Anti Crease function
With the alternate rotation of the drum, creasing in the laundry is
minimized.

More economical by Fuzzy Logic System
FUZZY Logic System detects the amount of load and water
temperature, and then determines the optimum water level and
washing time to minimize energy and water consumption.

washing time to minimize energy and water consumption.
Child-Lock
The Child-Lock system has been developed to prevent children
from pressing any button (except Power button) to change the
programme during operation.

programme during operation.
Low noise speed control system
By sensing the amount of load and balance, this system
automatically distributes load evenly to minimize the spinning
noise level.
