How to Troubleshoot & Replace Whirlpool AP4324823 / W10168822 Dishwasher Sump Housing

Looked up Appliance Parts Pros You Tube video - video described parts that typically cause the leak in that area. Ordered the part which arrived quickly - followed video instructions to replace part; and the dishwasher is fixed. 

The leak was eliminated by replacing the sump housing and installing a new o-ring on the turbidity sensor. 

Replaced sump housing and diverter motor. 

Followed the instructions in the AppliancePartsPros.com video. 

Replaced the Diverter Motor and Sump Assembly. Note: The Diverter Motor included an in-line fuse, but not any explanation/documentation if/why this was required. The Sump turbidity sensor hole was looser than the original sump, and the cover on the pump motor connection was also loose (had to hold the cover on with tape). No leaks yet. I was recommended to replace the sump with the diverter motor (due to the seal), but not sure if this was necessary or not. 

Replaced sump and diverter motor. There were several issues with the replacement parts: The sump came with two clamps to attach the pump to the sump. The smaller of the two clamps was too large and would not tighten around the hose. The larger of the two clamps was too small and would not fit around its hose. I had to find replacements at the local hardware store. The diverter motor came with a small instruction sheet telling me to use the enclosed grease on the shaft of the motor. There was no grease. It also came with a wire pigtail with two fuses but no instructions for its use. Whirlpool needs to do a better job of quality control!
