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 .
