We have had the top-of-the-line Miele dishwasher and there is no comparison, especially when it comes to customer support and the company behind the product.  The Miele was very expensive to purchase and extremely expensive to repair every 2-3 years.  Miele quit standing behind their failed product which had problems routinely.  It is now Bosch forever for us and Miele never again.  Miele was not even courteous or nice about it, but nasty and lost our records unexplainably.  The good news is that it forced us to try Bosch and we could not be more pleased with the change.  We now have three Bosch diswashers in our immedite family and all are excellent machines and good experiences.
