Do-It-Yourself Story

First determined drain discharge hose was clear. Turned of power to dishwasher. I did not find it necessary to remove the dishwasher. I simply removed the lower service panel at the floor and was able to easily remove the defective pump, unplug it, replace the small rubber check valve flapper before the pump inlet and reinstall the new pump assembly. The dishwasher surprisingly cleans and runs quietly like new again although I found no excuse for the pump failure as it is well designed. Never allow broken glass remain in the filter sump. A shop vacuum is useful to empty the sump. AppliancePartsPros.com promptly sent the correct parts as always. No hassles. Hint: the larger spring clamp is difficult to compress and position so offset pliers were useful.
