Functionality of a Thermostat Limit Switch in Dishwasher

The functionality of a snap disc thermostat switch involves opening on temperature rise. This means that if the water temperature surpasses a safe threshold, the switch interrupts power to the dishwasher heating element, preventing overheating. Once the temperature normalizes, the thermostat’s contacts close, allowing power to resume to the heating element. However, if the switch malfunctions, it can lead to issues such as premature shutdowns or a failure to turn on, necessitating the replacement of the defective switch.Example of a dishwasher high limit switch
