Jumbo drum
LG’s jumbo drum can wash about 40% more per load than
conventional washing machine. A bigger drum improves the
wash performance.
More economical by Fuzzy Logic System
FUZZY Logic 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.
Child-Lock
The Child-Lock system has been developed to prevent
children from pressing any button to change the programme
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. It will be the same when the machine
unplugged and is plugged in again.

2-2.DETERMINE WASHING TIME BY FUZZY LOGIC
To get the best washing performance optimal time is determined by sensing of water temperature,
selected washing temperature and laundry amount.
2-3.WATER LEVEL CONTROL
This model adopts a pressure sensor which can sense the water level in the tub.
When the water level reaches to the preset level the water supply is stopped, then the washing program proceeds.
Spinning does not proceed until the water in the tub reduces a certain level.
2-4.THE DOOR CAN NOT BE OPENED
While program is operating.
While Door Lock light turns on.
