Abstract (en)
A dishwashing machine is described comprising an upper sprayer (6), a lower sprayer (4), a wash-liquid collecting sump (1), a washing pump (2), a supply circuit (5) to the upper sprayer (6), a supply circuit (3) to the lower sprayer (4) and an interception element (7') located downstream the pump (2) to exclude the supply circuit to one of the sprayers (4,6) if a washing cycle for a reduced crockery load is selected. According to the present invention an auxiliary hydraulic circuit (8) is provided between the pump delivery side (2) and the collecting sump (1), which is automatically inserted in case of a washing of a reduced load, and a setting element (9) located in said auxiliary circuit (8) to reduce water consumption but letting the pump (2) operate in a favourable work point and limiting the pressure on the interception element (7'). <IMAGE>
