Abstract

The invention relates to a control system for a solenoid valve of a domestic appliance, comprising a switch for regulating the current of the solenoid valve, a control unit for detecting a fault of the switch, and a safety circuit for monitoring the control unit for errors, wherein the safety circuit comprises a filter element that allows a certain frequency range to pass through. By means of the condition monitoring and a corresponding control of the switch by the control unit in the event of a switch having a fault, it is possible to prevent the solenoid valve from remaining open and gas from exiting with a short-circuit of the switch.
