Water hardness
The appliance is factory preset for
a medium water hardness index (3).
This mode allows you to set the water
hardness value in order to optimise the
descaling process.
1. Turn the control knob right or left to set the
correct water hardness.
2. Press the control knob to confirm.
If your mains water supply is too
hard, we recommend
using a water softener.
Request information on the
hardness of your water from your
local water board.
