MDC4000AWE Maytag Dishwasher - Instructions

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.

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.

Since the sprayer arm had so graciously landed on my clean glasses, there was little prep involved. After cutting the power at the box, I took a towel and cleaned some crystallized 'gunk' from around the area. Following the diagram from PartSelect for the model, I inserted the plastic clip and 'popped' the arm into place in the top of the dishwasher. It was embarassingly simple, and I'm so glad I was able to fix the beast for $20 or less.

Simply had to replace the clips in the correct position. Would have been a five minute job if I had noticed which way around the old parts went before removing them from the dishwasher to find replacements. It's amazing hoe many permutations there were before it all fit together perfectly.

The repair was very easy. The door gasket was a little short, but I gently streched it to the proper length. I replaced the other parts as a precaution as some others said they were really the source of the original leak. It went very smoothy and NO MORE LEAKS.

We had tried to use dish washer cleaners, and they would work for a time, but we started spending more money on cleaner than we wanted. I ordered and then I replaced the lower spray arm. It took a little effort to get the top screw off, due to hard water deposits. The new one went on very easily, just screwed right in like the old one. It's working great and I really don't mind not getting a new one or paying for a service call!!!

Once I removed the inside panel from the door replacing the switch was pretty simple. completed the job in less than twenty minutes.

This was the third appliance I have repaired with the help of Parts Select in the last three months.

i removed the bottom spindle inside of the washer compartment. laid the pieces out in order of which they were removed. found the impeller was busted where it attaches to the shaft of the motor. screw was missing but found it laying in the bottom (there is a screen that filters the water as it drains). replaced impeller and put parts back together in order. good as new.

First I replaced the soap door grommet -- door still leaked. Then I went for the really expensive part ($40) -- the door gasket. The old one came right out and the new one went right in -- 15 minutes tops -- and the door no longer leaked.

Thanks to all the previous posters for their hints.

Removed covers on the bottom of dishwasher so I could get access to area. Measured no voltage on water inlet pump. removed to wires from foat switch, one screw to remove float switch. When I pressed the float switch button to activate the switch would not move. Ordered and replaced the switch. 30 minutes tops

My husband does all the repair work himself so he tore it all apart but it's hard to find parts for a 23 year old machine. A store about an hour from our house said they had the part. When we got there it was the wrong impeller and it was going to be $30 to order it in. I got home on that Weds. nite ordered it and had the part 2 days later on that Friday.My husband had the part in and the dishwasher running within 20 minutes. Thrilled with the fast service from you and my husband :)

easy repair. The foam has to go over some wires but if you stretch it alittle as you place it all goes well

Purchased and installed new faucet attachment. It arrived quickly and very easy to attach. Thank you !

Unscrewed bottom panel. I could see right spring in proper position, left spring lying on floor, and broken linkage. Ordered part from partselect.com. To install, had to unscrew dishwasher attachment to counter, loosen leveling legs, pull it out a bit, then could replace linkage and reattach spring, retighten leveling legs, then push back in and replace screws and bottom panel.

Very simple. Remove bottom panels. Remove one screw holding old switch in place. Move wire connections from old switch to new one. Cleaned and lubed the switch actuator. Mounted new switch. Checked that float and actuator worked freely. Left bottom panels off till I ran a load - just to be sure all was OK. Remount bottom panels...Done! P.S. Don't forget to turn power off to dishwasher any time you work on it!!
