WE HAVE HAD A NUMBER OF DISHWASHERS IN THE PAST AND ALWAYS HAD PROBLEMS. ABOUT 10 YEARS AGO WE PURCHASED A BOSCH AND NEVER HAD ANY PROBLEM WHATSOEVER.WHEN WE REMODELED OUR KITCHEN WE PURCHASED ALL NEW APPLIANCES AND NEVER CONSIDERED ANYTHING BUT BOSCH.WHEN  WE FIRST USED OUR DISHWASHER WE ACTUALLY HAD TO OPEN IT TO SEE IF WAS WORKING BECAUSE IT WAS SO QUIET. THANK YOU BOSCH.
