DP1040XTXB1 Whirlpool Dishwasher - Instructions

I followed the YouTube video exactly and it went very well

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. ;)

Had to use a standard flat screw driver to pry off the old mount. used a phillpips head driver to fasten the mount to the spray arm and pushed the new mount in place.

When the top rack stopped cleaning, I tracked down the problem to the food shredder/chopping blade, and then to the impeller that drives the blade. The knob on the impeller had sheared/broken off. That meant removing the motor, and replacing the impeller. Four hours, a band-aid, and a trip to Home Depot later, here are my suggestions

1. Look for videos – this site is awesome, but they don’t have a video on this particular repair. I found 4 that got me close to knowing what I was doing.
2. Do all the “remove internal stuff” - you had to anyway to find the issue with the shredder/cutting blade
3. Take pictures as you move along, you’ll need them when you have to remember the placement of the water line, drainage hose, wired connections etc.
4. You need a 1/4 inch socket set. A 3/8 drive will NOT work (it won’t fit between the shroud and the base). Don’t start working on the repair, unless you have a 1/4 in socket with about a 6" extension
5. Someone at Kitchenaid should be shot for having the waterline connection facing the back of the unit. Use a short adjustable wrench
6. The order comes with a washer, but when you take the impeller off this model, you’ll see you don’t need it.
7. Placement is everything – there was zero clearance between the bottom of the unit and the floor. Placement of the water line, drain hose, and power line was critical – had to re-position the unit about 7 times to get it to “play nice”.
8. Hindsight – only needed to remove the wire harness for the motor (take pictures)
9. Hindsight – gloves are a great idea – sheet metal is unforgiving

I took out the old one and started in the lower left corner and threaded it all around the edge to make sure the placement and length was correct. Then I came back around with a plastic spatula to firmly seat the gasket into the groove. Worked perfectly and havent had any trouble since!

Just followed the YouTube video they sent with the receipt.

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.

First research then troubleshoot
Removed
1 Upper rack
2 Lower rack
3 Lower Wash Arm and Strainer Parts
4 Upper Wash and Rinse Parts
5 Accumulator assy.
6 Motor shield
7 Inlet protector (most difficult)
Noticed blade was broken off chopper assy.
Replaced chopper assy.
Runs and cleans like new.
Most difficult step was to remove Inlet protector
After removing two torx screws (#15) used small pry bar to lift inlet protector from position. Not easy to accomplish with hands alone. Inlet protector fits tightly into position.

The repair was easy. Getting the unit to slide out from under the counter was more time consuming.
After water and power is disconnected, tip the unit over onto one side to gain access to bottom. Look for two white composite plastic posts (insulators) about 2" long each with a single wire inside. Remove the two wire connectors then unscrew the insulators from the old heating element using an adjustable wrench. Inside the box remove the two metal element supports and pull out the old element. Clean and dry the area in and around the openings where the new element will be re-inserted. Carefully place the new element into the holes with the included new rubber washers. Re-install the two metal element supports on the inside of box. On the bottom, re-install the two insulators to the ends of the element, do not to tighten too much to avoid over compressing the rubber washers which could cause premature cracking. Reconnect both wires and check continuity from the door mircro-switch (white-violet) lead to the (white-red) lead on Electronic Controller connector #1 (P6). The circuit thru the element should be good if the Multimeter reads 10-35 ohms. Put the unit securely back under the counter and run a test wash. Works fine now.
I do recommend, if don't know how to use a multimeter or are concerned about accessing the electronic control box; contact a professional.

I turned off the power to the dishwasher, removed the kick plate, raised the front levelers, disconnected the electric to the appliance, turned off the water supply to the appliance, disconnected the water supply, disconnected the drain system from the garbage disposal, unscrew the appliance from the countertop, then I remove the appliance from underneath the counter. I then tilted the appliance back and then in screwed the plastic retainers that held the heater element in place, removed the old one, replaced it with the new one in reversed the whole process

Looked at other side of top rack which still had the stop. Just had to orient the direction of the stop and push it firmly onto the rack arm. Took a couple tries, but it went in and locked. Works perfectly. Inexpensive and easy fix to to very annoying problem.

So I decided to stick in some CLR to see if it would clean it up. Well it got considerably worse. So ordered the new faucet adapter, threaded adapter and the two washers, due to not knowing what i would need. It came like unbelievably fast considering it was Christmas time. Unscrewed the old one from the faucet, screwed on the new one. hooked up the dishwasher, watched it for a bit for any leaks at the connection, and it worked great! I seem to have more water pressure too coming from the sink faucet. Thank you so much for the quickness in sending out my order! -- Scott

no actual 'repair' was necessary, but, i was blown away at the speedy process of ordering and delivery of the part.

Simply made sure the cap was securely in place.

Eay repair. Replacement tube was one piece and only required removing one phillip's head screw to replace
