MDC4000AWE Maytag Dishwasher - Instructions

clipped in the replacements and installed the assembly. Easy and thanks, PartSelect.

Took off old part. Modified new roller w'knife. Found a nut and bolt in scrap pile. Attached.

This ended up to be a (2) phase project. The first repair was to replace the door seal and inner door foam. Thanks to earlier online comments this part was really easy, but we still had a small leak. When I had removed the interior face of the door panel to replace the inner door foam, I had noticed the insulation was wet and deducted that the 'soap cup door latch gasket' was the real culprit so I had to place a second order (Phase 2). The order came quickly and in time for next Saturdays to to list. My advice is to replace all 4 items at the same time and save on mailing cost and repair time; reservoir O-ring, soap cup door latch gasket, inner foam gasket and door gasket. net repair time, about an hour start to finish.

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)

I ordered the part and it fit perfectly!! About five minutes to screw it onto my faucet and problem solved!!!

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

tilted the dishwasher back so the bottom was exposed and unhooked the old hoses, then removed old hoses through the back side of the dish washer then fed the new hoses through the back and hooked them up.

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.

Everyone said it's too old to fix, I said I have nothing to lose by taking it apart and looking for broken parts.Sure enough I found a broken pump propeller and orded the part and had it in 18 hrs. I,with the help of a you-tube tutorial, fixed it in an hour. My wife thinks I am a hero. I think I am a hero cause I saved $500.

float was missing palnut and letting the float slide up too much causing small leak around the float

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.

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.

I googled the simptoms online, and found that the most common cause for a door leak was the door seal. I purchased the seal online from PartSelect.com. Two days later, the part arrived. I pulled out the old seal and pushed in the new one. No tools required. That fixed the problem. While looking at the parts diagram, I noticed that my dishwasher didn't have the water deflectors installed. I don't know if they were ever there. They were cheap, so I ordered them online and slid them into place in less than 10 seconds. Again, no tools required. Dishwasher runs great, no leaks.

1 - Turned off the power
2 - Loosened screws on inside door panel
3 - Removed panel (still attached by ground wire)
4 - Removed black swtich cover
5 - Removed screws holding latch assembly
6 - Dropped in new latch
7 - Pulled away plastic switch holder, carefully
8 - Examined black micro switches (Land R); noticed right switch button defective
9 - Removed wires (2) from clips on right switch
10 - Pulled out switch (holding up plastic arm)
11 - Replaced defective switch from those in dorr switch assembly (I did not replace the plastic assembly itself, since the old one was OK, but you could if you wanted to be punctilious about it.
12 - Screwed assembly back in position
13 - Put on black cover again
14 - put on inner plastic door panel
15 - Screwed panel back
16 - Ran a load of dishes - perfect!

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.
