Direct Drive System
The advanced Brushless DC motor directly drives the drum without belt and pulley.
Built-in Heater
Child Lock
The Child lock prevents children from pressing any Buttons to change the settings during
operation.

More economical by Intelligent Wash System
Intelligent Wash 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.

consumption.
Low noise speed control system
By sensing the amount of load and balance, it evenly distributes load to minimize the
spinning noise level.

6 motion
Washer is able to perform various drum actions or a combination of different actions
depending on the wash program selected.
Combined with a controlled spin speed and the ability of the drum to rotate both
left and right, the wash performance of the machine is greatly improved, givong
you perfect results every time.
