MDB7100AWS Maytag Dishwasher - Instructions

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 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.

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. Make sure door seal area is clean. Start at one end, butt new foam against the side of door and slowly pull glue strip backing while pressing foam down from left to right. Reverse door assembly.

Make sure dishwasher if off and door unlatched. Remove lower kick panel 4 screws and remove 1 screw securing float switch arm. Hold float stem with pliers and remove bottom stem nut. Remove float and re-install the new float with reverse procedure listed.
Super fast shipping on items!! Great service.

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

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.

Located circuit breaker for dishwasher and turned off breaker to secure power going to unit. Removed water spray bar arm inside dishwasher basin by unscrewing center nut and unclipping tabs against arm. Removed sheet metal access panels on bottom front of unit. Removed two individual plug in wires to temperature thermister. Removed 4 conductor plug wiring going to motor. Removed ground wire going to motor frame. Located plastic handle which cam locks motor / pump assembly into place. Pulled handle down gently to unlock from detent and turned clockwise to release pressure on assembly. Removed motor / pump assembly from dishwasher enclosure. Installed all new parts purchased as listed above utilizing parts breakdown aquired from PartSelect.com. Reinstalled motor / pump assembly in reverse order as listed above. Tested and ran unit with no problems. Thank You PartSelect.com, Robert.

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.

Open the door all the way. Remove the 7 screws along the perimeter with a Torx screwdriver. Then close the door. Remove the two screws at the bottom of the side of the outside of door panel with a phillips. With the palms of your hand flat on the panel slide the panel up about 1/2 inch and it falls toward you. Follow these steps in the opposite direction to install the new door. I did however replace the two phillips screws last.

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.

Took off the float, the jam nut was hard to get off, we ended up breaking the bottom piece of the float to get it off, but that was okay because we had a new float. The new float went on real easy and the jam nut went back on real easy. The foam insulation strip was real easy to get off we got a good hold of one end and striped it off slowly so there was nothing left on the door, then we cleaned the surface and put on the new insulation strip. We ran dishwasher to test it and there was no leak. Awesome. Cheap and easy to repair. We were impressed.

I aligned the V-shaped tabs on the inner side of the part with the slots in the mating part and simply pulled the old part out (it was already disengaged from the wheels in the metal rail). I then inserted the new part into the slots. One side went in well, but the other side required the part to be bowed slightly to match up the V-shaped tab with the slot. Then the hard part was getting the wheels in position to snap them on. Once in position, it took a bit of effort to engage the snaps in each wheel. I was afraid of breaking the new part. These snaps are very stiff and even with the notch between them there isn't any give, but I was able to apply enough constant, steady pressure to finally get them to snap in without breaking.

I replaced the door latch grommet just as everyone else has described on this site. It was pretty easy. I was amazed that such a little piece of rubber can let so much water get by. The inlet valve was not too bad either. Take the two bolts out that hold the bracket to the dishwasher. Remove the rubber hose on the back side and take loose the two electrical connections. My water line was long enough to pull it out in front of the dishwasher. Then I took the water line loose and removed the fitting. Installed the new one in reverse order of what I just described. These items took care of the bulk of the leaking problem. But I am in the process of ordering a new door seal which I hope resolves the rest of the issue. Also make sure you check the upper and lower control arms to make sure the spray holes are free of debris. This dishwasher was full of pieces of clear plastic that caused the spray arms to spray indirectly and towards the cracks of the doors.

Removed four screws on bottom plate. Located repair site on outside of cabinet. Had to hook spring on bottom rear plate by brail. Then attached linkage to spring and ran stiff wire through linkage to raise it above arm. Called a man with stronger but larger hands had him stretch the spring while I guided linkage over arm and into the slot using the wire. Removed stiff wire with needle nose pliers and reassembled front plate.
