More Information
Summary:The present disclosure concerns a method for detecting the status and failure of a door-lock device of a household appliance door, having two terminals and operating through different states. The method comprises the steps of applying a first control signal with a polarization, detecting the impedance at the terminals, and applying a second control signal, having opposite polarization to the first control signal, detecting the impedance to the ends of the terminals. In a reference table, the impedances at the ends of the terminals for each of the door-lock device states are provided. The method also compares the impedance values measured at the ends of said terminals with those of the comparative table, so as to detect the states of the door-lock device and any faults of the door-lock device according to the detected impedance values.
