Water hardness

If the water hardness in your area is high or
moderate, we recommend that you use a water
softener for washing machines. In areas where
the water hardness is soft it is not necessary to
use a water softener.
To find out the water hardness in your area,
contact your local water authority.
Use the correct quantity of water softener.
Follow the instructions that you find on the
packaging of the product.
