The present invention relates to a method for operating a laundry washing machine (1; 200) having washing tub (3) containing a washing drum (4) and a heating device (20) for heating liquid in the washing tub (3). The method comprises the steps of: introducing a quantity of water and a quantity of detergent in the washing tub (3) to form a washing liquid; heating the washing liquid; determining the temperature increasing speed (TS); comparing the determined temperature increasing speed (TS) with a threshold value (TV) and if the determined temperature increasing speed (TS) is above the threshold value (TV) establishing the presence of foam.
