and checking if they close completely.
⚠ When to call a pro: If the water continues to fill with washer off, replace the inlet valve; otherwise call for pressure switch diagnosis.
