Documentation required
The following technical documentation is required for repairs:
Instruction booklet of specific model
Technical documentation of specific model
Equipment
As well as the standard equipment, the following tools are required:
1 Special screwdriver with Torx T10 tip
1 Digital thermometer with scale of > 150°C
Must be suitable for measuring in liquids and on surfaces
Safety warnings
Before starting operations on the appliance, consult the relative instruction booklet.
Observe all current standards related to repairs of domestic appliances.
Always disconnect the power plug from the mains before carrying out repairs. Simply turning off
the main switch is not sufficient to prevent electrical shock.
The SIRIUS models are class 1 appliances. On completion of repairs the insulation and dielectric
withstand tests must be performed.

To enter test mode, press the following buttons
Press buttons 1 and 3 and switch on the appliance by means of the
main switch at the rear or button 6 (menu)
The software version is shown on the display.
Leave the buttons previously pressed.
Gearmotor counterclockwise rotation
Button 1
Ensure correct counterclockwise rotation of the gearmotor and
correct ascent of the coffee unit.
Check the noise level of the gearmotor.
When the gearmotor has reached the delivery position, the display
shows the number 1 on the top line.
Gearmotor clockwise rotation
Button 2
Ensure correct clockwise rotation of the gearmotor and correct
descent of the coffee unit.
Check the noise level of the gearmotor.
When the gearmotor has reached the rest position, the display
shows the number 2 on the top line.
Coffee grinder operation
Button 3
Ensure correct counterclockwise rotation of the coffee grinder
Check the noise level of the coffee grinder, keeping it pressed until it
stops automatically (the display shows the letter “M”)
If the grinder motor is running, the lower line to the right of the
display shows the number of revolutions per second of the coffee
grinder (around 6-12) while the letter A flashes on the top line.

Operating logic with “AQUA PRIMA” filter”
When the “aqua prima” filter is selected on the user menu or via the control panel, the system
water count logic is as function:
If the “aqua prima” function is enabled, the electronics performs a pulse count of the turbine,
recording one pulse every 2 revolutions.
If the “aqua prima” function is disabled, the electronics performs a pulse count of the turbine,
recording one pulse every revolution.

Ground coffee dose adjustment (aroma)
The dose of ground coffee, and therefore the aroma, can be adjusted via the appliance display.
There are two settings:
1. DEFAULT (user menu)
2. INSTANT
DEFAULT setting
On selection of the setting, the appliance remains in this mode, even if switched off or in the
event of a power failure.
To adjust proceed as follows:
INSTANT setting
The setting can be made before delivery of coffee.
As soon as the required coffee is produced (stronger or milder) the appliance automatically
returns to DEFAULT (see above).
To set the INSTANT mode, proceed as follows:
56
For reasons of clarity, the table below states the grams of coffee corresponding to the number of
coffee grinder pulses:

Theaverage grinding time is 1.3-1.5 g/sec.
Factory settings are 100 pulses, equal to a dose of approx. 8.5 g. (Factory setting)
* The dose varies according to the coffee blend used and relative humidity.
57
SBS valve
To ensure correct operation of the valve SBS a long espresso coffee should be made, and during
preparation of the latter, check the difference in speed of delivery between the maximum and minimum
positions.
The difference in delivery speed is approx. 2.5 times greater (and therefore VERY obvious!!).
An excessively fine grinding influences operation of the valve SBS.
Troubleshooting
Fault
The coffee is delivered
slowly with SBS in the
maximum position (pos.1)
The coffee is not delivered
with SBS in the minimum
position (pos.2)
- The text
“fill circuit ” appears on
display (Digital model)
- The red water low
indicator light is flashing
Probable causes
Grinding too fine
Remedies
Set to a coarser grinding level.
Grinding too fine
Set to a coarser grinding level
The water circuit is empty

New valve on upper sleeve for wand
To avoid pressure overload caused by clogging of the upper sleeve for the wand (this often occurs
when the wand is not cleaned thoroughly after preparing a cappuccino), the sleeve is fitted with a
limiter valve that opens when the pressure exceeds a value of around 2 bar.
The figure below shows the sleeve during normal operation (closed) and when there is a pressure
overload inside (open).

The AQUA PRIMA filter
The models Incanto s-class (Sirius and Rondò) are equipped with a softener filter that significantly
reduces water hardness, thus minimising possible problems caused by lime scale.
In fact, to obtain a perfect coffee, the water is an essential element, on a par with the blend and
roast of the coffee: it must always therefore be clear and fresh.
The filter operating modes and features are described below.
The water to prepare the coffee is filtered
just before delivery.
This guarantees constant optimal water for
a perfect coffee.
There are four phases the Aqua Prima Filter purifies the water, to achieve a unique coffee.
1. The active carbons eliminate unpleasant odours or substances from the water, such as chlorine.
The silver coating of the active carbon obstructs the reproduction of germs.
2. The ion exchanger reduces the lime scale deposit and eliminates heavy metals and suspended
substances from tap water.
3. A special porous filter retains undesired micro particles.
4. T
he corpuscular filter, used as a connection between the tank and appliance, filters the water,
retaining any suspended substances or impurities.
60
As can be noted in the graph below, the “aqua prima” filter reduces water hardness by up to 50 %

The aqua prima filter filters up to 60 litres of water or around 600
coffee cups.
It should be replaced every 3 months.
On the Incanto s-class models, the need to replace the filter is
indicated by a lamp or message on display.
If the machine is not equipped with these control devices, .
observe the expiration date printed on the filter packaging
All parts comprising the aqua
prima filter system have
been tested for contact with
food.
The aqua prima filter
respects the environment
and is 100% recyclable.
The aqua prima filter pack
complies with recycling
standards specified by the
“green dot”.
