Quantity of detergent to be used
The type and quantity of detergent will depend on the type of fabric, load size,
degree of soiling and hardness of the water used.
Follow the product manufacturers’ instructions on quantities to use.
Use less detergent if:
• you are washing a small load,
• the laundry is lightly soiled,
• large amounts of foam form during washing.
Degrees of water hardness
Water hardness is classified in so-called “degrees” of hardness. Information on
hardness of the water in your area can be obtained from the relevant water
supply company, or from your local authority.
Note: 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).
