Is it possible to wrongly install the shaft seal and drain impeller washer on a dishwasher so that they are too tight and thus cause the motor to strain or lockup ?
I'm not talking about the necessary clearance so the impeller itself does not drag within its housing.
How does the shaft seal work, mechanically? Does the shaft spin around the metal collar in the shaft seal, or does the face of the graphite ring on top spin against the bottom face of the impeller washer??
I can see that the face of the graphite ring on top needs to press tightly against the corresponding face of the impeller washer to prevent a leak.
