1. A method for monitoring a solenoid valve comprising:
a movable member which extends in the conduit and for which a current position can be regulated in order to control a current flow rate of fluid that can flow in the conduit;
an electric motor arranged to cause the movable member to move so as to give it its current position;
the monitoring method comprising regularly repeated monitoring stages and each comprising the steps of:
driving the electric motor to modify the current position of the movable member;
evaluating a monitoring value representative of an inrush current of the electric motor during the driving step;
comparing the monitoring value with at least one first predetermined threshold and, if the monitoring value is greater than said first predetermined threshold, implementing at least one corrective action to avoid a blockage of the solenoid valve, the at least one corrective action comprising a corrective action consisting in increasing a supply voltage of the electric motor of the solenoid valve.
