The invention relates to a device for measuring the turbidity of the rinsing liquid in a dishwasher by means of a turbidity sensor. If it is provided according to the invention that the turbidity sensor is incorporated into the inlet flow of the circulation pump into the water drain shaft of the dishwasher and continuously measures the turbidity of the rinsing liquid, that the upper and lower spraying plane can be operated alternately, that a difference value can be derived from the turbidity values associated with upper and lower spray plane, that parameters for the quantity and the type of soiling can be derived from the turbidity values and the difference value and that the further rinse program can be established and controlled with these parameters, then, with low complexity, measurement values for the degree of soiling can be obtained, from which value parameters for the further course of the program can be delivered.
