Whirlpool Dishwasher continuously blinking Cleaning Light

Has anyone with a Whirlpool DU1100XTPTA or a DU1055 (same tech) ever had the cleaning light blink continuously and nothing else on the washer would work? I have shut off the power for a time. No help. Understand there is a reset procedure and would like to try that but I do not know it??? Looking for any suggestions from anyone who knows of or has had such a problem and learned how to clear it up???
