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.
Direct Drive System
The advanced Brushless DC motor rotates the Drum
directly without belt and pulley.
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.
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.
Auto Restart
Auto Restart allows the program to restart all by itself in case
of power failure. It does from the stage where it stopped. It will
be also the same when washer is plugged in after unplugging.
