DWC7400AAW Maytag Dishwasher - Instructions

Most all of the workable parts on a dishwasher are accessed thru the bottom. Luckily ours is portable. Took the dishwasher to the garage, flipped it on its back on my motorcycle/ATV jack. that makes it so much easier because you can raise it up 24". Used the schematic from Part Select and found the water valve. Removed two screws, two wires and two clamps and viola, water valve comes out. Installed the new one, and reassembled, I thought. I left off the hose that connects to the wash drum. Started it up and had water all over the floor immediately. Took to the garage, flipped it back over and realized what I had done. Felt like a moron. Reconnected hose like it was supposed to be and it runs great.

We simply removed the old gasket which was corroded, cleaned up the hard water buildup, and popped the new gasket into place. The problem was fixed! No more leak!

I took out both wax motors - tried switching the motors on the rinse dispenser and soap dispenser but they were both dead - new motors from partselect arrived fast - simple installation if you have the torx screwdriver for the door inner panel.

i took the dishwasher apart, took off the old hose and replace it with the new one. it was real easy. i smiled as my two yr. old tried to help me . i'm sure i'll be odering other parts in the future.

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.

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.

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.

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.

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.

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.

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.

1- turn power off. 2- remove 7 screws to take door apart 3- remove 2 screws to take dispenser out. 4- i unhooked electic plug from it. 5- replace grommet and all back together. not bad to be 72 years old.

The part arrived sooner than I was ready to install! But it only took about 30 mins.(could take less but I like to do extra) I used a cordless drill with a star bit to remove the 7 screws holding on the inside plastic door cover. I unplugged the four electrical plugs so I could take the cover off completely. Once removing the cover I placed the cover on the kitchen counter to work on. I removed the liquid softner dispenser by turning tthe big threaded white plastic gromet on the front side of cover. I checked the big o ring for wear. Before reinstalling the liquid dispenser I placed a bead on 3-M black gasket silicon around the base and placed the o-ring on top of it just to make sure that it won't leak either. (this is installed last) There was quite a bit of the calcium build all over the parts. I cleaned this up with some CLR and a toothbrush, you don't have too but I'm a little picky and do not want to open it up again.
There are 2 little hex head screws holding the latch and associated hardware in place removing them was no problem. remove the old rubber gromet and put the new one on. Make sure the area where the gromet seats is smooth and clean. Now put it all back together and you should have no leaks

I had to replace the faucet in the kitchen sink orignnally. However since I use a porteable dishwasher, its hose connects to the kitchen faucet. The new faucets aerator is threaded differently than the old so that the dishwasher adapter would not screw in. I had misplaced the adappter kit that came with the dishwasher last year, so I ordered the adapter from partselect.com. when the part came a few day it was a simple as screw out the old aerator, screwing in the new adapted and then putting the modified aerator from the old faucet back in so that the dishwasher can be connected as needed.
