Abstract
A method for an automated self-cleaning of a continuous dishwasher for items to be cleaned with at least one rinsing zone, at least one clear rinsing zone and also a transporter. Items to be cleaned are conveyed in the direction of transportation via the transporter. The continuous dishwasher comprises at least one fine filter with a back-rinser on at least one storage tank and also at least one device for emptying each of the storage tanks. The continuous dishwasher automatically carries out a self-cleaning cycle in which cleaning liquid located in each of the storage tanks is used several times in succession in the various zones for cleaning thereof. The cleaning liquid is circulated by means of circulating pumps in the respective storage tanks and supplied to spraying systems, which are already present in the respective zones, or to separate nozzles or nozzle heads for wetting the inner side of the faces delimiting the respective zone.
