• characterized in that the control apparatus is designed to determine the number of empty compartments in a group of successive empty compartments on the basis of the detection results of the washware sensor apparatus, and
• in that the control apparatus is also designed to automatically set the quantity of the final rinse liquid supplied to the spray nozzles per unit time as a function of the determined number of successive empty compartments;
• and
• characterized in that the control apparatus is designed
• to automatically set the quantity of final rinse liquid supplied to the spray nozzles per unit time to a predefined or predefinable first value when an occupied compartment enters the at least one final rinse zone;
• to automatically set the quantity of final rinse liquid supplied to the spray nozzles per unit time to a predefined or predefinable second value when the first compartment of a predefined or predefinable first number of successive empty compartments enters the at least one final rinse zone;
• and
• to automatically interrupt the supply of final rinse liquid to the spray nozzles when the first compartment of a second number of successive empty compartments enters the at least one final rinse zone, with the second value being greater than zero and less than the first value, and with the second number of successive empty compartments being greater than the first number of successive empty compartments.
