If you cannot find out the water
hardness level, you can use the test
strip provided:
^ Dip the strip in your drinking water for
approximately a second, then shake
off any excess water. The result will
be evident after about a minute.
Set the water hardness according to
the table. The water hardness set is
shown by the flash frequency of the k
indicator light.

The FashionMaster is set to the highest
level of water hardness (12.6 mmol/l /

you do not need to do anything. See

If your water hardness is different from
this, you must adjust it to the
corresponding value.
Where the water hardness fluctuates
e.g. between 6.7 - 9.0 mmol/l (37 - 50
°dH), always programme it to the higher
value (9.0 mmol/l / 50 °dH in this
example).
In the event of a fault, it will help the
service technician if you know the
hardness of your local water supply.
