2. FEATURES & TECHNICAL EXPLANATION
2-1.FEATURES
40%
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.
