ABSTRACT:
A method for controlling the amount of water filled in a dishwashing machine through a normally closed valve (18) to carry out a duty cycle of the machine in which the water is sprayed onto the washload items by a circulation pump (10) driven by an electric motor (11). The water is put under pressure by the pump in an intermittent manner with an alternate sequence of pre-set operating periods (T) and pauses (S) during which the motor rotating speed is at its highest value (V.sub.1) and lowest value (V.sub.0), respectively. The valve (18) is opened in at least one subsequent pause (S) following a preceding period (T) in which the pressure of the water in correspondence of the pump (10) decreases below a pre-determined threshold value (P.sub.2).
