My dishwasher wouldn't turn on the other day when I hit the start button. I figured it was the fill valve, but that has since bench tested to be just fine. I have 120VAC on one side of the fill valve connector when the unit is off. The other side of the connector is at 0VAC. When I hit the start button, I have 120VAC on both sides (referenced to the frame of the dishwasher), but the fill valve won't open. My question is which is more likely - a bad wire that has enough connectivity to give me a voltage reading but opens when current tries to pass or a bad control board?
If you are getting 120 vac to the water valve when the unit is calling for water and no water is coming through then you need to replace the water valve.
