Cleaning and maintenance operationsGeneral cleaning

To ensure a good coffee quality and a longer working life, always keep the machine clean.

Before cleaning the machine, turn off the main switch, unplug the machine and wait until it cools down.

Do not immerse the machine into water or other fluids: it may be irreparably damaged!

Do not wash parts of the machine in the dishwasher!

Always handdry all parts of the machine, do not dry them in the oven or microwave oven!

Water tank, drip tray, coffee grounds container and coffee dispenser

39

In order to keep the service area and the central unit (22) clean, daily empty the coffee grounds container (1), after machine use.

The water tank (11), drip tray (2), cup holder grill

(3)and coffee grounds container (1) should be washed periodically, using a non-abrasive solvent and drying them carefully.

40

Coffee dispenser (4) may be removed for cleaning

operations. Unloose the screws and rinse the dispensing tube thoroughly with hot water.

From time to time, clean the machine casing with a damp cloth and dry it.

Clean pre-ground coffee container (14) with the aid of the brush supplied, whenever necessary.

Central unit

Clean central unit (22) whenever the coffee bean container is filled, or at least once a week.

Switch off the machine and open service door (19). Remove grounds coffee container (1).

41

Remove central unit (22), by holding the handle and shortly pressing the PRESS key.

Wash the central unit with hot water; do not use any solvent.

42

Make sure there are no coffee residues on the two steel filters: the upper filter can be removed by unloosening and turning the plastic pin anticlockwise using the tool supplied.

Dry thoroughly each central unit component, fit the filter again and tighten it properly with the screw .

43

Remove coffee rest drawer (23) and clean it, using a non-abrasive solvent.Clean the service area thoroughly and fit the coffee rest drawer again.

44

By holding the central unit by its handle, slide it back into its original position, making sure it is correctly engaged. Then close the door. Fit the coffee grounds container again.

When fitting the central unit, do not press “PRESS” button: it may cause
irreparable damages to the machine!

Warning: if the central unit is not correctly fitted, the following message will be displayed:

"BREW UNIT MISS "

The machine cannot dispense coffee.Coffee grinder

Never fill the coffee grinder with water: it may irreparably damage the machine!

45

Clean the coffee beans container periodically; this operation should be accomplished by a qualified technician! Unplug the machine.

Empty the coffee container and unloose the two fastening screws. Now, the container can be removed and cleaned.

46

Carefully pull the adjustment lever upwards, previously writing the set grinding degree.

47

Turn the adjustment ring counterclockwise, until the blue marks coincide.

48

Now, it is possible to remove the grinding ring from the machine, slightly pulling it upwards.

49

With the aid of a brush or a narrow vacuum hose, clean both the gear box and the grind ring support.

Make sure the position of the grind ring does not shift.

To reassemble the coffee grinder, carry out the reverse sequence, making sure the adjustment ring has not been shifted during cleaning. If that is the case, turn it until the blue mark coincide with one of the three notches.

Assemble the grind ring support and make sure the blue marks coincide.

50

Turn the adjustment ring clockwise, to make the red marks coincide.

51

Fit the adjustment lever on the ring, until it coincides with the previously set grinding degree.

Cappuccinatore 52

To quickly clean the cappuccinatore, immerse the suction pipe into warm water and let water flow through it.

For a more accurate cleaning, remove the cappuccinatore and open cover (29). Clean the outside part with warm water and rinse it with cleaned water.

Descaling

Attention:Thedescalingoperationsmus be carried out when the machine components are cold.

Descaling removes limescale from all surfaces and holes, thus ensuring a perfect operation of valves, heating controls and other important parts.

Note: due to the complexity of the coffee machine hydraulic circuit, the following descaling cycles (automatic and standard) do not allow the descaling of all tubes.

In fact, easily accessible components such as the central unit (22) and its plastic connection are excluded.

The machine must be descaled every 3-4 months, depending on the water hardness degree.

A more frequent descaling is recommended wherever the water hardness degree is very high. To avoid dangerous delays to users, this machine is supplied with a special control counter, reminding the user to perform this operation, according to the water hardness degree.
