Kathy spotted a leak under the dishwasher. (KitchenAid KUDL02FRSS0.) I shut off the fuse, disconnected the power (because the electrical cable is too short to pull the washer all the way out) and removed the white sound blanket. There was water under the washer, but I could not see the source. There was a silver metal jacket inlet hose from the sink and a yellowish plastic drain hose, but neither were wet. The tub itself did not seem to have any leaks. It was a mystery.
