Operating Instructions

Water softener

For medium to high water hardness (hardness class II upwards), you
should use softener. Refer to the manufacturer's instructions. Then
always add the appropriate amount of detergent for hardness class I
(= soft). The responisable water works will provide information on the
local water hardness.
Since the water softener is rinsed in before the main detergent (water
2
pre-softening), 80% of the stated quantity of softener shown on the
package is sufficient.
