I have replaced the water valve unit that the hoses attach to and I have replace the pressure switch.

Once I replaced those I unplugged the unit for about 30 seconds and tested the machine and after it fills with water it still stops and flashes the f-20 code.

So I am at a loss at what to do next short of purchasing a new washer.

This unit is maybe 5 years old.

Thank you for any help you guys can provide.

Hi.
Check the pressure switch hose.
Press cancel twice, washer should drain for 3 min.
If the drain pump is OK check the connections at the control board and wire harness.
If everything checks OK - replace the CCU Part number: W10246289

Remember that you can return any unused parts to APP even installed ones.

Post the results.

Simon.
