The amount of detergent used
depends on the level of soiling:
Light soiling
No soiling or stains are visible.
Normal soiling
Some visible soiling or a few light
stains.
Heavy soiling
Very visible soiling or stains.
The size of the load and the water
hardness level in your area have an
impact on the amount of detergent
necessary to obtain optimum wash
results. If you do not know the water
hardness level in your area, contact
your local water authority.

Water softener
If the water hardness level is between II
and III, you can soften the water to
reduce detergent consumption.
The detergent packaging should
indicate the correct amount to use in
your machine. Add the detergent, then
add the water softener. You can then
use the recommended amount of
detergent for water hardness level I.
