Abstract:
A control for an electric water heater detects a condition of a heating element when the heating element is not being energized. A switching module is operable to interrupt power to the heating element, which de-energizes the heating element. A detector module detects the condition of the heating element when the heating element is de-energized. The detector module senses current flowing through the heating element and generates a detection signal that is indicative of the current.
