I am very concerned with getting a quiet dishwasher. I am deciding between a Bosch and a Miele. Don't want to pay more than $1500 - so will not consider top of the line Mieles. Bosch lists the decibel level, so I can compare to other brands. But Miele has their own acoustic "rating" which seems quasi meaningless when comparing against non-Miele brands. How can I get the decibel level of Miele dishwashers?
