Abstract

The device comprises a solenoid valve of the proportional type (5), connected to the decalcifying device (3) and able to control the flow of water supplied to the washing chamber or tank (WT), and a control unit (CU, 7) able to drive said proportional solenoid valve (5) in a predetermined manner in such a way as to cause variations in the flowrate of the water supplied to the washing chamber or tank (WT), causing corresponding variations in the hardness of the water flow supplied to said chamber or tank (WT).
