Abstract
A door lock provides a restart lockout function for an electrical household appliance to prevent an automatic restart by closing the appliance door again after having been opened during operation of the appliance. The door lock comprises a locking device, which in a closed position locks the door and in an open position releases the door, and a restart lockout device, which in a release state enables operation of the appliance and in a lockout state prevents operation of the appliance. Upon a changeover from its closed position to its open position, the locking device brings the restart lockout device out of its release state into its lockout state.
