nDirect Drive System
The advanced Brushless DC motor directly drives the drum without belt and pulley.
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, giving you
perfect results every time.
nTurbo Wash
Wash cycle in under 1 hour with energy and water saving.
(based on half of laundry)
nWater Circulation
Sprays detergent solution and water onto the load over and over.
Clothes are soaked more quickly and thoroughly during wash cycle.
The detergent suds can be removed more easily by the water shower during rinse
cycle. The water circulation system uses both water and detergent more ef ciently.

nTilted Drum and Extra Large Door Opening
Tilted drum and extra large opening make it possible to load and unload clothing
more easily.
nEmbossing drum & waved lifter
Embossing drum enhances the washing performance and reduces clothes damage.
The waved lifter spray and help clothes to enhance washing performance during
the washing cycle.
nAutomatic Wash Load Detection
Automatically detects the load and optimizes the washing time.
nBuilt-in Heater
Internal heater helps to maintain water temperature at its optimum level for selected
cycles.
nChild Lock
The Child lock prevents children from pressing any button to change the settings-
