Abstract

1. A method, utilizing a force couple signal, for ascertaining the level of water in the tub (10) of a washing machine with a perforated drum (12) containing the washing and adapted to rotate within the tub, characterized in that the variations in the friction force couple opposing the rotation of the drum (12) are measured while the frum is turning at constant speed.
