Abstract
The device comprises at least one electrical air pressure threshold sensor, with a body which has an inlet connector; a support structure intended to be fixed in the machine, and to which the body of the pressure sensor is fixed; and at least one duct having one end coupled to the inlet connector of the pressure sensor, and the other end extending into the washing chamber or tub of the machine in such a way that when the level of the washing water in the chamber or tub increases, the water is capable of causing air to be trapped in the duct. The least one duct comprises a length of flexible tube, coupled to the inlet connector of the associated pressure sensor and curved and joined to the support structure in such a way as to form a loop which extends higher than the body of the pressure sensor, and which then continues downwards in the direction of the washing chamber or tub.
