Descaler
De’Longhi descaler
Container
Recommended capacity: 2 l
Time
~45min
Important:
If the water softener filter is installed, it must be re-
moved before adding the descaler solution.
Put the filter back in the machine after the first tank of
rinsing has been completed.
The descaling procedure is described in the Quick Guide.
Please note:
• Once the descaling cycle has begun, it cannot be inter-
rupted and must be completed with the entire rinse cycle.
• After descaling, it is normal for the grounds container to
contain water.
• If the water tank has not been filled to the MAX level after
descaling, the appliance prompts for a third rinse to en-
sure that the descaler solution has been completely elimi-
nated from the machine’s internal circuits. Before starting
rinsing, remember to empty the drip tray.
