Abstract
In a commercial dishwashing machine the temperature of the final hot fresh rinsing water is sensed and sanitizer is injected into the rinsing water in a predetermined amount when the temperature of the hot rinsing water is sensed to be below a predetermined threshold minimum. The temperature sensing is accomplished with an electrical sensing device. The electrical temperature sensing device energizes the sanitizer for injection of sanitizer into the rinse water preferably within a predetermined temperature range of the hot rinsing water defined at a bottom limit by a threshold minimum and at an upper limit by a threshold maximum temperature.
