About the Thermostat
The thermostat monitors the dishwasher internal temperature and shuts off the heating element if the dishwasher overheats. If the thermostat is malfunctioning, it may shut off the voltage to the heating element circuit. However, this is rarely the case. Before replacing the thermostat check all the more commonly defective parts. If you have determined that all of the other components are working properly, test the thermostat by using a multimeter to check it for continuity.
