Abstract
A warewash machine includes a rinse sump and a wash sump. A controllable deflector, under control of a control module, directs wash agent dispensed during a wash phase to the wash sump, directs rinse agent to the wash sump for a predetermined period of time after initiation of an auxiliary rinse phase, and directs the rinse agent to the rinse sump after the predetermined period of time and for a remaining duration of the auxiliary rinse phase. The controllable deflector directs water dispensed during a 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.
