Whirlpool WP910934 O-Ring Seal OEM Part

I first wanted to get the dishwasher running, before ordering the spring links. So I disassembled the pump / motor assembly to determine the reason the motor would not start. My wife cleaned all of the parts in the pump assembly. I took the motor apart and discovered that the lower bearing ( a sleeve type bearing) was dry and dirty, and was the culprit for the motor seizing. I cleaned up the bearing and lubricated it with SAE 20W. I also packed felt inside the cavity adjacent to the bearing. and saturated it with 20W. I reassembled the motor / pump assembly and installed it in the dishwasher. I noticed that the seal (part #902882 which is located under the drain impeller), was slightly damaged. I was also concerned that the pump to tub gasket had also had better days. However I put the dishwasher back into service. It worked just fine, with the exception of water leaking around the motor shaft during the 3 drain cycles. I was thankful for the rubber shaft boot located above the splash plates. It prevented the water from getting into the electric motor. I placed a Tupperware tub under each end of the splash plates. I had to empty them after each drain cycle. So, when it was time to run the dishwasher, I had to remove the lower access panel and monitor the water level of the tubs. I received the spring links, so after the second run, I replaced both links. This entailed unhooking the water supply, taking the two screws that secure the dishwasher to the counter, and pulling the dishwasher out far enough to reinstall the spring that had the broken link. I went ahead and changed out the "good link" (now a spare) with a new one. The door now, works like new and doesn't free fall when opened. By the way, our dishwasher is a Maytag model MDB6800AWW, and has been in service for about 18 years. My wife loves how well it cleans our dishes. Unfortunately, many of the repair parts to keep it running are unavailable, including the motor, relay, and even the seal below the drain impeller. I was able to buy a used pump / motor assembly from e-bay, to use for parts. I'm still trying to find another seal #902882. I've tried a lot of parts houses (including Sears) with no avail. However, after the third run, I was happy to see that only a tablespoon of water had leaked out from the drain assembly. I appreciate the prompt service in getting the parts which I can still procure. I have completed Penn Foster's appliance repair course, and like the challenge of repairing my and my family's appliances. The repair on the dishwasher, was a great learning experience. I hope to gain enough expertise to have the confidence to repair appliances on a part time basis, for a little additional income. Again, thanks for your professional service. Sincerely, Randall G.

My son fixed it. Problem was one of the spinner pieces had worked itself loose and jammed the large arm from freely spinning.

Took everything apart down to the discharge housing assembly but found nothing wrong. Unscrewed discharge housing and found rivet had come off of inner plate. Plate was resting on the impeller. Attempted to epoxy plate back on but didn't last through one cycle. Replaced housing assembly and impeller (not broken but just for good measure). O-ring for housing out of stock. Found similar one used for inline water filter at hardware store. O-ring not exact size but stretched it to fit. Worked fine.
