There is only 1 thing I can attest to. It is an awesome dishwasher. Noise lever is NONE, and I have very good hearing. Dishes are impecably/pristine clean. There is only one problem and not with the dishwasher it's with the Cascade pods; the lining sometimes does not wash off and gets stuck to the bottom or left over in the cup where itnis inserted. Worry it may clog the system.
