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.

1. A wash machine for cleaning articles, wherein operation of the wash machine is controlled by a control module operable to initiate various phases of a cleaning process administered by the wash machine, the wash machine comprising: a chamber into which articles are placed for cleaning;a dispense module that dispenses a wash agent into the chamber during a wash phase, dispenses a rinse agent into the chamber during an auxiliary rinse phase, and dispenses water from a source external to the wash machine into the chamber during a final rinse phase, the wash phase occurring in the cleaning process prior to the auxiliary rinse phase, and the final rinse phase occurring after the auxiliary rinse phase;a rinse sump that collects a rinse agent dispensed into the chamber during the auxiliary rinse phase;a wash sump that collects the wash agent dispensed into the chamber during the wash phase, wherein the rinse sump comprises a first overflow drain into the wash sump and wherein the wash sump comprises a second overflow drain through which fluids in the wash sump are communicated to a sewage facility;a control module; anda sump diverter configured to direct fluid in the chamber to one of a wash sump or a rinse sump under control of the control module,the control module configured to control the sump diverter to direct the wash agent dispensed during the wash phase to the wash sump, to control the sump diverter to direct the rinse agent to the wash sump for a predetermined period of time after initiation of the auxiliary rinse phase, to control the sump diverter to direct the rinse agent to the rinse sump after the predetermined period of time and for a remaining duration of the auxiliary rinse phase, and to control the sump diverter to direct the water dispensed during the final rinse phase to the rinse sump,wherein the rinse agent overflows from the rinse sump into the wash sump via the first overflow drain and wherein the rinse agents and the wash agent overflow from the wash sump via the second overflow drain. 2. A wash machine as defined in claim 1, further comprising: a pump configured to pump the rinse agent from the rinse sump to the chamber. 3. A wash machine as defined in claim 2, wherein the pump is configured to pump the wash agent from the wash sump to the chamber; the wash machine further comprising: a pump diverter controllable by the control module and configured to direct the wash agent contained in the wash sump to the pump during the wash phase and to direct the rinse agent contained in the rinse sump to the pump during the rinse phase. 4. A wash machine as defined in claim 1, further comprising: a pump configured to pump both the wash agent and the rinse agent to the dispense module. 5. A wash machine as defined in claim 4, wherein the wash sump comprises: a booster heater for heating the wash agent contained in the wash sump to at least a first predetermined temperature. 6. A wash machine as defined in claim 5, wherein the control module initiates the wash phase in response to determining that the temperature of the wash agent in the wash sump has reached the first predetermined temperature. 7. A wash machine as defined in claim 5, wherein the rinse sump comprises: a booster heater for heating the rinse agent contained in the rinse sump to at least a second predetermined temperature. 8. A wash machine as defined in claim 7, wherein the control module initiates the wash phase in response to determining that the temperature of the wash agent in the wash sump has reached the first predetermined temperature and that the temperature of the rinse agent in the rinse sump has reached the second predetermined temperature. 9. The wash machine of claim 1 wherein the wash agent is formed by combining at least one chemical product with water in the wash sump. 10. The wash machine of claim 1 wherein the wash agent is formed by combining a detergent with water in the wash sump. 11. The wash machine of claim 1 wherein the rinse agent is formed by combining water with at least one chemical product used to form the wash agent. 12. The wash machine of claim 1 wherein the rinse agent is formed by combining water with at least one of a wetting agent or a sanitizing agent. 13. The wash machine of claim 1 wherein the auxiliary rinse agent is formed by combining water with at least one chemical product used to form the wash agent. 14. The wash machine of claim 1 wherein the auxiliary rinse agent is formed by combining water with at least one part of a chemical product used to form a cleaning agent. 15. The wash machine of claim 14 wherein the auxiliary rinse agent is formed by combining water with at least one of a wetting agent or a sanitizing agent.
