Abstract

The present invention is a method for controlling a dispenser reversibly positioned in a dishwasher. The dispenser or dishwasher is configured with light transmission and receiving units. Light pulses are transmitted into the interior of the dishwasher and received by the receiving unit. The time difference (tI2−tI1) between the pulses is determined and that time difference is used to encode an information item or a portion of an information item. Such information items include a control signal, a measured value, an operating state of the automatic dishwasher and/or of the dispensing apparatus.
