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.

• Be sure the wire supports in undergarments are secure and will not become loose in the washer.

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 powdered 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 14-15)

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 woolens are lightweight, 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 (Skiing outfit, baby diaper, nappy automobile seat covers.)

Long laundry items

Use nylon bag nets for long, delicate 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 net bag can be purchased locally.

1) Using Water

Water Temperature

• The machine sets the appropriate temperature automatically according to the wash program .

You can override the preset selection by pressing the water temperature icon. Touch the arrow buttons up or

down until your desired temperature setting is displayed.

• 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.

2) 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

Your washing machine is designed for use with only High-Efficiency (HE) detergents. HE detergents are formulated specifically for HE machines and contain suds-reducing agents. Always look for the HE symbol when purchasing detergent. HE detergents produce fewer suds, dissolve more efficiently to improve washing and rinsing performance, and help to keep the interior of your washer clean. Using a regular detergent will cause unsatisfactory performance, oversudsing, machine build-up, and could damage the machine.

Using the Liquid Bleach Dispenser

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 premature dispensing of bleach. Do NOT add more bleach than is required for your particular load.

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

WARNING

Mixing chemicals like these can produce irritating and toxic fumes. Put the manufacturer’s recommended amount of undiluted liquid chlorine bleach into the bleach dispenser. During the final portion of the wash cycle, two sequential flushes of the dispenser put all the bleach into the wash load and completely flush the dispenser to eliminate the carryover of bleach to a subsequent load. Any liquid remaining in the bleach dispenser at the end of the cycle is water, not bleach. To prevent unintentional self-siphoning of the bleach, never fill the dispenser higher than the maximum fill level marked on the dispenser. When adding bleach to the dispenser, be careful to avoid spilling it into the laundry load or leaving droplets of bleach around the dispenser. These things will damage your laundry items.

Do NOT mix chlorine bleach with ammonia or acids, such as vinegar or rust / scale remover.

Using the Dispenser Drawer

ABOUT THE DISPENSER

The automatic dispenser consists of two compartments which hold:

• Liquid fabric softener.

• Liquid or powdered detergent.

All laundry products can be added at once in their respective dispenser compartments. They will be dispensed at the appropriate time for the most effective cleaning. After adding the laundry products to the dispenser, close the dispenser drawer. Close the dispenser drawer gently to avoid spilling or starting the siphoning action.

To add detergent, bleach, and fabric softener to the automatic dispenser:

❶ Open the dispenser drawer. ❷ Load the laundry products into the appropriate compartments. ❸ Close the lid slowly and smoothly to avoid spilling, splashing, or

premature dispensing of the contents.

NOTE: It is normal for a small amount of water to remain in the

dispenser compartments at the end of the cycle.

NOTE: Do not use powdered or liquid bleach in the dispenser drawer.

Adding Detergent

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 cycle. Either powdered or liquid detergent can be used, but the drawer insert must be removed to use powder.

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.

Adding Fabric Softener

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. If you use an ultra-thick fabric softener, you might want to dilute it with water so it dispenses easily.

Adding Wash Boost Additives

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 detergent buildup

In clothing and the washer

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.

3) Special Guide for Stain Removal
