Our previous Bosch Dishwasher lasted over 10 years which amazed me. So, when it was time to replace it, we again chose the Bosch 500 series. Wow! much improved functions and dish racks. didn't think we'd like the third rack for silverware and flat stuff but we were wrong! That's a great idea and save more lroom in the large bottom rack. Racks are adjustable and glide smoothly. It even tells us when we need to refill the rinse agent. A great new feature is to have the door pop open at the end of the cycle to further eliminate any moisture inside. We Love this new dishwasher and heartily recommend it!
