4-6. TROUBLE SHOOTING AGAINST COMMON WASHING PROBLEMS
Many washing problems involve poor soil & stain removal, residues of lint and scum, and fabric damage. For
satisfactory washing results, follow these instructions.
WASH PROBLEM
Problems
Poor soil
removal
• Not enough Detergent
• Wash Water
Temperature too low.
• Overloading the washer
• Incorrect wash cycle
• Incorrect sorting
• Stain not pre treated.
Possible Causes
Solutions & Preventive Measures
• 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. (refer to page 10)
• Reduce load size.
• Wash with JEAN or  SOAK & JEAN wash cycle for heavy soiled
laundry.
• Separate heavily soiled items from lightly soiled ones. 
• Pretreat stain and heavy soil according to directions shown on
page 9.
Blue, Grey, or
Brown Stains
• Undiluted fabric softener
dispensed directly onto
fabric
• 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 12 for more instructions.
Black or Gray
marks on
clothes
• A buildup caused by the
interaction of fabric
softener and Detergent
can flake off and mark
clothes 
• Not enough Detergent
• Refer to the recommendations against Scrud(waxy buildup). 
(refer to scrud page12.) 
• Use correct amount of Detergent for load size, amount of soil
and water Hardness.
Yellow or
brown rust
stains
• Iron or manganese in
water supply, water
pipes, or water heater
• 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.
Lint
• Incorrect sorting 
• Tissues left in pocket 
• Overloading the washer
• Wash lint givers eg towels, flannelette sheets, separately from
lint collectors eg synthetic fabrics and remove tissues in pockets
before wash. See page 9 for sorting and caring before loading.

Result of Check
Possible Cause
How to repair & settle
Household Power supply
1. Check whether connection between the
plug and the electrical is poor
2. Measure voltage of the electrical.
Wiring of the Washer
1. Measure resistance between both ends
of the power supply cord with both the
