(57) A system for the supply and the dosage of water in a dishwashing machine comprising
a washing tub, a water decalcifier device and a metering container to which water
required for machine operation is supplied, by means of a supply tube and a supply
valve, at least two metering chambers being present in said container, having two
outlets, the first outlet allowing the discharge of at least a first water volume
contained in the first metering chamber, and the second outlet allowing the discharge
of at least a second water volume from the second metering chamber. According to the
invention, the container (1;101) has a section (V3;V103), which communicates through
proper hydraulic means (19;119) with the first metering chamber (V1;V101) and the
second metering chamber (V2;V102), and that in said section (V3;V103) a level sensor
is arranged, in particular of the float type (12;112), in order to detect the performed
water discharge at least from the section (V3;V103), and that the first metering chamber
(V1;V101) and the second metering chamber (V2;V102) can be discharged into the tub
independently from each other.
