DU1000CGZ1 Whirlpool Dishwasher - Instructions

The part arrived the next day after order was placed. That is an amazing service.
When it arrived I noticed that the new part was re-designed but the dimensions appeared to be identical. Initially it was difficult to snap it in to position but with help of a screw driver it finally snapped in place. After re-installation of the upper wash arm all looked perfect. But the arm would not spin freely. It would bind against the bottom of the upper tray. Finally after about 20 minutes I noticed that the mount was slightly slanted to one side. This was not immediately apparent unless you look carefully. Further I noticed that the bottom of the upper tray was protruding lower on the right side. Finally I realized why the mount was slanted to one side. I removed the mount and turned it 180 deg.. Bingo all fits and works perfectly. I could have avoided the problems if an orientation directions were included with the mount. I suspect that a less technical individual would likely not figure it out.

The part came so fast without extra shipping. It took only 10 minutes to replace water tube and upper spray arm. I only had to remove one screw. Replaced with new parts and reinstalled screw. It was easier and cheaper than calling a repairman.

The pump outlet gasket was sticking out and a screw was missing from the pump outlet housing. This was causing water to flood out under the door.

Once I removed the pump outlet housing I saw that the gasket was out of place almost all the way around. I cleaned around the housing, replaced the gasket and the missing screw.

You need a Torx T-15 for this repair. Note that all of the screws on the housing were loose so you might need to tighten them from time to time.

Be careful not to drip a screw when you are installing it since it's a real hassle to fish it out from under the screen.

Once everything was tightened up, the wash pressure seemed to be much higher.

First I took out the upper rack, unscrewed the old remains and screwed in the new part. Next, I took out the upper rack, turned it over, removed the old hanger (no longer necessary with newly designed part), unscrewed the other part, and screwed on the new part. So easy! And one more thing-I ordered my part on a Fri. and it was on my porch by the following Tues. Now THAT'S service! - Pam

Unplug the dishwasher. Simply removed 8 screws on the inside of the door, removed the interior door panel. Next popped of the plastic protective electrical panel cover. Locate the Thermal fuse that had simple instructions provided. Removed the fuse and replaced the harness. Put everything back together. Plugged dishwasher back into electrical outlet...Dishwasher resumed with the cycle that the dishwasher was in when the fuse blew. Simple, Fast AND Reliable!!!

Well, after I got the the dishwasher apart I realized the problem was not the wash impeller kit, it was the pump/ motor asembly. we deicided to replace the machine. the hardest part was holding the impeller from turning while removing the screw. there is a hex on top of the impeller you must hold in place but, if the machine is old, the hex is brittle,It will break as mine did. you will need to disconnect and take the washer from under the cabinet, and wedge a piece of wood into the motor to hold it. Then loosen the screw and inspect the components. 10 years old, it was more cost effective to replace the dishwasher. i emailed for a request authorization to return. partselect responded promptly with the autorization i needed to return the part. The service was good, and I would use partselect again.

I shut off the power to the dishwasher, then I removed the front panel under the door. On the right side just behind the electrical box there are two wires going up to the hi-limit thermostat, (you may need a small mirror to see it), remove one screw that is holding the thermostat bracket, unplug the wires from the old thermostat and install new one. Screw bracket and thermostat back to the underside of the dishwasher, reinstall the front panel, turn on the power, done.

Need needle nose pliers to remove the keepers in the end stops on basket rails. Basket must be removed to get to the spinner assimbley.
The upper rinse spinner is held in place by a stainless steal bracket. NO SCREWS!
1. You push the spinner assembly up and push it to the back of the machine.
2. Then you pull the spinner assembly down to clear the bracket and then pull it to the front of the machine.
3. To replace it just reverse the procedure.
Used part # 3379329.

There were eight of the star head screws to remove to take the front off the dishwasher, then just followed the instructions that came with the part, which was a thermal fuse and the new wiring that accompanied the fuse in the order. The hardest part was getting the old wire out of the harness with the other three, but once I figured that out just slid the new wire into place and made the connections. I reinserted the screws, turned the power on and knock on wood shes still working.

This gets a little lengthy... but it explains where Cascade Dishwashing Powder came up with its brand name - it's been a cascade project.
I started by replacing the Middle Wash Arm Tube as the old tube developed leaks. As others have stated this is a new design but directly replaceable and easy to do.
This didn't solve the cleaning issue so reading the experiences of others on this site realized I also had broken parts in the Upper Spray Arm Assembly and the Upper Wash assembly. I replaced these and the dishes were suddenly much, much cleaner. These were very easily replaced.
I did find that I did not need the Mount for the upper spray arm (PS402277) as a redesign of the Upper Spray Arm Mounting bracket no longer required it - the bracket simply clipped in -the diagram was out of date.
Everything seemed to go well for about 3 loads when the dishwasher started leaking heavily out of the bottom of the door. I then noticed that the lower Wash Arm Bearing Ring and the Seal, Lower Spray Arm had disintegrated so I replaced those but this didn't affect the leaking. Someone had stated that if the lower wash arm assembly had too much 'wobble' that it cause 'waves' that would leak out the front door... mine had some wobble so I added a nylon washer from Ace Hardware that reduced wobble but still leaked.
I then replaced the Door Seal Kit - this was by far the most difficult part as the door needed to be removed and it was somewhat difficult - and it seemed apparent after we had removed the door that these parts weren't the problem but we replaced them anyway.
Also, someone else had noted that they had to attach the door seal (this is NOT the gasket that goes around the door opening) with a sealant - I had the same problem; the original seal fit tightly with friction but the new replacement required an adhesive - I used silicone. Still leaked.
From here on I can't guaratee any useful information: I took the strainer screen out of the bottom of the dishwasher and found one slightly loose screw holding what I believe is the 'pump outlet' according to the diagram. I had also read that the water fill is controlled not by the float at the bottom of the washer but by the electronics and it was suggested that I disconnect the DW from the power to 'reset' the timer, this I did and hit the 'Cancel' cycle a couple of times to make sure that all programs were cancelled. Whether any of this made a difference I have no idea - except that the dishwasher suddenly stopped leaking and hasn't leaked a drop for at least 20 washes. So I don't know, for sure, why it leaked or how I fixed it, but it's working and washing great now - except the tines on the lower rack are beginning to rust out and breaking off. The rack is pretty expensive but so far I've saved a lot of money and my family thinks I'm a dishwasher genius.

I inspected the pump and checked on-line for instructions . I removed the lower panel and the lower dish rack . Removed the washer head from the top of the pump inside the dishwasher . I next unplugged the wiring after disconnectiong the power supply . Next step was to remove the drain hose from the bottom of the pump . Put a towel under it because it's full of water . Unscrew the nipple from the bottom of the pump to allow clearance so it may be removed thru the top . There are four plastic ears that rotate on the base of the pump . Move them into the outboard position and lift the pump out thru the top. I applied some liquid detergent where the pump seal goes and pushed it back in . Installation is the reverse of removal .

As others have described, this replacement was very easy. The new spray arm is solid plastic instead of rubber (which had deteriorated and was the part that needed replacing). So it should last longer.

You have to keep and reuse the mounting bracket that attaches the spray arm to the upper rack, so don't throw that away!

The replacement was super-easy, and as others have commented, the dishes haven't been this clean for a long time. Well worth it.

I disasembled the inner door and replaced the door switches with new ones.

I removed inner face of door, cut wires leading to door switches, and then installed the new door switches and wire harness.

I removed the rubber boot on the top of the water dispersal unit ( stainless steel wand ) by turning it counterclockwise and the wand came off with ease. I then removed the top unit under it by removing the 8 torx screws and removed it. Under the unit is a cover with 1 torx screw to be removed and removed the cover to access the unit. I was unable to loosen the 1/4" nut on the shaft as it was very tight so I had to remove the unit and lock the motor armature with a piece of wood and removed the bolt. Using the kit I purchased I installed the new parts as required and it works as good as new.

The whole problem started with the upper vent on the door being plugged up with a whole bunch of labels that had been washed off of a bunch of tin cans that were washed prior to recycling them. Te high water float was also gummed up for the same reason and overflowed on the floor, I pulled it up and out and cleaned it up also, it works as good as new.
