ABSTRACT:
A dispensing apparatus and method for dispensing detergent in a warewash machine. The rinse water spray system or an alternate water source is monitored to determine if water is being supplied to the warewash machine. Once water is sensed being supplied to the machine, the apparatus determines whether the water is being supplied for a rinse cycle or a fill cycle. The amount of detergent dispensed is controlled based upon the determination of whether the water is being supplied in a rinse cycle or a fill cycle. If the apparatus determines that the water is being supplied for a rinse cycle, a make-up amount of detergent is dispensed upon completion of the rinse cycle. If the apparatus determines that the water is being supplied for a fill cycle, the washtank is precharged with the desired concentration of detergent during the fill cycle.
