Remove old seal by pulling out tabs one at a time.

To install new seal, I had to remove the front control panel and door panel to access the back side of all of the slots that the new seal tabs go into. Using needlenose pliers i pulled each tab individually until they were locked into place.
Replace door and control panel.

Detergent Cup would not open during wash cycle

This repair is very simple. Partselect.com sells a repair kit for this problem that you can use but for simplicity the entire unit is not that much more. First remove the four outside lower philips head screws on the inside of your dishwasher door. Support outer door panel while removing screws. This will remove the outer door panel to gain access to the detergent cup. Remove panel by pulling out bottom first then slightly pulling downward. You will then see the detergent cup. Unplug the two leads that are connected to the unit keeping in mind their orientation. Remove the five screws that hold the detergent cup in place. Remove the cup assembly and gasket. Clean gasket area and install new cup and gasket. Reinstall five screws (do not overtighten) and plug leads back in. To reinstall door panel position door panel at a slight angle and install top first sliding upward into place under control panel then push inward at bottom. Reinstall the four philips head screws on the inside and you are finished. The complete repair will take you less than 30 minutes.

I attempted to fix it about a year ago. Took apart the screen center stem and water spinner.
I could not find anything wrong. The machine was used very infrequently over the years. Recently my wife approached me again to fix it and knowing I didn't find any thing the first time: I took the lower panel strip off and found the translucent belt broken. I found your site matched up a belt size and ordered it. Three days later it arrived, I installed it and everything seems to work. The water drains and I'm back in business. It was so easy I was embarrassed I did not fix it the first time.

I pulled the dishwasher out & watch it complete 1 cycle : water was leaking at a through hole used to secure the upper dish rack roller to the cabinet : the nut & seal holding the roller was loose allowing water to drip down the outside of the cabinet under the insulation.: water dripped onto the belt causing belt to slip : many water marks around the pump ; as a precaution i replaced the pump bottom seal & the pump to chassis gasket : I also checked the other 3 rolles ; replaced cracked top flange & installed a more flexable water supply hose .

Right Side Door Springs Broken

  • Customer: Rock from Freeport ME
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers, Wrench(Adjustable)
  • 11 of 13 people found this instruction helpful
With the dishwasher door open remove the 3 srews connecting the top of the dishwasher to the bottom of the kitchen counter top. Remove the lower access panel from the dishwasher and lower the dishwasher about 1/4 inch in the front and back of the dishwasher). Once you have lowered the dishwasher enough slide the dishwasher out about 6 inches (enough to gain access to the door springs on the left and right side). Remove all broken spring parts and replace using new springs. The left side of the door contained a single heavy duty spring and the right side of the door contained a heavy duty and light duty 'helper' spring. I replaced only the right side springs since the left side spring was in excellent condition. When the springs are installed slide the dishwasher back into its original position and raise the dishwasher back up to its original height using the front and back adjustment screws. Replace the 3 screws holding the top of the dishwasher secure to the bottom of the countertop. Ensure that the door opens, closes and latches smoothly and then replace the lower access panel. Job done.

No spray-arm motion, no drainage (broken belt)

  • Customer: Paul from Piedmont CA
  • Difficulty: A Bit Difficult
  • Time to Complete: 15 - 30 mins
  • Tools Required: Nutdriver, Screw drivers
  • 7 of 9 people found this instruction helpful
Getting the new belt installed is a bit tricky; it seems too small to span the pump and drive pulleys.

Nevertheless, start with the belt positioned in the drive pulley and stretch it so one side fits into the slot of the pump pulley. Using both hands, crank the pulley over until the belt "rolls" into place. It may take several tries as the workspace tends to be rather tight. Good luck.

Detergent Cup did not work

  • Customer: Reavis from Asheville NC
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers, Socket set
  • 6 of 6 people found this instruction helpful
I would recommend getting the entire unit. I could have replaced the electrical component only, but the other parts were deteriorating.

I removed the 4 screws in the lower side of the door and removed the front.

I lossened the 6 screws holding the detergent cup. This was done with a small hex wrench.

I replaced the dispenser and connected the wires back onto the electrical sensor.

I put the front back on the door and tested the repair. Worked fine

I will be replacing the door gasket next. I found evidence of leakage when I removed the front of the door to replace the detergent cup.

belt broken, dirty water remaining in washer

  • Customer: james from smithtown NY
  • Difficulty: Really easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Socket set
  • 6 of 7 people found this instruction helpful
I had already loosened the motor from inside the tub....so it was fairly easy to wrap the new belt around the motor/pulley system.... even though the old broken belt was 2 inches longer than the new belt(probably as a result of age and use, but the new belt is obviously the right size!) Once in place, I did have to take some care in screwing down the seal from inside being as it wanted to go more to one side than the other from the pressure of the tight belt, but all in all, it wasn't so bad. Unfortunately for me when I put the dishwasher on, I thought the dirty water problem would go away, but I soon learned that I also had a clog in the plumbing. I guess I'll never know if one thing caused the other or it was just 2 things going wrong at the same exact time. But everything is perfect now. Also, the part I ordered was at my doorstep in less than 36 hours!!!! That's fantastic!

intake water valve was stuttering causing water hammer

  • Customer: roy from cambridge MA
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Nutdriver, Pliers, Screw drivers, Wrench(Adjustable)

First I shut off the water intake. Then disconnected it from the valve assembly. Then disconnected the hose on the other side of the valve assembly. Then removed and replaced the valve assembly, disconnecting and re-connecting the 4 wires attached to the 2 solenoids. Then re-connected the water intake and hose. Then turned the water back on.

Then, noticing it leaking slightly, had to do it all over and include a small amount of teflon tape on the brass fitting that screwed into the valve assembly.

Phew.

Door Spring broke

Removed under-door front panel. Removed broken spring from right side. Hold door half open, insert spring with plastic bearing into hole in door hinge. Pull down to seat bearing in hinge. With needle nose pliers insert spring into hole at base of washer. ( You do not need to pull washer out of position)

Left side Door Spring broken

First, I removed the 4 screws & Toe plate assembly below the door, exposing the undercarriage. The springs for both the right and left side are visible. Secondly, to help gain access to the springs (and for ease in reattaching the new sping to the appropriate tension bracket), I opened the dishwasher door and unscrewed the two small screws (located above the door) that secure the counter-top attach brackets to the underside of the counter. This would normally allow you the opportunity to simply pull the diswasher out a few inches from the counter for easy access. In my case, the lip of the counter did not allow me to pull the diswasher out very far, but I was able to angle it just enough to make access easier. Thirdly, I referred to the diagram that accompanied my replacement spring to make sure that I had the spring positioned properly. There appeared to be a slight difference between tension bracket spring angle for attaching the spring to the door vs side bracket. Fourth, I attached the vinly piece provided to the top spring connection and simply pulled down on the spring to create enough tension to attach the spring to the lower side bracket. Finally, test the door to make sure you have the proper resistance. Push the diswasher back into it's original position, realigning the top bracket holes and reattach the screws that secure the counter top attach brackets. Put away your tools, pack your patience and you are done. It's easy!

DIshes not getting clean. Cover of detergent cup sticking half way.

After nearly 20 years of use (and no service) my Maytag dishwasher stopped getting dishes clean. I called Maytag and they made me an appointment with a nearby service center. The Maytag person also suggested I do a run with an open container in the dishwasher filled with a couple of cups of white vinegar – since that dissolves the white scale buildup from hard water. That helped a lot. Yay Maytag!

I had 5 days to wait for service, so I started Googling. I found very negative reviews of my local service center, but I also learned that I could buy a replacement detergent dispenser online and I found excellent simple instructions for installing it. It arrived in two days and I installed it. The hardest part was removing the front panel of the dishwasher to get access and supporting it while taking out the last couple of screws – then holding it in place afterwards while putting the screws back in. I recommend having a second pair of hands!

I also realized that the two rotating spray arms (at the bottom and at the top) weren’t rotating! They’re easy to remove (just unscrew the center component), and I found that many of the holes were clogged – including all the ones pointing sideways that make them spin. I had to force water inwards through the holes to dislodge the debris, then I filled the arms with water through the center hole and sloshed it around to clear things out. That worked. I put it back together – and the dishwasher is now as good as new!

For good measure I took the cover off the strainer in the bottom to clean it, but surprisingly the strainer was almost completely clean.

I cancelled the service appointment, of course. I’m sure I saved a lot of $$$.

I had read that recently mandated reformulation of dishwasher detergent with lower phosphate content makes it less effective – but I’m not seeing that: a little simple maintenance and my dishes are 100% squeaky clean again!

Gasket was leaking

  • Customer: Mark from Bloomingdale IL
  • Difficulty: A Bit Difficult
  • Time to Complete: More than 2 hours
  • Tools Required: Nutdriver, Pliers, Screw drivers
  • 4 of 5 people found this instruction helpful
Removed the gasket by pulling it's tabs out of the metal slots in the door. This was accomplished by accessing the inside of the door.
Then I realized that I had to dissassemble the side and front panel of the door to install the new gasket. The reason is you have to pull the tabs through the metal slots in the door from the front side. I used needle nose pliers which worked well. Then I had to reassemble the front and sides of the door. No more leaks!! for now. Takes some time if you do it by yourself. Budget at least 2 hours.
