867762952 Kenmore Furnace - Instructions

removed spray head, pulled motor/pump assembly. took apart impeller housing and then removed motor and pulled impeller off its shaft, the most difficult part was actually pulling off impeller from the splined shaft. I actually broke old impeller in the process. The good thing is that the new seal came assembled with new impeller so that was not a problem. After re-assembling everything it worked fine and still works for a week since repair.

Disassembled my dishwasher and found the rubber on the impeller seal had deteriorated causing the leak. If this is all that is wrong with your unit, it is well worth the repair attempt. Find the service manual pdf on servicematters (dot) com for detailed instructions on removing and re-installing the part. The only thing I have to add is the on my first try installing the part, I still had a leak. I may have just had the motor/impeller slightly mis-aligned (the water tight seal is actually the carbon disk on the impeller rubbing against the carbon disk on the seal seat in the pump housing). On the second attempt I used silicone to glue the 'seal seat' into the pump housing (carbon side out). After waiting a day for the silicone to dry, the dishwasher ran without leaking. It continues to be leak free several weeks later.
