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, Chenile, Towels, Nappies, 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 tissue in pockets.

WIRE

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.

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

Light and Large-sized clothing

Clothes like downs and woollens are light weight, large and float easily.

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.

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.

Long laundry items

Use nylon nets for long, DELICATE 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.

Using Water

Amount of WATER LEVEL

•This machine detects the quantity of laundry automatically, then sets the WATER LEVEL and proper amount of Detergent.

•When you select a wash program, the WATER LEVEL and amount of Detergent (to be used) 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.

• The amount of a cup in the diagram is about 40g for concentrated Detergent.

Water Temperature

•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°C…(120-140˚F) White items, diapers, underclothing and heavily soiled, colorfast items.

- WARM 29~40°C…(85-105˚F) Most items

- COLD* 18~24°C…(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.

Attention

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.

Using Detergent

Detergent

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.

Choosing the right Detergent

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.

12

Using Detergent

How much Detergent

When you select a wash program the WATER LEVEL and the amount of Detergent (to be used) will be shown on the control panel. The amount of a cup in the diagram is about 40g for concentrated Detergent.

The correct amount of Detergent will vary depending on the amount of soil in your clothes (Jeans and work cloches may need more Detergent, while bath towels usually need less.).

For liquid and concentrated Detergents, follow the recommendations of the Detergent manufacturer.

Note: To check you are using the correct amount of Detergent, lift the lid of your machine about halfway through the wash. There should be a thin layer of foam over the surface of the water. Lots of foam may look good, but it does not contribute to cleaning your clothes.

No foam means not enough Detergent has been used; soil and lint can settle back on the clothes or the washing machine.

If excess Detergent is used, the rinse will not be as clean and efficient. Also, it could cause environmental pollution, so use it accordingly.

Adding the Detergent

Open the Detergent dispenser and deposit the appropriate amount of Detergent.

Some Detergents MUST be fully dissolved before adding to your machine to get the best wash results.

Check the instructions on the Detergent packet.

If you use powdered Detergent it is essential that the required amount be fully dissolved in very HOT water before being added to WARM or HOT water for the actual wash.

Pre-dissolving Detergent in WARM water when washing in COLD water can improve its performance.

Powder Detergent

Where you deposit the Detergent

Using Liquid Bleach

•Check clothing care label for special instructions and separate the laundry to be bleached

•Dilute liquid chlorine bleach.

•Measure the recommended amount of liquid bleach carefully following instructions on the bottle.

•Before starting the washer, pour measured amount of bleach directly into bleach dispenser. Avoid splashing or overfilling.

Powdered bleach should be mixed with water before pouring.

Bleach dispenser

( )

Attention

Never pour undiluted liquid bleach directly onto clothes or into the wash basket. This may cause change of color or damage the laundry.

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

Do not pour powdered bleach into bleach dispenser.

13

Using Fabric Softner

•Dilute fabric softener with water.

Undiluted fabric softener may result in spots that look like oil stains.

•Measure and add the recommended amount of fabric softener into the compartment marked with this

smbol().

Follow manufacturer’s direction.

Fabric softener is automatically dispensed in the final rinse.

If you want EXTRA RINSE, you must add fabric softener manually when indication beep rings in the final rinse. This maximize the fabric softener function.

Do not overfill. The dispenser hold max 35m. Never add more than 35m.

Overfilling can cause early dispensing of the fabric softener

which could result in stained clothes. A cup with a pouring spout will help you avoid spilling

Softener dispenser ( )

or

•The effect of adding fabric softener may vary according to its viscosity. The stickier fabric softener makes its effect the lower. For a sticky fabric softener it is recommended that it be diluted with water, then be manually put during the time when the washer beeps several times before the final rinse. This function informing correct time to dispense manually is optionally applied to some models. Please keep it in mind that fabric softener has to be diluted with water before dispensed and never poured directly on clothes.

Attention

Do not mix with Detergent or bleach.

Never pour fabric softener directly on clothes. It may stain them.

Do not stop the washer during the first spin for timely dispensing.

Option washing is not designed to be used with fabric softener dispenser.

Scrud (Waxy Build up)

Scrud is the name given to the waxy build-up that can occur within any washer when the fabric softener comes into contact with Detergent. This build-up is not brought about by a fault in the machine.

If scrud is allowed to build-up in the machine it can result in stains on your clothes or an unpleasant smell in your washer.

•Using fabric softener sparingly.

•When filling the dispenser, do not splash or overfill.

•Clean dispenser as soon as the cycle is finished.

•Clean your machine regularly.

•Cold water washing increases the chance of this build-up occurring. We recommend a regular WARM or HOT wash e.g. every 5th wash should be at least a warm one.

•Fabric softener of thinner consistency is less likely to leave residue on the dispenser and contribute to a build-up.
