I have a Bosch dishwasher, it is 3 years and a half years old. Set on the 2 and a half hour cycle it runs as normal up to the 2 hour mark. Then there is a click and it shuts off completely. It wont turn on again at the machine. It has to be turned off and then back on at the main switch on the wall, which appeared very warm to the touch. It then continues as normal to the end of the cycle. The main switch returns to normal during this last half hour.
