ABSTRACT:
An external reset device that is operable in combination with an electric water heater is disclosed. The external reset device is attached to an element cover that is mounted to the water heater and conceals the water heater's control device, such as a manual reset thermostat. The external reset device comprises a bushing member and a key member attached to the element cover. The bushing member is aligned with a reset button on the control device. The key member is adapted for insertion into the bushing member to depress the reset button and close a switch, enabling the heating elements of the electric water heater to power ON and heat the water within the electric water heater.
