DU1145XTPBA Whirlpool Dishwasher - Instructions

Cut power and turn off water. Pulled the dishwasher out of the cabinet. Removed internal spray unit. Lay a plastic bag on bottom of tub in case a screw falls from upper spray assembly while removing. Disconnected and drained all hoses. Put down plastic lined tarp on floor. Lay dishwaser on its side onto tarp. Removed hose from recirculation pump, removed water sensor and recirculation pump from housing and detach electric connection. Removed 3 plastic push clips and removed entire motor-pump unit from tub. Position new motor-pump unit into tub. Replace 2 push clips into position, then used a flat screwdriver to put some tension and position plastic pump assembly so I could insert 3rd push clip into position. Replaced all components & reconnect hoses. Turn on water & power. A relatively simple repair. Too bad the original motor-pump only lasted 3 years. Not built like the used to. Thank goodness for Part Select.com Great schematics and descriptions. Excellent website, service, delivery and excellent Part! Thank You!

.The easiest way to complete the impeller and chopper motor replacement is to disconnect the power, water and drain line, remove the dishwasher from the cabinet, set the washer on its back.

From this point everything is visible, pump housing, motor, etc. and it's a matter of disassembly and reassembly. Make note or a drawing of where all the wires are connected so you reconnect them in the right spots.

Reinstall water lines and power and check for leaks before replacing shield or kick plate.

Disconnect the water supply, the drain line, and the two screws that go up into the cabinet frame, then pull the dishwasher out from under the counter. Tip the unit onto it's face and the main pump/motor is facing up. Turn off the power then unplug the electrical connector from the motor. Remove the single bolt at the base of the motor then turn the whole motor ~1/4 turn counter-clockwise. A firm pull will remove the motor/pump at this point.
The new motor/pump has a new seal. See that the arrows on the pump volute and the motor frame are lined up before inserting into the housing. The new motor/pump slides into the housing easily and a 1/4 turn clockwise will pull it in tight. Re-install the locking bolt and revers the rest of the steps to get running again.

Very easy repair !!! I ordered my heating element on a Friday , it was on my porch Saturday. I used the directions that Parts.com sent me . I also read everyones Installation instructions ..... Every step was very easy . I did watch a utube video , so I couldn't screw this repair up......... My wife had a new dishwasher picked out for $ 579.00 , my part was $29 dollars , savings $550 dollar ...... After the repair , I ran the dishwasher and the blinking clean lite took care of itself ... The water has never been this hot and dryers the dishes like it was a new dishwasher ...... My advice , read everyone's Installation instuctions and watch the utube video .....

Other than the repair part being at the bottom of the dishwasher and you had to lie on your stomach to do the swap out, it was just one screw, move the part out a little closer to you then pull off one electrical wire, and pull off one small hose and using wrench unhook the other small hose.

Of course I had to take it apart a second time because of a leak, but using 3 or 4 circles of the white plumbers tape, it took care of the leak.

If your chopper assembly has a catastrophic failure like mine did, chances are it took out the teeth on the circulation motor as well. This will lead to the teeth on the chopper being destroyed by the impeller as soon as you turn the dishwasher back on. First, follow the instructional video to remove the motor (found on this site on the circulation motor page) and chopper assembly (also found on this site on the chopper assembly page). The impeller is screwed onto the input shaft of the motor, and you must keep it from turning so that you can unscrew the impeller assembly. I removed the back cover of the motor (there are four screws holding it on) and held a flat pry bar on the rotating assembly inside the motor to keep it from turning, then unscrewed the impeller from the shaft. Mine came off very easy, but be careful not to let your pry bar slip or damage the motors internals. After that, install the washer and grommet from the impeller seal kit on to the impeller, and screw it back on while keeping the motor from turning with your pry bar. Lastly, reinstall the motor and chopper assembly per the aforementioned instructional videos. The whole thing took around an hour to do, and it is much cheaper than replacing the entire circulation motor.

The repair was really easy. First disconnected electricity staring with fuses and removing wires from dishwasher, then disconnected drain hose and water hose. Pulled it out and removed pump turning clockwise no need for tools and same way installed new one. Very easy

I followed the YouTube video exactly and it went very well

I followed the PartSelect video to replace the feed tube assembly with spinner and the spray arm seal for the middle wash arm. Washing performance was better, but a couple weeks later the dishes on the bottom rack suddenly stopped getting clean. I decided I probably needed a new chopper assembly, which is identified by PartSelect as the cause of problem for 48% of the cases of dishes not getting clean. Before ordering the chopper assembly, however, I followed the video about how to replace the chopper assembly to determine whether the chopper assembly seemed to be worn out (the video shown at https://www.partselect.com/PS11722146-Whirlpool-W10083957V-Chopper-Assembly.htm). It was worse than I anticipated. I found the holes of the chopper assembly screen blocked by food, and the spinner in front of the screen had broken apart. In addition to finding the pieces of the broken chopper assembly, I discovered a treasure chest of debris, including about 8 pieces of broken glassware, 3 twister ties, a half-inch button, a 3/4-inch screw, and dozens of small pieces of metal. I poured water into the area and used a kitchen baster to suck out the water with all the pieces of debris, finishing the clean-up with paper towels. I ordered a new chopper assembly to replace the broken one, and the part arrived in under 48 hours. I relied on the same video to install the new chopper assembly. The only tricky challenge was getting the new chopper assembly back into place. I first tried needle nose pliers in two sizes, as recommended in the video, but what worked much better for me was using two chop sticks that were each about 1/4 inch square from top to bottom. Needle nose pliers are slanted, but the chopsticks did not vary in thickness and separated the screen from the spinner an even distance apart, making it easier to get the gear shaft on the chopper assembly to align in a straight line with the gear shaft on the pump motor. I also rotated the two gear shafts so the gears of the chopper assembly would mesh correctly with the gears of the pump motor shaft. The video cannot show that step very well because the man's hand blocks vision of how exactly to fit the chopper assembly into place. The video also fails to warn about possible debris around the chopper assembly and to explain how to clean out the debris. After finishing installing the chopper assembly my 14-year-old dishwasher cleaned my dishes as well as a new dishwasher. I spent a total of $110.24 on parts and shipping and invested a couple of hours total. The alternative would have been to spend $800 on a new dishwasher or wash dishes by hand. I am very, very happy with the outcome.

I removed the old gasket simply by pulling on it. I compared its length to the length of the new gasket, figuring there would be some trimming to do -- there wasn't. The replacement was exactly the same.
I placed a mark on the center of the new gasket, and marked the center of the mounting groove. I aligned the two marks, and pushed the new gasket into the groove, starting at the center, and worked my way out towards the two ends. After getting a majority of the new gasket to seat by hand, I GENTLY used the tip of a slotted screwdriver to ensure that the New Gasket was completely snapped into place.
The fit was perfect, and no more leaks. This repair was so simple, I'm embarressed for putting it off for so long. ;)

I followed the video directions on line...they were exactly to the point to do the repair.

i asked the vrtual repair stating the problem of my dishwasher machine ,he then give me two possible solution change the water presure switch which i did order the part and installed it and it works now..............thanks partselect.

Everything worked perfectly---thanks to the suggestion of your call center agent. She suggested that since the replacement door handles were no longer available, I should consider repainting them--it worked like a charm. Please tell her she was a life saver. We rent that house in Fl and my returning tenants had complained about the discoloring refer handles. Thank you

I pulled the unit away from the cabinet, unplugged the washer and water line(not long enough to reach) removed two nuts from the underside and replaced the heating unit.

pull out the dishwasher
lay it on its side
use a 1/4" drive socket with extension and a universal joint to undo the the hidden bolt,
twist the motor 1/4 turn. this is the hard part you have to pull fairly hard and rock the motor around a little to get the o-ring to let the motor slide out.
lube up the new motor with jet dry or soap and insert back it, turn it back 1/4 turn, install the bolt and plug the motor control wires back in, then reinstall it back under the counter
