Check before Loading
Pretreatment on stains or heavy soil
WARNING
Loading
* 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.
• 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.
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.
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.
• 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
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.

Using Water
Water Temperature
Using the Dispenser Drawer
NOTE
NOTE
[ Minimum water amount ]
It depends on laundry load and washer model. If adding water manually at the beginning of a wash, the water
sensor will then allow the machine to start washing when the minimum amount of water has been added.
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.
• When washing in COLD water additional steps may be needed:
- Adjust Detergent amount and pre-dissolve Detergent in WARM water and add to the machine by hand.
- Pretreat spots and stains
- Soak heavily soiled items
- Use appropriate bleach
* Temperature below 18°C…(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°C…(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.
The dispenser drawer contains 2 compartments:
• Liquid Fabric Softener
• Liquid or Powder Low-Sudsing, High-Efficiency Detergent
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.
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 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.

Using Detergent
Using Detergent
Detergent
Choosing the right Detergent
How much Detergent
Adding Detergent
Follow the Detergent package directions. Using too little Detergent is a common cause of laundry problems as is if too
much detergent is used.
Only more Detergent if you have hard water, large loads, greasy or oily soils or lower Water Temperature.
We recommend the use of drum type, low sudsing high efficiency 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 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, and long term scrud build up.
Add measured detergent to the detergent compartment of the dispenser drawer.
Detergent is flushed through the dispenser at the beginning of the wash phase. Pre dissolved detergent can also
be added directly into the bowl by hand at this time.
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.

14
Using Liquid Bleach
Using Fabric Softener
Scrud(Waxy Build up)
• 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 thoroughly with water before pouring.
NOTE
If you wish to use fabric softener we recommend
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 pour powdered bleach into bleach dispenser.
■ 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.
■ Softener will not be dispensed if an Option Wash is selected.
If desired, pour the recommended amount of liquid fabric softener
into the right-hand compartment.
Use only liquid fabric softener.
Dilute with water if necessary before adding 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.
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. (refer to page 21 or 33)
• 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.
