Useful tip: If your water hardness is
>21 °dH (3.8 mmol/l), we recommend
instead to use bottled drinking water
2+
(< 150 mg/l Ca ). This will mean your
coffee machine will need to be
descaled less often and there will be
less impact on the environment
because less descaling agent will be
used.

Proximity sensor

The proximity sensor detects when your
hand or body comes close to the touch
display. You can activate the following
functions separately:
– Switch the light on: You can decide
whether the light switches on when
the coffee machine is switched on or
off.
– Acknowledge buzzer: Buzzer tones
are suppressed, e.g. with the
replace the water container
– Switch the appliance on: The start
screen is displayed.
