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!

Dishwasher heating element bad

I could not reach the heater element nuts from under the dishwasher so had to pull out the dishwasher. I removed the screws around the front of the dishwasher and pulled it about half way out before the water inlet pipe and the electrical wires stopped me. I shut off the water, unhooked the copper pipe, and unhooked the electrical wires (shut off circuit breaker first). Pulled the dishwaser out so I could remove the element nuts and wires to the element. Removed the old element and installed the new one - the old nuts would not fit. I went to a local appliance parts store and found that my element is no longer made. I had the correct replacement element but you need to order the nuts also. Luckily, the local store had a small brass nut that worked. Reattached the electrical wires to the element, pushed the dishwasher half way in, reattached the water inlet and electrical wires, pushed the dishwasher all the way in and scewed back into the cabinets. All is well now and the dishwasher is working much better.

Drain pump noisy

  • Customer: Scott from High Point NC
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers
  • 8 of 9 people found this instruction helpful
As others have described once you slide the dishwasher out and tilt it for access you simply remove the discharge (use something to catch the water), torx screw that secures the bracket to the unit, and twist counter clockwise until the pump is free from the drain tub. Reassemble in reverse order

Small / slow leak at bottom corner of dishwasher door.

  • Customer: Adam from Acworth GA
  • Difficulty: Really easy

After examining the door and main seal around the dishwasher I thought everything looked okay. I looked online to order a new seal anyway and discovered from others that the leak was probably the insulation strip inside the door rather than the seal around the dishwasher. I ordered an insulation strip and it arrived a couple days later. I removed the seven screws of the interior door cover and disconnected the electrical. After removing the old insulation strip and installig the new one I reconnected the electrical wiring/plugs, put the door cover back on, and reinstalled the screws. Total time was about 15-20 minutes and the leak stopped. It was very easy and saved the cost of a repairman or a new dishwasher. I'm very glad that I "listened" to others and went with the new insulation strip.

Dishwasher wasn't cleaning well, especially top rack

  • Customer: Casey from Wadsworth OH
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Pliers, Screw drivers

I wanted to get the dishwasher cleaning better and thought that maybe the accumulator needed to be replaced. I figured that I'd swap out all the spray arms as well, just for good measure.

I needed Torx screwdrivers (T15 and T20, I think - not 100% sure on that) and patience because there's really quite a lot of screws to get the accumulator out. Finally got to it and it didn't look damaged, but replaced it anyway.

The spray arms are easy - they just snap in except for the lowest one, that had a plastic nut. I ordered a replacement nut just in case I broke this one (you know how that goes) taking it off. Well, it took pliers, but it came off ok.

In the end, my dishwasher is happy and cleans much better now.

Upper Rack not Cleaning

  • Customer: Stephen J from Sammamish WA
  • Difficulty: Easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Screw drivers

First I read all the reports for not cleaning properly already listed on this site. I had to replace the docking station with flappers. When I removed the station I lost the flappers down the water delivery tube just like Jon said I would in his repair post so I removed the water distribution assembly fished out the old flappers and snapped in the new.
But then I figured I might as well check out the accumulator while I was in the tub anyway - I had read that you need Torx screwdriver bit, which I had, undid the screws, pulled out the accumulator screen which was about 80% clogged, discovered I need a new chopper blade and my impeller is disintegrating, put it back together and lost ten minutes looking for the three screws I had incorrectly put in too soon, and now it is cleaning a packed full load like it was supposed to do.
**I love this site - I went to the virtual repairman and it listed every problem I had with this appliance in the order they happened (door latch broke years ago). - I think I am going to look up stuff that I own so I will know ahead what could go wrong with them.

And absolutely NO DUCT TAPE was used in this repair.

Lost the faucet adapter

  • Customer: Victor from Demotte IN
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Pliers

I had to replace the faucet in the kitchen sink orignnally. However since I use a porteable dishwasher, its hose connects to the kitchen faucet. The new faucets aerator is threaded differently than the old so that the dishwasher adapter would not screw in. I had misplaced the adappter kit that came with the dishwasher last year, so I ordered the adapter from partselect.com. when the part came a few day it was a simple as screw out the old aerator, screwing in the new adapted and then putting the modified aerator from the old faucet back in so that the dishwasher can be connected as needed.

Motor would not turn the impeller, no wash pressure.

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.

The adapter still needs another union to fit to the faucet . I have tried Ace Hardware, Lowes, Menards, Danco, Price Pfister and many online plumbing supply and hardware stores and am not able to find a union or combination of unions to fit.
I need an adapter with two 55/64-27 male ends.

Water leak from the dishwasher door

After replacing the door gasket and seeing that this wasn't the problem, using the schematics found at partselect.com I finally realized that it may be the insulation foam strip. I ordered the product and received it very quickly. Installation went fairly quickly. It was easy to remove the old foam strip and install the new one. The only problem was that the foam strip was about 1/4 " too short and it didn't cover the entire bottom. I improvised a little bit and cut off some of the old strip and covered the gap. So far the leak seems to have been fixed. In addition to the foam strip I had to buy a torx screwdriver for $11 at the local hardware store. The total spent was around $25.

Broken wheel, broken fingers

  • Customer: Todd from Topeka KS
  • Difficulty: A Bit Difficult
  • Time to Complete: 30 - 60 mins
  • Tools Required: Pliers, Screw drivers
  • 9 of 14 people found this instruction helpful
The rear right caster (wheel) under our fairly new portable dishwasher broke. Upon looking up the part, I discovered that it did not bolt into place, meaning that the exterior skin of the dishwasher did not have to be removed and that more than likely I could fix it myself.

The replacement wheels from Partselect were nicer quality than what the original was and showed up just two days after they were ordered.

However, getting what remained of the broken caster out was frustrating. I am not unhandy around the house, having put in two new bathrooms and a staircase.

But after yanking and prying on the broken caster for 20 minutes (slamming my fingers into the floor every time the pliers slipped), I could see where most people would give up and call a repairman. Finally, with help from small pry bar, the broken caster popped loose. Thankfully, putting the new in was as simple as sliding it into place.

Unfortunately, after all that work, we discovered the new caster was slightly taller than the old, leaving the dishwasher with a distinct wobble that my wife said was unacceptable. She, of course, had not been repeatedly introducing her hand to the floor.

I had ordered two replacement casters, thinking that another of the originals might break. But getting the second one out proved just as difficult as the first, even with the help of the pry bar.

After much cussing and kissing of finger booboos, our Maytag dishwasher is as good as the day we brought it home.
