Bought the dishwasher 3 1/2 years ago. Both the flow sensor and the heating unit which is incorporated in the pump housing are shot. Total for the troubleshooting, parts and installation of the parts comes to over$400 dollars. It had very good rating when I bought it. My neighbor has a bosch that is at least a year newer and they have had to repair it. Good over the short run but not very durable. I am junking mine.
