I purchased my Bosch dishwasher because my 10 year old dishwasher stopped working. I knew that Bosch was a high quality appliance so I decided for their model. Once installed, I don't even know when it's working. It's so quiet that I thought it wasn't working when I turned it on the first time. You could hear the water swishing with my old dishwasher, not this one!!!!  You can barely hear it when you put your ear up to it.  The various cycles available are perfect. I couldn't be happier.
