I went into the local Lowes to dishwasher shop and just minutes earlier someone had returned a Bosch unit because it was too tall for their countertop. They gave it to me for 60% off because they didn't want to deal with the return. I do know it's practically silent, because I hear beeps when it's done and never heard it running. My wife loves it, I have no opinion because I don't use it.
If you give me an email address, I can send you dishwasher ratings from a highly regarded source.
