Abstract

A dishwashing machine has a tub (3), a fine-mesh filter (7) disposed in the tub upstream of a circulation pump (5), and a coarse-mesh filter (8) seated within the fine-mesh filter upstream of a water discharge pump (9). The coarse-mesh filter is susceptible to clogging by coarse impurities of relatively soft consistency, necessitating frequent removal and cleaning of the filter. According to the invention, spray jet means is provided for directing a jet of water coaxially onto the coarsemesh filter for cleaning it by the disintegration of soft matter collected therein. The spray jet means may take the form of an additional opening (10) in the bottom side of a rotatable irrigation arm, or of a jet nozzle (12) fixedly mounted in a horizontal position and cooperating with a deflector (13) for directing the water jet (11) issueing from the jet nozzle onto the coarse-mesh filter.
