Possible cause and solution
Liquid detergents do not usually contain bleaching
agents. They do not remove fruit, coffee, and tea
stains.
 Use powder detergent containing a bleaching
agent.
 Pour stain removers into the  drawer in the
dispenser compartment and liquid detergent into a
dispenser ball.
 Never put stain removers and liquid detergent
together in the detergent drawer.
The detergent contained compounds (zeolites) to aid
water softening which are not soluble in water. These
have ended up on the laundry.
 Try and brush off the residues with a soft brush
once the laundry is dry.
 In the future, wash dark textiles using a detergent
which contains no zeolites. Liquid detergents do
not usually contain zeolites.
 Select a program with prewash. Use liquid
detergent for the prewash.
 Continue to use universal powder detergent for the
main wash.
The use of heavy-duty detergent is recommended in
the main wash for very heavily soiled work clothing.
Please seek advice from the detergent and cleaning
agent manufacturer.
Insufficient amounts of detergent were used. The
laundry was heavily soiled with grease (oils,
ointments).
 Use more detergent or liquid detergent with this
type of soiled laundry.
 Before washing the next load, run a 60°C (140°F)
program with liquid detergent and no load.
