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.

2-2.DETERMINE WASHING TIME BY FUZZY LOGIC
