Upper Rack not Cleaning

  • Customer: Stephen J from Sammamish WA
  • Difficulty: Easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Screw drivers
  • 4 of 4 people found this instruction helpful
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.

Dishwasher arm not spinning

  • Customer: Joseph from Warwick RI
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Screw drivers, Socket set, Wrench(Adjustable)

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.

Plastic handle latch was cracked and door was very difficult to open/close

First turned off power to dishwasher. Then, I removed all the screws on the dishwasher door. Removed old plastic door latch from wire assembly piece. Pressed on latches for square small wire boxes connected to wire assembly piece to be able to handle wire assembly plastic piece without attachment to dishwasher. Tried to snap door handle to wire assembly plastic piece, but didn't seem to fit - was too tight. Checked for discussion online and found that it required heavy pressure to snap in place. Used pliers to clamp down on outer plastic on wire assembly piece to squeeze fit door latch plastic hooks in place. This was difficult, but with heavy pressure finally managed to snap in outer hooks. Then with difficulty snapped in inner hooks. Was afraid of breaking new plastic piece, but all worked out well. Door has never opened and closed so well!!

Broken Door Latch

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

First, I recommend asking PartSelect for help to insure you have correct part. They tell me the pictures on the web site are provided by Maytag and are copywrited so they can't change them. The pictures are incorrect and misleading. However, it's a known problem, so the PartSelect people will steer you in the right direction. Bottom line in my case, I needed the lower cost part that included more pieces (counter-intuitive so I was glad I called). Got the right part the first time in about 3 days regular shipping.

As far as install, you need a "Torx" screwdriver (screw heads have a star-like pattern) to remove the screws along the inside of the door. From there, the old latch is accessible and easy to remove. As others have mentioned, the hardest part is removing the wire harnesses on either side of the latch. They have a slide on compression clip holding them on, and I think that time and ambient moisture must cause them to get stuck very tightly. I originally thought there was something locking them on, but in the end, I was able to pull and wiggle them loose with by applying slight inward pressure on the prongs with long nose pliers. You have to be careful not to damage the parts when attempting to pull them apart. It's nice that the part I ordered includes new switches, so if I caused any damge removing the old ones, it didn't matter. Just take extra care on the side with the wires and plastic connectors, since those parts aren't included and are more involved to replace if you damage them.

Overall, a very simple repair. The repair stories from others on the site were very helpful and gave me confidence when I ran into the small snag mentioned, since others had the same problem. Hopefully the additional detail I've provided on that issue will help fill any gaps.

Lower basket was dry rotting

Not being very computer literate, the most difficult part of the entire venture was navigating your web site. But I finally found the part I needed. I paid on line with a credit card, and received the part within a few days. I popped it in the dishwasher, and it took three days before my son noticed it.
He was surprised and I was proud to say " I ordered it on line."
All's well that end's well.
I would difinately use your service again.

Dishwasher wasn't heating the water and dishes were not getting clean.

This isn't a how to fix it....it's what part was bad. I had originally contacted the local Maytag repair center and the owner swore up and down that our problem had to be the thermostat and not the heater. He said he had only replaced maybe 5 heaters in 15 years. But our heater looked like heck, with hard water deposits and all, and it wasn't that old, but we went ahead and ordered the thermostat from PartSelect, which came in a day. The problem wasn't the thermostat, so we ordered the heater from PartSelect (again, only one day delivery) and our dishwasher is working again. The heater coil actually had a hole in it from some sort of corrosion. My 18-year-old son did the repair job in a jiffy.

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.

remove old seal, put in new - my 10 yr old could do it. Note - there is a white mark on the back of the seal indicating the middle so you can line it up when installing the new seal - makes it easier.

If you don't hold door when opening, it will drop down hard

First I removed two bottom plates (two screws on each) Then I pulled dishwasher out about six inches. That's as far as it would go because I did not disconnect the water and drain hoses. That was enough to remove the broken cable and collect the disabled spring. I then reattached the new cable to the spring and reworked them into position. NOTE: There is a right and left cable and spring set-up. I used the "good" side as a guide. I then pushed the dishwasher back into place and replaced the two bottom plates.

Latch Assembly Mechanism Broken

  • Customer: JOHN from GAINESVILLE FL
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Screw drivers
  • 4 of 5 people found this instruction helpful
If you have already figured out what the problem and the part number is, and have gotten this far, then you probably already know how to fix it and do not need instructions. But if you do, I took the following steps:

1) Use a #T20 star bit to remove the screws from the inner door panel. [Note: I would use a manual screw driver as opposed to a drill/driver, because you are less likely to accidentally strip the threads in the screw holes];

2) Lift the panel up and detach the wire harnesses from the metal receptacles attached to the old assembly.

3) Remove the old latch assembly, and then press the wire harnesses into the metal receptacles on the new assembly. [Note: You may have trouble getting the wiring harnesses out. If you pull hard enough you can get them off, but if you truly cannot, simply detach the metal receptacles from both the new and old latch assemblies and place the old metal receptacles on the new assembly with the wire harnesses still attached. If you choose this method, be careful with the little plastic retainer bars that secure the metal receptacles, they are pretty easy to break.];

3) Put the new latch assembly in its seating and re-secure the inner door panel. If you used a drill/driver before, I would really switch to a manual driver at this point.

4) Take the dishes out of your bathtub, and place them in the dishwasher.

5) Close the door back.

6) Stare.

Broken Dishwasher Door Latch - Assembly Replacement

  • Customer: Gail from Sharpsburg GA
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins

  • 4 of 5 people found this instruction helpful
Being a fairly technical female, I decided after Internet research to replace this part by myself. It could not have been easier - even after reading several Internet horror stories. I believe the major difference being I replaced the entire assembly, not simply the latch.

You need a hex-head allen wrench to remove the inside cover of the dishwasher door, and some sort of pliers to remove the old unit. I used vice grips since I am a wimpy girl - they worked nicely (this took the longest time).

Step by Step:

Turn off the power to your dishwasher.

Remove the door screws and carefully lift it to access the door latch assembly.

Remove the old door latch by unplugging the black and white electrical mechanism. Pay close attention to which side the black and white connections are removed from for reconnection reasons. This is where I had to use vice grips. It took a bit to "unplug" the old latch assembly.

Once the old latch assembly is removed, position the new latch assembly and reconnect the electrical source.

Carefully reposition the door and replace the screws.

Turn on the power.

Run a short cycle (I used rinse) to make sure that the unit was replaced correctly.

Can it be any easier than that??
