Tip: If your water hardness is
>21.8gpg (21°dH), we recommend
using bottled drinking water instead
(<150mg/lCa
2+
). 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.
System lock
You can lock the coffee machine to
prevent it from being used by
unauthorized persons, such as children.
