A water heater fails to produce hot water due to specific mechanical, electrical, or structural malfunctions. Electric models lose hot water when upper or lower heating elements burn out, thermostats fail, or circuit breakers trip. Gas units fail when the pilot light goes out, the thermocouple breaks, or the gas control valve malfunctions. Furthermore, heavy mineral sediment accumulation at the bottom of the tank creates an insulating barrier between the burner and the water, severely reducing heating efficiency and output. Verification: Flush sediment from the tank and test electrical components with a multimeter.
