Whirlpool WFW9400SW00, washing machine. Continious F20 error, replaced water inlet valve P/N 884150, did not help. Tech came and did not fix either.

This is usually the pressure switch. The pressure switch is the part that the black hose attach's to. I would replace that part. Here is a link to a site where you can order the part
