After 22 years of virtually trouble -free service, I could tell by the sound that something was wrong. Water fill ran too long. Float not stuck. Checked and found float switch stuck.

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!!

Removed two panels on front bottom to gain access to motor and pump pulley.
Looped belt around motor pulley and partially looped belt on larger pump pulley then turned pump pulley together with the belt until belt was fully installed., then coated belt with silicone grease to lubricate it.. very simple procedure.

One n ote of precaution, UNPLUG power plug before working on appliance.

Flange was broken in several places

I removed the old flange pieces before ordering the new one, then repositioned the washer after attaching the new one to the washer top. I then attached the flange to the counter top resulting in a more stable appliance. It was simple to remove the screws and install the new flange.

Since the bimetal repair kit was not available, I bought the complete detergent cup, gasket, and bimetal switch assembly set. This was still far cheaper than paying for a professional repair. All I had to do after shutting off the power is to remove screws to open up the door (door trim/6 screws & 6 screws on the inner side of door edge s to remove outer wall of door). The detergent cup assembly is right there for easy access! I unplugged the 2 electric wire plugs to the bimetal switch (paying attention to which plug goes where for when I reassemble), removed the 6 screws that mount the cup assembly, removed assembly and gasket, cleaned the surfaces, and reassembled with the new assembly. Very, very easy to do and everything works like a charm!

Door no longer closed tight enough to prevent water leaking.

Ours is a portable with butcher top. Three screws under the front edge allow the top to be slid forward and off. Then it is obvious which screws release the old flange.

The latch hook needs to be separated from the metal strip and inserted into the front of the flange through the slot, then secured back onto the metal strip.< br />
Don't tighten it too much until you get the thing back together. Then adjust it so the door closes tightly and make it tight. If that machine screw works loose it allows the latch to move sideways which will widen the slot--not good.

It should be checked for tightness every year unless you want to replace that plastic part again. It should have been made of metal to begin with. I'm surprised Maytag would use plastic in such a part.

Not a difficult repair unless you are a total klutz with a screwdriver.

Plastic part on upper rack had broken

No tools were needed. The top rack was slid out as far as it could go (no need to remove from the dishwasher) and the utensil basket was removed. Matching the positioning of the other good clips on the upper rack, the new accessory rack pivot clips were snapped into place. The pins on each end of the accessory racks were placed into the p ivot holes provided on the clips and pressed into placed. The bottom prong on each clip was then gently pressed upward until it snapped into the groove on the bottom of the clip. The pivot action of each rack was tested. The untensil basket was put back into place and the upper rack was slid back into the dishwasher. Done!

belt was worn out

  • Very Difficult

  • Pliers, Screw drivers
I was not able to follow the instructions exactly since they called for stretching the belt around the back pulley with the left hand. For a woman that prooved too difficult so instead I attached the belt to the back pulley first and used 2 screw drivers (they are thin) to stretch the belt around the front pulley. It took considerable eff ort but I got it on!! The dishwasher now works. Praise God!!

First, let me say that the parts arrived really fast,--thnaks for the great service!

First I removed the screws inside the door edges. This releases the front door panels allowing access to the detergent cup parts. Then I removed the old cam return spring, the old cam (and the old spring underneath the cam) and the old bi-met al switch. The instructions were pretty clear on how to install the new style return spring and new cam. Then I installed the new bi-metal switch.

Really, the hardest part of the whole repair is getting the door panels back in the proper place so that the screw holes are aligned. That probably took longer than the rest of the repair job.

The new parts have the detergent cup working like new again. Very satisfying repair!

The detergent holder wouldn't spring open during the wash cycle

  • Aron from New Berlin, WI
  • Really Easy

First, I had to remove the outer face panel of the door. Four screws on the inside of the door hold the large panel onto the front. Removing these screws and the panel revealed the detergent cup assembly. There is no need to disconnect the power as long as the door latch is in the open position for this repair. I removed the two wires, bl ue and white from the leads, keeping note which was attached to which lead. I used a hex head screw driver to remove the 6 screws that hold the detergent cup in place. After removing the detergent cup and gasket, I cleaned the surfaces with a scouring pad to make sure the new gasket would have a good seal. I installed the new detergent cup with the 6 hex screws and re-attached the leads. I replaced the face panel with the four interior screws after running a couple cycles to be sure the problem was fixed, which it was.
