Detergent and Conditioners
Which detergent and conditioner?
Use only detergents and conditioners which are suitable for use in
automatic washing machines. Always follow the manufacturer's
instructions.
How much detergent and conditioner?
The required quantity depends upon:
•the extent of soiling of the washing
•the hardness class of the mains water
•the amount of washing
2 Should the detergent manufacturer not specify the dosage quantity for
less than full loads, reduce the detergent accordingly:
for a half load reduce the quantity by 1/3.
for a small load reduce the quantity by 1/2.
Observe the instructions for use and dosing provided by the detergent
and conditioner manufacturer.
Water Softening
For medium to high water hardness (hardness class II upwards) a water-
softening agent can be used. Refer to the manufacturer's instructions.
Then always add the appropriate amount of detergent (underdosing)
for hardness class I (soft). Your local Water Authority can advise you on
the hardness of the water in your area.
