If you buy a Bosch dishwasher from Sears, Bosch will not service it, only Sears. They use different parts. Had a employee by a Bostich nail gun from the box store, had problems with it, took it to a Bostich service center, the service center said take it back where you bought it. He said, even though the model number was the same as their factory gun, they add a letter to the part number. He said the parts in the factory gun will not fit the big box gun. He took it to the big box store, after waiting 8 weeks for repairs, they called him and said that the model had been discontinued, and they would give him a prorated refund. So be very careful about buying tools from the big box stores.
