Two things that I really like about the Bosch is that you can't hear it. I'm not saying it's quiet, I'm saying you can't hear it at all unless you are listening real closely. We have the stainless one, with the hidden controls so you can't see the lights unless the door is open. I have opened it more than once after my wife started a load, not realizing that it was running.
I also like that it heats the water to 180 degrees. I know that anything that comes out is not just clean, it's sterilized.
You are so right about the Bosch dishwashers. I’ve installed more than ten in the last 2 or 3 years. You can’t hear the Bosch. Hands down the most quiet.
