MDB9979SKZ0 Maytag Dishwasher - Instructions

I called an experienced plumber, who balanced and installed my new dishwasher properly, using the brackets I ordered from Parts Select, after an INEXPERIENCED plumber had tossed the factory-provided mounting brackets out with the shipping carton. Relief!

After pulling the dishwasher out, I was able to determine the leak was occurring around the plastic nuts on the end of the heating element. I removed the heating element and saw that even though there were washers on the ends that protruded through the backside of the machine, they really weren't sealing the holes the element was sticking through. Looking at YouTube videos on the installation procedure, I noticed the element being installed had a sort of metal grommet permanently affixed to each end and the rubber washers were between the grommet and the dishwasher body. I ordered the new part and saw this to be when I received the new part. This grommet allowed the washer to seal the hole, once the plastic nuts were installed on the backside of the dishwasher. This seems to have stopped the leak. I don't know how the original part ever worked correctly, since the washers freely sat on the element with nothing to force them up against the body of the dishwasher and seal the holes. It may have been leaking long before I discovered the problem.

- Shut off power to the washer
- Removed cap on top of agitator
- First, I tried using a ratchet set to remove the bolt that is inside the agitator at the baseplate. Tub would spin when I tried this method, so I used an air impact with long extensions. One press of the impact and the bolt loosened.
- Tied a pair of shoelaces together and stuffed them inside the seam around the agitator baseplate. I put the shoelaces half way around the baseplate. Get it in the seam then with two hands, each with an end of the shoelace, pull up on the baseplate. Success!!
- Installed the new agitator with base plate and then used the ratchet set to tighten the bolt. Didn’t want to take a chance on stripping the bolt inside the agitator with the air impact when tightening.

The valve has a plastic fitting to attach the the water line with a hose fitting. Was not carful enough with the original and damaged it attaching the water line. Ordered a replacement fitting. While it is possible to replace the water inlet valve without pulling the dishwasher out from the cabinet found it was easier to get at with the machine out. The video does and good job of showing the removal and replacing the valve. Easy job, don't be like me and be careful attaching the water line.

After unplugging the dishwasher, removing the water supply hose, and disconnecting the drain hose, I removed the dishwasher from under the cabinet. I turned the dishwasher on its side, exposing the drain pump. I removed the electrical connection wire by sliding the white keeper forward and then using a small screwdriver, I pushed in on the black clip securing the plug. I then found the clip holding the pump and rotated the pump from the sump area. I installed the new pump in the same way I removed it. Reinstalled the water line, pump hose . Put unit back and plugged it in. Turned on dishwasher. Works perfectly now.

I found it best to lay the dishwasher on it's side, this makes it easier to attach a 90 degree hose fitting without cross threading the plastic fitting.

Removed old part and replaced with new part

Turn off water and disconnect water line.
Pull dishwasher out as far as possible.
loosen both door hinges, with a helper holding the door at an angle.
Disconnect connecting wire between hinges.
Remove and replace left door hinge. Then remove and replace the right hinge.
Reconnect every thing, turn on water.
Hinge is a poor design. Ours had grease on the spring and it had slipped off the connection.

Diagnose using onboard diagnostic function. Note the light code for our dishwasher did not match others online, so check the quick guide that came with your dishwasher.

Undo all clamps to the circulation pump, remove the drain pump from the assembly.

Install drain pump into new assembly, and install all parts into dishwasher. Ensure all cables connected and reinstall dishwasher into cabinet space. Run short test cycle and check for leaks.

followed directions, a kid could have done it,

Inner gasket (Part # PS16221119) was angled in at the corners, so it wouldn't make a seal with the door, resulting in steam leakage and damage to adjacent cabinet door. Simply pulled out old gasket, pushed new one into track and voila, problem solved. New gasket angles out at corners, creating steam-tight seal.

Cut DW brackets to size, attached to DW. Bent back tabs, pushed DW into place and installed screws.

Was a little time consuming as i had to disconnect water and waste supply hook ups under sink. After getting that done was really easy. Flipped DWasher in side removed old unit and installed new.

I just popped the new one onto the bottom of the middle rack and it was done. Easiest repair I have EVER done!

Went to PartsSelect. Put in Dishwasher model number. Chose the screws for that model number. Ordered the screws. Can't get any easier than that!
