Detergents and additives
Which detergent and additive?
Use only detergents and additives for washing machines. Follow the
manufacturer’s instructions.
How much detergent?
The quantity depends on:
• the load:
if the manufacturer does not provide any indications on the amount of
detergent for small loads, use about one third less than the suggested
amount for half loads and half the amount for very small loads;
• the degree of soil:
use a small amount of detergent for lightly soiled garments. Judge
the amount according to the detergent manufacturer’s instructions
and size of the load;
• the water hardness:
the harder the water, the more detergent required. Instructions
according to water hardness are given on the detergent pack.
Liquid detergent
Liquid detergent can be poured directly into the main wash compartment
of the dispenser drawer
immediately
before starting the programme, or
a special dispenser can be used that is placed directly in the drum. Mea-
sure the detergent according to the manufacturer’s instructions.
Adding a water softener (descaling product)
A water softener must be added when water has a medium-high degree
of hardness (from degree of hardness II). Follow the manufacturer’s
instructions. The quantity of detergent can then always be adjusted to
degree of hardness I (= soft). Information on water hardness can be
obtained from your local water supply authority.
