I began the repair process with basic troubleshooting. The two-year-old Whirlpool dishwasher was not washing. At first, I thought it was not getting water. I did a system drain which removed most of the water. I waited a few minutes then attempted a light wash cycle without success, but I did hear the unit getting water. And I noticed the detergent cube slightly moistened on the floor of the washer. Google led me to your YouTube videos. I assumed (and hoped) it was the pump. From what I read the assembly was the easiest way for a non-professional to repair the appliance. I ordered the assembly the Saturday before Christmas; we had been without a dishwasher for eight days and handwashing was getting very old indeed. Checkout on your website allows different shipping options from basic to the next day. I chose the “Standard” as it looked like it would get here within a week. It was here the next Tuesday, Christmas Eve! Guess what I did Christmas Day?
I decided it was easier for me to remove the dishwasher from under the counter so I could access the bottom directly as my flexibility is limited. It also allowed me to leave the water and electric connections intact; I did turn both water and power off. Before starting on the assembly, I removed the interior racks, strainers, and water channels putting all the small parts in a zip-lock bag. I laid the front of the unit down on towels to prevent scratching the stainless steel and to allow access to the bottom. I removed all electrical connections to the pumps, the turbidity sensor, drain line, and drain pump as recommended by your YouTube video. After all, was done, I unlocked the retention tabs and attempted to remove the assembly.
The old assembly needed some physical persuasion, as in a serious love tap, to dislodge from the bottom of the machine. Once loose I righted the dishwasher and removed the assembly from the interior. I removed the new assembly from the packaging and placed it on the interior bottom. It did not snap in place as your video showed. This was the most difficult task for me. I ended up locking one retainer tab and using a home-built lever to pry the assembly into place than returning the washer face down and locking the other two retaining tabs. Once in place, I reinstalled all electrical connections dressing all wires in the appropriate clips. Whirlpool engineers did make this part easy as each plug has small teeth arranged so it is unique to each motor.
I installed all interior parts, re-installed the dishwasher under the counter, then restored water and power. I ran a light wash and checked for leaks; once I confirmed the repair was a success, I installed the bottom kick-plate.
The repair was not extremely difficult for someone handy; maybe a 5 on a 1-10 scale. I have some health issues that prevented me from continuous repair tasks, so it took me a couple of hours. But if I look at the total time spent; it was probably less than 45 minutes. As with all jobs, take notes, use your smartphone camera to record what things look like before you start, and use common sense. Safety should always be your first concern; make sure you minimize shock hazards and avoid rushing. Benjamin Franklin is quoted as saying “haste makes waste”, a good bit of advice in today's’ “gotta have it now” world.
