According to All-Clad, you will void the warranty instantly if you put any pans other than the stainless line into the dishwasher. Probably the other lines (except the LTD) can be put into the dishwasher with nothing other than cosmetic consequences. To some people, pretty pans are important, especially at All-Clad prices.
