DU4040XP1 Whirlpool Dishwasher - Instructions

Watched "Steve" install the drain and wash impeller kit and then I did it.

My husband took the dishwasher apart three times, it was a little frustrating, but was worth the $50 part because it made his wife, very, very happy! A dishwasher operating is on the top 5 list of favorite electronic items in our house.

Replaced the lower seal, drain impeller,chopper blade, and wash impeller. Problem is still not solved but the inner parts have been replaced. Only thing logical next is the check valve. Unit cycles well and if I turn the dial to just before the rinse cycle and watch, I do see water draining from the unit...Of course while replacing these parts, I checked other things and found a loose spring behind the front cover. It can be seen on the diagram as it is part of the detergent door mechanism (or so I believe), but it is not clear on where the spring actually connects to.

Watched your video

I could not find a 90 degrees 1 inch car wrench and by them the impeller head wish is plastic was all run down so nothing will hold it, finally, I heat up a flat screw driver and cut the impeller near the head whit the help of a hammer , and them I could grab it with a pressure wrench and loose the screw up. finally the fix when fine and is working good. the parts are just the ones I need it. Thank you.

We followed the excellent video until we couldn't remove the outlet impeller because the motor shaft was not being held by the failed impeller. We drilled small holes around the impeller shaft until we could break off the upper part of the pump shell. Then we could hold the motor shaft with a vice-grip pliers by squeezing the shaft of the remaing impeller piece. We then removed the retaining screw and the rest of the impeller. Then evrything went well by following the video. There was still a bit of doubt because we discarded more old parts then expected but the machine now works well and we see no leaks.

screw it in then hook up the hose.

1. Turn off the electrical switch that powers the dishwasher. 2. Open the door of the dishwasher and find the two phillips head screws that secure the top of the dishwasher to the kitchen counter. 3. Remove the screws. 4. Gently move the machine side-by-side a bit while pulling it out onto the kitchen tile (be careful, the water-supply hose, electric cord, and dishwasher drain hose may not be long enough to allow you to pull it out very far - don't break or kink the hoses). 5. Remove (pull off) the black plastic fastener located on the bottom/rear of each side of the dishwasher. 6. Remove the old surround. 7. Lay the new wrap in place and secure with the two plastic fasteners. 8. Push back into place, secure the two screws, check your hoses.

Unsnapped the old rollers and snapped in the new ones. Worked great and easy. I was very pleased that the parts came so soon as well. Thank You, Ms. Cason

Turned off water and power. Used small nut diver to remove two upper screws from kick-plate, and loosen two screws in lower key slot of kick- plate. Removed kick- plate. Used plier to compress snap ring and remove hose to washer. Pulled off electrical connector. Used 5/6 wrench to remove copper water inlet. Used nut driver to remove two screws holding old valve. Once out removed the water connecting elbow from the old valve and installed it on the new valve. Reversed process to reinstall. Didn't even have to remove washer from the counter. My 25 year old washer is working like new again.

Performed repair as to Video shown in receipt after purchase of spring plus we used a friend who has same dishwasher and has performed the same repair recently, video was easier to follow though. All you do is push off lid with a screwdriver and pop off as per instructions on video then unlatch spring from ledge and pull off post, then just reinsert new spring in reverse order or follow video instructions either way is easy and takes about 15-20 minutes to install

This Whirlpool model has the water inlet valve located in the front left of the dishwasher. It was not necessary to remove the dishwasher from under the cabinet. Disconnect the power at the breaker box and turn off the water supply to the dishwasher. Place a towel under the Valve as there will be a small amount of drainage from the water lines and the Valve when disconnected. After removing the front plate on the bottom, I could easily access the 2 screws securing the Water Inlet Valve. Disconnect the water lines on the Inlet Valve and the power connection. . Mount the new Water Inlet Valve, re-connect the water lines and the power connection to the Valve. Turn on water supply and check for leaks. Turn on power.

Used the diagram and disassembled and reassembled.Used most parts that were in kit as it also fit other models and did not need all the parts.

Dishwasher Stopped then only made a humming noise. Started with the Video on your site and it was quite helpful. I had trouble holding the drain impeller with the wrench. Used a drill to bore holes around the center and then broke the outer ring off to get a good hold on the center. Then was able to remove the bolt. The rest of the repair was easy. Something had caught the chopper blade and unraveled the spring. Replaced all the parts and it is working fine now.
