1. A conveyor dishwashing machine, comprising:
a chamber for receiving wares, the chamber having an inlet end, an outlet end and multiple treatment zones therein including a washing zone configured for spraying washing liquid onto first wash items to be treated, and a final rinse zone which is located downstream, as viewed in an item transport direction, of the washing zone, wherein the final rinse zone is configured for spraying final rinse liquid onto the first wash items to be treated, the conveyor dishwashing machine having a transport apparatus for transporting the first wash items through the treatment zones in the item transport direction such that the first wash items are situated, at least in regions, in a main washing plane,
wherein at least one secondary washing plane is provided below at least one of the treatment zones, such that second wash items, which are located in the secondary washing plane, can be treated in the secondary washing plane, wherein the secondary washing plane is located at a height that is below a height of the main washing plane,
wherein the first wash items to be treated in the main washing plane are fed into the chamber through an inlet opening in the inlet end and fed out of the chamber through an outlet opening in the outlet end; and
wherein the second wash items to be treated in the secondary washing plane are loaded and unloaded through an opening that is separate from the inlet opening and the outlet opening;
wherein a treatment region of the secondary washing plane is physically sealed from the main washing plane such that washing liquid and rinsing liquid falling from the main washing plane does not enter the treatment region of the secondary washing plane.
