MDC4100AWE Maytag Dishwasher - Instructions

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.

threw out the broken and put in a fantastically improved new one. very easy (would have done it sooner if I'd known it was that simple to find it online and order it) thanks

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 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.

slid the part in the groove (left side)

removed inner door panel. tested ythe Wax motor that operates the soap dispenser latch. It tested OK so I removed dispenser assembly. replaced the worn plastic parts and reinstalled the inner door panel.

Was extremely easy to remove that existing rackings(upper and lower), install the new racks and snap in the new spray tower. It now looks like we have a new dishwasher. We are hoping that it will last another 10+ years.
We will recommend your site to friends.

First I turned off the circuit breaker to dishwasher. Then removed the lower spinner and related parts. The water in the bottom needs to be sucked out with a shop vac next, because when the pump screws are removed any remaining water will drain underneath onto the floor. Remove the wash pump and drain rotor.
Remove the front bottom plate to access underneath, unplug the electric motor and thermister. Unscrew both hoses,drain and upper wash arm. Move the locking ring to release the the entire assembly up into the dishwasher.
The kit I bought had most of all the washer parts included, so on reassembly I used the new ones. The rest when back together in reverse order after a good cleaning. Since the thing was apart anyway why not clean up all the filters on reassembly. The kit also came with complete instructions.

It was difficult to use the guide provided online to determine what position to place the spring in. Finally I realized that the spring had to be placed with the tip that sticks out against the wall of the dishwasher to make the spring action work. The long and short pins were not a problem. How to place the spring was the main problem, but I finally figured it out. I did not need any special tools to accomplish this. I just used a kitchen knife to push the short pin into place.

Myscanning other reviews i saw mention dishwahser developed a small leak on RHS of door. I assumed the door gasket and planned to order that. On of the dispenser gromet which is only a $5 part so ordered that as well. I first replaced the door gasket which is an easy 10 mins job and ran the dishwasher again, but it still leaked.

I then removed the 7 torx screws on the door panel which came away easily. It was obvious that water was in there, so i removed the two screw on the dispenser with a nutdriver to replace the grommet. This process took 20-30 mins. After reassembly the leak was gone.

Without the comments on the website i would never have thought of the disepenser as source of the problem.

Remove bottom rack. Unscrew the retaining ring on the wash arm, remove along with wash nozzle. Unscrew the eight retaining screws on the filter cover and remove (be carefull not to lose the two plastic bushings). Pick off and set aside the wash fan. Remove the six retaining bolts on the discharge housing. Pull up and remove the discharge housing. Remove the gasket (buy a new one, cheap and easier) with small screwdriver. Push gasket into new assembly. Under plastic nut with pliers and take off the plastic bushing that the wash arm rides on. Install new housing assembly with the parts that was taken off in the reverse order. Be carfull when installing the filter cover to make sure the drain outlet is aligned or mated to drain. Gently push down until the filter in down and continue reassembly.


(PS: Never use Sears parts, they extrembly slow as well unable to deliver on time).
Wash your dishes

I took apart the lower spray arm apart and removed the 6 hex screws. I noticed that the little plastic circle thing had been ripped off the dome-shaped thing. I replaced the part and put it all back together.

Removed the inner door panel-Removed the black cowling covering the timer and wires.
Removed the swicth assembly and installed new part.
Reassembled dishwasher.

I checked the operation of the two switches. One switch did not click, when button was pushed, as cleanly as the other. There was a bit of delay and play in the button when depressed, even sticking a bit.

I used a torx driver to remove the seven screws holding the inside door panel in place. Flipping it over exposed the dispenser mechanism. There were two hex nut screws holding the whole assembly in place and two wires attached to the wax motor. As an afterthought I had ordered the sealing grommet for the latch, and as it turned out, the main problem with the sticking latch was that the grommet had worn out and allowed the hard soapy water to leak into the slider assembly and build up a hard crusty residue that had helped to ware out the old wax motor. After completely disassembling all of the parts, I scrubbed the residue out of the housing, replaced the slider, latch, spring, and grommet. Next I snapped the new wax motor into place and connected the two wires. The whole thing went back in place and the two hex screws went back to hold it all together. Finally, the seven torx screws went back to put the door back together. The whole repair went without a hitch.

First unplug the unit. Open door. Take a special tool to remove all the screws (star shaped) around the edge of the door, and remove plastic panel where motor for detergent cup sits. Remove wires (two) from the motor. Remove wax motor by unsnapping motor from its cradle--comes out by moving the fingers holding it in. Push new motor into position, being sure the round pin sticking out at the end (on the left side) so that it sits in the groove made for it. Replace panel and screws, plug power cable back into its box. Close detergent cup door, turm on dishwasher, run through cycle, open door and check to see if detergent door opened up. If it did, then fill with dishes and wash.
