We replaced an ASKO dishwasher that expired after 28 years of service.  We opted for a model that would accept a front panel from our old ASKO dishwasher. Our new Bosh 800 series dishwasher is Very quiet while running.  It isn't easy to hear it, even standing next to it while in operation.  Cleaning results are superb.  Dishes and glassware are sparkling clean.
I recommend this unit with five stars.
