DWU7400BAE Maytag Dishwasher - Instructions

Removed Torx (T20) screws around perimiter of inside cover. Lifted cover and inverted it, then disconnected the two terminals from the wax motor. Wire and motor terminals had green corrosion and entire motor/latch assembly was caked with accumulated detergent. After ensuring circuit was not hot, cleaned wire terminals by soaking ends (one a a time) in white vinegar, then water, then a spritz of WD-40. Removed old assmebly and reservoir, then thoroughly cleaned inside cover and vacuumed inside of dishwasher door. Took digital pics at each step of disassembly as a reference when reassembling.

Instructions provided with conversion kit are useless. Attached parts, motor, and gasket to new assembly first, using old assembly as a guide. then attached to cover before replacing reservoir. Inserted plunger into reservoir and twisted to secure. Installed o-ring and mounted reservoir; slot on reservoir mates with tab on assembly, and white lever arm actuates plunger. Reattached wires to motor and replaced inside cover. Ran a wash cycle and confirmed cup lid opened.

Note that my model only had one wax motor, so new assembly was identical to old and the Y-cable was not needed. As another commenter pointed out, latch assembly will not appear to work correctly manipulated by hand until you remember that cup lid holds latch at midpoint of travel at start of wash.

I removed the wash basket. I unscrewed the cover. I disassembled the spray arm. I removed the broken lower wash arm support. I installed the new one and put everything back.

Very easy.

Plus, the parts reached my desk less than 24 hours after I placed the order. Very pleased.

Front Door Panel Insert: Remove the screws located in the metal strips surrounding the panel. This releases the old panel and allowes the old panel to be replaced with the new panel. Truly a piece of cake. Access Panel Insert: may need a small wrench to get at the screws to remove the entire access panel from the dishwasher unit. Then remove the screws in the metal strip surrounding the access panel to replace the panel insert. A little more work, but still rather easy.

First of all, rather then spending the 44 dollars on the main door seal simply cut yours in halve and trim a quarter of an inch from the disintegrated ends and use superglue and glue these ends together. this glued end will now be up top and in the middle and new clean ends will be down in the corners. next I removed the plastic door panel using a torxhead screwdriver, I just stuck the new inner foam pad on the old one. Then I glued rubber washers to the inner frame about 1/8 thick in the top 2 corners only. Finally I reattached the plastic door being careful not to tighten the torx head bolts just tight enough. It's dry and working good.

First I had to unhook the electric, water line and drain hose. Then slide out the dishwasher. Took several days to find the drain hose - local stores only carried a 6 ft hose and I needed a 7 ft. Once I found it online, purchased it and recieved it I put it all back together and all is good.

Sooooooooo, I ordered a new kick plate, it arrived promptly, tried installing it and it was being difficult. Removed plate above that and lined up new plate(kick plate) tried putting plate above it on and as when we installed the machine that upper plate was difficult. Removed upper plate to fcheck problem of installation and guess what? Stuck in the inside of the upper plate was the lower plate complete with sound insulation. Happy ending :-)

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.

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.

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.

Removed the screws holding the inside panel. of door. Then, removed panel, took out 3 bolts holding the timer in place..Removed wires from timer, plugged wires into new timer, installed timer with 3 bolts, replaced inside panel, to finish the job..easy..Saved alot of money not having to buy a new dishwasher...

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

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.

After removing the parts so I could get at the o-ring, I replaced the o-ring and restarted the dishwasher. Water was still getting past. Maybe has something to do with the difficulty of tightening around the short shoulder near the o-ring. To overcome the problem I applied a thin layer of Marine Goop under and over the o-ruing and reassembled the parts. Now no leaks.

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.

I unscrewed the parts of the washing tower, then removed the housing and filters above the impeller. Lastly I removed and replaced the impeller and "o" ring. This repair went fine. Unfortunately another part (blower) let go and I decided not invest any more time or money into this machine since it was so old.
