Abstract (en)
[origin: CN109208266A] The invention relates to a method for operating a water-bearing domestic appliance 1, comprising a pump 18 for conveying an aqueous liquid 7, a variable-speed permanent-magnet synchronous motor as a pump drive motor 26 and a control unit 8. The method comprises the steps of setting a pump speed n to a value nl, in which a nozzle pressure p of the pump 18 is not sufficient to build up a conveying flow Q; and measuring torque M of the pump 18 as a measure of idle torque M l. The invention also relates to a water-bearing domestic appliance 1 suitable for carrying out the method.
