Upper Dishwasher drawer has an error code on lights not listed in the manual. The first, second and fifth light is illuminated. If I clear the code and start the washer again, it runs for a short time and water remains in tub and then ends with same error code indicated. I recently had my kitchen drain serviced for a clog behind garbage disposal and wondered if that issue lead to this one. Also, when you run the bottom drawer a small amount of water is left in upper drawer. I was hoping to find more information how to get to the bottom of the issue before I called anyone.
