The circuit features an additional logic circuit (LS) which is fed permanently by the ac mains and controlled by the program selector (PW), the level switch (WUS) and the leak display (LA). The circuit features an additional logic circuit (LS) which is fed permanently by the ac mains and controlled by the program selector (PW), the level switch (WUS) and the leak display (LA). In the presence of preset control conditions, the logic circuit (LS) connects the process control (PS) to the current supply. The process control (PS) introduces preset connecting processes in accordance with the prevailing control conditions via components (e.g. a pump) of the appliance.
