You look at higher-end dishwashers, and they all seem the same. They have stainless tubs, more cycles than ever and have decent to unbelievable quietness. In fact, it may be a bummer to replace a dishwasher, but the new ones are much quieter.
It wasn't always this way. Bosch and Miele changed the market in the early 1990s with a better dishwasher. For awhile, they owned the premium dishwashers. American companies like KitchenAid responded with competitive products years later.
