We saw where the water was coming from. Uninstalled the dishwasher. Turned it on its back so we could see everything. We saw that the pump housing was leaking. Found the part on line. We called to make sure the part was in stock and ordered it around 4 PM on Thursday afternoon. There must be a parts ware house around eastern MA because the part was at the house by 10 AM the next morning by regular FEDEX shipping.
We checked to make sure the parts matched what was on the dishwasher and then took off the old pump and motor and put on the new one. Reinstalled the dishwasher and ran a load. No leaks. Problem solved.
