How to Troubleshoot & Replace Whirlpool AP5618621 / W10445975 Motor To Sump Hose

The seal for the diverter motor shaft started leaking. The only way to replace the seal is to replace the entire sump, which means you have to remove all the stuff connected to it, including the main pump. The main pump is connected to the sump via a rubber hose with one time use clamps. These parts worked well.

I am 75 years old. I had to pull dishwasher out from counter, as large style tub is so close to floor. After removing the lower cover, could see water pouring out but not from where. I flipped dishwasher on front and saw that motor to sump hose was chewed through. (we have moles that come inside). Got on-line, looked up diagrams, found parts needed plus new heater. Parts were delivered next day, replaced parts gotten same night as delivered. I tested dishwasher while not under counter. no leaks. put back in and used next day. 

Replaced sump seal. Water dripping down diverter stem. This seal is part of sump seal. Since you have to remove all parts from seal, replaced all rubber seals that I could. Everything was aged, so why not while your under unit anyway. Replaced diverter motor also since water was dripping onto it. I used o ring grease instead of water, to help installing. WATCH the videos!!! Step by step and very helpful. They show a few tricks that will aid in the install. 

I contemplated replacing it but was able to find all the parts right here and fix it within an hour. Now it works great with no leaks. I have been using AppliancePartsPros.com to maintain all my appliances as it has saved me thousands of dollars over the years. 

These were the parts that were recommended to.be ordered to fix the problem. 

I replaced the motor to sump seal and based on the video recommendation I also purchased the motor to sump hose/clamps. I am so glad I bought the hose/clamps because it was very difficult to remove the existing hose/bands and would have been very difficult to reinstall. The repair video on the AppliancePartsPros.com website was very reflective of the repair job. One issue I ran into was the water supply valve did not completely shut off due to the age of the valve, so I had to shut off the main water supply. I also recommend being careful because the quantity of water that came out of the dishwasher drain hose was more than I expected so have a few extra towels on hand. When reinstalling the motor, I was worried that it did not go flush into the new sump seal so removed it to try reinstalling it because there was still a little gap between the sump seal and the little ribs on the motor housing. I zoomed in on the repair video and it seem to show the same small gap. We have run the dishwasher a couple of times with no leaks, so I consider the repair a success. Thanks for the repair videos. They definitely help make the job easier and know what to expect. 

I found the parts I needed on appliance parts pros. I watched a couple of quick repair videos. Bam, problems fixed in no time.
