Product review (5 stars): Amazon comes to the rescue!
We have 2 Kitchenaid dishwashers in our primary kitchen and I alternate use of them so wear and tear should be the same on both dishwashers but this is not the case.
The door balance piece on the dishwasher next to our primary sink broke on the left side, we looked at the manual  for the dishwasher and realized we could order the replacement part through Amazon, ordered the part and my husband replaced it. WOW!  The door is back in perfect working order!  Thank you once again, Amazon!
