How to fix Whirlpool Duet F20 Error:
Whirlpool uses a flow meter that detects the flow of water entering the washer. If this flow meter does not detect the correct amount of water entering the washer it will sound the F20 error code. Often this repair can be made with out calling an appliance repairman and without ordering parts. Start by removing the washer fill hoses; both the cold and the hot water hoses. Check for proper water pressure
from the house. To do so, turn the water on and put the hose inside the washer or a bucket.
If water pressure is good, check the water valve inlet screens. Most residential washing machines have inlet screens. The screens prevent minerals from clogging the solenoid. With the hoses removed, you can visually inspect the water inlet screens. If the water valve screens are clear the inlet valve with the screens itself will need to be replaced. To replace the water valve, remove the top of the washing machine. Three screws
hold the top down. The screws that hold the top down are on the back of the top panel. Once removed the top will slide back and off. Now remove the wire harness that connects to the valve. One screw holds the valve to the washers cabinet. Removing the screw and sliding the valve over will release the valve from the back panel enabling you to complete your repair.
