MDB7749SAB1 Maytag Dishwasher - Instructions

I removed the dishwasher from under the cabinet. This is what took the most time. Before removing the dishwasher from under the cabinet I disconnected the drain cable to remove all the water from unit. After removing the dishwasher I tipped the unit on its left side. The motor/pump assembly is held in with one screw. After removing this screw the pump/motor assembly comes out with a 1/8 turn counter clock wise. The replacement pump/motor assembly was put back in in reverse order. After the pump/motor assembly was replaced I replaced the door balance cable kit on the right side of the unit. Next I tipped the unit on to its right side and replace the left balance cable kit. After this all that was left was to return the unit back under the cabinet and hook up the water supply line, the drain line, and the power.

Installation was very easy. The online video was excellent and clear.
Thanks

I watched the video and this was the easiest repair ever. Took longer to disconnect and reinstall than it did to change out the pump. Highly recommended watching the video

Removed bad wheel sets using screw driver to help pry broken part loose. Then just snapped in replacement. Took less than 5 mins. Now it works great.

This kit comes with the link cords and the balance wheels. I only needed the cords. I undid the set screws under the counter edge and slid the Dishwasher out from under the counter. One of the links had a broken cord and the spring had snapped to the very back of the space and was a bit hard to find. I used the good side as a guide to see how to thread the cord correctly. I did not replace the wheels since they appeared to be in good shape and looked like they might be a bit more difficult to replace than just the cord. For a second I thought I had ordered the wrong part because the new cord's attachment point at the hinge did not look exactly like the originals but the new design worked just like the original. I did need one other person to help stretch the spring and hold the door in the best position so I could attach the cord to the hinge. It's working perfectly now and I saved the wheels in case I need them later.

Shut the power to the dishwasher off. Pulled unit out from under the counter top and raised the left hand side up for easy access. Disconnected the wiring, undid the clips, turned counter clockwise and removed. Reversed the order for installation and Connected the power. Ran several cycles successfully. Problem fixed. Burnt out water pump. Good as new if not better so far. Easy item search, Fast Shipping, Quality Part, Fair Pricing. Thank You Partselect.com

The upper spinner was laying in the top washer basket. I went online but no help was avaiable. Went to store where we purchased dishwasher and they gave me part number to order but not online I had to call to order. Part arrived in about three days. I took two screws loose on the top of dishwasher removed broke retainer to put new retainer in but I drop it into dishwasher so you have to me very careful
so I tried to order just the retainer but is not sold by it self. Had to order whole new kit. Other than that it is easy dishwasher runs like a new one.

Replace motor/pump assembly

I removed the old gasket. Cleaned the surface under the old gasket and began pressing the new gasket into place. Make sure the gasket is pressed all the way in to properly seat it in the groove. Didn't use the tube of gasket sealer and it worked perfectly no leak,

Was a cinch just watched the video whole procedure took an hr or so

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

I followed the PartSelect video to replace the feed tube assembly with spinner and the spray arm seal for the middle wash arm. Washing performance was better, but a couple weeks later the dishes on the bottom rack suddenly stopped getting clean. I decided I probably needed a new chopper assembly, which is identified by PartSelect as the cause of problem for 48% of the cases of dishes not getting clean. Before ordering the chopper assembly, however, I followed the video about how to replace the chopper assembly to determine whether the chopper assembly seemed to be worn out (the video shown at https://www.partselect.com/PS11722146-Whirlpool-W10083957V-Chopper-Assembly.htm). It was worse than I anticipated. I found the holes of the chopper assembly screen blocked by food, and the spinner in front of the screen had broken apart. In addition to finding the pieces of the broken chopper assembly, I discovered a treasure chest of debris, including about 8 pieces of broken glassware, 3 twister ties, a half-inch button, a 3/4-inch screw, and dozens of small pieces of metal. I poured water into the area and used a kitchen baster to suck out the water with all the pieces of debris, finishing the clean-up with paper towels. I ordered a new chopper assembly to replace the broken one, and the part arrived in under 48 hours. I relied on the same video to install the new chopper assembly. The only tricky challenge was getting the new chopper assembly back into place. I first tried needle nose pliers in two sizes, as recommended in the video, but what worked much better for me was using two chop sticks that were each about 1/4 inch square from top to bottom. Needle nose pliers are slanted, but the chopsticks did not vary in thickness and separated the screen from the spinner an even distance apart, making it easier to get the gear shaft on the chopper assembly to align in a straight line with the gear shaft on the pump motor. I also rotated the two gear shafts so the gears of the chopper assembly would mesh correctly with the gears of the pump motor shaft. The video cannot show that step very well because the man's hand blocks vision of how exactly to fit the chopper assembly into place. The video also fails to warn about possible debris around the chopper assembly and to explain how to clean out the debris. After finishing installing the chopper assembly my 14-year-old dishwasher cleaned my dishes as well as a new dishwasher. I spent a total of $110.24 on parts and shipping and invested a couple of hours total. The alternative would have been to spend $800 on a new dishwasher or wash dishes by hand. I am very, very happy with the outcome.

I found instructions on line when I goggled my dishwasher name and model number with the words noisy door. There were three or four good suggestions at a couple of the sites I visited. I tried applying vasoline, then silicone to the rope where it travels through the plastic guides but that just cut the sound down about 50%. My dishwasher has plastic guides that look like rollers but they don't turn, they are fixed in place. The ropes squeak as the pass over the guides. The replacement part kit has plastic guides that turn like wheels now so the rope does not drag over them and squeak. This repair could be done by me in 20 minutes or less every time now that I know what I am doing.

I removed the black bottom metal cover then turned the nuts on the adjusting (leveling) bolts to lower the front end of the dishwasher so I could pull it out of the cabinet. Once I lowered is as low as it would go I opened the door and pushed down on it which tilts the dishwasher down and you pull out on it and the top lip clears the cabinet. If your dishwasher just pulls out the first time you try these steps may not be necessary.
Once the dishwasher is out the guides and rope are down at the bottom in the front by the door. It's obvious what to do to replace them.

Remove upper tray and spray arm. Remove two screws retaining pipe for upper spray arm and overhead. Unscrew retainer on top of lower spray arm and remove. Gently rotate the upper feed pipe clockwise until pipe can be removed from lower pipe. You may then remove the lower pipe and bearing housing where the seal is. Reverse order for reassembly. I also replaced upper spray arm bushing. Very simple, remove one screw and the arm will come out.

The repair was really easy. First disconnected electricity staring with fuses and removing wires from dishwasher, then disconnected drain hose and water hose. Pulled it out and removed pump turning clockwise no need for tools and same way installed new one. Very easy
