DU1000CGB1 Whirlpool Dishwasher - Instructions

The old gasket came out easily, but had calcium deposits in area. I cleaned the area with vinegar and water and waited until it was completely dry. The new gasket went in very easily and looked great. I started the dishwasher and alas, it still leaks, so the problem was apparently not with the gasket, but some other area. But the gasket is nice and new. Any suggestions on next step0 in troubleshooting?

i took off the kick plate and found the water valve. its the piece that water comes to from under the sink to connect to the dishwaser. it has a plug with 2 wires. i turned off the water supply, disconnected the wires(probably should have flipped the breaker but didnt) took out the 5/16 mounting screws, had to use a little end wrench on 1 because it was behind the water line and a nut driver on the other. i put some thread gook on the connection and put the new one in the way it was and it works great. i am writing this because thats where i got the info to diagnose in the first place and saved me $$$!

Plastic parts on this Kitchenaid dishwasher suffer repeat wear problems from heat and chemical detergents. The retainer nut on the bottom wash arm split horizontally int the thread area, and during operation, the wash arm would rise up and hit the bottom of the lower basket so there was a worn groove in the wing on top of the nut and the dishes weren't getting very clean. Simple replacement, just screw the nut down. Also decided to replace the bearing ring right under the wash arm because it was getting pasted with white crust-like material from hard water and chemical detergent residues. I've dealt with PartSelect twice now, and they are fast and efficient. The online parts breakdowns are easy to follow.

Installed the new upper spray arm mount. First I installed it backwards which made the blades not turn freely (rub against top rack basket). Turned it around and was good to go. I found it helpful to remove the top basket in order to do this. Note that this clip is gray while your dishwasher tines are white. This does not cause any harm.

Removed upper basket and installed the arm. New snap in didn't require phillips screwdriver as old one and new support had split to insert. Replacing upper spray spinner dropped screw down around pump. This caused misery unassembling lower covers to receive Stainless
Steel, so magnet won't help ended up with mirror and hemistat to reach through large screen figures. So make sure to put towel or something in the bottom to catch parts.

unscrewed sprayarm, removed bearing and seal, used PartSelect pic and description schematic to identify part numbers then placed order. Parts arrived in two or three days.

Removed the rest of the broken retainer plug. Part number was on the top of the plug. Went to Partselect.com looked up the part and ordered it. The right part (important) arrived in a few days. I put the arm back in place, screwed in the new retainer plug and we were back in business. Cost of part about $5.00. Price of not having to share in cleaning the dishes, priceless. Any future problems with any of my appliances, this is the first place I'll look for the needed part.

Pretty simple. Hardest part was working the end clips of the slide to remove top rack. You simply need to squeeze the plastic clip in to slide it out. Once the top rack is out, it was an obvious philips head screw removal and new part replacement.

1-remove upper rack by removing holding clips.

2-remove old assembly from Rack

3-cut old ring guide to accomodate new style (one solid plastic piece) and reglue after accomodating new assembly

4-re-install upper rack

DONE

actually my wife did the repair. she unsrewed the water sprayer and removed it, then unscrewd the star key screws and then replaced the seal. she put everything back the way it was and it is now ready to use and we no longer have the problem.
just a suggestion...if you take some baking soda and some vinager you can clean the drain out. just simply poor in the soda and then the vinager.and it will fiz cleaning your drain.

first I removed lower basket. then removed lower sprayer attached to pump housing by unscrewing the cap by hand. the I removed the pump cover . there were six alan screw two of them were missing causing the failure of the seal spraying solution at the door. replaced the pumpseal working backwards until everthing was replaced.

Removed one screw to get the spray arm off the rack, one other screw to disassembly the spray arm assembly. Replaced worn and damaged parts. Installation was reverse order of disassembly.

I removed the screws on the door cover and snapped in the new clip

for the arm I just removed one screw and replaced the arm

I was hesitant at buying the Matag made replacement, especially since it was one piece as compared to my 10-year old 3 piece assembly, and my dishwasher is KitchenAid.
Ordered on a Sunday afternoon, had in hand Tuesday same week, one phillips head screwdriver to remove/replace. Everyone smiling!
Did not need to remove upper rack. Simply unscrewed 1 screw, put on new one-piece arm, replaced with same screw.
15 minutes!
Good price/delivery.

Replaced the middle spray arm kit and the upper spray arm mount. Also replaced worn out spring for the soap dish.
Now all areas of the dishwasher get cleaned and the soap dispenses correctly every time.
