Hello, Can you tell me what code F7E9 is referring to? I have a whirlpool front loading washer model number WFW75HEFW0. The motor/drum turns freely by hand but when plugged in the motor/stator assembly makes a constant humming sound and does not turn. I checked the continuity of all three motor connector pins and all read about 13 ohms (manual says 5 -20 is ok). The motor and stator appear in perfect condition. Is this a problem with the ACU board? Thanks for your help.
