2.1. Specication for the measurement of the coee products temperature.
e below procedure is also contained in the Symptom Cure 97832.
e temperature is inuenced by the ow from the dispenser and stratication of temperatures in
the glass. In order to consider these phenomena and to introduce measures that allow comparisons
in controlled conditions, below guidelines must be followed:
Conditions:
a) Water temperature in tank: 23°C (+/-2°C).
b) It must be used a plastic cup (see picture N°1).
c) It must be used a thermocouple thermometer (e.g. type K - see picture N°2).
d) e coee machine is tested without any change of parameters or calibrations, which may aect the
temperature of products, so the measurement of temperature must be done with machine in default factory
setting.
Procedure:
1. e temperature must be measured in the cup, immediately aer dispensing. Cup has to be placed on a non-
metal surface using a thermocouple thermometer (Picture 1).
2. e temperature in the cup is measured by immersing the probe of the thermometer up to touch the bot
tom.e probe then must be moved in a circular motion for 5/6 rotations. At the of the rota- tions, stop in the
center of the cup (Picture 2).
3. e highest temperature measured during the rotations is the value we are searching for, and that must be
reported;
4. Test measurement: from end of dispensing to the end of rotations must be completed within 12 seconds.
5. e distance of the probe from the bottom of the glass is a function of the quantity of coee dis- pensed:
10mm for 35gr - 17mm for 60gr - 35mm for 120gr and superior (Picture 3).
Limits of acceptability
e acceptance limits are divided by features and
products and are the following:
Espresso Q.ty 40 ml.
Temperature of 1st product 72°C ≤ 80°C
Temperature of 2nd product 75°C ≤ 85°C

2.2. Specication for the measurement of the Milk products temperature.
Milk evaluation
To carry out the test, a partially skimmed UHT milk with a percentage of grease between 1.5-1.8% at a refrige-
rator temperature Trefr. (between 4 to 10°C) must be used.
e milk product must be checked on a beaker of 250 ml of capability and with an inner diameter of 70mm,
brewing 100gr of product.
Parameters to be respected:
e parameters to be respected are: milk temperature and height of the cream. Each of these parameters, ho-
wever, must be evaluated depending on the type of system used for the production of hot milk. Actually
three types of devices are present on the appliances:
• Manual system (pannarello)
• Semi-Automatic system (cappuccinatore)
• Automatic system (carafe, Pinless wonder system)
Milk temperature in the beaker:
System with Pinless Wonder: With milk at Trefr. (about 4-10 °C): ≥ 45
how does it work:
1. The milk is heated in the rst chamber of the carafe thanks to the steam.
2. Then, it is mixed with air and frothed in the middle chamber.
3. Finally, in the outlet chamber, the ‘typhoon eect’ perfects the milk texture by removing
the large bubbles
Height of the milk cream in the beaker:
Manual system (pannarello) ≥ 15mm on 100gr. of brewed product
Semi-automatic system (cappuccinatore) ≥ 20mm on 100gr. of brewed product
Automatic system: carafe, Pinless wonder system ≥ 20mm on 100gr. of brewed product
How to measure the temperature of the milk.
1. e measurement is carried out in the beaker, immediately aer the end of milk brew, positioned on a non-
metallic surface, using a thermocouple thermometer (eg. Type K). Stop the preparation of mixed product:
at the end of milk brewing, where “One Touch product” function is present.
2. e temperature is measured by immersing the probe of the thermometer, positioning the probe inside
the beaker at about 10mm from the bottom of the container, then the probe moves in a circular motion for
3-5 turns, stopping at the end, at the center of the beaker. It detects the maximum temperature reached in
a time of relief between 3 to 5 seconds. e measurement has to be taken at 10mm from the bottom of the
beaker. Stir the milk before measuring to keep a constant temperature.

How to measure the milk cream.
e temperature (Trefr or Tamb) of the milk doesn’t aect as much the test result on measuring the milk cream;
by convection is assumed to always use milk at refrigerator temperature Trefr..
Manual systems (Pannarello)
Pour 100cc. of milk at Trefr. in a beaker of 250 ml of capacity and with a inner diameter of 70 mm; with ma-
chine in steam mode:
1. Open the steam knob to discharger water circuit for 4 sec, then close the knob.
2. Place the beaker with the frother dipped in milk, open the steam knob to maximum and
start the chronometer.
3. Aer about 30 to 60 seconds, close the knob and check the result on milk.
Semi-automatic systems (cappuccinatore)
Pours milk at Trefr. in a container ; with the machine in steam mode:
1. Open the steam knob to discharge water circuit for 4 sec. then close the knob.
2. Insert the silicone tube in the milk container, placing a beaker of 250 ml capacity and with an inner
diameter of 70 mm under the cappuccino maker and open the steam knob.
3. Aer having provided 100gr. of product, close the knob and check the result obtained on milk.
Note: e same applies to machines which have a steam key on the user interface and a solenoid valve in
place of the steam tap.
Automatic: Carafe, Pinless Wonder System
Aer setting the machine to brew of 100gr. of product:
1. Launch the “hot milk” function.
2. Collect the product in a beaker with a 250ml of capacity and with an inner diameter of 70 mm, and verify
the result obtained on milk. Carry out the test using milk at a Trefr..
In case the machine allows modify of the emulsion through the menu, use the machine with the default value.
Related to the above testing procedure derives the following table of acceptability:
Manual, Semi-Automatic and Automatic’s Milk System
Grams of Product Minimun Height of the milk cream
≥ 130 ≥ 30mm
120 ≥ 25mm
110 ≥ 22mm
100 ≥ 20mm

Switching on
When the machine is switched on, the gear motor repositions itself as follows:
- It acts on microswitch 1
- e gear motor changes its rotation direction and moves upwards again by approx. 1-2 mm.
- e boiler starts heating to heat the water for approx. 45 sec, in order to reach the optimal temperature.
A thermistor, NTC type (Negative temperature coecient), is used as a temperature sensor; in the event of
overheating this reduces boiler element power consumption. e electronic system detects the current boiler
temperature from the drop in voltage of the sensor and adjusts it accordingly. Heating element values and
corresponding temperatures: see table Temperature sensor (adjustment)

e gear motor is powered by a direct current motor that engages with the smaller double toothed wheel us-
ing a worm screw. e unit is mounted on the axle of the large gear wheel and when a coee is requested, it
moves from the standby position to the dispensing position, and then back to the standby position again.
e microswitch indicates to the gear motor when the brew group is in the work position or home position.

When the coee grinder is working, the soware monitors the current consumption. If the current value is
very low, the machine concludes that coee is missing; if the current value is very high, the machine concludes
that the coee grinder is blocked; instead, if the current value is in the middle, the machine concludes that all
is ok and it goes on to do the product.
Because the current consumption of grinder changes depending on the situations (motor new or old, cold or
hot, etc., coee blends), these current thresholds are not static, but dynamic.
1) When the system get the stability (i.e. the system got the current target) the coee doses should be:
A1 A2/3 A4/5
7,5 9,0 10 ±1,5 grams
with medium grinding (500±60μm) and using coee of test.
2) the 3 grinding times are always:

beside, every grinding time is, respectively:
4,0s ≤T3 ≤10s (10000ms)
