Though our dishwasher was still functioning, it was aging and we thought we could do better.  We had no idea until we purchased our new Bosch.   We selected Bosch partly on the recommendation of our local appliance dealer whom we trust implicity.  Once again they gave us great advice.  Even though the new dishwasher fits into the old space, it seems as if I can put so much more into it.  It's so quiet I can hardly know it's on.  It cleans everything thoroughly and dries efficiently.  Ours has three drawers which i would recommend.  I didn't know that third drawer could be so useful.  And the option to load crystal stemware after a dinner party is an amazing time saver.  I can't say enough about our new Bosch dishwasher.  I LOVE IT!
