Detergents and Conditioners
Which detergent and conditioner?
Use only detergents and conditioners which are suitable for use in au-
tomatic washing machines. Always follow the manufacturer's instruc-
tions.
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 or an EASY IRON pro-
gramme 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.
