  • determining weight of a load of clothes being contained in a tub;

    braking the motor according to a slow brake logic if a interruption of the motor is ordered when the motor speed is less than or equal to a third predetermined speed(W3);

    selecting one of a plurality of rapid-brake logics on the basis of the measured weight of a load of clothes and braking the motor according to the selected rapid-brake logic if a interruption of the motor is ordered when the motor speed is greater than or equal to a third predetermined speed(W3) and a spin period is determined to be less than a predetermined period of time(E); and

    braking the motor according to the selected rapid-brake logic based on the measured weight of a load of clothes when the motor speed is greater than or equal to a third predetermined speed(W3) if a interruption of the motor is ordered after the spin period is determined to be greater than or equal to the predetermined period of time(E) and the motor power is turned off.
