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

  1. Turn off water supply immediately to prevent flooding.
  2. Check the pressure switch hose for blockages (clear plastic tube from tub to switch).
  3. 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.
