KitchenAid KDTM504E Dishwasher Service

Uneven washing is the usual reason someone calls about a KDTM504E, also sold as the KDTM504EPA. The top rack gleams and the bottom is cloudy, or the reverse, and the pump sounds fine.
Water in this machine is sent by a diverter between the arms, so that is where we begin. We run a cycle with racks in place and watch each arm, then free any debris from the arm holes. If water lingers in the tub we work on the pump impeller, and a whining motor gets listened to under load. A latch that fails to register is the final check. We quote the price in writing before ordering any part. We run a full cycle after any repair to confirm both racks come out clean before we leave.
The diverter may favor one arm, or the top arm jets are blocked. We check both and watch the spray pattern. Seeing the spray with racks loaded gives us the clearest picture of what needs repair.
Often. Hum means it has power and is being stopped by a jam. We clear it and test turning by hand. We test rotation and clear the sump before deciding on a replacement, which keeps cost down.
Yes, it points to a latch or switch beginning to fail. A quick test now avoids a no-start later. A marginal latch fails more often over time, and testing it now avoids a surprise no-start later.
