WDT790SLYB0 Whirlpool Dishwasher - Instructions

The repair was similar to the very good video provided by PartSelect. However, I did make a few changes. The new rack was slightly different in the front side compared to the old rusted rack. After I removed the old rack from the dishwasher, I placed the two racks side-by -side to make sure they were compatible. They were identical in the rear structure and overall size, so I proceeded to change out the wheel racks, rack height adjusters and upper wash arm to the new rack. I suggest transferring each part one at a time so you can get the spacing correct. Also, in my case, many of the items needed to be washed with water to remove soap buildup in these parts before moving to the new rack. I would also suggest putting the upper wash arm (needed in this case) on the new rack last. The total job took me about an hour including washing or rinsing all parts and reassembly. This is an easy job, just take your time and do one item at a time so nothing gets mixed up. I used a drill driver to remove a total of 4 Phillip head screws for the rack height adjusters but a regular Phillip head screw driver would work as well.

After I finally got the right parts and installed them I discovered that even though I had bought the OEM part for my dishwasher it not only didn't fit but prevented me from even getting the upper rack back in the dishwasher. The dishwasher won't work with out the upper rack properly in place. Every part store I looked at offered the same part for my dishwasher so obviously Whirlpool made a huge mistake. Since it's not possible to get the old parts back on (one of them was broken anyway which is what started all of this) I had to buy a new dishwasher. I did contact Whirlpool by email but got no response. If you own a Whirlpool dishwasher be very cautious buying any replacement parts.

simply line up the new pin with the rectangular slot in the kick panel and metal panel behind, slide the pin in and turn it with a flat blade screw driver.
NOTE: the original pin was black. A black replacement part cost $29 plus shipping! A knock-off pin was only $6 plus shipping. I got the cheap one and colored it with a black Sharpee marker before installation.

Put the kick plate under the dishwasher and screwed it in. Easy!

Float switch right in front. Did not remove dishwasher. Used small flat screwdriver to un clip cover. Very soft and easy. Unplug and it slides out.
Same with the water inlet. Did not remove and used a screwdriver and small channel locks. Turn off water. Remove hose and remove screw. Slides out. Very easy.

The old filter simply unscrews and the new one screws in.

Top of stop slides on and push bottom in ,will click

I had a common issue on many dishwashers, the final drain cycle was not draining but the pump was trying to turn. Also, the drain pipe was clean. This issue caused a burning smell, like a circuit board heating up. Half plastic smell, half electrical. I bought a replacement pump, followed the pump replacement video instructions from PartsSelect, and it was replaced in under 15 minutes without any tools.

pushed the new retainers in the holes and we are set to go

slipped new one into slots

These wheel assembly that came on the lower rack of my dishwasher were junk! They started falling off within 6 months. I put them back on to the point that the pin in the center of the wheels would no long stay in place, thus the frustrating situation of the wheels falling off often.

Assembly was easy peasy!

My husband did the repair. It was very easy. He basically just popped off the old wheels and popped on the new ones.

removed kick panel with screwdriver, 90 degree turn of screw. Put towel under drain pump. Disconnect drain hose by loosening spring clip with pliers to provide access to pump. released spring clip on old motor while turning counterclockwise to separate pump from drain reservoir. inspect drain reservoir from inside machine to remove any foreign objects. Installed new pump by indexing attachment flanges to notches in reservoir and turning pump clockwise until locking tab makes audible click. reattach drain hose insuring hose is contacting "stop" ribs on drain hose pipe. Run wash cycle on machine to insure there are no leaks. Re-attached kick panel.

pulled the dishwasher out (took the most time-1 hour) and 30 min. to install new door balance kit and springs. Replace both sides while the unit was out.

Pulled washer out far enough to put 2x4’s under front feet. Removed front panel, I clipped wire connector and unplugged it. Pushed plastic locking lever in and twisted unit counterclockwise. Wiped inner rim and reversed above procedure to assemble.
