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.

• 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
