Part #WP99002780

If you find that your dishwasher is making loud noises or the lower rack is getting stuck when you are moving it in or out, it could be that the lower wheel assembly needs to be replaced. The dishrack wheels allow for easy movement of the dishrack in and out of the dishwasher. These rollers tend to wear down at the same speed, so it is recommended to replace both pairs at the same time. Open your dishwasher and remove the bottom rack, locate the locking tab, and rotate until it easily slides out of place. Slide the new wheel over the shaft and locate the locking tab to snap back into place.

Water dripping from right corner of door
599 of 613 people found this instruction helpful.
  • Tim from Ringgold, GA
  • Easy
  • 30 - 60 mins
  • Nutdriver
Took out about 7 torx screws to remove the inner door liner. Discovered evidence of leak coming from the sop dispenser latch, and noticed the grommet had turned soft and was torn. The grommet is only about 1" square. Used nut driver to remove two screws to remove latch assembly. Slipped old grommet off and put new one on, and reattached t he latch. The foam seal at the bottom of the door looked worn, so we replaced it with weatherstripping from home improvement store. The main door seal was brittle, so we replaced it too - just grab an end and pull the old one out. The new one was installed by starting at one end and we just pushed it in place. We used a nut-driver to push it in - we were afraid a screwdriver might damage it. The new door seal required us to latch the door to get it to stay closed the fist couple of days, but now it has loosened up a bit and works as expected. And NO MORE LEAKS. Cost is much less than a new unit!

I opened the end stop of the rack, replaced the roller, and put the end stop back on. I can't believe I paid the repairman the last time $125????? An he put in a regular screw that rusted and broke the roller. Took me 3 minutes! Thanks

The dish rack had two sets of adjustable tines that had never worked.

  • Difficult

I ordered two clips just in case. Turns out I needed both of them. Since I hadn't seen the adjustable tines installed, it took some time to figure out how to put the assembly together.

For some reason I had the dishwasher for 7 years before it occurred to me to order the replacement parts. It's much more efficient to use wit h the adjustable tines properly installed as I can load approximately 25% more plates than before.
