MDC4100AWE Maytag Dishwasher - Instructions

Removed old door gasket and water deflectors and replaced with new. Got the gasket in backwards at first. Removed and rotated 180 degrees and it went in properly. (Used tech video provided by parts select to help me.)

Though the old gasket was definitely bad, water still leaked after replacement.

Key issue ...... over time, contamination has accumulated in the water shutoff lever assembly and also on the shutoff microswitch underneath the internal water float, making both sticky and non-responsive to water level. Water had been overfilling. (probably defaulting to a maximum number of seconds to fill). ALSO - original installation was not totally level, with back of tub higher than the front.

Leveled tub. Removed mocroswitch and lever and cleaned both of sticky grease.

No more leakage.. basic problem was actually overfilling, allowing water to surge into the lower internal door vent upon pump startup.

Simply remove the washer nut,then pull the float assembly. As far the lever,just unscrew the screw and replace the actuator lever. What was great about everything I was able to go to the presented diagram. This allowed me to find the exact parts I needed. Of course make sure you have the model number.

We have a nine year old Maytag dishwasher. The handle latch is plastic and over time with the many repeated uses it cracked and broke. I went to the local appliance repair shop and found the part in their data base but it would take ten days to get and cost $22.
My wife and I thought it might be time to get a new dishwasher but after checking out prices at $500 or more, I decided to search on line and repair it myself.
I found the part easily and quickly on Partselect.com and it was actually half the price of another internet dealer. The photographs helped me confirm I was buying the right part. It cost $6 plus shipping and I was amazed that it arrived in two days to California. It was easy to install, simply by removing the interior panel and slipping the new piece into place in the handle. The dishwasher works like new.
Thank you, Partselect.com for a quick answer to our problem!

I took the bottom rack out of the dishwasher. I then took the filter guard and bottom spray arm out. Then I took the screws out of the filter guard to get to the rinse arm. I took the filter guard off, took the old rinse arm out and put in the new one. Have to make sure it is completely resting inside there. Then I put the filter guard back on. Put the screws back into the filter guard, put the two arm seals down around the rinse arm, put the bottom arm spray with guard back into the notches, put the screw top on so it can screw back in and the dishwasher is ready to go. Just make sure that you don't have a lot of soap built up, it will not clean the dishes right nor will the spray arms move. I had to call my appliance person out, and I have so much built up from soap, that I had to order a new filter guard and top and bottom spray jets. I now know to switch back to powder or liquid soap, because the tablets make a huge built up of soap... I have these parts on order now. In the meantime, I am cleaning out the jets with dishwasher magic and vinegar while I am waiting for my new parts. I now know how to put things back together so when I have this happen again I will know how to do it to save me the 63.00 office call and parts. I am happy that I know where to get my parts when I need them or break them by accident on trying to put my dishwasher back together again. Thanks.

So I decided to stick in some CLR to see if it would clean it up. Well it got considerably worse. So ordered the new faucet adapter, threaded adapter and the two washers, due to not knowing what i would need. It came like unbelievably fast considering it was Christmas time. Unscrewed the old one from the faucet, screwed on the new one. hooked up the dishwasher, watched it for a bit for any leaks at the connection, and it worked great! I seem to have more water pressure too coming from the sink faucet. Thank you so much for the quickness in sending out my order! -- Scott

That's it !!!!!!!!!!!!!!!!

The repair was very involved, but from previous experience cleaning the dishwasher, it was worth not having to buy a new one. I removed all of the lower parts down to the motor shaft. That process is tricky, but if you do it methodically, and slowly, it is not too bad. The real problem wash the scum that was left behind by the soap used in the dishwasher. After removing all the parts, I ordered the parts I could not clean, and cleaned the parts I could. I figured out that the door was leaking because of the soap scum buildup on all the parts, causing the water level to raise faster than it could be pumped out. After I received the new parts, I simply put everything back together and it works better than ever now. I used the parts layout on your website to help in aiding me to put everything back correctly. I am very appreciative that I can get parts easily through your website, and not have to hire a "service technician" to come out and do the same thing, for the price of a new washer. Thanks!

I did not move the dishwasher out. It is a fairly tight space underneath, but the water inlet valve is located toward the front, so it wasn't too bad. The steps were:

1) unplug the power and turn off the water to the dishwasher.
2) remove the 2 wire connectors.
3) use the nutdriver to remove the 2 screws that hold the valve to the side of the dishwasher.
4) use a wrench (5/8") to remove the nut where the water goes into the valve. This takes some patience since you can't turn the wrench very far in the tight space.
5) remove the water outlet hose by using pliers to squeeze together the clamp and move it up the hose. Then twist the valve to free the hose and remove it from the valve. The nibs on the clamp are small and take a little time to get them squeezed together. If the hose has been on there a long time, you will have to twist the valve a few times to free it up.
6) now you will have to remove the sleeve that the nut was screwed onto. I had to take the valve to my vise to hold it. Then it wasn't too hard to remove.
7) use teflon tape before you reassemble. Just go in the reverse order.
8) hope there isn't a leak. Mine didn't.

The new water inlet valve seems to have fixed the problem!

Make sure dishwasher is powered off. Remove all inner door panel screws. Lift inner door panel upward and lean against the tub. Use a putty knife or spatula to lift old lower foam seal.

Front Door Panel was replaced by unscrewing 3 screws on each left and right side of the dishwasher.

The bottom screws did not need to be completely unscrewed, just losen it enough to be able to remove the panel out.

Replace it with the new panel and screw back in the screws.

It takes about 5 min. to disassembled the lower jet system. As you disassemble, make sure you clean all the filters, and asses the integrity of the filters. If they are broken, you need to replace. Once you get to the impeller, you know it is broken because the lower part is loose. To replace you need to firmly hold the impeller as you unscrew the top screw. If the housing gasket is broken or too loose, replace. Otherwise you will have leak. Refer to your models diagram for proper assembly.

Actual i missed diagnosed the leak and ordered a very expensive door gasket. The leak was coming from shrinage of the wax resevoire o rig and the tab seal for the soap dispensor. I missed the trees the forest got in the way. The leak was dripping alond the front panel well away from the main door seal.

I cleans a the plastic surfaces and noticed a lip around the opening for the reservoire and used 150 sandpaper to remove it. Replaced the O ring, tab seal and bothe selonoids and cleaned everything. Put it back together. Works find lasts along time

Peeled off the old foam strip, cleaned with rubbing alcohol, let dry completely, applied new foam strip,replaced door interior done I wish repairing relationships with fiance and kids were one tenth this easy.

First of all, rather then spending the 44 dollars on the main door seal simply cut yours in halve and trim a quarter of an inch from the disintegrated ends and use superglue and glue these ends together. this glued end will now be up top and in the middle and new clean ends will be down in the corners. next I removed the plastic door panel using a torxhead screwdriver, I just stuck the new inner foam pad on the old one. Then I glued rubber washers to the inner frame about 1/8 thick in the top 2 corners only. Finally I reattached the plastic door being careful not to tighten the torx head bolts just tight enough. It's dry and working good.
