Whirlpool Duet Washer F20 Error

Troubleshooting and Repair - F20 Error Code - WFW9200SQ00

The F20 error means the main control has killed the cycle because there was no water detected entering the machine. The pressure switch is what determines when the machine has enough water in it, if the pressure switch was not tripped within a 6 minute time frame the control kills the cycle. It does this as a safety precaution in case the pressure switch is bad and it's not shutting water supply off to the washer which would could flood your home. Unplug the washer and follow the troubleshooting steps below.

Verify your water is on and that there is water pressure being supplied to the washer. Remove the water supply lines from the washer and check that the screens on the water inlet valve and water supply lines are not stopped up and are clean. If they looked corroded or stopped up clean them and this will probably fix the problem. 

Make sure the washer is not constantly draining water while its filling due to a vapor lock on the drain on your home. Make sure there is small gap between the drain hose and the drain to ensure the drain can breathe. 

Check the connections and wiring between the water inlet valve, pressure switch, flow meter and the central control unit.

Blow air through the flow meter while checking resistance, make sure its a closed circuit when doing so.

The parts you may need to fix this F20 error are the water inlet valve, flow meter and the water level pressure switch. These Whirlpool Duet Washer parts can be ordered from the link below. The links also provide instructions to change the parts.

Blow Meter

"Unplug the washer and blow into the flow meter and check if it has continuity when you blow through it, if so it's good if not it's bad." Regarding this answer, I'm not sure what is meant by contnuity. Do you mean that I should be able to blow through? And if I can blow through that means its working? And if I blow through and it is stopped that means it needs to be replaced? Thank you!

Unplug the flow meter from the wiring. Connect your ohmmeter leads to the flow meter terminals and blow through it. If the flow meter has an open circuit while blowing through it it's bad. If you don't understand that then you need to watch one or more of the videos linked below:

F20 Error Code

WFW9200SQ00 from 2006/2007 How do I determine if my problem part is the flow meter or the pressure sensor? I've gotten this code in the past and cleaned the inlet hoses and screens and the problem went away. This time it didn't. Is there a way to jumper one or both sensors to see if the problem goes away? I seem to get decent flow from both hot and cold water individually. When I start a Hot water cycle, I don't get the error once the water is hot. When I start a warm or cold water cycle, I do get the error code. Thank you, Steven M

Unplug the washer and blow into the flow meter and check if it has continuity when you blow through it, if so it's good if not it's bad.
