DWC7400AAW Maytag Dishwasher - Instructions

Observed the way gasket was installed including slight overhang on each side.
I simply pulled out the old gasket, starting at one end. I then wiped down the area with a dampened rag and pressed in the new gasket exactly the way the old one came out. It is important not to stretch it, just push it into place ending up with the same overhang on both sides.
Total time less than 5 minutes with no tools.

All I had to do was to snap the parts into place. I also had someone come here to find a leak in my dishwasher. It was in the latch and seal that kept the soap dispenser closed. They wanted to charge me over $50 when the part only cost less than $9 with shipping. I just ordered it and installed it myself. Piece of cake!

Slipped into place the two wheels on lower basket that had gone missing; removed brackets for adjustable section that were broken and easily snapped knew ones into place; connected handle to flatware basket and replaced the old one. Why we didn't do this years ago!

Snapped on new wheels

I suspected that the wax motor had gone bad based on reviews I had read. The repair requires a TORX bit to remove seven screws holding the plastic cover on the inside of the door. I sat in a chair with the door resting on my knees and took the screws out. Once open, the two wax motors are under the cover and easily accessible. You simply pull the wax motors out and detach two wire plugs. You should note how the wires are attached. The wire plugs were a little difficult to pull off but with a little effort they came straight off. Once new wax motors were installed, the soap dispenser opened.

I was also using a gel dishwasher detergent and was told that, for some reason, it might have begun to act like glue and this might also have prevented the soap dispenser from opening. I switched to powder and that did not solve the problem leading me to replace the wax motors. The soap dispenser spring seems a little weak so I have continued using powder.

Ordered replacement basket online at much better price than available localy. When I recieved it discovered that it did not include the handle, but was suprised to see it labeled as "Genuine Maytag Parts" ( I realy expected a knock-off replacement part for the price difference). I was able to remove tha handle from the old basket and install it on the new one. Job done. No problem

Once I figured out how to get the endcap off the roller track (allow several minutes, because it was designed by some dork), I slipped the old roller off the track, put the new roller on, and clipped it to the rack. Then I put the track cap back on (really easy once you've figured out how to get it off) and it was good as new.

As for how the cap comes off, it's difficult to describe. But it may help you to know that the cap, despite what it looks like at first, is actually surprisingly long and folded on top of itself. Pulling it directly out doesn't work; you have to unfold it before there's any chance of getting it out.

I removed the two plates located below the dishwasher door to expose the float switch. I removed the two screws holding float switch, I removed screw holding switch actuator, then I removed float assembly.
Installed new float assembly, but could not use the float palnut, it had too small of a hole, I substituted a larger one that fit the float better. Note I fitted the palnut to the float (the nut cuts it's own threads in the float) before installing the float. This made installation easier. Next I transferred the two wires from the old float switch to the new float switch in the same positions as the existing switch wires. Then I installed the float switch. Finally, I cleaned up the float switch actuator and screw so that the actuator moves freely on the screw. I then installed the float switch actuator and ran the dishwasher to check for proper operation. Note: this float and switch control the water level in the dishwasher. If the actuator sticks, the dishwasher will fill with too much water and leak. If the float has collected dirt inside, it will weigh more and the water level will be too high, causing the dishwasher will fill with too much water and leak. If the switch sticks or fails the water level will be too high, causing the dishwasher will fill with too much water and leak. That is why I relaced the parts: float and switch. I don't want to go back and work on this again.
Lastly, after a few days of proper operation, I installed the two plates located below the dishwasher door. Job done!

1. I removed the covers below the door and watched during a wash cycle to see where the water was leaking. There was a small pinhole on the rubber connector at the end of what turned out to be the "top shower hose". I was hoping I could just replace that rubber connector, but apparently it is permanantly attached to the entire "top shower hose" assembly.
2. To remove the top shower hose I first turned of the circuit breaker to the dishwasher.
3. I needed to slide the dishwasher about half way out of the cabinet, requiring removal of two screws at the top of the dishwasher attaching it to the counter.
4. I also had to turn off the water and disconnect the water supply hose (at supply valve, not inside the washer) because it had no slack to allow the dishwasher to slide out of the cabinet.
5. I removed the hose clamp at the bottom of the dishwasher.
6. I removed the top dish rack (there are clips on the ends of the rails that can be opened to allow the rack to come out).
7. I popped off the upper washer arm by fiddling with the clip mechanism. Then I removed the threaded "nut" holding the hose in place.
8. As others mentioned, it is good to remember to save and re-use the hose clamp and rubber washer.
9. Removed the old hose.
10. Ordered new hose, waited for delivery. Kids washed dishes by hand for a few days.
11. Installed the new hose. Replaced the rubber washer at the top end and fastened with the "nut." Replaced the washer arm and top dish rack.
12. Connected the bottom end of hose, re-using the hose clamp.
13. Positioned dishwasher back under cabinet and replaced screws.
14. Re-connected the water supply hose.
15. Turned circuit breaker back on.
16. Began using dishwasher again. Observed a few wash cycles to ensure no leaks.
17. Re-attached the covers below the door.
18. Done.

snapped on new roller and job done

My first diagnosis was that the leak was originating from a worn door seal. The door seal was replaced, but did not correct the problem. The spray bars were inspected for cracks or splits and were found to be sound. I removed the interior cover of the door and traced the water leak back to the dispenser door latch seal. The latch grommet was replaced and the problem was corrected. In order to replace the grommet, the interior door cover screws were removed using a star bit screw driver. Once the door cover was separated from the door, the small motor that operates the door latch mechanism needs to be unclipped from the door cover (leave the wiring harness connected). Use a nut driver with a 1/4" socket to remove the latch mechanism (2 screws). Slide the old rubber grommet over the latch, and install the new rubber grommet. Reassemble the latch mechanism, reversing the previous steps. Done.

first i removed the 2 holding screws fron the underside of the counter then oulled the dishwasher out about a foot. i then removed the side panel that hold the front plate in plase on the right, below this were the screws that held the door hinge assembly on the right. i then proceeded to remove those bolts. and replaced with the new one. replacing the spring and the linkage came next no tools required. i have to say that the diagram when i ordered helped emensly. i am a 45 yr old woman and fixed it by nyself thanks to your ordering diagrams. life is good!!

I took off old upper spray arm by gently prying it and the retainer off the upper section of the dishwasher. When I first did this, two prongs of the original retainer clip broke off so I had to order a new retainer clip. The new arm fit perfectly in place and was easily held in place by the new retainer clip. This is a very simple and easy repair. The only tool I used was a flat headed screwdriver to pry off the old arm, but one could probably pry it off manually also.

1. Turned power to the unit off.
2. Used a star bit to remove the 7 screws holding the door panel in place.
3. Handed each to my 2 year-old grand daughter.
4. Removed a 1" switch metal retaining plate and a black plastic cover. Removed one screw holding the switch in place.
5. Gently lifted out the old switch and compared it to the replacement switch.
6. Inserted the two black connectors into the new switch.
7. Removed each of the four wires connected to the old switch and connected each, in-turn, to the new switch. Removed the exterior black handle from the old switch and snapped it into place on the new switch.
8. Put the switch into place, reinstalled the black plastic housing cover and long 1" metal switch retaining panel.
9. Set the door cover in place and let the 2 year-old screw in the 7 retaining screws.
10. Don't have to listen to the wife complain about the dishwasher anymore.
