F09High
Whirlpool washer error F09
F09 on a Duet is an overflow condition — the pressure switch stayed closed too long, meaning the tub holds more water than it should.

Drain hose plugged or kinked
The 4 free checks
Start at the top. Unplug the machine first.
- 01
Turn off the hot and cold faucets and unplug the machine before anything else — the drain pump keeps running and the door stays locked even if you press Cancel.
- 02
Check the drain hose is not plugged or kinked.
- 03
Check the drain pump for debris and clean it out.
- 04
If the washer is overfilled, check the water inlet valve assembly is shutting off properly.
What causes it
Listed most likely first.
| Cause | How often | DIY |
|---|---|---|
| Drain hose plugged or kinked | Most common | Yes |
| Drain pump failed or clogged with debris | Common | Yes |
| Inlet valve not shutting off properly | Occasional | Call a pro |
| Pressure switch not operating correctly | Occasional | Call a pro |
If none of that fixed it
If the washer was empty instead, the pressure switch has to be tested for accurate operation, and the failed component replaced.
