Page 2: I did more research and found that the only reason I would need to get the sump would be to get the shaft seal for the dvtr motor. A rather expensive option if all you need is the seal because you can't purchase the shaft seal separately. So, I decided to remove the dvtr motor and pull the shaft seal. After a bit of cleaning, I reassembled the seal and motor but this time positioning the seal with the groove side towards the motor as it seems to fit onto the shaft shoulder better (this is opposite of how the seal was originally installed). I've run the dishwasher several times now and have yet to see a leak.

My question now is, what is the proper orientation of the pump shaft seal? groove side up towards the sump, or down towards the divertor motor?
