My dishwasher keeps tripping its breaker. I went through the test mode and all components worked until I activated the water valve, which caused the breaker to trip. Not sure how to test the flood switch- I know the valve itself functions by wiring it to 115v on the bench. Could the flood switch be tripping the breaker?
The float switch would most likely not be the issue. The switch can be tested for continuity but the only way that the switch would trip the breaker is if there was moisture that got into the switch. The more likely cause, since the valve passed the bench test, would be that there is a wiring harness issue with the wires for the water valve or a faulty control board relay WD21X10174.
Unit was only draining partial. Checked sump pump motor replaced it with a new one. No clog in the drain hose. Flapper new. Still leaves water in bottom of unit,
You will want to make sure that the drain hose goes up to a 32" loop before going into the drain. If it does not go to the bottom of the countertop first then it will allow water to flow back into the unit. There will be a little bit of water left in the unit but should not be visible unless looking down in the sump.
when the machine is on water comes out of the float is this the switch not moving the float
Answer Jon, Water dripping from the float switch, it usually due to a fill level issue, or detergent "foaming" during the cycle. Several things you want to check: make sure the dishwasher is level in both directions, Remove the float cover WD12X10051 float WD12X10047 and stem WD12X10048 make sure there are no deposits or debris built up on the components, that may cause the float to "stick". Then check the dishwasher for fill, the water level in the front of the tub, should rise to the 1/3 lower portion of the float cover, if the machine id filling properly.
