MDB7759SAB4 Maytag Dishwasher - Instructions

all 4 wheel units needed to be replaced, popped them off and installed need wheel units in roughly 10 minutes, no tools needed.

When the top rack stopped cleaning, I tracked down the problem to the food shredder/chopping blade, and then to the impeller that drives the blade. The knob on the impeller had sheared/broken off. That meant removing the motor, and replacing the impeller. Four hours, a band-aid, and a trip to Home Depot later, here are my suggestions

1. Look for videos – this site is awesome, but they don’t have a video on this particular repair. I found 4 that got me close to knowing what I was doing.
2. Do all the “remove internal stuff” - you had to anyway to find the issue with the shredder/cutting blade
3. Take pictures as you move along, you’ll need them when you have to remember the placement of the water line, drainage hose, wired connections etc.
4. You need a 1/4 inch socket set. A 3/8 drive will NOT work (it won’t fit between the shroud and the base). Don’t start working on the repair, unless you have a 1/4 in socket with about a 6" extension
5. Someone at Kitchenaid should be shot for having the waterline connection facing the back of the unit. Use a short adjustable wrench
6. The order comes with a washer, but when you take the impeller off this model, you’ll see you don’t need it.
7. Placement is everything – there was zero clearance between the bottom of the unit and the floor. Placement of the water line, drain hose, and power line was critical – had to re-position the unit about 7 times to get it to “play nice”.
8. Hindsight – only needed to remove the wire harness for the motor (take pictures)
9. Hindsight – gloves are a great idea – sheet metal is unforgiving

I removed the dishwasher from under the counter. This took the bulk of the repair time along with disconnecting the water supply and electrical connection. I had enough slack in drain hoses that I could turn the dishwasher over to replace the motor. I was surprised that there was only one bolt that held the motor in place. I put the motor on, turned the dishwasher upright and slide it back unde the counter and began the long process ofreconnecting everything. I am sureit could have gone faster if I were younger and did not need glasses for close work. Start to finish took me four hours. This was the fourth time I have replaced motors in dishwashers of various makes.

Removed old gasket, cleaned track thoroughly, then followed instructions from video on Part Select order form. Instructions very clear and precise. Getting the new gasket was a little tedious at the corners but take your time and work the gasket with your fingers as shown on the video.

1.Check the lines for any obstruction. Gunk can easily build up. I have used the dishwasher for approx. 10 years. I do rinse/scrap dishes prior to loading.
2. Drain all remaining water.
3. Unplug the dishwasher.
4. Grab a towel and proper screw driver. Unscrew the bottom protective plate. Remove the insulation plate.
5. The drain pump is located to the bottom left. Have your towel under it. Unplug it gently. Turn counter clockwise to remove.
6. Install the new drain pump (reverse order)
7. Return the insulation plate. Screw back the bottom protective plate.
8. Plug in

Following a utube video made it easy. Removed the outer cover of the door to expose latch. Two screws remove the latch, pay attention to how it was positioned and put the new one on and then replace the panel. But first turn off the electricity to the unit at the fuse box.

followed video instruction

I am a 61 year old woman and it took me a total of 2 min. max. Popped it into place and pushed in button that holds it..Taa Daa...perfect!

Unplug dishwasher and slide it out from under cabinet. Remove old broken link (a heavy string between two plastic parts) and replace with new one. Slide dishwasher back and plug it in. Very easy and no tools required.

I did not relize that the drain hose was in two parts. Naturally I ordered the wrong half. So after I relized my mistake, I re-ordered the correct part. Once the correct part was received the repair was easy and went well.

put new hose on, very easy.

Removed required hardware and dishwasher from undercounter mount. Turned dishwasher on its front and removed the old motor. Installed the new motor and tested for function. Installed once test was successful.

I took the unit apart to find out what was making the loud noise and found the seal on the main pump had been leaking ito the bearing on the motor.

Remove the mounting screws that hold the dishwasher under the counter top. Remove dust cover plates at the bottom of the machine. The machine will have to be pulled out, so turn off the water to the machine. Usually under the kitchen sink. Disconnect water supply and push it out of the way so the dishwasher can be pulled out. Pull machine out enough so you have access to the door cables and springs. The door will have to be in the closed(up) position to do the repair. Usually only one side is broken. Start with the broken side and copy the working side when installing new parts. Then repair the working side. To get the working side apart just pull on the spring and disconnect it from the cable. Do the reverse to reinstall.

Remove 2 screws on lower baseplate. Remove 2 screws that hold dishwasher inside cabinet( may be attached to counter top or side cabinets). Turn off water supply to dishwasher. Remove any connections such as water supply, electrical connection, or waste water line that prevent dishwasher from being pulled out about 3/4 of the way. With the dishwasher door closed, remove broken parts and replace with new parts. Pull on spring to make final connection of nylon cable. Reverse the above instructions for re-installing the machine.
