Whirlpool Duet Fills W/ H2O When Off

My Whirlpool Duet washer tub fills with water when the machine is off. I assume the issue is that the inlet control valve is leaking and needs replacing; is that correct?

I have exactly same problem. Did you find out what went wrong and fix the dishwasher?

After long research, I found it could be one of these three:

  1. Control board - this will be expensive part.
  2. Inlet valve
  3. Floating switch

In order to find out which went wrong I will get multimeter for test. Hopefully it is not control board…
