My Kitchen Aid dishwasher model number KUDU02FR that will not fill with water in any cycle including “rinse only”, so I do not think there is a problem with the fill valve. Any suggestions?
Open the door and make sure the float (#15 at the diagram) is in the lowest possible position.
Remove the toe panel and check the float switch (#11) for continuity. Normally it should be closed.
Remove the wires from the water inlet valve and check for 120 VAC between them while the control calls for water.
Post the results.
