Abstract (en)

A method for controlling the program of a washing machine having a water recirculation system comprises recording the amount of water supplied to the tub of the washing machine, assessing the amount of free water present in the tub, assessing the amount of water absorbed by the load by subtracting the amount of free water from the amount of water supplied to the tub, estimating a specific absorption of the load based on the water absorbed and on free water, calculating a load equivalent based on the specific absorption and on the amount of water absorbed by the load, such load equivalent being related to the load in the machine and being used for controlling the program thereof, a correction recursive function being used in calculating the load equivalent at least when the water recirculation pump is on. The method allows a quick evaluation of the water to be loaded in a washing machine and controls directly the electrovalve for loading water to the machine.
