MDB4000AWW Maytag Dishwasher - Instructions

After removing parts, cleaned both upper and lower spray arms, blew out lead to the upper arm, and started to install the new parts.

Unfortunately, the Pump Housing Filter was still cold (freezing weather during shipment and left at the front door) and when I started to bend it into shape it broke in two places. So I tolk the old filter and some Lime away and slowly cleaned it with soft brush to open 95% of the holes.
Once ready it was installed along with the other new parts and the dishwasher works very well.

Simple homeowner repair.

Diagnosed potential problem from scematic diagram found at Parts Select .Com by entering model #. It was very likely the inlet water solenoid. Tear down was simple: Turn off water, disconnect water lines to and from solenoid, disconnect two electric terminals and remove part by removing two screws from dishwasher chasis. Before you buy the new solenoid, unscrew the water inlet elbow from solenoid and check the filter/screen inside the solenoid to make sure it isn't clogged. Assuming it's not, order the replacement part and reinstall in reverse order. Be sure to use plumber's tape on screw connections to make sure there are no leaks..... Also for ease of acces, you'll need to turn the dishwaher down on it's front. Put towels down to cushion the front and keep the controls from contact with the floor. Good luck!!

With a straight edge screwdriver I carefully removed the plastic end caps on the rack support glider-shelves, replaced the old rack with the new rack, and then reattached the end caps.

I felt better about ordering the part Online after having talked to a sales person since there were several racks from which to choose. She reassured me that I was ordering the correct part number. I am a woman and 62 years of age, and I was pretty sure this installation would be a no-brainer. I just wanted to make sure I had the right part for the job.

1) turned off power to dishwasher
2) removed each piece of pump assembly (one at a time) from inside the dishwasher. I had no repair manual and didn't know that by rotating the lock lever under the dishwasher, I could have easily removed the entire pump assembly as a unit.
3) Reassmebled the pump assembly using new parts and installed in dishwasher.
4) Reconnected hoses and electrical connection
5) Turned power back on
6) Washed dishes... it's as good as new!!!!

Removed two lower panels using nutdriver. Ran washer through a rinse cycle, to determine for sure where leak was coming from (under door on left). Examined the door gasket and observed buildup of lime deposits and a general depression of the gasket through years of use, especially in lower portions. Removed the old gasket observing how installed. Cleaned out groove with Lime-away and toothbrush. Washed clean using water in a squirt bottle. Dried things out using paper towels, and then pressed new gasket into place, starting at lower left. Readjusted the gasket to fit precisely end to end. Shut door and ran a drip free load.

I first changed the dispenser door latch grommet, which was very eazy except for the left side nut screw which was a little awkwaed to get to with the nut driver. Not a big problem but difficult enough that i stripped the threads (plastic) and had to get a larger screw which is working fine so far. Since the grommet didn't stop the leaking although it was obvious it was leaking from the soap trail. I ordered the gasket and got it very promptly put it on and guess what. Still leaked some. I discovered when they installed the dishwasher the door appeared to be warped. To fix this there are two door tension springs under the bottom panel. By adjusting these with a log screw driver problem finally solved.
It is good to have not only a great place to get parts but the idea's from others are terrific. Although this washer is 15 years old it looks new and now acts new. Thanks so much for good service and advise.

First replaced rubber seal around door, which did not stop the leaking.
Then ordered insulation foam strip and replaced old one, which fixed problem. Put new strip over the old one because tub was slightly warped.
Very pleased with order speed and cost.

removed clamps with screwdriver from bottom of dishwasher and clamp from sink drain. I taped the new hose to the old one and pulled it through. worked perfect.

First I installed the spray diverter,then I installed the discharge housing nut and tightened it down. Last I snapped on the spray diverter cap.

I had to remove the screws around the door frame and remove the side panels that attached the inside cover from the interior of the door. Once I removed it I could then unscrew the top cover that then allowed me to remove an inside cover for the internal electrical connections and the door latch was then open for repair. The electrical connections to both sides of the door switch and holder assemby had to be pulled from the assembly and I was then able to remove the assembly and the door latch. The new door holder and latch handle had to be connected to the electrical wires and inserted back into the door and the initial process was reversed to reinstall.

Very easy to do. Used needle nose pliers just to get a first grip on the door gasket and then pulled it completely out. Pulled up the Water Deflectors by hand. Cleaned the gasket trough with a soft cloth, warm water and dishwashing detergent. Rinsed. Then simply pushed the gasket into the trough, lightly tapping into place, then pushed on the water deflectors, and no more leak!

Took off bottom plate for access. Slid part that holds bottom of spring forward so I could reach it without pulling dishwasher out of position. Hooked spring to bottom attachment, then connected door spring linkage to holder that is attached to the dishwasher frame. Adjusted the tension with the tension screw and buttoned up bottom plate.

Removed the old gasket, without tools, and fit the new gasket into the space, making sure it was in the groove correctly all around, job done, works great. The ordering of the gasket on this site was easy and the shipping time was amazing, one day. Would use this company again, and recommend to anyone needing parts that wants to do repairs themself. I am sure saved a whole lot over hiring someone, and got the job done sooner also.

I removed the dishwasher to outside the house and examined it for signs of leakage. Found 2, one at the water injector and a second at the bottom right of the front door. In checking the water injector I found that a large roach had crawled in and died which was blocking the inlet into the dishwasher. I cleaned that out. I examined the door and seal but could not find any obvious source for the door leak. I purchased locally a door seal and installed it. I connected the dishwasher up to water and electricity using a grounded plug. I also hooked up a drain hose (be sure to put an elevated loop in it to keep the water from draining before being pumped out). I ran the dishwasher and found water still dripping from inside the front door during the wash cycle only. After unplugging the dishwasher, I removed the door's front decorative panel (2 screws, one on each outside lower edge) and began watching through one of the 1.5" holes punched in the door metal panel. I noted that during the wash cycle only, water was dripping from the area of the soap dispensor release mechanism. I the inner door plastic panel, by removing the seven screws. I also had to remove the dispensor release actuator since I could not pull the 2 wire connectors off without fearing I would break the mounting tabs off. I released the tabs that held in the actuator easily with my fingers freeing the actuator from the inner plastic panel. The only place that I could see an opening was the the release arm and its rubber seal. However the rubber seal was heavily caked with hardened detergent. Feeling that the seal rubber was probably hardened and cracked, I released it. I had to remove the release arm assembly held in with 2 screws. I reassembled the assembly with the new seal in and ran the dishwasher. No leaks. I did find that if I had just pulled the seal and rubbed it between my fingers the dried detergent would break off and the rubber itself was fine. Should have tried that first. I did replace the dispensor door because of crusted detergent on the door seal. I could not get the crusty stuff off without tearing the seal. I used a small thin punch to push the hinge pin (non spring side) from the plastic inner panel to the dispensor door side releasing the hinge and allowing the door to come out. Reinstalled the pins and spring into the new door. After putting the dispensor door in place, I pushed the hinge pin (non spring side) through the door hinge into the inner plastic panel.
I also wanted to improve the cleaning level that had decreased over the years. I removed the uppper pump housing by removing the hand nut on the lower spray bar then the 6 T-20 torx screws. Inside the plastic filter screen. I found that the screen was partially plugged by either minerals or dried detergent. The old one was stuck slightly to the lower pump housing. I tried to poke out the debris out of each of the screen holes but was taking way too long. I did not try chemicals but since I was ordering parts made sense to have a new one shipped in. You have to snap the new screen together and align the edges before inserting it into the lower pump housing. Reassemble the upper pump housing. Be sure to clean the filter spinning arms of debris along with the lower (and upper) spray arms befrore reassembling them. Ran the dishwasher a couple of full cycles to check for leaks and found none.
FYI, the dishwasher will not clean as well if you fill it with cold water and even with the heat element, the cycles take a very long time to run through to allow for heating the water. Once I reinstalled the dishwasher, I notice an improvement in cleaning.
Good luck.

After replacing the door gasket and seeing that this wasn't the problem, using the schematics found at partselect.com I finally realized that it may be the insulation foam strip. I ordered the product and received it very quickly. Installation went fairly quickly. It was easy to remove the old foam strip and install the new one. The only problem was that the foam strip was about 1/4 " too short and it didn't cover the entire bottom. I improvised a little bit and cut off some of the old strip and covered the gap. So far the leak seems to have been fixed. In addition to the foam strip I had to buy a torx screwdriver for $11 at the local hardware store. The total spent was around $25.
