A washing and/or drying appliance (100) is proposed. The appliance comprises: an electric load (205), a driving arrangement (210,215,C) for driving the electric load (205), the driving arrangement (210,215,C) having first (T205,IN1) and second (T205,IN2) terminals coupleable, respectively, to a line terminal (TL) and to a neutral terminal (TN) providing a reference voltage (VCC), an inrush current limiting device (RFUSE; RNTC) and a switching device (RL; RL1) between the reference terminal (TN) and the second terminal (T205,IN2) of the driving arrangement (210,215,C), the switching device (RL;RL1) being operable in first or second states preventing or allowing, respectively, an electric current to flow through the inrush current limiting device (RFUSE, RNTC), and a sensing network (RPD) for sensing the first or second states of the switching device (RL; RL1) and for providing a corresponding state signal (SSTATE; S*STATE), the sensing network (RPD) having a first terminal (TRPD,1), and a second terminal (TRPD,2) coupled to a reference terminal providing a further reference voltage (GND) lower than the reference voltage (VCC), wherein, during sensing: in the first state of the switching device (RL; RL1) the reference terminal (TN) and the first terminal (TRPD,1) of the sensing network (RPD) being coupled to each other such that the first terminal (TRPD,1) of the sensing network (RPD) receives the reference voltage (V CC ) and the state signal (SSTATE; S*STATE) takes a first level (SSTATE,H) equal to the reference voltage (V CC ), in the second state the state signal (SSTATE, S*STATE) taking a second level (SSTATE, I; SSTATE,L) lower than the first level (SSTATE,H). |
