Abstract (en)

[origin: WO2012059349A1] The invention relates to a method for operating a water-conducting domestic appliance (1), in particular a dishwasher (2) having a circulating pump (15) and a water flow diverter (9) that is associated with the circulating pump (15), in particular arranged downstream of the circulating pump (15), and has at least one control element that can be adjusted by a motor in order to change the direction of flow of a liquid through the water flow diverter (9). According to this method, the water-conducting domestic appliance (1) is filled with a minimum amount of filling water that can be circulated by the circulating pump (15); during a first step, the water flow diverter (9) is checked for malfunctions, and during a second step, the pump is checked for smooth running to ascertain whether the minimum amount of filling water in the water-conducting domestic appliance (1) corresponds to at least the nominal amount of filling water required to ensure the smooth running of the circulating pump (15), wherein in order to check the pump for smooth running at least one operational parameter of an electromotor (16) that drives the circulating pump (15) is evaluated in order to ascertain whether it corresponds to a smooth running of the circulating pump (15). According to the invention, the pump is checked for smooth running or a refilling step is carried out in order to increase the minimum amount of filling water when there is no malfunction of the water flow diverter (9), and no check or refilling step is carried out when malfunction of the water flow diverter (9) is detected.
