Water Supply Tube WPW10077863

Pulled out dishwasher after checking the air gap, etc. Washer would marginally pump out water and could hear motor running on drain cycle. Usual mess from water draining out of hoses.

Ohmed drain motor at 24ohms, should be 16.3 ohms from repair manual. Noted check valve, a rubber flapper, was canted out from sealing surface.

New motor ohms at 24 ohms, installed new motor prophylactilly. Installed new flapper valve through the sump. Washer checked okay for drain cycle.

Feed tube assembly was ordered as upper rack flapper valve was worn into open on upper position due to normal use. Feed tube spinner was small, so the rubber flapper was scavenged from the new assembly and used on the old feed tube assembly.

I followed the PartSelect video to replace the feed tube assembly with spinner and the spray arm seal for the middle wash arm. Washing performance was better, but a couple weeks later the dishes on the bottom rack suddenly stopped getting clean. I decided I probably needed a new chopper assembly, which is identified by PartSelect as the cause of problem for 48% of the cases of dishes not getting clean. Before ordering the chopper assembly, however, I followed the video about how to replace the chopper assembly to determine whether the chopper assembly seemed to be worn out (the video shown at https://www.partselect.com/PS11722146-Whirlpool-W10083957V-Chopper-Assembly.htm). It was worse than I anticipated. I found the holes of the chopper assembly screen blocked by food, and the spinner in front of the screen had broken apart. In addition to finding the pieces of the broken chopper assembly, I discovered a treasure chest of debris, including about 8 pieces of broken glassware, 3 twister ties, a half-inch button, a 3/4-inch screw, and dozens of small pieces of metal. I poured water into the area and used a kitchen baster to suck out the water with all the pieces of debris, finishing the clean-up with paper towels. I ordered a new chopper assembly to replace the broken one, and the part arrived in under 48 hours. I relied on the same video to install the new chopper assembly. The only tricky challenge was getting the new chopper assembly back into place. I first tried needle nose pliers in two sizes, as recommended in the video, but what worked much better for me was using two chop sticks that were each about 1/4 inch square from top to bottom. Needle nose pliers are slanted, but the chopsticks did not vary in thickness and separated the screen from the spinner an even distance apart, making it easier to get the gear shaft on the chopper assembly to align in a straight line with the gear shaft on the pump motor. I also rotated the two gear shafts so the gears of the chopper assembly would mesh correctly with the gears of the pump motor shaft. The video cannot show that step very well because the man's hand blocks vision of how exactly to fit the chopper assembly into place. The video also fails to warn about possible debris around the chopper assembly and to explain how to clean out the debris. After finishing installing the chopper assembly my 14-year-old dishwasher cleaned my dishes as well as a new dishwasher. I spent a total of $110.24 on parts and shipping and invested a couple of hours total. The alternative would have been to spend $800 on a new dishwasher or wash dishes by hand. I am very, very happy with the outcome.
