IMPORTANT SAFETY INSTRUCTIONS
WARNING
To reduce the risk of explosion, fire, death, electric shock,
injury or scalding to persons when using this product,
follow basic precautions, including the following:
Children in the Household
This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental capabilities, or
lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a
person responsible for their safety. Children should be supervised
to ensure that they do not play with the appliance.

Installation
•Never attempt to operate the appliance if it is damaged,
malfunctioning, partially disassembled, or has missing or broken
parts, including a damaged cord or plug.
•This appliance should only be transported by two or more people
holding the appliance securely.
•Tighten the drain hose to avoid separation.
•If the power cord is damaged or the hole of the socket outlet is
loose, do not use the power cord and contact an authorized
service centre.
•Make sure the plug is completely pushed into the outlet.
•Do not install the appliance in a damp and dusty place. Do not
install or store the appliance in any outdoor area, or any area that
is subject to weathering conditions such as direct sunlight, wind,
rain, or temperatures below freezing.
•Ventilation openings must not be obstructed by a carpet.
•Do not plug the appliance into multiple socket outlets or extension
power cable.
•This appliance must be grounded. In the event of malfunction or
breakdown, grounding will reduce the risk of electric shock by
providing a path of least resistance for electric current.
•This appliance is equipped with a power cord having an
equipment-grounding conductor and a grounding power plug. The
power plug must be plugged into an appropriate socket outlet that
is installed and grounded in accordance with all local codes and
ordinances.

6
EN
•Improper connection of the equipment-grounding conductor can
result in risk of electric shock. Check with a qualified electrician or
service personnel if you are in doubt as to whether the appliance
is properly grounded.
•Do not modify the power cord provided with the appliance.
Operation
•Do not use a sharp object like drill or pin to press or separate an
operation unit.
•Keep the area underneath and around the appliance free of
combustible materials such as lint, paper, rags, chemicals, etc.
•Do not put animals, such as pets into the appliance.
•Do not leave the appliance door open. Children may hang on the
door or crawl inside the appliance, causing damage or injury.
•Use new hose or hose-set supplied with the appliance. Reusing
old hoses can cause a water leak and subsequent property
damage.
•Turn off water taps to relieve pressure on hoses and valves and to
minimize leakage if a break or rupture should occur. Check the
condition of the fill hoses; they may need replacement after 5
years.
•Never reach into the appliance while it is operating. Wait until the
drum has completely stopped.
•Do not put in, wash or dry articles that have been cleaned in,
washed in, soaked in, or spotted with combustible or explosive
substances (such as waxes, wax removers, oil, paint, gasoline,
degreasers, drycleaning solvents, kerosene, petrol, spot removers,
turpentine, vegetable oil, cooking oil, acetone, alcohol, etc.).
Improper use can cause fire or explosion.

7
EN
•In case of flood, disconnect the power plug and contact the LG
Electronics customer information centre.
•Do not use or store flammable or combustible substances (ether,
benzene, alcohol, chemical, LPG, combustible spray, insecticide,
air freshener, cosmetics, etc.) near the appliance.
•If there is a gas leakage (isobutane, propane, natural gas, etc.),
do not touch the appliance or power plug and ventilate the area
immediately.
•If the drain hose or inlet hose is frozen during winter, use it only
after thawing.
•Keep all washing detergents, softener and bleach away from
children.
•Do not touch the power plug or the appliance controls with wet
hands.
•Do not bend the power cable excessively or place a heavy object
on it.
•Do not put your hand, foot or anything under the washing machine
while the washing machine is in operation.
•The hands shall not be inserted into running water-extracting
drum.
•Make sure that drainage is working properly. If water is not
drained properly, your floor may get flooded.
•If, during spinning, opening the door does not stop the drum within
about 15 seconds, immediately discontinue operating the
appliance and contact your dealer or LG Electronics service
centre.

8
EN
•Do not use a plug socket and wiring equipment for more than their
rated capacity.
•When the air temperature is high and the water temperature is
low, condensation may occur and thus wet the floor.
•Wipe off dirt or dust on the contacts of the power plug.
•Under certain conditions hydrogen gas may be produced in a
water heater that has not been used for two weeks or more.
Hydrogen gas can be explosive under these circumstances. If the
HOT water has not been used for two weeks or more, prevent the
possibility of damage or injury by turning on all Hot water taps and
allowing them to run for several minutes. Do this before using any
electrical appliance which is connected to the HOT water system.
This simple procedure will allow any built-up hydrogen gas to
escape. Since the gas is flammable, do not smoke or use an open
flame or appliance during this process.
Maintenance
•Remove the power plug when you clean the appliance.
•Securely plug the power plug in the socket outlet after completely
removing any moisture and dust.
•Do not spray water inside or outside the appliance to clean it.
•Never unplug the appliance by pulling on the power cable. Always
grip the power plug firmly and pull straight out from the socket
outlet.
•Only qualified service personnel from LG Electronics service
centre should disassemble, repair, or modify the appliance.
Contact an LG Electronics customer information centre if you
move and install the appliance in a different location.

EN
Disposal
•Before discarding an old appliance, unplug it. Cut off the cable
directly behind the appliance to prevent misuse.
•Dispose of all packaging materials (such as plastic bags and
styrofoam) away from children. The packaging materials can
cause suffocation.
•Remove the door before disposing of or discarding this appliance
to avoid the danger of children or small animals getting trapped
inside.
For One Valve Model
•Do not connect to hot water supply.
