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

The repair was surprisingly easy. I only had to slide the dishwasher out half way to reach the screws. It took a couple minutes per side and the job was done. 

Bought new slides (2) for a fraction of the cost the manufacturer wanted. Repaired in 20 minutes or less. 

Followed the online direction... removed the kick plate, turned off the power and disconnected electrical box from DW. Removed two screws attaching DW to counter, lowered DW leveling feet. I did not need to disconnect the drain or water lines as there was sufficient slack. Pulled DW out (partway), loosen and moved air vent out of way. Using a socket wrench removed 4 screws holding the old track to the inside of the DW. Reversed the process and ran DW without the kick plate to verify that there were no leaks. Also replaced the left side rack adjuster as the tabs broke releasing the rack. 

Looked the repair up on Youtube. Purchased the slides and rack adjusters from APP and installed myself (at 73 years old). Instructions and repair went as illustrated but pulling the dishwasher out took more time due to under counter restrictions. Hint (not in video), when repair is complete disconnect dishwasher drain hose from disposal and run a couple of rinse cycles into a bucket to remove bearings that fell into pump without damaging your disposal. Not technically challenging if you can follow instructions but some physical effort required. 

I purchased the parts indicated on this review and... well the dishwasher is working fine now. I cannot complain about the quality of the parts, everything worked extremely well. I do feel like I would have spent less money just buying a new dishwasher. 

We replaced the tracks. 

Replaced pieces with new parts ordered. As others have stated the hardest part was removing the dishwasher from underneath the counter. If you are attempting replacing tracks be sure to turn off water supply and disconnect from unit. Fortunately I did not snap the plastic attachment when I started to slide the dishwasher out-it just started leaking. 

The replacement part was a snap to replace after watching a You tube video. The entire job only took 15 - 20 minutes after I pulled the dishwasher out. Thanks for the great service on getting my order delivered so quickly. Larry C 

The repair took about 30 minutes. The dishwasher had to be lowered and the water and drain disconnected in order to putt it out. The parts were a proper fit. Marked RH and LH side. The parts came second day. 

Slid dishwasher out. Replaced rack slide by unscrewing bolts from outside of dishwasher. AppliancePartsPros was great about sending out part quickly.
