The dishwasher wouldn't fill with water.

  • Time to Complete: 15 - 30 mins
  • Tools Required: Wrench(Adjustable)

I first turned off the water to the dishwasher, then the electricity to it, then took off the front bottom access panel, I then unbolted the inlet valve from the side of the machine, undid the electrical hookups remembering which one connected to which, then unclamped the two hoses, I then put the new one back in place, redoing the hoses and electrical and bolting it back to the side of the machine, then putting the front bottom access panel back on, then turning back on the water and electicity. The one thing that may make it easier if you can is to pull the dishwasher out from under the cabinets and lay it down so the bottom is exposed. This would make the process a little smoother.

Leaking at bottom of door

  • Customer: E L from Seeley Lake MT
  • Difficulty: Difficult
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers

The initial repair was more involved due to figuring out how to get at the problem. A foam sealer strip located at the bottom of the inner door had lost it's seal. I first sent off for one and it was of relatively thin material. It was carefully installed but still leaked. I ordered another one from Part Select and it had thicker foam. It was installed right over the previously installed strip and made a tight seal. (knock on wood)

Door switches were worn. Diswasher would not operate unless extreme pressure was applied to the door.

  • Customer: James from Rochester NY
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers, Socket set

I pulled the interior of the door until I was able to get to the switches on the door latch. I determined at least one switch was completely worn while the other worked minimally. I then looked for the latch assembly and found out that it was no longer available. So I did some searching and found the exact switches I needed from PartSelect. The switches came in about 3 days which then I installed them. The dishwasher powered right up and stayed on. So in the end it was much cheaper to repair this unit than buy a new one right now. Plus, my wife is happy and so am I. Thanks PartSelect for carrying the parts I needed.

Door was leaking badly

After performing some maintenance to get the water flowing properly through the system (that's another story) the door was leaking very badly during any test run of the dishwasher.

We thought it was the gasket because the old one was calcified and dried out from years of harder water.

We ordered the new one and in minutes after receiving the new gasket we had a firm seal and our dishwasher was back in action.

Dishes Weren't Getting Clean

  • Customer: Allen from Columbia SC
  • Difficulty: Really easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Pliers, Screw drivers
  • 16 of 19 people found this instruction helpful
I surfed the net using phrases like "dishes not clean" and found a series of possible solutions. When I noticed that the water in the washer was cold, I realized it was a heating element issue. Using a multi-meter set to the lowest resistance I tested both ends of the heating element (OF COURSE I SHUT OFF ELECTRICITY TO THE DISHWASHER FIRST!!!) and found it read a steady 16 ohms. Then I followed the orange leads to the limiter, removed the leads and tested resistance and found it at near zero. Touchdown.

I ordered the new limiter, had it in a couple of days and installed in in 5 minutes. The hardest part was putting the metal cover back on the bottom of the unit.t

Water Valve would not open to allow water into DishWasher

  • Customer: Bob from Allen TX
  • Difficulty: A Bit Difficult
  • Time to Complete: 1- 2 hours
  • Tools Required: Nutdriver, Screw drivers, Wrench(Adjustable)
  • 17 of 23 people found this instruction helpful
First, I removed the foot plate(s) at the bottom of the Dishwasher. (2 screws each side)

Then I removed the two top screws at the front of the dish-washer. The screws were mounted into a board under the counter that had broken loose. (A minor secondary issue specific to my situation.)

I gently inched the dishwasher out from under the cabinets.

SLOWLY, I tipped the dishwasher over on its side, allowing the water still inside to drain into a pan. Minor cleanup required for the cup or two that missed.

I then had access to the part. I disconnected the power from the wall socket, and I closed the valve for the inlet water from under the sink.

I removed the screws holding the Water Valve to the DishWasher case. Then I took a sharpie and marked one side of one of the two power connectors, black-mark to black-mark.

When I went to disconnect the inlet pipe, there was more dripping than I expected, so the valve under the sink was not closing completely. I needed to shut off the water supply to the house for the next stage.

I disconnected the inlet water supply, which continued to drip slightly into a bucket. I then removed the coupler from the old water valve. It was badly clogged and corroded, so I went to a local HW store and found an exact match 3/8" to 3/8" right angle coupler with compression fitting on one end.

BIG TRICK, before installing the new coupler, WRAP the compression fitting threads with teflon tape. You will not be able to wrap it once it is installed. In fact, I needed to uninstall the part once after I discovered this, to wrap the threads smoothly.

Once pre-wrapped, wrap the other threads that screw into the water valve. Tighten until secure, AND aligned with the direction of the flow tubes of the original.

Match the electrical connectors, black-mark to the same position as before. (The new water valve will NOT have the black-mark on it, unless you transfer one!)

Connect the Water valve back to the Dish Washer chassis with the two screws previously removed.

Connect the inlet water back to the compression fitting with the pre-wrapped threads.

Gently return the dishwasher to upright, and then plug it in.

Open the valve under the sink slowly and watch for drips or leaks.

Run the dishwasher at the start of a cycle, long enough to determine that the valve activates, and allows water to flow. Then stop the cycle.

Gently walk the dishwasher back under the counter, observing that you do not kink the copper water inlet pipe, or the drain pipe.

Adjust the feet, if necessary, back to fully support and level the dishwasher.

Install the two screws holding the dishwasher to the cabinet front. Then install the kick plates and tighten those 4 screws.

Clean up any residual water from the process.

Leaking on right fromt of the door.

removed the door gasket by just pulling it out and pushing the new one in its place. very easy, took five minutes at most. Then removed the 7 screws holding the inside of the door in place, removed the dispenser assembly, held by two drive screws and replaced the dispenser door latch grommet. Finally, removed the insulation foam gasket. Had to scrape the old adhesive from the door as the old a\gasket had disintegrated. This took the most time. Then just pressed the new foam gasket in place. Reading the comments from others was a big help. Don't think I would have replaced the dispenser grommet had I not been warned about it. I'm sure it was part of the problem. All is well now, no leaks.

Not enough water pressure to wash soap out of dispenser

  • Customer: Duane from Las Vegas NV
  • Difficulty: A Bit Difficult

Our first effort was to replace the lower washer arm that had splits in the sides of this plastic part. While this increased the water pressure in the wash cycle some it was not enough to adequately wash the dishes. We read that someone else had to clean out the filter which was below the lower washer arm assembly. Thus, we took off the loweer arm assembly by screwing off the hold down assembly in the middle of the arm. We then took off the pump cover by removing the 6 screws that hold it in place with a #3 metric allen wrench. When we took of the cover we could see that the pump filter was so covered with deposits that it was not letting the water through to the pump. Rather than spend hours trying to clean the filter and pump cover we decided it was easier to repalce them. Thus, we ordered the parts and replaced them. The dishwaster is now working fine. We appreciated the information that others had shared that helped us find and fix the problem.

Machine began making noise as if something had let go and was beating on the machine

I removed the plastic retainer that held the lower spray arm in place. After removing the lower spray arm I was able to remove the 6 hex screws that held the cover over the filter screen and the discharge housing assembly. I was then able to remove the bolts that held the upper part of the discharge housing assembly, and replaced it with the new part that I received. The rest of the job was simply putting it back together.

Note: While repairing the broken part, I noticed a small leak under the machine around the float assembly. This was simple to fix. Remove the small lock ring on the bottom of the float. Pull the float out and clean the grease and soap scum out of it. Put it back in and attach the lock ring. No more leak and the water gets turned off when the float activates the switch. Something that everyone should check periodically.

silverware basket broken - replaced with new one

Dispenser lid would not open

  • Customer: Douglas from Pottstown PA
  • Difficulty: A Bit Difficult
  • Time to Complete: 1- 2 hours
  • Tools Required: Nutdriver

The wax motor seemed to work.
At first I thought something was broken and I tried to figure out the "theory of operation" Working the actuator of the wax motor, I COULD NOT GE THE LATCH TO MOVE THE WAY I THOUGHT IT SHOULD. I ASSUMED EITHER IT WAS BROKEN IN SOME WAY I COULD NOT DETECT OR THERE WAS A FLAW IN ITS DESIGN!

It took a long time to figure out the latch would not be worked open unless it was actually holding the lid- this positions the latch at "half mast" and allows the mechanism to "pick it up from there" and open the rest of the way. So once I figured that out, I concluded the failure was really just worn out parts that were out of tolerance for how this "half mast" position and opening was supposed to work. So I ordered all fresh pieces just to be sure, assembled it (very easy) and put it in (easy). It all works fine now.

diswasher would not drain

  • Customer: Larry from Arlington VA

  • Tools Required: Screw drivers
  • 14 of 20 people found this instruction helpful
1) turned off power to dishwasher
2) removed each piece of pump assembly (one at a time) from inside the dishwasher. I had no repair manual and didn't know that by rotating the lock lever under the dishwasher, I could have easily removed the entire pump assembly as a unit.
3) Reassmebled the pump assembly using new parts and installed in dishwasher.
4) Reconnected hoses and electrical connection
5) Turned power back on
6) Washed dishes... it's as good as new!!!!

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.
