Abstract
A dishwashing machine is used for pre-rinse operation of soiled dishes. A cavity is configured and arranged to contain the soiled dishes. A nozzle is proximate the cavity and is in fluid communication with the cavity. An accumulator pan accumulates wash and rinse water including cleaning chemicals used in a previous cycle of the dishwashing machine. A fluid passageway interconnects the nozzle and the accumulator pan. A pump directs the accumulated wash and rinse water from the accumulator pan to the nozzle via the fluid passageway for pre-rinse operation of the soiled dishes in the cavity, and the nozzle directs the accumulated wash and rinse water into the cavity with the soiled dishes to assist in removing soil from the soiled dishes prior to a wash cycle of the dishwashing machine. The wash cycle utilizes fresh wash water.
