Question: what is the difference in the bosch series dishwashers?
Answer: The Bosch 500 series has more cycles like EcoClean which maximizes energy efficiency and SpeedPerfect for a faster wash. You also pick up a third rack for cutlery which adds more space in the dishwasher itself. At 42 decibles, this series is 20% quieter than the 300 series and 70% quieter than the Ascenta.
