Read all instructions before using your washer
Save these instructions
Your safety is important to us.
To reduce the risk of fire, electrical shock, or injury when using your washer adhere to
the following basic precautions.
Understanding your responsibilities
•Flammable fluids (dry-cleaning solvents,
kerosene, gasoline, etc.) should not be
used or stored in or near your washer.
Do not add flammable fluids to your wash
water. These substances give off vapours
that can create a fire hazard or explosion.
•Have only a qualified person install, repair,
or replace parts on your washer.
•Maintain your washer properly.
•Protect your washer from the weather and
keep it where the temperature will not fall
below freezing.
•Do not install the washer at a place of
extremely high humidity. It could cause an
electric shock or a short circuit.
•Ground your washer properly.
• Connect your washer to the correct outlet,
electrical supply, water supply, and drain supply.
•Do not wash fiberglass materials.
Small particles can stick to fabrics washed in following loads and cause skin irritation.
•After starting a cycle, do not reach into the
spin basket until all motion stops.
•Do not tamper with the controls.
•The appliance is not intended for use by
young children or infirm persons without
supervision.
•Do not use chlorine bleach and ammonia or acid (such as vinegar or rust remover) in the
same wash. Hazardous fumes can form.
•
Young children should be supervised to ensure
that they do not play with the appliance.
•If the supply cord is damaged, it must be
replaced by the manufacturer or its service
agent or a similarly qualified person in order
to avoid a hazard.
•Do not spray water on the control panel and back cover of the washer.
It could cause fire or an electric shock.
• In the case of the dual valve model, if you only connect the cold water inlet valve, if the water temperature
is selected as hot or warm, there may be water leakage from the unconnected water inlet valve.
•Unplug power supply cord before attempting to service your washer.
• If the appliance is supplied from an extension cord
set or electrical portable outlet device it should be
positioned so it is not subjected to splashing or
moisture.
Please ...
WASHER SAFETY
•Do not use hot water if standard temperature is over 50ßC (122ßF).
It could cause a deformation of plastic parts.

Preparing clothes for washing
To obtain the best washing results, you must operate your washer properly.
This section gives you this important information.
OPERATING YOUR WASHER
•Close zippers, snaps, and hooks to avoid
snagging other items.
Remove pins, buckles, and other hard
objects to avoid scratching the washer
interior.
•Empty pockets and turn them inside out.
•Turn down cuffs and turn synthetic knits
out to avoid pilling.
•Tie strings and sashes so they will not
tangle.
•Treat spots and stains.
(see "Removing stains" on page14)
•Drop items into washer loosely. Items
should move easily through wash water
for best cleaning and wrinkle-free results.
•Load washer properly and select correct
load size setting.
Overloading and selecting a setting too
small for the wash load can:
- cause poor cleaning
- increase wrinkling
- create excessive lint
- wear out items faster (because of pilling)
•Mix large and small items in each load.
Load evenly to maintain washer balance.
An unbalanced load can make the washer
vibrate during spin.
•Reduce wash time when using a small
load size setting. Loads with only a few
small items need less wash time.
•Use a large load size setting to reduce
wrinkling with permanent press clothes
and some synthetic knits. These items
should have more room to move in the
water than heavy items (towels, jeans).
•Separate heavily soiled items from lightly soiled ones, even if they would normally be
washed together.
•Separate dark colours from light colours, colourfast items from non-colourfast item.

CARING FOR YOUR WASHER
Proper care of your washer can extend its life. This section explains how to care for
your washer properly and safely.
Cleaning your washer
Winter storage or moving care
Install and store your washer where it will not freeze. Because some water may stay in the
hoses, freezing can damage your washer.
If storing or moving your washer during freezing weather, freeze proof it.
Non-use or holiday care
Operate your washer only when you are at home.
If you will be on holiday or not using your washer for an extended period of time, you should;
•Unplug the power supply cord or turn off eletrical power to the washer.
•Turn off the water supply to the washer .
This helps avoid accidental flooding (due to a water pressure surge) while you are away.
Wipe up detergent, bleach, and other spills
with a soft, damp cloth or sponge as they
occur. Occasionally wipe the outside of the
washer to keep it looking like new.
Clean interior with 250ml of chlorine bleach
mixed with 500ml of detergent.
Run washer through a complete cycle.
Repeat process if necessary.
•Turn off water tap.
•Disconnect and drain water inlet hoses.
•Run washer on a drain and spin setting
(see page 10) for 1 minute.
•Unplug the power supply cord.
•Flush water pipes and hoses.
•Reconnect water inlet hoses.
•Turn on water faucet.
•Reconnect power supply cord.
Do not put sharp or metal objects in your
washer, they can damage the finish. Check all pockets for
pins, clips, coins, bolts, nuts, etc..
Do not lay these objects on your washer after emptying
pockets.

HOW TO CLEAN THE FILTER
Cleaning the Lint Filter
Cleaning the drain filter
•In the case of a "Pump-Model" drain hose, this filter is situated at the back side of the washer.
•This drain filter is to screen foreign stuffs such as threads, coins, pins, buttons etc ..
•If the drain filter is not cleaned regularly (once every three month), drain problem could
be caused.

Stained, heavily-soiled, or greasy items may need to be prewashed or soaked for best results.
Soaking helps remove protein-type stains like blood, milk, or grass. Prewashing helps loosen
soil before washing.
Stain removal rules
•Use warm water for soaking or prewashing stained laundry. Hot water can set stains.
•Most stains are easier to remove when they are fresh.
•Before treating any stain, find out what kind of stain it is, how old the stain is, what kind of
fabric it is, and if the fabric is colourfast. (Check the care label)
•Washing and drying can set some stains.
•Start with cold or warm water. Hot water can set some stains.
•When bleach is recommended, use a bleach that is safe for the fabric.
•Put the stained area face down on a paper towel or white cloth. Apply the stain remover
to the back of the stain. This forces the stain off fabric instead of through it.
