LG WD1070FH User manual

Jumbo drum
LG’s jumbo drum can wash about 40% more per load than
conventional washing machine. A bigger durm 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, evenly
distributes load to minimize the spinning noise level.
Auto Restart
Although the washing machine is turned off by a power failure,
it restarts automatically in its stopped process when power is
supplied again. and it will be the same when the machine
unplugged in operation 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 water supply is stopped, then washing program proceeds.
Spinning does not proceed until the water in the tub reduces to a certain level.

❋ Pre Wash : If the laundry is heavily soiled, “Pre Wash”course is effective. Pre Wash is available in Coloureds, Whites and
Synthetic Program.
❋ Eco : By selecting Eco function, the water temperature is reduced and washing time is lengthened. So you can economize in your
consumption of energy.
❋ Rinse+ : If you wish to rinse more, the Rinse+ function will remove any trace of detergents.
❋ Bio : If you want to elimenate protein stains (milk, blood, chocolate...), you may select Bio function by pressing the option button.
❋ You can select Bio function and Eco function when temperature is higher than 60˚C in Whites, Coloureds and Synthetic.
