Found numerous references on internet that most likely cause was due to a fouled or plugged suction screen. I unscrewed anchor tabs on top securing the dishwasher to the countertop, slightly lowered the front screw legs, turned off circuit breaker at the electrical panel, checked to verify the power was off, removed the small electrical cover under the dishwasher and disconnected the 3 wire nuts, pulled the dishwasher partially out, then disconnected the small corrugated drain hose from the discharge pump under the washer being careful to collect small amount of drain water in a bowl. Finally, carefully pulled dishwasher out from under the countertop leaving the hot water supply hose connected. Tipped washer over onto back (the frame rails are rounded in the back to help facilitate this). Had to unscrew the hose clamps to remove the rubber sump. Then stood the dishwasher back up to disassemble the plastic screen parts from inside the dishwasher. The screen was in fact plugged with white slimy deposits that when dried became chalk like. During cleaning out the white caked on deposits in the rubber sump, I accidentally pushed my screwdriver through a rubber vent stand tube and this is why I had to buy a new rubber sump. The sump rubber material appeared to be partially deteriorated which is why my screwdriver passed through it. Reassembly wasn't very easy. It was difficult to get the rubber sump boot over the plastic flange on the bottom of the tub. It helped to remove the metal hose clamp completely and to have someone hold the dishwasher in place lying on its back while I pushed and prodded to get the rubber seal over the oval flange. Once on, everything went back together easily in reverse order. It probably took me a total of 6 to 8 hours of real working time. But taking into account that I only worked for short periods of time on evenings after work and the fact I had to lug around my extra 70 lbs of gut, the constant laying down and getting back up, the 4 day wait for the new rubber sump to arrive, and my near senior citizen age stretched this 8 hours of work out to a two week home repair project. BUT, I was successful and everything is back to perfect working order. Thank you Partselect.com for having the sump in stock and to my door in only 4 days!
