1st we took the inside washer arms out and made sure they were clean and not blocked by something . When That failed, I called a local appliance repairman . After 2 messsges and absolutely no return call, I went on line and googled what could cause the problem. It recommended replacing the pump motor assembly . So we decided to try it. Ordered part. Came very fast . I looked up instructions on you tube and we followed this and made the repair . Dishwasher is working correct and dishes are clean again . Frustrating because the dishwasher was purchased in feb 2011 so it was not that old . I wish they made quality products . Happy parts customer . Thank you
