Many washing problems involve poor soil & stain removal, residues of lint and scum, and fabric damage. For satisfactory washing
results, follow these instructions.

Poor soil
removal

Blue Stains

Black or gray
marks on
clothes

Yellow or
brown rust
stains

Lint

Residue or
Detergent

Holes, tears,
or snags

Undiluted fabric softener
dispensed directly onto fabric

A buildup caused by the interaction
of fabric softener and Detergent
can flake off and mark clothes
Not enough Detergent

Iron or manganese in water
supply, water pipes, or water
heater

Incorrect sorting
Incorrect sorting
Overloading the washer

Overloading the washer
Undissolved Detergent
Use too much Dtergent

Incorrect use of chlorine bleach.
Unfastened zippers, hooks,
buckles 
Ribs, tears and broken threads
Overloading the washer
Degradation of fabric

Not enough Detergent
Wash Water Temperaturetoo low.
Overloading the washer
Incorrect wash cycle
Incorrect sorting
Do not pretreat stain.

Use correct amount of Detergent for load size, amount of soil and
water Hardness.
Use WARM or HOT water for normal soil. Different Water Temperature
may be required according to soil type. 
Reduce load size.
Wash with Heavy or Soak & Hand Wash for heavy soiled laundry.
Separate heavily soiled items from lightly soiled ones.
Pretreat stain and heavy soil according to directions shown on
page 11.

Rub the stain with bar soap Wash.
Do not overfill fabric softener dispenser and do not pour liquid fabric
softener directly onto fabric. 
See page 14 for more instructions.

Keep the recommendations against Scrud (waxy buildup).
Use correct amount of Detergent for load size, amount of soil
and water Hardness.

To restore discolored load of whites, use rust remover safe for
fabric.
Install nonprecipitating water softener or an iron filter in your
water supply system for an ongoing problem.
Before washing, run water for a few minutes to clear lines.

Wash lint givers eg towels, flannelette sheets, separately from
lint collectors e.g. synthetic fabrics and remove tissues in
pockets before wash. See page 11 for sorting and caring before
loading.
Do not overload the washer

Do not overload the washer.
Some Detergents need to be pre-dissolved, check the
Detergent instructions. Try pre-dissolving the Detergent.
Increase Water Temperature using HOT water safe for fabric.
Use proper amount of Detergent.

Never pour chlorine bleach directly on fabric.
See page 13 for adding liquid bleach.
Fasten zippers, hooks, and buckles.
Remove objects in pockets. See page 11 for caring before loading.
Do not overload the washer.

For more detailed information for trouble shooting refer to page 44 to 53.

Where, what & how to check?

Result of Check

Possible Cause

How to repair & settle

1. Check whether connection between the

plug and the electrical is poor

2. Measure voltage of the electrical.

1. Measure resistance between both ends

of the power supply cord with both the
plug pins short-circuited.

2. Check whether every connector in the

bundle of connectors has a good
connection.

3. Check resistance of every wire to find

out a open wire.

1. Check resistance with power relay

switch turned on

2. Check the secondary voltage of the

transfomer.

3. Measure resistance to check whether

the T.P of the motor is blown out.

4. Check whether the fuse is open.

If there are no defects in the above,
it should be defect of the controller.

If supply voltage is 120% higher than
rating the varistar in the controller may
be broken. Check supply voltage.
