We recently replaced an older dishwasher with a new Bosch panel ready dishwasher. The cleaning performance of the dishwasher is very good, and much better than our older unit.  Dried peanut butter on knives still presents a challenge. Based on other reviews, we were expecting this dishwasher to be extremely quiet to the point of not being able to hear it. We were disappointed in the sound levels, and can easily hear it running through the cleaning cycles. It is much quieter than the old unit. Overall we are happy with the performance of the machine.
