Abstract (en)
[origin: WO2016146313A1] The invention relates to a method for operating a washing machine (1), comprising a container (2), a drum (3) for accommodating laundry items (4), a drive motor (5) for the drum (3), an electrochemical sensor (9) in the container (2) for measuring an electrochemical signal in dependence on a composition of an aqueous liquid (7) in the container (2), and a control device (8), wherein the following steps are performed: (a) providing a detergent-containing aqueous liquid (7) in the container (2); (b) rotating the drum (3) in accordance with a predetermined motion program; (c) ending rotational motion of the drum (3) and allowing the detergent-containing aqueous liquid (7) to rest until a specified calmed state of the detergent-containing aqueous liquid (7) is achieved; and (d) measuring the concentration cten of a detergent in the detergent-containing aqueous liquid (7) provided in step (a) by recording and evaluating electrochemical signals of the electrochemical sensor (9) by using a relationship between electrochemical signals and detergent concentrations, which relationship is stored in the control device (8). The invention further relates to a washing machine (1) suitable for performing the method.
