How to Troubleshoot & Replace Whirlpool AP6783992 / W11259785 Track, Assembly (Lh)

Ordered parts from these fine people. The parts arrived 1 day later. I pulled the dishwasher out, replaced the top rack track on both sides and was back in business. It took me three times as long to get the dishwasher out as it did to replace the top rack tracks. Very simple repair once the dishwasher was out of the recess. Track attached by 4 screws (two on each side - I replaced both tracks) located on the outside of the dishwasher cabinet. I used a phillips screwdriver to remove and replace the tracks. All totaled, time to replace the tracks was 10 minutes. Obvious that the manufacturer recognized the defect in this part. The replacement has the ball bearings contained in a different material than the original part. Very satisfied with AppliancePartsPros and will use them again. 

Ordered the left and right top rails and they arrived fast. Repair was about 20 minutes only because you have to pull the dishwasher out to access the mounting bolts. Works like new!! 

New tracks were very easy to install. I had to pull out the washer but did not disconnect any hoses and the install was simple. 

We pulled the dishwasher out part way (did not have to pull it all the way out as some have had to do). The fasteners for the upper track are on the side of our Maytag washer. We simply had to take off the screws holding the part and replace the track. One of the trickier things was removing the rack from the track, plastic parts were brittle (dishwasher only 4 years old) and broke on each side. Fortunately it did not prevent the rack from being able to be used effectively. 

I replaced the two top brackets so the top tray would slide in and out as designed. 

Ordered replacement drawer slides and replaced them. 

I had a lower rack track assembly break a year or so ago, so I knew the problem. When I did that I ordered the track for the other side, but never replaced it. This time I replaced both that track and the two on the top rack. Easy procedure, just unplug the dishwasher, remove the rack(s), unfasten it from the cabinets, slide it out, that exposes the hex-head screws that hold each of these in place, remove those and the track, put the new track in, secure the screws, plug it back in and the job is done. Takes about 15 minutes to do three. Note that the left side track screws are covered by an air duct that is easy to loosen and move. A clip on the top of the duct holds it down and it locks itself in place to the air source. Just slide that clip up, gently pull the duct upwards, slide it out from the bottom and move it out of the way. The most delicate part of this repair is removing the racks. The locks that secure it in place can break off, especially if they have been in use for a number of years and made more brittle with the heating and cooling inside. I anticipated that and ordered those parts, as well. The top rack uses two WPW10546503 on both sides. That is also an easy fix. 

Purchase the slide from y'all 

Followed the appliancepartspros videos which accurately described exactly how to repair the problem. Would definitely recommend using appliancepartspros to everyone needing to repair an appliance. 

I replaced both slides with new ones.
