The machine must be descaled.
Follow the step-by-step guide:
Descaler contains acids which may irritate the skin and eyes. It is essential that you observe the manufacturer’s safety warnings indicated on the descaler packet and the warnings relating to the procedure to follow in the event of contact with the skin and eyes.
Use descaler recommended by De’Longhi only. Failure to descale the appliance as described above also invalidates the guarantee.
The message "Descale Confirm?" appears on the display. Press OK again to enable the function . "Add Descaler Confirm?" appears on the display.
Pour the descaler into the tank up to the level A (equal to one 100ml packet) marked on the back of the tank. Add water (1 litre) up to level B.
L'acqua calda contenente acido viene erogata dal cappuccinatore. Evitare il contatto con gli schizzi d'acqua.
"TURN STEAM KNOB" then appears on the display .
The descaling programme starts and the descaler liquid comes out of the cappuccino maker. The descaling programme automatically performs a series of rinses and pauses to remove all the scale residues inside the coffee machine. After about 30 minutes, the message “FILL TANK!” is displayed. The appliance is now ready for rinsing through with clean water.
Empty the container used to collect the descaler solution and replace it empty under the cappuccino maker.
“Rinsing” appears on the display. Hot water comes out of the cappuccino maker. When the water tank is completely empty, “TURN STEAM KNOB” is displayed.
The coffee machine is now ready for use.
