Tip: If your water hardness is >21 °dH
(3.7 mmol/l), we recommend using
bottled drinking water instead
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.

you approach the touch display with
your hand or body. You can activate the
