Disconnected power to the unit at the circuit breaker. Removed the bottom panel of the dishwasher. Used a stubby Phillip screwdriver to remove the single retaining screw holding the high limit thermostat against the bottom of the dishwasher tub. Not only was the thermostat burned out, one of it's electrical connectors was also destroyed. Removed the tape holding the cable bundle together so that I could work on the quick disconnect plug outside of the unit. One end of the quick disconnect plug was completely burned through and needed to be replaced. After doing the necessary electrical repairs and assembling the new thermostat into position I applied power and everything worked fine. It helped having a picture on your website that I could use to identify the correct replacement part.
