We replaced our 30+ year old dishwasher with a new Bosch unit. Clearly technology has advanced over the years. The dishwasher is so quiet that we have to check the display to see if it is still running or has finished. We're also surprised at how much fits inside. We had to get a small, 18" dishwasher; much smaller than our old one. Yet it stil holds 2 days worth of dishes, so we have the same schedule of running the machine every other day. And so far, everything comes out perfectly clean.
