Dishwasher with dirt discharge system

A dishwasher having at least one washing system configured as a recirculation loop, wherein the at least one washing system comprises a nozzle system having at least one washing nozzle for spraying washing liquid onto items to be cleaned, a washing tank for collecting at least a portion of the sprayed washing liquid, and a washing pump for feeding washing liquid collected in the washing tank to the at least one washing nozzle, and wherein a dirt discharge system associated with the at least one washing system is provided, wherein a tank cover screen is associated with the dirt discharge system, which screen is configured so as to separate dirt particles from the sprayed washing liquid that flows back into the washing tank due to gravity, wherein the dirt discharge system comprises a dirt collection region arranged at least regionally in the washing tank for collecting the dirt particles separated from the washing liquid by the tank cover screen, and wherein the dirt discharge system is fluidly connected to the dirt collection region, via which the dirt collection region can be emptied,

• wherein the dirt discharge system is associated with a separator apparatus configured so as to separate at least a portion of the washing liquid required to empty the dirt collection region and discharged together with the dirt particles from the dirt collection region from the dirt particles discharged from the dirt collection region and to return the separated washing liquid back to the water circulation of the dishwasher;
• wherein the separator apparatus comprises a collection container that is fluidly connected or connectable to the dirt discharge system, to which, upon emptying of the dirt collection region, the washing liquid with the dirt particles, which is required in order to empty the dirt collection region, is fed from the dirt collection region, wherein a screen system is associated with the collection container, with which screen at least a portion of the washing liquid required for emptying the dirt collection region and discharged from the dirt collection region together with the dirt particles is separated from the dirt particles discharged from the dirt collection region.
