Abstract:
1. A control apparatus for an electrical domestic appliance having a dangerous component potentially posing a danger to a user and a protection component for protecting the user against the danger posed by the dangerous component, the control apparatus comprising: a control device configured to monitor operating states of the dangerous component and the protection component, and to selectively activate and deactivate the protection component; and a protection device configured to prevent a deactivation of the protection component by said control device outside a deactivation operating range of the dangerous component in which deactivation is permissible; a protection-device monitoring device configured to initiate a deactivation of the protection component within a simulation operating range of the dangerous component, in which range the operating state of the dangerous component does not present a danger to the user and which range is outside the deactivation operating range; and said control device being configured to identify a malfunction of the protection device if the protection component is actually deactivated when deactivation of the protection component is initiated by the protection-device monitoring device.
