DWU7400ABE Maytag Dishwasher - Instructions

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 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.

It was difficult to use the guide provided online to determine what position to place the spring in. Finally I realized that the spring had to be placed with the tip that sticks out against the wall of the dishwasher to make the spring action work. The long and short pins were not a problem. How to place the spring was the main problem, but I finally figured it out. I did not need any special tools to accomplish this. I just used a kitchen knife to push the short pin into place.

Removed the inner door panel-Removed the black cowling covering the timer and wires.
Removed the swicth assembly and installed new part.
Reassembled dishwasher.

I checked the operation of the two switches. One switch did not click, when button was pushed, as cleanly as the other. There was a bit of delay and play in the button when depressed, even sticking a bit.

We are planning on selling our home and trying to spruce it up a little. We have an old dishwasher - probably 18 years old and it works just fine but the front panel was banged up and scratched. We were actually planning to buy a new dishwasher because it looked so bad until I found out you could order a replacement for the front panel. It was a great and less expensive alternative to buying a new dishwasher. Easy to order and the part got to me in just a few days. Thanks very much.

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.

After checking this site for any clues I saw that others had the same problem and changed the door switch so I thought I would give it a shot.I removed the inner part of the door(plastic).It had about 8 screws.Then there was a plastic cover that covers the wiring that comes right out and there was the switch.There are really 2 switches that come with the latch.then take out one screw with the nut driver.Take the four wires off the old latch and install on the new latch.Then screw back into the door and put inside part of the door together.Close the door and turn on and away you go.I also turned off the power to play it safe.I was thinking of replacing the dishwasher cause it is 10 years old but now I can take my time and wait for a good deal.Thank you very much partselect.Also I ordered the part 12.00 Sunday nite and recieved it on Tuesday afternoon with no special shipping.Wow!

The replacement part was the perfect size but the threading on the terminal ends was increases to 1/2" v the 7/16" from the previous element. My first attempt was to find a similar type of part at the local hardware store(not a superstore)since I planned to replace the grommets anyway. After not having any success, I came home and modified the fasteners by slowly drilling out the id of the fasteners until they threaded properly. The time to replace after the drill out was less than 10 min and the ~$45.00 is significantly less than $450.00 for a new unit.
If I would ask anything of part select, it would be to include fastening hardware as re-engineering of products is a continual process.

I used the parts blowup diagram on PartSelect.com and dissasembled the bottom wash assembly. Carefully examining how the washer arm rotated, I determined that the spray arm support nut had broken. The extended top of it has broken off. This nut, when tightened, allows the spray arm to rotate freely. In trying to diagnose the problem, I had even removed the motor assembly at the very bottom. When I reassembled it, I apparently did not seat the gasket well and did not tighten the bolts well, so when I tested the washer, water leaked out the bottom. So, I had to dissasemble it all again and properly torque the bolts. So, I really created another problem during the diagnosis.

Piece of cake. I panicked for a minute before I realized that there was a threaded brass 90 in the inlet valve. It looked like it was the wrong part for a minute. Once I got the 90 reinstalled in the new valve, I had it back together in 10 minutes. It seems to be working better.

First, I searched the repair help on this site to see what others did to repair their diswashers, and it looked easy, so I just followed the same instructions. First, I used a hex star key wrench to remove the screws that hold in the interior door cover. I disconnected the leads to the defective wax motor, reconnected the leads to the new motor and screwed the door back together. It took 15-20 minutes and was a piece of cake! My first appliance repair, and as a single woman and first-time homeowner, I was really impressed with this site! It gave me confidence to tackle more home repairs instead of calling for service and getting raked over the coals.

First unplug the unit. Open door. Take a special tool to remove all the screws (star shaped) around the edge of the door, and remove plastic panel where motor for detergent cup sits. Remove wires (two) from the motor. Remove wax motor by unsnapping motor from its cradle--comes out by moving the fingers holding it in. Push new motor into position, being sure the round pin sticking out at the end (on the left side) so that it sits in the groove made for it. Replace panel and screws, plug power cable back into its box. Close detergent cup door, turm on dishwasher, run through cycle, open door and check to see if detergent door opened up. If it did, then fill with dishes and wash.

I took off the front bottom panel for an easy access. The valve is located on the left. Shut off water to the dishwasher. Remove the bracket that holds the valve. Remove hoses and 2 wires on the valve switch. Install new valve by revesing the steps above.

Removed timer by removing 3 screws unplugged the wiring harness and replaced timer with new one. reinstalled screws and plugged in the wiring harness.
Found a leak at the soap dispenser trip.
Ordered a new wax motor actuator, installed it but found that the soap dispenser is still not working.
