Abstract

The invention relates to a dishwashing machine with a lower and an upper spray arm and a circulating pump (1) for circulating operation of the rinse water and a wash liquor pump (12) in the sump (11) in the bottom of the rinsing reservoir for the removal by suction of the rinse water in the suction operation. The deposition of sludge in the sump of the rinsing reservoir and the subsequent removal by suction of the dirt particles with the rinse water is achieved by a depositing and suction area and a separate circulating area in the sump of the rinsing reservoir.
