How to Troubleshoot & Replace Whirlpool AP5650272 / W10537869 Diverter Motor

Found leak. Took apart diverted motor, and rubber grommet, replaced with newer diverted motor and grommet. No more leaks found 

Looked up schematics on several sites, viewed YouTube video on similar situation.. ordered more parts than needed, as I hadn't inspected the problem completely due to its "hidden" location under the tub. However, after studying the schematics, swapping out the part was only slightly difficult.. had to lift the power scrub nozzle out of its inlet and then twist the water inlet tubes counter-clockwise to expose the plastic disc that came with the motor. Two (2) Torx screws released the motor from the bottom of the dishwasher, and the electrical connection was easily made with the snap in fittings. I was able to return the part I didn't use. Pleased that we dodged a service call or two. 

When I renovated the kitchen, I left lots of slack in the 12-3 electrical wire and drain tube; therefore the dishwasher slid right without disconnecting anything. The online chat help was great in recommending the seal to accompany the motor, although she did try to talk me into buying the whole sump, which I did not. The motor itself went right in - a couple of screws - a couple of cannon plugs - done. The seal was a different story. I had read online that the seal is manufactured into the sump, and sure enough, it was. Using a screw driver as a lever, I inserted it into the center if the seal to lift it up just enough to get a needle nose pliers on the edge of the seal. It came right out and the new one popped right in. I was basically done at that point, just needed to reinstall sprayers, filters, etc. and slide it back in and secure it. The part arrived the next day without asking for it or charged for it. There are plenty of youtube videos out there, which I found helpful. 

Check the hose clamps before ordering the sump! I called to talk to a pro and they suggested buying the sump as well as the diverter motor, which I did. While removing the motor from the old sump, I had to destroy the old hose clamps that were on the small hose connecting the sump and motor. The clamps that were on my Kenmore were compression clamps, not the type with a screw. I checked Lowes, Home Depot and a local hardware store and nobody carries a large enough clamp with that small of a width. So, I had to stop in the middle of fixing my dishwasher to order the right clamps (part # AP5971447). I haven't been able to finish yet because I'm still waiting for the clamps to arrive, but I was able to get the new sump installed without any problems. The how-to videos are excellent. 

The shaft seal (grommet) on the diverter motor leaked. Kitchenaid said the grommet was not available individually and had to buy entire sump assembly. Whirlpool sells the grommet individually. It fits and fixed the problem. 

Took out the just out of Warranty new $800 dishwasher and tipped it over and dismantled it so I could remove the sump. Didn't need any manuals or tech support, the process is very simple, and easy to reassemble. I couldn't fathom paying someone hundreds to fix this for me. Only specialized tool needed ... that I already had, is a sharkbite pex crimper tool; I got mine at the local big box home improvement store last year to fix a few things under the house. 

The real fix was the grommet/seal that seals the diverted shaft. I went ahead and replaced motor since it had been exposed. Frustrating wear item after 3 years. I put machine on its front, pulled motor, used vinegar and baking soda on electrica l connections, lubed shaft and grommet and replaced. Grommet is placed from inside tub. Appliancepartspros is fantastic. Toughest part of job is pulling out the dishwasher 

Replaced sump, wash pump, drain pump, diverter motor, and thermostat. 

I ordered the motor and there was a little white plastic disc that came with it , that's what did the trick I wouldn't of needed the motor, but I opted to put it on any way because the other motor was all corroded from the dripping water, Husband replaced it all within 30 minutes. 

The grommet needed to be replaced but, unfortunately, Whirlpool requires replacement of the entire sump. So I purchased a new sump, a new diverter motor (even though the old one was still working but had signs of water damage) and 2 hose clamps since the originals could not be reused. The video on the AppliancePartsPros web site was extremely helpful and explained the entire process from start to finish. I consider myself to be moderately handy and I had no problem making the repair. I probably spent about 1 hour on the disassembly and another 1.5 hours on the re-assembly including time to clean some of the old parts before putting them back.
