> Why don't they? Another guess might be noise. Grinders are noisy and Bosch dishwashers are dead silent. I have a Benchmark series Bosch and it cleans dishes better than any I've ever had. I think a major factor is the built-in water softener. I have hard water, and soft water is key for allowing detergents to properly work.
