Abstract
A system and method are disclosed for cleaning articles within a chamber of a warewash machine. The warewash machine has a rinse sump for collecting a rinse agent dispensed into the chamber and a wash sump for collecting a wash agent dispensed into the chamber. The method includes a wash phase during which the wash agent is dispensed into the chamber during and an auxiliary rinse phase during which the rinse agent is dispensed into the chamber. The wash machine includes a controllable deflector for directing the wash agent to the wash sump during the wash phase and the rinse agent to the rinse sump during the auxiliary rinse phase. The method also includes a final rinse phase during which water from an external source is dispensed into the chamber. The controllable deflector direct the water dispensed during the final rinse phase to the rinse sump such that the water combines with the rinse agent therein. The rinse agent is re-used during at least one subsequent auxiliary rinse phase.
