KUDC10IXBL9 KitchenAid Dishwasher - Instructions

1.Check the lines for any obstruction. Gunk can easily build up. I have used the dishwasher for approx. 10 years. I do rinse/scrap dishes prior to loading.
2. Drain all remaining water.
3. Unplug the dishwasher.
4. Grab a towel and proper screw driver. Unscrew the bottom protective plate. Remove the insulation plate.
5. The drain pump is located to the bottom left. Have your towel under it. Unplug it gently. Turn counter clockwise to remove.
6. Install the new drain pump (reverse order)
7. Return the insulation plate. Screw back the bottom protective plate.
8. Plug in

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.

Very easy to repair with the replacement wheel assembly. Popped out the broken one, popped in the new one. Price was nothing compared to having an professional repair person come to the home. Glad I found you on line!

1) Remove the racks

2) Unattach the feed tube the runs from the bottom of the dishwasher tub along the back to the top (this is the grey plastic tube that the top rack sprayer plugs into). This is done by unclipping the tube in two places, one stainless clip is in the back of the tub and one stainless clip is on the top of the tub.

3) After the tube is loosened from the clips, give the tube a 45° twist clockwise (relative to the bottom of the tub) and then pull up. This should remove the entire feed tube and bottom sprayer assembly.

4) There are now 4 stainless steel torx screws visible on the bottom of the tube. Remove the screws using a torx driver. Remove the grey plastic "gear looking" piece that was held in by the screws by pulling straight up.

5) On the left hand side of the tub you will see one more (smaller) torx screw. Remove this screw and then with a pair of plyers, give the housing piece that was held on with the screw a tug straight upwards. There is a post sticking straight up that will help you do this.

6) The grinder assembly is now visible, and in my case, completely jammed with paper. Pull the grinder and screen out of the groove it is sitting in.

7) Place the new grinding and screen into the groove. The grinder blade will have to be pull back (toward you) so the grinder coupling teeth can properly engage with the motor coupling teeth. This may take some fiddling.

8) once the grinder is installed, reverse all the steps starting at step 5.

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!

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.

.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.

I looked up the most common problem with this model and it was the chopper assembly. I removed everything down to this. Sure enough, mine was broken off and the screen was completely clogged with debris. It was not difficult to replace, but it did take me a few minutes to slide it in to place. Ladies, you can do this. No need to call a repairman! Look up the repair manual and see where the assembly is. I had no idea it was even there. My dishes are spotless now.

Discovered through internet that it may be a bad chek-valve, Opened washer up and removed inside covers. Actually found that the chopper assembly was bent and non-functional. Ordered new assembly plus ordered a new check valve since the other was 8 years old. replaced both at the same time. Dushwasher works like new once again.

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.

it was really easy i removed the lower spray arm then
i removed the four hex head screws that hold on the
fine mesh screen then i pulled out the plastic insert
which exposed the cover to the chopper assembly
removed a smallhex head screw pulled off thecover
and there was the chopper and checkvalve replaced
both with a new one and the dishwasher works like
new thanks a lot im sure a service call would have cost over a hundred dollars

removed old gasket, installed new.
No Leaks!!
Saved the cost of a new dishwashers

I followed the YouTube video exactly and it went very well

Rolled out old, rolled in new.

If your not getting clean dishes this is an easy check to make that will likely turn out to be your problem. If not, you need to get this far anyway and it's an easy check to make. Remove the top and bottom rack. The bottom and top sprayer are connected together as an assembly by the water transfer pipe the goes up the back side of the dishwasher interior. This needs to be removed. There are two clips that hold the assembly in place at the middle rear of the washer and the top of the washer. Grasp the water assembly with your hand at the location of the clips, top one first and give a twist that rotates the piece out of the clip. Once the assembly is free from both clips hold the assembly at the lower rear where it starts up the back of the washer and move the whole thing to your right to turn the base clockwise. The whole thing will release from the bottom of the washer and come out as one big piece. Set it aside and you will see four torx head screws that were hidden under it. Remove these screws and the round screen assembly that they are holding to the bottom of the washer. Set that part aside as well. Now your looking at the well area where water collects to get into the pump. There will be a little standing water there, it's normal and not a problem. To the left side of the well an inch or two under water you will see one Torx head screw. It's one bit size smaller than the other screws. Remove it and pull up on the cover that it is holding in place. Now you are looking at the chopper assembly, it's a four bladed knife that rotates across the face of a screen. If you can rotate the knife blades and not have the shaft behind the screen move, it bad! Grasp it by the top of the screen and lift it slightly and pull it toward you to remove it. The shaft that turns the blades has worn away where it connects to the blades. It doesn't turn anymore so the screen is plugging and no water is able to get to your dishes. Order a new one and put it back in the same order you took it apart. It helps to have a little screw driver to lift the knife blade away from the screen when your putting in your new part. Load up the washer and give it a test run. YOU DID IT!!!
