Checking the water hardness
The water hardness setting can be adjusted
on this appliance. It is important to set
the water hardness correctly, so that the
appliance indicates accurately when the
descaling programme should be run. The
factory setting for the water hardness is 4.
You can check the water hardness using the
enclosed test strip or by asking your local
water supplier.
Dip the test strip briey in water, gently
shake off any drips, and check the result
after one minute.

Tips on energy saving
► After approx. 30 minutes (factory setting),
the appliance will switch off automatically
and will not require any more energy.
► The default time can be shortened
(see Auto off after under “Displaying
settings”).
► If the appliance is not being used, switch
it off at the power switch.
► If possible, do not interrupt coffee or milk
froth dispensing. Stopping a process
prematurely results in higher energy
consumption and the drip tray lls up
more quickly.
► Always descale the appliance when
Service - descale is displayed (see
“Descaling”) to avoid a build-up of lime-
scale. Limescale residue results in higher
energy consumption.
