Load balancing system
GB
Before every spin cycle, to avoid excessive vibrations
before every spin and to distribute the load in a uniform
manner, the drum rotates continuously at a speed which
is slightly greater than the washing rotation speed. If,
after several attempts, the load is not balanced correctly,
the machine spins at a reduced spin speed. If the load is
excessively unbalanced, the washing machine performs
the distribution process instead of spinning. To encourage
improved load distribution and balance, we recommend
small and large garments are mixed in the load.
