  • 15 of 21 people found this instruction helpful
1st: Unscrewed the inside of the door (actually hex screwdriver needed).
2nd: Removed broken part (one side of handle latch (which is plastic) was broken.
3rd. Had to disconnect two electrodes that were attached to the part that held the handle (there are two small prongs that you need to push back to remove these)
4th. In order to place the handle on the groove, you need to pull apart the bottom of the housing piece (it looks like it would be a hinge, but you just pull it apart)
NOTE: Make sure you have another person hold the top portion when you pull this apart because it has a spring and will come completly apart. This happened to us and it was a pain to get it back together.
5th: place the smaller "clamps" plastic pieces in the grove and then it should slide down into the groove, which will also seat the outer "plastic clamps" into the grooves.
NOTE: It seems like the repair part was built to reinforce this part of the handle, since this was the part that broke before. It is now reinforced with a little metal rod on each side.
6th: After all that, you need to place the two electrodes back on the piece.
7th: Hold it in place and put the inside of the door back on (start a screw on one side and then go to the opposite side. This will help to align the screw holes).
8th: After I put it all back together, I turned it on to make sure it worked ok.

The dishwasher would not drain

  • Customer: Brian from Keokuk IA
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Screw drivers, Socket set
  • 15 of 21 people found this instruction helpful
First of all I shut the power off to the dishwasher at the breaker box. Turn the water off to the dishwasher. Unhook the water line and then remove the screws that go around the outside trim edge of the dihwasher that secures it to the cabinets. Then you will want to look at the adjustable legs on the dishwasher. You may need to lower the legs to get the dishwasher out from underneath the counter top. While you are doing this you should also pay attention to your drain hose. My drain hose had plenty of slack so I was able to pull my dishwasher out from underneath the cabinet and then unhook it. You should have towels or a bucket in place to catch any water that is inside the drain hose. Next I laid the dishwasher over on its left side and I was able to access the pump. I then used a flat screw driver to remove the hose clamp and remov the drain hose from the pump. I then unplugged 1 wire connector and a bracket and could turn the pump counter clockwise and removed it from the dishwasher. There is a bracket that must be removed from the old pump to the new pump. Once this is accomplished You are ready to reinstall the new pump. I took a towel and wiped the area where the pump hooks into the dishwasher to make sure all debris was removed. I then used a very small amount of gasket sealer and placed it around the "O" Ring on the new pump. Next place the pump back in the whole and turn in a clock wise direction securing it back into the dishwasher. Hook up the drain hose and the wire connector. Make sure the bracket is postioned properly and you are ready to put dishwasher back under the counter.

We were happy to find the basket we needed listed on your website, even after we could not find it on the Maytag site. It was perfect. I can't believe we lasted almost 2 years with the broken basket we had.

grinding noise during cycle

took the bottom spray arm & lower plastic pieces out, unscrewed the impeller & replaced it. the original impeller which holds the disposal blade down & wore down & no longer retained the blade. snap.

water was dripping from the bottom of the front loading door. Over time this had seeped into the insulation foam strip and formed a solid encrustation within the foam strip.

  • Customer: Dan from Clarkston MI
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers

The real cause of the leak had nothing to do with the foam strip. The latch for the front loading door at the top needed to be adjusted to hold the door in tighter to the rubber door seal. This simple adjustment stopped the leak but since the foam seal was all encrusted with dried detergent from probably years of absorbing the leak, I replaced it with your new foam strip. I used a screw driver with torx bit and removed the stainless screws holding the inner door to the outer door. Once these were separated I removed the old foam strip using a putty knife and lacquer thinner. Placing the new strip onto these cleaned surfaces was the easiest part of the whole repair.

Water leaking from bottom of dishwasher at motor.

  • Customer: Jack from Lee's Summit MO
  • Difficulty: A Bit Difficult
  • Time to Complete: 1- 2 hours
  • Tools Required: Nutdriver, Pliers
  • 10 of 10 people found this instruction helpful
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.

Dishwasher handle broke

  • Customer: Christy from Warm Springs GA
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Pliers, Screw drivers
  • 11 of 14 people found this instruction helpful
This was a very easy repair. Before I did anything, I flipped the breaker for the dishwasher and tried to turn the dishwasher on to make sure it had no power going to it. Once I was certain the power was off I removed the hex screws (there are 11) on the inside of the door panel using the hex screwdriver. Lifting and holding the inside panel up, I then used the pliers to pry the old latch assembly out of its metal prongs. Then I replaced the old latch assembly with the new one, pushing the metal prongs (by hand) into the slits of the new latch assembly. Last, I lined everything up and screwed the door panel back in place. I flipped the breaker back on and activated my child lock to make sure I had power. The handle worked perfectly. Quick and easy fix!
I ordered the part with 3-5 day delivery and actually received it in 2 days! I'm extremely pleased with my partselect.com experience and highly recommend using them for all your appliance parts needs!

Door leaks

Replaced the door seal. Removed the old seal and gently stretched the new seal and pushed it into the channel. Snipped off about 2 inches excess seal. As far as the Inner Door Foam Insulation Strip goes, it was not as easy. To begin with, the old Foam Strip was attached to the door insulation and not the door. The attempt to remove the old Foam Strip from the insulation became cumbersome, so I just attached the new Foam Strip on top of the old Foam Strip. So far, after a few cycles, it appears that it corrected the leak.

Dishwasher not draining

It was my first time repairing a dishwasher. I was a little worried. I also wasn't sure about how to remove the drain pump. Well, the hardest part was just getting the dishwasher out from under the counter. I did find a crimp in the drain line that probably contributed to the original pump going out. I fixed that, removed the old pump by removing one screw holding a stablizer bracket and twisting the pump connection. The original bracket is needed, so I removed it from the old pump, attached it to the new pump and reversed the removal process and secured the pump by reattaching the stabilizer bar with the single screw. I then slide the dishwasher back under the counter. Runs great. Easy repair. The part was shipped and delivered on time. Very impressed with the process and will order my appliance parts from you in the future.

After repairing this dishwasher 5 times during the past 8 years this one was real easy: Open door, unscrew inside cover and carefully move over to one side. Unplug soap dispenser, unscrew soap dispenser and remove. Fit new dispenser, reconnect it, put inner cover back in its place and secure it with the retained screws and you are back in operation. Hans.

The impeller was not spinning. There was no washing water.

  • Difficulty: A Bit Difficult

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!

Broken door latch

  • Customer: Leonard from Plant City FL
  • Difficulty: Really easy

  • Tools Required: Screw drivers

The repair stories on PartSelect.com told me exactly what to do.

First, I checked the inside of the door and confirmed that the inside panel of the door was held in place with about 10 torx screws.

Second, I went out and bought a set of torx screwdrivers.

Third, I TURNED OFF THE POWER TO THE DISHWASHER AT THE BREAKER BOX! Safety first!

Fourth, I removed the screws and gently lifted the inside panel of the door, and then gently lifted the broken door latch assembly out of its slot. (There were no more screws to remove, because the latch assembly is held in place by two of the door screws.) Two sets of wires, one white and the other black, were connected to the latch assembly by plug-in connectors.

Fifth, I unplugged the wires from the broken latch assembly. The clips in the plug were very tight, so I used a dishtowel to hold onto the latch assembly. I found that gave me a better grip.

Sixth, I plugged the wires onto the new latch assembly, and then slipped the latch assembly back into the slot.

Seventh, I replaced the inside door panel, and replaced in the 10 torx screws.

Finally, I turned on the power at the breaker box, closed the door, and turned on the dishwasher. It ran perfectly!

I would like tyo add that I had ordered an unnecessary part by mistake. I called the return number, and the person who answered was extremely helpful. She gave me the return authorization number and I put the part in the mail. Ten days later, I received an email from PartSelect.com confirming that the part had arrived and that my account had been credited.

The entire process was easy and pleasant. Anybody can do this! Just make sure to shut off the power at the breaker box before you start on the job.

Dishwasher heating element bad

  • Customer: Gary from Indianapolis IN
  • Difficulty: Difficult
  • Time to Complete: More than 2 hours
  • Tools Required: Pliers, Screw drivers, Socket set, Wrench set, Wrench(Adjustable)
  • 8 of 10 people found this instruction helpful
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.
