DU640XTKQ0 Whirlpool Dishwasher - Instructions

Turned off water supply. Then removed water supply line, secondary hose, and screw securing inlet valve. Valve will slide out. Removed brass elbow fitting from old valve. Applied plumbers putty to threads on both ends of elbow and attached to new valve. Installed new valve and secured with screw. Re-attached hose and supply line. Turned water supply back on and checked for leaks.

Disconnected the damaged hose extension from the dishwasher outlet drain hose and the connection to the sink drain. Removed two clamps. One a spring clamp and the other a screw clamps. Connected the new extension hose with a spring clamp to the dishwasher outlet drain hose. Connected the other end to the sink drain with a screw clamp. Checked for leaks. Good to go!

This is the second time I have replaced a rack. You just pop on the new rollers and you're good to go!

Drained washer with hand pump. Thermo fuse had blown. Removed control panel and substituted a 15 amp automotive ATC fuse, shimming the blades with aluminum foil. Removed dishwasher from counter niche. Tipped dishwasher, removed and inspected drain pump and recirculating pump. No apparent problems noted. Temporarily rerouted supply and drain lines and restarted. Grinding noise clearly came from the drain pump. Ordered new drain pump and replaced.replaced 20 amp thermo fuse.

From searching the partselect site, I was able to determine that the fuse was most likely the faulty part, and probing the voltage confirmed it. So I ordered the Fuse Kit.
I was very pleased with the level of diagnostic information available on partselect.com.

The kit instructions were clear. With power off, I removed the old fuse, clipped the existing wires, stripped them, and reattached to the new wire connector. Then I snapped the new fuse in place and put the cover panel back on. Everything works fine again and my wife was very pleased.

First, I turned the power off at the circuit breaker.
Next, removed six screws securing front panel to the dishwasher. Then, disconnected power supply to the dispenser. Followed by unscrewing the four screws that held dispenser in place. Easily removed unit and replaced with new dispenser. Secured in place with screws, then connected power supply. Then, fastened front panel and turned circuit breaker back on.
Viola! New dispenser is working like a charm!

No brainer.. the correct part was shipped and the Mrs is now happy

Repair was a "no brainer". Pulled out the old gasket, started the replacement of the new gasket in the lower right hand corner and worked all the way around the opening, then trimmed excess gasket of about 2" with a pair of scissors and I was done. Total time - less than 5 minutes.

I opened the dishwasher door, removed the old tired seal in a manner of seconds. I measured the old seal against the new, same length, so no cutting. I started on one side pushing the seal in to the groove, made sure the seal was centered in the door. (not too long on one side or the other) It took less than 5 minutes to place the seal and check that it was all the way in, all around the door. I wiped the door down with some cleaner, where it contacts the seal. The door was harder to close, but I expected that until it breaks in. I ran a short load in the dishwasher with no leaks. :)

I had to remove the baskets, spray assemblies (no tools needed) and disassemble the section of the pump that contained the chopper assembly. (removing three Torx screws)
I had to remove a part of the old chopper that had gone into the pump, but I was lucky that a magnet grabbed it so I didn't have to disassemble the pump.
The total repair was not difficult. The only problem was access (hands in the way while repairing difficult to see) and compressing the spring on the new chopper while trying to slip it into the groove.
The parts came in three days and they fit perfectly

After looking at what everyone else had done, I decide that I would take the dishwasher out of the wall space and set it on its side. This require me to turn off the power first. Then I pull the diswasher out from its space in the wall. I turned off the the water and then took off the water hose, then took of the return hose. There was water left in both, so there was a little water on the floor as a result of this. Then I finally pulled out the unit and laid it down on its side. The motor was very visible and was easy to access. The hardest part was finding the bolt to take it off. I pulled off the power connector to the motor and then took off the one bolt that was holding the motor on the washer. Then I twisted the motor, but it would not come off. I finally got a screw driver and put it in the small opening between the motor and the connection and it finally came off. This took all of about 30 minutes. Once I got the motor off, I notice that the aluminum grating inside was dirty and needed cleaning. So I cleaned this and put it back inside. The new motor came with every thing, so I put it in and twisted it. Then put back in the bolt, reconnected the power cable, put back on the water and reconnected the output cable. In order to make sure there were no leaks before I put it back in for good, I ran a short wash to check to see if everything was tight. There were no leaks, so I put everything back in the wall. It really did sound very nice now. This dishwasher unit came with noise padding, so I put that back as well. The dishwasher, now is very quite and I don't mind it running any time during the day. The hardest part about this is getting the motor off and find the bolt. It is down between motor and the unit and there was some aluminum between this and the dishwasher, so you need a long nutdriver to get it off.

We took the rollers off the old one (new ones came with the dishrack also) and put them on the dishrack (they snapped on). There was also an extra piece that we figured out how to put on. Then slid it in place and it was fine.

Turned off the power at the breaker, turned off the water supply, disconnected the water line, removed all three racks, pulled dishwasher out from under the counter, laid the unit on its back, removed the flat plastic water lines from inside the dishwasher, disconnected the hose and all wires (plugs) that were attached to the motor & pump assembly, removed three plastic wedges that held the pump assembly to the bottom of the dishwasher, tried to remove the motor & pump assembly from the inside of the dishwasher but it wouldn't fit through the hole, removed two parts from the motor a silver cylinder with two wires attached to it and a white plastic piece with copper wound wires and magnets in it so that it would fit, once the entire assembly was out removed one screw that holds the motor to the plastic pump assembly, twisted the motor counter clockwise the pulled it straight off, after installing the new motor I removed the silver cylinder (maybe a capacitor) that was attached to the motor leaving the two wires attached to it so that the assembly would fit through the hole in the bottom of the dishwasher, cleaned the rim of the hole and the rubber gasket on the assembly, put the assembly through the hole in the bottom of the dishwasher, installed the three wedges to hold it in place, then put it all back together. When I ran the dishwasher it was as quiet as when it was new.

The repair was easy in that there were no surprises due to the video. The extra time was due to not being able to pull the appliance out for easy access. It was great to have the percentage for solving the problem identified on the website.

Repair man said I needed a new pump and would cost $350 to repair. This dishwasher was only 5 years old and we only use about once a week so didn't think the pump was gone. Went on this website and read some stories. this model has a mini garbage disposal with a chopper and screen which gets clogged up and prevents water from circulating. You can clean the screen without removing the dishwasher. Remove the cover plates on the bottom with 4 screws and the smaller cover plate underneath. Remove screen, clean and replace. If the chopper is broken you can order a replacement for $21. There is another story on this site with a lot more detail so I wont repeat here.
