Seal and Chopper Kit

Inside the Dishwasher on the bottom of unit, I removed the dish cart. The removed the sprayer arm with an adjustable wrench on the plastic nut on the center top. Then removed the top three screws with a Torx 20 screw driver and removed the plastic cover, then removed the single screw above the black plastic water pump piece and took it off. Then removed the six additional screws that were then displated after the previous cover was exposed. Finally I unscrewed the ivory colored plastic shaft which holds the food processor blade from the metal motor shaft with a adjustable wrench. Upon inspecting the ivory plastic shaft I noticed that the threads were stripped inside it. Which means it didn't turn when the motor would turn and wouldn't drive the water pump.

I ordered the replacements and noticed that the replacement for the plastic ivory colored shaft was a metal shaft. It had new pieces as the food processor blade had notiches in new places. The kid had all the replacement parts and a good set of instructions for what to replace and where it would go.

Then I assembled the washer as I had taken it apart. And it worked perfectly the first time. It has been repaired and working for a few weeks now without incident.

First I removed the lower spray arm by removing the middle retainer nut. Next remove the 3 screws holding the outer shroud in place. Next remove 6 screws holding the water pump top housing in place. Under this housing you will find the impeller which is retained by a screw. Check the impeller closely for cracks especially near the center hex portion of the impeller. Replace if you have any doubt of it's integrity. Next remove the lower pump housing that has the screen material in the center. What I found was the nylon part that attaches to the shaft of the motor was stripped so the impeller would spin in it's normal direction ( counterclockwise) but under the load of water it would not. So I ordered a new impeller and seal kit with a metal sleeve and chooper blade. Follow the instructions provided in the new kit a reassemble accordingly.

Looks like Maytag knew this was a problem. My chopper sleeve (plastic) was stripped and causing the impeller to not spin. The replacement part was all metal and was very easy to replace the old one just by removing screws. The replacement looks to be very sturdy and should last a lot longer than the original. Thanks.

I removed the lower wash arm held by a single center plastic coated nut with pliers.

I then removed the six pump housing screws and the three filter cover screws.

This allows access to the pump impeller which is held by one screw. Once it is removed the filter plate, chopper and motor seal can be removed.

I actually had done this before to find a noise. At the time I noticed the impeller had become shorter due to plastic breaking off the impeller. It still fit the motor shaft so I just cleaned out the plastic and screwed it back on. I did not check for water leakage until I noticed loose flooring material a couple weeks later.

This is the mistake I made. The impeller is made so it presses down upon the motor shaft seal expanding it to seal out water. Because the impeller was missing the lower skirt it was too short to but enough pressure upon the seal to stop leakage.
Never use a impeller which is damaged in any way.

Due to this error I have had to buy a motor assy also. It was destroyed by the water.

After finding out that the impeller shaft was stripped (plastic) I quickly found the correct replacement on partselect.com by using my model number.
You do not have to remove the dishwasher, if you know what is wrong. But, throw the breaker switch and turn off the water! After removing the spin washer arm, Undo all of the torx screws and pull out the plastic filter looking plates along with the center plastic water jet. This jet provides water for the upper washer assembly. You may have to pop that upper assembly out to protect it from damage.
The black impeller should just pull out if the plastic shaft is stripped. Otherwise, unscrew the small torx head and remove the impeller. You can remove the blade at this time and unscrew the plastic shaft by unthreading it while keeping the motor from spinning. (I shoved a screw driver underneath the dishwasher through the motor. Also the motor is just floating on the rubber gasket and can easily pulled out to accomplish this task. It's heavy and has a plug attached to it. You'll see where you can shove the screw driver. This comes in handy while installing the new shaft, because it is metal. Which is a great, long awaited upgrade for the Maytag Quiet Series. Once you find which shaft to use, (which correct inner thread, course or fine), install it with the great directions that come with the part. Putting all the stuff together is not as bad as one would think, there is only one way for it to go back together. After installation is complete, turn water and breaker switch back on. Run a cycle and listen for the washing cycle against the wall of the washer. If you cannot tell the difference, you can unscrew the white lock arm and insert it into the door. Turn it on and watch how a dishwasher works. Get ready to get a little wet. Towels!

Not a bad repair once you diagnose the problem. Took me three tries to figure it out. Just make sure you follow the instructions. I used an allen wrench to hold the motor in place while tightening the part onto the motor shaft, this way I didn't have to remove and flip the dishwasher to do the repair. The good news is the replacement part I needed was metal instead of plastic, thus I should never have this problem again. I don't understand why it was plastic in the first place but all of my appliance problems seem to be made to fail after several years of service.
Repair was

Removed filter cover and filter and found the plastic chopper sleeve was stripped out. Followed instructions that came with the seal kit to replace it.

I first listened carefully and noticed that during cycling, the electric motors could be heard starting, stopping, and apparently running normally during both wash and emptying cycles. However, no water was being pumped around during the wash cycles, while emptying (which uses a different motor) worked normally throughout all cycles. Thus it seemed to me that the electronic programming was working correctly in turning both motors on and off as necessary. So I figured somehow the wash motor impella was not turning and pumping water, despite the fact that the motor was indeed running correctly. So I removed all the plastic housings, the screwed on impella, and the metal chopper at the base of dishwasher. Then I was able to easily pry the old plastic chopper sleeve right off of the electric motor shaft (normally it is screwed on and cannot be pryed off). Since the plastic threads inside the chopper sleeve were completely stripped, the motor shaft would turn but the impella would slip on the shaft and not be driven. The replacement sleeve was much better constructed (metal not plastic). It could be easily screwed on to the motor's driveshaft after lifting the old rubber seal and gently holding the motor shaft with a pliers (carefull to avoid scratching the shaft). I removed the old rubber seal nd replaced it with the new one from the kit, right over the newly installed metal chopper sleeve. Next, I easily centered the metal chopper sleeve and pressed in the new seal after reinstalling the plastic/metal chopper screen, using the temporary jig included in the kit. Then the jig was discarded and the impella simply screwed onto the chopper sleeve (using the appropriately threaded hold-down screw provided in the kit). Finally, the rest of the plastic hardware is screwed in place. Waahhlaa...now impella is motor driven again and blows water hard into the dishwasher during the wash and rinse cycles. Total cost of job to do-it-yourself, $29.50 including shipping (which only took three working days). Estimated job if down by appliance repairman, $140 (assuming the repairman didn't first erroneously blame the problem on faulty electronics then charge you hundreds of $$'s to replace circuits which were not broken to begin with, only to find the dishwasher still not washing/rinsing after his expensive electronic circuit replacements. The actually mechanical fix was cheap and simple. Truthfully, there is no excuse for Jenn Aire to ever use a plastic Chopper Sleeve in their dishwashers to begin with.......carefully planned obsolesence if you ask me. Oh well, it works perfect now. I doubt if even the four marbles my 4 year old had tried earlier to wash in my dishwasher (stripping out the original chopper sleeve) would do any damage to the metal replacement. However, I don't plan on testing my hunch. A simple fix, but a slightly challenging diagnosis which relied on a keen sense of hearing and a quiet workplace. Seems many people in these blogs have had the very same problem with their Jenn Air/Maytag dishwashers, and have made the same diagnosis and the same simple fix. Thank you mucho, PartSelect.

I removed flowplate assembly, chopper assembly, found that the plastic spindle was stripped causing arm not to spin. In the new seal kit, the spindle was made of metal (much better design). I replaced the spindle, chopper, and filter assembly (old one was caked full of gunk). Worked like a charm. A previous post helped me figure out the problem.

Impeller bolts to plastic chopper mount which is screwed to the top of the motor. Threads on chopper mount were stripped causing impeller to not spin fast enough (replacement mount, which is part of the chopper kit, is metal). Installtion was not difficult.
You have to reach underneath the washer and wedge a screwdriver on top of the motor to hold the shaft from moving.
