ABSTRACT:
A method is provided for regenerating a mass of active resin contained in a water softening device connected in the water filling circuit of a washing machine. The water softener device has an internal volume which is equal to the sum of the volume of the mass of resin plus a free volume, and is selectively supplied with both fresh water and brine through respective valves controlled by a program control device. The water softening device is supplied with a volume of brine during a first period of time, and is subsequently supplied with a complementary volume of water during a second period of time. The sum of the volume of brine, which is selected according to the hardness of the supply water, and the complementary volume of water is equal to the free volume of the water softening device.
