3-2. BEFORE STARTING TO WASH
Care Labels
• Look for a care label on your clothes.
This will tell you about the fabric content of your garment and how it should be washed.
Sort clothes into loads that can be washed with the same wash cycle, water temperature,
and spin speed.
Sorting
To get the best results, different fabrics need to be washed in different ways.
• SOIL (Heavy, Normal, Light) Separate clothes according to the type and amount of soil.
• COLOR (Whites, Lights, Darks) Separate white fabrics from colored fabrics.
• LINT (Lint producers, Collectors) Separate lint producers and lint collectors.
Lint Producers Terry cloth, Chenille, Towels, Diapers
Lint Collectors Synthetics, Corduroy, Permanent Press, Socks
Check before Loading
• Check all pockets to make sure that they are empty. Things such as nails, hairclips, matches,
pens, coins, and keys can damage both your washer and your clothes.
• Mend any torn garments or loose buttons. Tears or holes may become larger during washing.
• Remove belts, underwires, etc. to prevent damage to the machine or your clothes.
• Pretreat any dirt and stains.
• Make sure the clothes are washable in water.
• Check the washing instructions.
• Remove any paper or tissue in the pockets.
• WIRE
Loading
Do not wash fabrics containing flammable materials(waxes, cleaning fluids, etc.).
Load Size
The WATER LEVEL should just cover the clothes. Adjust the load size
accordingly. Loosely load clothes no higher than the top row of holes in the
washer tub. To add items after washer has started, press the Start button and
submerge additional items. Close the lid and press the Start button again to restart.
※Do not wash waterproofed fabrics (such as skiing outfits, diapers, or nappy
auto seat covers.)
Light and Large-sized clothing
Clothes like downs and woollens are light weight, large and float easily. Use a nylon net and
wash them in a small amount of water. If the laundry floats during the wash cycle, it may
become damaged. Use dissolved detergent to prevent the detergent from clumping.
※Do not wash water-proof textilles (Skling outfit, baby diaper, nappy automobile seat covers.)
Long laundry items
Use nylon bag nets for long, DELICATES items. For laundry with long strings or long length, a bag will prevent
tangling during washing. Fasten zippers, hooks, and strings to make sure that these items don't snag on
other clothes.
※The nylon washing bag is not supplied by LG.
Pretreatment on stains or heavy soil
• Pretreat shirt collars and cuffs with a pre-wash product or liquid Detergent when placing them in the washer.
Before washing treat special stains with bar soaps, liquid detergent or a paste of water and granular detergent.
• Use a pretreat soil and stain remover.
Treat stains AS SOON AS POSSIBLE. The longer they are left, the harder they are to remove.
(For more detail refer to page 13)
WIRE
WARNING
Fire Hazard
Never place items in the washer that are
dampened with gasoline or other flammable
fluids.
No washer can completely remove oil.
Do not dry anything that has ever had any type
of oil on it (including cooking oils).
Doing so can result in death, explosion, or fire.

10
Using Water
Using detergent/fabric softener
Recommended detergent
Make sure to use HE (High-Efficiency) detergent for Top loading washing machines. HE detergents dissolve
more efficiently and produce fewer suds to ensure efficient washing and rinsing. Use the correct amount of
detergent as indicated on the label of the detergent packaging.
Designed specially to use only
HE (High-Efficiency) detergent
Water Temperature
• The machine sets the appropriate temperature automatically according to the wash program .
You can override the preset selection by pressing the WASH/RINSE temperature. button.
• The temperature of the water impacts the effectiveness of all laundry additives and therefore, the cleaning results.
• We recommend temperatures of:
- HOT 120°F (120-140°F) White items, diapers, underclothing and heavily soiled, colorfast items.
- WARM 90°F (85-105°F) Most items
- COLD 66°F (65-75°F) Only very bright colors with light soil.
• When washing in COLD water additional steps may be needed:
- Adjust Detergent amount and pre-dissolve Detergent in WARM water
- Pretreat spots and stains
- Soak heavily soiled items
- Use appropriate bleach
* Temperature below 18°C (65°F) will not activate laundry additives and may cause lint, residue, poor cleaning, etc.
In addition, detergent manufactures and care labels define COLD water as 26~29°C...(80-85°F).
If the temperature of the water in the tub is too cold for your hands, the detergent will not activate and clean
effectively.
Note
If iron is present in the water the clothes may become an all-over yellow or they may be stained with brown or
orange spots or streaks. Iron is not always visible. Installation of water softener or an iron filter may be
necessary for severe cases.
Note
• Only use HE detergents, since using a regular detergent may produce excessive suds.
• HE detergents produce fewer suds, dissolve more efficiently to improve washing and rinsing performance, and
help to keep the interior of your washer clean.
• Use less detergent for soft water.
• Wipe up any spills immediately, as liquids could damage the finish and the control panel of the washing
machine.
• Using too much detergent can cause a build-up in the tub resulting in unsatisfactory performance and machine
malfunction.
• If you use a detergent that does not dissolve easily or a detergent with high viscosity, it will leave a residue on
the tub, which may not rinse properly.

11
Loading the dispenser
The detergent dispenser drawer of the washing machine has a
dispenser compartment for each detergent type. Add the
appropriate detergents into its respective compartments.
1 Pull out the detergent dispenser drawer.
2 Add the appropriate detergent to its allocated compartment.
- If you use a liquid detergent, check if the liquid detergent cup is in
place.
- If you use a powdered detergent, remove the liquid detergent cup
and put the powder in the main wash detergent compartment.
3 Close the detergent dispenser drawer slowly.
- Slamming the detergent dispenser drawer may result in the
detergent overflowing into another compartment or pouring into
the tub earlier than programmed.
Note
• It is normal for a small amount of water to remain in the dispenser compartments at the end of the cycle
