A system (1) for controlling wash water hardness in a washing machine, in particular a dishwasher, comprising a water softening device (2) with a first container (3) containing resins (R), which reduce their softening capacity as a function of the volume of the treated water, a second container (4) containing a regenerating agent of said resins, a sensor (5) for detecting the state of the resins (R), first means (7,9;7A,9) for supplying wash water to be softened through said softening device (2), said system provides at least a water intake step from the water system directly to the washing tub (8) for mixing with the wash water from the softening device (2). The invention is featured in that it provides second means (10,A;C,10A) for supplying a quantity of water from the water system directly to the washing tub (8) depending on the water hardness detected by the sensor (5) for detection of the resins state (R;RC). <IMAGE> |
