USING THE APPLIANCE FOR THE FIRST TIME

Coffee has been used to factory test the appliance and it is therefore completely normal for there to be traces of coffee in the mill.

Connect the appliance to the mains supply. Press the ON/ stand-by button (A7). Set the required language.
Set the language using the icons (B7 and B8).
After 5 seconds, the appliance displays “FILL TANK”. Extract the water tank (fig. 4), rinse and fill with fresh water without exceeding the MAX line.
Place a cup under the cappuccino maker (fig. 5). Press the OK icon (B9) and after a few seconds a little water comes out of the spout.
The machine now displays “TURNING OFF... PLEASE WAIT” and goes off.
Extract the appliance by pulling it out using the handles (fig. 6). Open the lid and fill the container with coffee beans, then close the lid and push the appliance in.

Important! Never introduce pre-ground coffee, freeze dried coffee, caramelised beans or anything else which could damage the appliance.

Note: When using the appliance for the first time, you need to make 4-5 cups of coffee and 4-5 cappuccinos before the appliance gives satisfactory results.

TURNING ON AND HEATING UP

Each time the appliance is turned on, it performs an automatic preheat and rinse cycle which cannot be interrupted. The appliance is ready for use only after completion of this cycle.

Danger of burns! During rinsing, a little hot water flows from the coffee spouts.

To turn the appliance on, press the ON/OFF/stand-by button (A7) (fig. 1). The message “HEATING UP... PLEASE WAIT” is displayed.
When heating is complete, the message changes to “RINSING”.
The appliance is at temperature when the message “MEDIUM CUP NORMAL TASTE” is displayed.

MAKING COFFEE USING COFFEE BEANS

The appliance is preset to make coffee with a normal taste. You can also choose coffee with an extra-mild, mild, strong or extra-strong taste. There is also a pre-ground coffee option. To choose the required taste, press the icon (B4) (fig. 7) a number of times. The required coffee taste is displayed.
Place 1 cup under the spouts to make 1 coffee (fig. 9) or 2 cups for 2 coffees (fig. 8). Lower the spouts as near as possible to the cup for a creamier coffee (fig. 10).
Press the icon (B5) (fig. 11) to select the type of coffee: espresso, small cup, medium cup, large cup, mug.
Now press the icon (B10) (fig. 12) if you want to make a coffee and the icon (B11) (fig. 13) if you want to make 2 coffees.
The appliance now grinds the beans and starts delivering the coffee into the cup.

To turn the appliance off, press the ON/OFF/stand-by button (A7) (fig. 1).

Troubleshooting and error codes

DISPLAYED MESSAGE	POSSIBLE CAUSE	REMEDY
FILL TANK!	The water tank is empty or positioned incorrectly.	Fill the tank with water and/or insert it correctly, pushing it as far as it will go.
GROUND TOO FINE ADJUST MILL AND (alternating with) PRESS OK	The grinding is too fine and the coffee is delivered too slowly.	Turn the grinding adjustment knob one click clockwise towards "7".
GROUND TOO FINE ADJUST MILL AND (alternating with) PRESS OK (then) FILL TANK!	The machine cannot make coffee as there is air in the hydraulic circuit Possible cause: the filter has not been installed correctly.	Make sure the filter (A26) is properly installed and that the installation has been carried out correctly.
EMPTY WASTE COFFEE CONTAINER	The waste coffee container (A4) is too full or more than 3 days have passed since you last made coffee (this guarantees correct hygiene of the machine).	Empty the waste coffee container and clean, then replace. Important: when removing the drip tray, the waste coffee container MUST be emptied, even if it is not completely full. If this is not done, when you make the next coffees, the waste coffee container may fill up more than expected and clog the machine.
INSERT WASTE COFFEE CONTAINER	After cleaning, the waste coffee container has not been replaced.	Open the service door and insert the waste coffee container.
ADD PRE-GROUND COFFEE	The "pre-ground coffee" function has been selected without placing any pre-ground coffee in the funnel. The funnel (A21) is blocked.	Extract the appliance and place pre-ground coffee in the funnel. Empty the funnel with the help of a knife as described in the section “Cleaning the pre-ground coffee funnel".
PLEASE DESCALE!	The machine must be descaled.	The descaling procedure described in the “Descaling" section needs to be performed as soon as possible.
LESS COFFEE	Too much coffee has been used.	Select a milder taste or reduce the quantity of pre-ground coffee, then make the coffee again.
FILL BEAN CONTAINER	The coffee beans have run out.	Fill bean container
INSERT BREWING UNIT	The brewing unit has not been replaced after cleaning.	Insert the brewing unit as described in the section "Cleaning the brewing unit".

PROBLEM	POSSIBLE CAUSE	REMEDY
The coffee is not hot	The cups were not preheated.	Warm the cups by rinsing them with hot water.
	The brewing unit has cooled down because 2/3 minutes have elapsed since the last coffee was made.	Before making coffee, preheat the brewing unit by selecting the RINSING function in the menu.
	The temperature set is too low.	Change the set temperature (see paragraph “Changing coffee temperature").
The coffee is not creamy enough	The coffee is ground too coarsely.	Turn the grinding adjustment knob one click anticlockwise towards "1" while the coffee mill is in operation (fig. 11).
	Wrong type of coffee	Use a type of coffee for espresso coffee makers.
The coffee is delivered too slowly or a drop at a time.	The coffee is ground too finely.	Turn the grinding adjustment knob one click clockwise towards “7” while the coffee mill is in operation (fig. 11). Continue one click at a time until coffee delivery is satisfactory. The effect is only visible after delivering two coffees.
The coffee is delivered too quickly.	The coffee is ground too coarsely.	Turn the grinding adjustment knob one click anticlockwise towards "1" while the coffee mill is in operation (fig. 11). Avoid turning the grinding adjustment knob excessively otherwise when you select 2 cups, the coffee may be delivered a drop at a time. The effect is only visible after delivering two coffees.
Coffee does not come out of one of the spouts.	The spouts are blocked.	Clean the spouts with a toothpick (fig. 23).
