On Thanksgiving weekend my poor 23 -year -old Maytag dishwasher started making a horrible grinding noise and wasn't cleaning anything. I washed more dishes by hand in 4 days than I have in the past 4 years.
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 :)

Dishwasher door was slamming down, heavy to close
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.

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.

Leaking water at bottom left of dishwasher door
Initially thought this issue was the dishwasher door gasket, but after reading post on this site about door latch grommet, removed 7 "hex screws" pulled inside of dishwasher door away and traced water from leak back to soap dispenser latch/grommet area so instead of ordering door gasket ordered door latch and grommet. Replaced grommet only (in addition to 7 "hex screws" had to remove 2 additional screws to get to it) which took some maneuvering. Re-aligned grommet and latch, inserted and tightened all screws that had been removed. Works great - no more water leaking!

water wouldnt pump / making grinding noise
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.

Dishwaser Leaked onto the floor
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.

wheel broke on rack adjuster assembly on top rack
Removed the top rack and unscrewed the six screws involved on the rack adjuster. (Take note on how you took the thumb adjuster on top off for easier reassembly) Replace assembly on rack and slide rack back into dish washer. Kudos to PartSelect for getting my part here in less than 24 hours on a normal delivery charge.

Door leaked from lower right corner
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.

Dishwasher would not fill with water
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.

Dispenser door would not open
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.

Adjustable rack had broken
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.
