DISHWASHER PUMP AND MOTOR SIZE
While its often true that higher end machines have more insulation than cheaper models its not just insulation that makes the really quite machines quite. The really quite machines like WPs new series that has a filter have very small pumps and move much less water and have no grinder to dispose of chunks of food and get it out of the machine with every drain period. The new series is about as bad as the Frigidair machines and all the European machines. None of them come close to the ability to clean really dirty dishes and not smell bad in a few weeks. Unlike most of the machines we made over the last 30 years in this country.
