<p>The invention relates to a safety circuit for domestic appliances using water, particularly washing machines and dishwashers, with a program selector, a level switch in the washing or rinsing container and a leak detector in a water collecting trough. Safety can be increased and damage caused by fault occurring even when the domestic appliance is switched off can be prevented by the provision of an additional logic circuit continuously fed with mains alternating current which can be controlled by the program selector, the level switch and the leak detecting device, by the logic circuit switching on the process control to the power supply on the occurrence of predetermined trigger conditions and by the process control effecting predetermined switching processes, as a function of the prevailing trigger conditions, through components (e.g. pump) of the domestic appliance.</p> |
