Many washing problems involve poor soil and stain removal, residues of lint and scum, and fabric damage. For
satisfactory washing results, follow these instructions.
Use ONLY powdered or liquid HE (High Effificiency) detergents. Do NOT use flakes scraped from a soap cake
or bar, flakes, soap ribbons (available in some markets,) detergent tablets, plastic pouches, magic laundry
balls, or anything other than powdered or liquid HE detergent products. Do not use soap of any kind. Do not
use other types of detergent or soap products, such as hand soap, dishwashng liquid, or any others.

Detergent

Holes, tears,

·Insufficient detergent
·Wash water temperature too low
·Incorrect wash cycle
·Laundry missorted
·Stains not properly pretreated

·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
·Tissues left in pocket
·Overloading the washer

·Overloading the washer
·Undissolved detergent
·Excessive detergent

·Incorrect use of chlorine bleach.
·Unfastened zippers, hooks,

buckles

·Ribs, tears and broken threads
·Overloading the washer
·Degradation of fabric

·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 heavy or soak & heavy 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 15.

·Pretreat the stain with detergent or a stain removal agent.
·Do not overfill fabric softener dispenser and do not pour liquid fabric

softener directly onto fabric.
See page 13 for more instructions.

·Keep the recommendations against scum (waxy buildup).
·Use correct amount of detergent for load size, soil level, 

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-producing items, like flannel sheets, towels, and the like

separately from dark fabrics and fabrics that tend to collect lint.
Remove all items, including tissues and papers, from the pockets of
items to be washed. See page 9 for sorting information. 

·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 11 for adding liquid bleach.

·Fasten zippers, hooks, and buckles.
·Remove objects in pockets. See page 9 for caring before loading.
·Do not overload the washer.
