9.3. Water tank removal

Every time the water tank is removed and re-inserted again, air bubbles can be pushed in the fluidic line, thus potentially impacting the performance of the pump
and consequently impacting the overall machine performance or the in-cup volume stability. To correct it, an automatic process is implemented once the water
tank is reinserted in the machine.
The machine performs a short priming of the fluid line directly in the drip tray (< 20 ml). This will flush away any air bubbles that would be trapped in the fluid
line. The process is not visible by the user and last few seconds: no message is shown on display, no user interactions are blocked.

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.

water tank needs to be cleaned
The milk system requires a mandatory yearly maintenance (please refer to the service package associated with the
machines). Similarly to the descaling concept, the yearly maintenance threshold follows both recommended and man-
datory stages:
• The recommended stage last 60 days (the maintenance required symbol is indicated on the machine screen)
• After the 60 days, if the yearly maintenance is not performed, the machine enters the mandatory stage.
Note: 10 days before the mandatory stage starts, the maintenance required symbol blinks.
Important note: when the mandatory phase is reached, the machine does not block. Beverages are always
