Hi Randy its a DLX series SHU42L 05UC/18. Sorry about the time here - I had to fire up computer.
Roger that - low pitched whirring sound. When cleaning out and checking drain process there was piece of broken glass in the small cup shpwed filter (ie downstream of). carl
Okay so you have checked the filter? If so and by your symptoms and what you said you found and have already done then you are correct that the pump has gone bad. It has become dislodged from the motor as they are build together. So, in short you are going to have to replace the pump and motor assembly which will run about $200 for the part if you do it yourself. Sorry about the bad news and I am here for further assistance and thank you for your time and patience, Randy.

If I understand correctly I can gain access by removing d/w unit and flipping it over. The wash pump will be the larger of the two and if tested the motor will spin but not turn the impeller.
