Direct Water Connection
To secure in cup quality day after day, machine performance and longevity, the machine descaling concept includes
two stages:
• recommended stage
• mandatory stage
Once the descaling threshold is reached, the descaling symbol is displayed on the machine screen and indicates that
machine have entered the recommended descaling stage. The machine is not blocked. This stage lasts 15 days.
If descaling is not performed during the recommended period, the machine enters mandatory stage and becomes
blocked. The only way to unblock it is to perform a descaling.
Note: 7 days before the recommended stage starts, the descaling symbol starts blinking. The same principle applies for
both coffee module and milk module descaling.

If the machine is installed with an external water filtration system, a descaling alarm will be triggered after 1000 liters.
When a machine is connected to the direct water connection (DWC-IN), the water tank is not necessarily monitored on
a daily basis. For this reason, we have (re-)implemented a cleaning alert every 30 calendar days, displayed through a
clean symbol illustrated in blue. This alert is associated within a cleaning routine.
