Thanks for the tip. Hitting "heat dry/normal/heat dry/normal" in sequence, and then hitting "cancel" when all the lights lit up worked! This happened to us once before, last winter. We were told that we needed to run hot water in the sink to pre-heat the water so that the dishwasher did not think that the heating element had failed. This tip saved us an expensive visit by a Sears Technician. Sears would not give us this info over the phone. So much for customer service.
