Product review (5 stars): Don't hate my Bosch dishwasher now!
One of the things we were excited about when we bought our house a year ago was that it had a high end cook's kitchen, including a Bosch dishwasher.  However, every time I went to pull it out after running it, the whole lower carriage would jump off track and all the dishes would move out of place and I would have to pick up the carriage several times, with all the dishes still in it, trying to get it back on track.  I started hating the dishwasher and if it weren't for the fact that it did clean extremely well, would have gotten rid of it.

Anyhow, my husband finally called a repair place but it was going to be outrageous for them to come and look so after some examination of the carriage, he discovered that the right side was missing this little wheel!  He found it here at amazon, replaced it and now I love my dishwasher!  What a cheap, easy fix...
