A household appliance, such as a dishwashing machine (1), has an inlet hose (9) which is connected by way of a machine-controlled electromagnetic inlet valve (12) to a mains stop cock (4), the valve being controllable by a program control device of the machine. A mechanically actuable stop valve (13) is arranged in series with the inlet valve (12) at the stop cock (4) and is held in an open rest state by a permanent magnet, a spring or the like. The stop valve (13) is closable by a pressure element which is connected by way of a duct (19) to a water level responsive pressure generating chamber (21) of the machine, of a level-regulating vessel (22). The inlet hose (9) opens free of valve means into an inlet (10) of the machine, and may be surrounded by a leakage water hose 23 leading to a collecting trough 17. A float 18 may be provided which is actuable by leakage water to open switch 16, thus closing inlet valve 12. <IMAGE> |
