Did you check to see if there was a recall on this particular model of dishwasher? It seems to me that this is either a manufacturing problem or an installation error, neither of which is Sears' problem. The house I live in has a dishwasher that is twenty years old, and I have no idea where it was purchased from...however, I can look at it and see who the manufacturer is and look inside at the plate for the model number and other pertinent information should I need replacement parts, or, were it newer, warranty information. I think I would take the matter up with the contractor or the manufacturer.
