I recently had a the main PC board fail on this machine and found a replacement. Everything seemed to work but the machine was 'filling' for a very long time. This is because the drain pump is continually running from the start of the cycle and the machine is draining as fast as it is filling so can never reach the required water level. How do i check the water pressure transducer? could this be a faulty PC board?
SOURCE: Washing machine does not drain
does the water pour out when you put the drain hose close to the ground if it does then make sure your pump isnt blocked if it isnt then youll need to replace the pump most pumps have 3 little fins in them if you can stop those fins with a screw driver when pump is going then it deffinatley needs replacing as you cannot fix them sorry for the bad news m8
SOURCE: Frigidaire front load washing machine won't stop filling
it sounds like your water valve is bad or you pressure switch is bad or hose from pressure switch to tub is cloged

what I have found is that the washer thinks it is not pumping out .. if your drain pump is clearly removing the all the water in a good time... then the problem is your pressure switch...it is telling the computer that it still has water in the machine...
replace the pressure switch and it will solve your f21 error.
It is a round unit on the right hand side on top...with a tube and wires going to it...let me know if it helps
SOURCE: Washer continuously fills but drains at the same time during rinse cycle.
you have the drain pipe too low into tthe house drain pipe, raise the washers drain pipe up , you only need four inches down into the hous drain
also the house drain pipe needs to be as high as the lid of the machine before you put the washer drain tube into the house drain
you have a syphoning effect

Unplug the machine. Unscrew the 3 screws under the front edge of the washer. The service technician manual is attached to the panel that slides down and off. Find F21 code. See suggested procedures. Note: My drain pump filter had a baby wash cloth in it along with some change that was disrupting the flow. It is exceptionally easy to remove, clean, and reinstall. Just line up installation notches when reinstalling. Whirlpool should have mentioned this filter in the User & Care Guide, but I could not find it anywhere in there.
