Abstract

A method of determining the laundry weight inside the drum (6) of a washing machine (1), wherein the drum (6) is mounted to rotate inside a wash tub (3) suspended in floating manner to a supporting frame (2) by at least one coil spring (4), the method including the steps of rotating the drum (6) at a predetermined angular speed; acquiring, instant by instant, the value of the length (H) of the coil spring (4) as the drum (6) rotates at the predetermined angular speed; and calculating the total weight (m tot ) of the laundry inside the drum (6) by extrapolating it from the mean value (Hm) of the length (H) of the coil spring (4) as the drum (6) rotates at the predetermined angular speed.
