A method in order to assume a safe operating condition of a device of a domestic appliance circuit arrangement for operating a domestic appliance and domestic appliance

摘要

The adoption of a safe operating state by a device 5, in particular a door locking device 5, a domestic appliance, without too much effort with respect to the software are made possible. It is a method is provided, in which a main control unit 7 of the domestic appliance receives an input signal 51 and the door locking device 5 from a first operating state into a second operating state is transferred due to the input signal 51. It is a motor control unit 13 for controlling an electrical machine 12 are supplied with electrical energy of the domestic appliance. The main control unit 7 transmits a first control command to the engine control unit 13, which causes the engine control unit 13 for this purpose, the electric machine 12 to take into operation. According to satisfaction of a first predetermined criterion controls the engine control unit 13 a blocking circuit 36, and due to the blocking circuit 36 dependent on the activation is prevented, that the main control unit 7 the door locking device 5 of the second operating state in the first operating state.
