Shut off designated Dishwasher breaker ... Needed to disconnect water Line, drain line and disconnect electric and pulled out dishwasher from under counter.
open door remove inside fan cover using needle nose pliers, remove hoses from Assembly ... remove side cover ... disconnect associated connectors. Remove Assy-Case Brake from left side of unit and reinstall replacement.
Sally helped me diagnose issue and tech support helped me install. (Sally also sent me a manual which was extremely helpful)
Thanks Much!
