Product review (1 stars): Expensive Detergent, Won't Clean, Low Capacity.
I contacted Bosch technical support to ask what I could be doing wrong concerning the dishwasher's repeated tendency to (a) not remove food that even a simple rinsing would remove, (b) bake food on that should have been cleaned. Their response was (1) Use Finish, the most expensive dish-washing detergent I know of, (2) clean the dishwasher regularly with Finish cleaner, (3) use Finish Rinse Aid, (4) don't put a lot of dishes in it. I do all of these regularly and find that if I don't rinse the dishes beforehand so well that I can't tell the difference between a clean and a dirty load, I will regret it. I am bewildered at the other reviews that claim that this machine removes food from the dishes. Over and over again, I find that I must either clean the dishes beforehand, or afterwards, and it's much harder afterwards because it's baked on. In general, I trust Consumer Reports, but experiences like this shake my confidence.

At least it's quiet.
