2. FEATURES & TECHNICAL EXPLANATION

2-1. FEATURES

The advanced Brushless DC motor directly drives the drum without belt and pulley.

Spray detergent solution and water over the load over continu.  
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 efficiently.

The Child lock prevents children from pressing any button to change the settings during
operation.

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.

By sensing the amount of load and balance, it evenly distributes load to minimize the
spinning noise level.

Automatically detects the load and optimizes the washing time.
