Abstract (en)

[origin: EP2607542A2] A laundry treating appliance (10) may have a rotatable drum (16) defining a treating chamber (18) for receiving a laundry load, a motor (88) rotatably driving the drum (16), and a controller (96) controlling the operation of the motor (88). The laundry treating appliance (10) may be operated by accelerating the drum (16) with the motor (88) toward a final speed greater than a satellizing speed, determining a mass value indicative of the mass of the rotating drum (16) and contents within the treating chamber (18) during the accelerating, determining a current rotational speed during the acceleration, calculating a force value indicative of a force acting on the drum based on the determined mass value and the current rotational speed, comparing the force value to a reference force value, and repeating the determining, calculating, and comparing during the acceleration, and ceasing the accelerating when the force value obtains a predetermined relationship with the reference force value.
