I have replaced pressure switch, and cpu board, have blown through pressure switch hose and checked it for holes. checked water inlet valve and it has 800 ohms to it. Check filter in bottom of unit...clean. I can not figure out why it will not go any farther than rinse, it give me F20 code. Drain spout is higher than the recommended 30". Any other suggestions?
The washer is sensing that there is not enough or not the correct water pressure is entering the machine. Have you checked the water inlet filter screens on the hot and cold hoses? Sometimes they will clog and therefore the washer will sense a LOW FLOW.
Yes i checked that also. I have sat and watched the machine and it get plenty of water in it.
What is the model number of your Whirlpool washer? Also, AFTER you replaced the Pressure Switch and Main Control Board, did the same exact outcome occur? Did anything change at all? Is the washer on level ground? Did the wiring harness get replaced?
Wfw8300sw05. Yes the exact thing happened. No change. There was no wiring harness with the board. The only other thing i can think of is the computer board behind the control panel.
Have you checked the computer board? Have you checked to be sure there is no faults in the wiring?
I have looked at the board but do not see any burn marks or anything that looks out of place. The harness all look good. No kinks or exposed wires. Not sure how to actually test it.
how do I manually reset the board so that the F20 code will go away and see if it will work that way?
Take off the tube from your pressure switch and blow air through the hose. It is probably clogged up and making the pressure switch push the f20 error code.
We see that you have done that but check once again as there may be something there. Check tube connections also and be sure it is attached and clean.
