2. FEATURES & TECHNICAL EXPLANATION  
2-1.FEATURES  
40%  
Jumbo drum  
LG’s jumbo drum can wash about 40% more load than  
conventional washing machine. A bigger drum improves the  
wash performance.  
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.  
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 to change the program  
during operation.  
Low noise speed control system  
By sensing the amount of load and balance, automatical  
distributes load evenly to minimize the spinning noise level.  
Auto Restart  
Although the washing machine is turned off by a power failure,  
it restarts automatically where it stopped when power is  
supplied again. And it will be the same the machine is  
unplugged and is plugged in again.  
Water circulation  
Spray 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 efficiently.
