DWU7400ABE Maytag Dishwasher - Instructions

Attempted repair was quick & simple. Removed 7 torx screws, and then pulled the wax motor out of its holder. Pulled 2 wires off, and replaced old motor with new motor. Reattached wires, & reassembled.
Only problem was this did not fix the problem, so back to square one, but worth a shot.

Remove the lower panel by taking out the 2 screws on top and 2 at the bottom of the panel. To diagnose the problem, verify that there is water supplied from the valve under the sink to the water supply valve under the DW. This can be done by turning off the valve under the sink, disconnecting the copper supply line under the DW then turning on the valve under the sink to see if water passes through the line.

The float switch is located on the left front (as you face the DW). This is activated by the float in the tub. Check to be certain that the float is not restricted. The contact point on the switch is a spring loaded plunger. It should depress as the float rises and pop back out as the float returns to its low point.

Turn off the circuit breaker for the DW. To remove the switch, pull off the two electric leads from the switch. Mark the top lead with a piece of tape. Then remove the one philips screw. Replace the switch by reversing the procedure. Note that you have aligned the float contact point with the float.

I first made sure the new gasket was long enough and it matched the original. Next I used the tip of a screwdriver to pick out a corner of the old gasket and then pulled the entire thing out. I noticed the old one stopped at the bottom of the gasket well. The new one was much longer and I thought I might have to cut it to length. Well I'm glad I didn't. If you start on the right side and work your way up and around with a 2 in. piece longer then what the old one was. I carefully tucked it in the bottom and closed the door. Glad I didn't cut the new one. Instructions would have been nice. Overall an easy fix. I'm very mechanically inclined so I knew better.

New pump housing filter was needed as the old one was plugged and distorted.

I

Inserted snap spray retainer through center of sprayer arm, snapped whole thing into place, and I was done!

First I replaced the door gasket as every one else. This cut drips about 30%. I then discoverd that the Rinse Aid circular dispenser cap was opened about half way. I turned the cap tightly clockwise to close and cut drips to 90% total. I czn live with the other 10%,

Removed old gasket and simply replaced it with the new one. Very easy.

I didn't know how to put in the new one clips until I looked up a picture of them in place, on-line. Once I saw the picture, it was a matter of clipping the new ones in place.

pulled out the old gasket, cleaned the area before pressing in the new gasket with my fingers ,I made sure to put it in the same way as the old one. You have no idea how happy I am that this solved the problem.

I removed the original gasket, wiped down the area, and installed the new gasket the same way the old one was installed. It was very easy.

removed old deteriorated gasket - just pulled out
cleaned soap particles from door seal area
pressd in new gasket - note orientation
done.

still leaks - will investigate further

After pulling dishwasher out both springs easily installed using plastic connectors on the bottom left and right sides. Pliars were used to stretch the springs. It took fifteen minutes at most.

I removed the inside door cover, unpluged the accuator, removed the two screws holding the dispenser latch in place. Replaced both the latch and rubber groumet. returned the door to normal operation and verified no leaks was present.

Removed door interior, confirmed with tester that power was reaching door cut-off switch, but not power on other side of switch when engaged. Noticed that little switch button frozen in shut position, assumed switch had burned out. Installer new door cut-off switch with new (dual) switch units in place, plugged in unit and it ran perfectly.

I had already removed the old racks so I could compare them to diagrams on line. I set up the replacement parts in the same way that the old racks were connected, re-using the brackets. I then installed the entire assembly, front and rear racks plus the brackets, onto the bottom dishwasher tray using the clips that were part of the brackets.
