Product review (1 stars): works for some models but not for others
My KitchenAid dishwasher, model KUDP02IRBL3, suddenly began making a terrible noise when opening or closing the door. I 'researched' the problem and found that the original door balance parts had been replaced with the Whirlpool 8194001 kit. I found mixed reviews online that stated how great and how lousy it was and decided it must have something to do with the exact model of the unit. So I purchased the kit online and when it was delivered today I went right to work to replace the pulleys and ropes as supplied. Unfortunately, for my model, the new items when installed created noise twice as bad as my original problem. The pulley design is quite different and the supplied ropes are at least 1 1/2 inches shorter - I tried the new pulleys with my original ropes and a similar noise remained. Finding no source for the original parts I then  installed, removed, changed sides, etc. with each of the original parts one at a time. This resulted in finding that I still had two good ropes, one good pulley and one bad pulley. Experimenting with the bad pulley, I pulled the wheel off - it just pulls off and snaps on without too much pressure - cleaned the spindle and the inside of the wheel as good as I could, then I put the wheel back on by reversing it on the spindle (i.e. pulled it off, flipped it over and snapped it back in place). I then reinstalled all the original parts and now the door opens and closes without a sound. Last, I threw away the junk called the Whirlpool 8194001 and wrote off the cost as a lesson learned on the Whirlpool replacement kit.. Bottom line is that it seems from reviews that this kit may or may not work on your specific unit! Too bad someone from KitchenAid, Whirlpool, Maytag can't put together a real list of units the kit actually works withas it is obviously not a one kit fits all.
Hope this helps someone in the future.
