Abstract: The invention relates to a method of operating a dishwasher with a central control unit, by measuring the turbidity of the rinsing liquid and establishing the course of the program as a function of the turbidity of the rinsing liquid. In a pre-rinse operation, measurement values determined by a sensor system are derived from the soiling of the rinsing liquid and supplied to the control unit, which calculates therefrom associated parameters for the further course of the program and establishes the latter correspondingly.

Abstract: The invention relates to a method of operating a dishwasher with a central control unit by measuring the turbidity of the rinsing liquid and establishing the course of the program as a function of the turbidity of the rinsing liquid, the program beginning with a pre-rinse program step. In order to achieve a completely automatic operation, data for the further course of the program are calculated in the pre-rinse program portion with determined measurement values of turbidity and evaluation thereof.

Abstract: 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.

Abstract: A dishwashing machine having a washing chamber, a wash pump arranged to be driven by an electric motor for pumping up wash water from a wash water tank in the washing chamber and a control unit for controlling the washing cycle of the machine. The control unit is capable of detecting at least one working parameter of the electric motor of the pump, such parameter being linked to one or more parameters of the washing cycle and being used for controlling such cycle.
