Abstract

It is described a method for verifying the laundry load conditions in a washing and/or drying machine, comprising a drum containing the laundry, rotated by a motor (M), wherein a high spin speed (MC) is gradually reached during an operating phase; the main characteristics of said method consists in the fact that before reaching said high spin speed (MC) the load entity is verified and if the load exceeds a predetermined mass, also the load balancing conditions are verified, and that, in order to avoid any risks for the mechanical structure of the machine, the maximum spin speed (1400 rpm) is inhibited if a load higher than said predetermined mass and an out-of-balance condition of said load are detected.
