Care Labels

Sorting

Check before Loading

Loading

Pretreatment on stains or heavy soil

WARING

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.

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, Nappies
Lint Collectors Synthetics, Corduroy, Permanent Press, Socks

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 tissue in pockets.

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.

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 Start button and
submerge additional items. Close the lid and press Start button again to restart.

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.

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 textiles(skiing outfit, baby's nappy, automobile seat covers)

Long laundry items

Use nylon nets for long, DELICATES items. For laundry with long strings or long length, a net will prevent
tangling during washing. Fasten zippers, hook, and strings to make sure that these items don't snag on
other clothes.

Nylon net is not supplied by LG.

Choosing the right Detergent

Attention

This machine detects the quantity of laundry automatically, then sets the WATER LEVEL.
When you select a wash program, the WATER LEVEL will be shown on the control panel.
The following table shows the amount of water.
When the WATER LEVEL is automatically detected, it may differ depending on the quantity
of laundry even though the same WATER LEVEL is indicated on the control panel.

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.

Follow the Detergent package directions. Using too little Detergent is a common cause of laundry problems.
Use more Detergent if you have hard water, large loads, greasy or oily soils or lower Water Temperature.

We recommend the use of domestic Detergent, (powder, liquid or concentrated). Soap flakes or granulated soap
powders should not be used in your washing machine. When washing woolens remember to use Detergent
suitable for washing woolens.

The machine sets the appropriate temperature automatically according to the wash program .
You can change the Water Temperature by pressing the WATER TEMP. button.
The temperature of the water impacts the effectiveness of all laundry additives and therefore, the cleaning results.
We recommend temperatures of:

- HOT 49~60 ...(120-140 ) White items, diapers, underclothing and heavily soiled, colorfast items.

- WARM 29~40 ...(85-105 ) Most items

- COLD* 18~24

...(65-75 ) 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

...(65 ) 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 ...(80-85 ).
If the temperature of the water in the tub is too cold for your hands, the Detergent will not activate and clean
effectively.

Using the Liquid Bleach Dispenser

Using the Dispenser Drawer

The bleach dispenser automatically dilutes and dispenses
liquid chlorine bleach at the proper time in the wash cycle.

1. Check clothing care labels for special instructions.

2. Measure liquid bleach carefully, following instructions on the
bottle.

Never pour undiluted liquid chlorine bleach directly onto clothes
or into the wash basket.
Do not pour powdered bleach into bleach dispenser.
Avoid overfilling or splashing when adding bleach to the
dispenser. The maximum capacity of the bleach dispenser is
one cup of bleach per wash cycle. Overfilling could result in
early dispensing of bleach.

3. Before starting the washer, pour measured amount of bleach
directly into bleach dispenser. If you prefer to use powdered
bleach, add it into the wash basket directly before adding clothes.

Do not mix chlorine bleach with ammonia or acids
such as vinegar and/or rust remover. Mixing can
produce a toxic gas which may cause death.

The dispenser drawer contains three compartments:

Liquid Fabric Softener
Liquid or Powder Detergent
Liquid Wash Boost Additives

The dispenser automatically dispenses additives at the
proper time in the wash cycle.

1. Slowly open the dispenser drawer by pulling the drawer out

until it stops.

2. After adding laundry products, slowly close the dispenser

drawer. Closing the drawer too quickly could result in early
dispensing of additives.

Avoid overfilling or splashing when adding laundry products
to the dispenser. Doing so could result in early dispensing of

laundry products.
At the end of the cycle, you may see water in the
compartments. This is part of the normal operation of the
washer.

NOTE: Do not use bleach in the dispenser drawer.

14

Adding Detergent

Adding Fabric Softener

Adding Wash Boost Additives

Add measured detergent to the detergent compartment of
the dispenser drawer.

Do not exceed the maximum fill line.

Detergent is flushed through the dispenser at the
beginning of the wash phase. Either powdered or liquid
detergent can be used.

Detergent usage may need to be adjusted for water
temperature, water hardness, size and soil level of the
load. Avoid using too much detergent in your washer, as it
can lead to oversudsing and detergent residue being left
on the clothes.

If desired, pour the recommended amount
of liquid fabric softener into the left-hand
compartment. Use only liquid fabric softener.

Dilute with water to the maximum fill line.

Do not exceed the maximum fill line.

Overfilling can cause early dispensing of the
fabric softener, which could stain clothes.

NOTE : Do not pour fabric softener directly on the wash load. It

may stain the clothes.

The Wash Boost dispenser may be used to
clean heavily soiled or stained garments
more efficiently.

If desired, place the additives for the
wash Boost setting in the right-hand
compartment. Use only liquid additives.

Do not exceed the maximum fill line to avoid

Overfilling can cause early dispensing of
presoak additives, which could result in
damaged clothes.

NOTE : Do not pour additives directly on the wash load. It may stain the clothes.clothes.
