How do I reset my Quiet Partner 3?

From time to time my dishwasher goes dead on me. The power supply is always good and I have checked the TCO which is OK. How do I reset the machine? I have received conflicting advice such as Sani-Heated Dry-Sani, and Heated Dry-Normal-Heated Dry-Normal. Is there a tech sheet available?
