    • A method for determining a linen mass (M) through a washing machine (1) or dryer, with an electric motor (14) connected with a linen drum (5) for containing the linen, comprises:
      A) performing a first sequence of consecutive inrush steps, each inrush step comprising:
      - actuating a motor (14) of the washing machine (1) to accelerate the linen drum in rotation from an initial speed (v_init) equal to zero to a maximum predetermined speed (v_max), with a predetermined acceleration (STP_1),
      - upon reaching the maximum predetermined speed (v_max), slowing down the motor so as to make the linen drum (5) decelerate until reaching the initial speed (v_init) again, which is equal to zero,
      - in a detection time interval during the acceleration of the linen drum in rotation from the initial speed (v_init) equal to zero up to the predetermined maximum speed (v_max), detecting the inrush current (I_inrush) absorbed by the electric motor (14), the rotation speed (v) of the electric motor (14), and the time (t) (STP_2),

      B) calculating for each individual inrush step a rotational power parameter (P) generated by the electric motor (14) depending on the inrush current (I_inrush) (STP_3),
      C) calculating for the entire first sequence of consecutive inrush steps an average value (P_avg) of the rotational power parameters (P) calculated for the individual inrush steps (STP_5),
      D) determining the mass (M) of the linen in the linen drum (5) depending on the average value (P_avg) of the rotational power parameters (P) and predetermined parameters (P_0, A) characterizing the washing machine (1) (STP_13).

    • A household appliance (1), in particular a washing machine or washer-dryer, comprises a housing (2) with an outer wall (3) forming an outer surface (4), a treating seat (5) formed in or at the housing (2) and adapted to accommodate or support household products in a treating position (6), a treatment device (7) arranged inside the housing (2), a treatment detector (8) configured to detect a value of a treatment parameter, an electronic control system (10) in signal connection with the treatment device (7) and with the treatment detector (8) and configured to control the treatment device (7) depending on a treatment program and depending on the value detected by the treatment detector (8), a user interface (11) in signal connection with the electronic control system (10), in which the user interface (11) comprises an ON and OFF button (12), a first execution button (13) for a preset fixed treatment program, a second execution button (14) for a versatile treatment program which is preset with treatment parameters which can be set by the user, a coupling button (15), the activation of which carries out a wireless communication connection of the electronic control system (10) with an external electronic device (52), which is separate from the household appliance (1), for selecting and setting settable treatment parameters of the versatile treatment program by means of the external electronic device (52).
