Abstract

A device for determining a dirt load in a rinsing or detergent solution in a water-conducting household appliance includes a sensor configured to execute a near-infrared spectroscopy for acquiring a spectral measured value of a dirt component in the rinsing or detergent solution in the water-conducting household appliance. A determination unit determines the dirt load of the rinsing or detergent solution on the basis of the acquired spectral measured value of the dirt component in the rinsing or detergent solution, and an adjustment unit adjusts a wash parameter of a current wash program in response to the determined dirt load.
