My Whirlpool Duet washer began throwing a F20 error code. According to what I’ve found online, it indicates a water inlet problem. Was looking for advice for what other folks have found to be the cause.
Typical cycle is as follows:
- start a cycle
- washer fills, stops x5
- 4 min in to cycle, the washer is a third full of water, it stops, throws code.
So far, I’ve tried the following:
- unplug / restart
- run multiple cycles (only drain/spin works)
- visual inspection of the inlet screens
- validated that the flow meter spins freely
- replaced water inlet valves
- checked drain and hoses to ensure they were clear
My next step is to replace the pressure sensor switch, which was replaced once before (different error code).
Any ideas?
