Abstract
A method and appliance for determining the angular position of a laundry drum and a power consumption of an electric motor driving the drum to derive therefrom a laundry weight in the drum includes directly driving the drum with the motor from a lower laundry position to a raised position where a laundry center of gravity is offset from a rotation axis to produce a loading weight from the driving current of the electric motor measured when the raised position is reached. Alternatively or additionally, the drum is turned until the controller detects a power consumption of the electric motor corresponding to a stored maximum current value to derive a weight of the laundry from a signal corresponding to the angular distance. The controller stores a predetermined, defined maximum current value and measures a power consumption of the electric motor.
