Roy M Waxhaw , NC August 03, 2014 Main pump is very loud I replaced the circulation pump with a new one, since the bearings on the old one were worn out. The only snag I ran into was that some water leaked out when I laid the dishwasher down on the door. That let some water into the door panel, so I had to take that off and dry some insulation.
