4. WORKING PRINCIPLE
4.1. MICROSWITCHES, SENSORS AND SOLENOID VALVES
MICROSWITCHES
Function
Logic
M1 = UPPER MICROSWITCH
Detects when the infuser is on top
position
“NC”, it opens when the infuser is in top
position
M2 = LOWER MICROSWITCH
Detects when the infuser is on down
position
“NO”, it closes when the infuser is in down
position
M3 = DRAWER MICROSWITCH
Detects when the drip tray is in
correct position
Changeover micro switch. When the drip
tray is inserted:
- the contact for the drip tray
detection is OPEN;
- the contact for the transmission
motor power supply is CLOSED.
M4 = WATER TANK
MICROSWITCH
Detects the presence of the water
tank
Changeover micro switch. When the water
tank is inserted:
- the contact for the water tank
detection is OPEN;
- the contact for the transmission
motor power supply is CLOSED.
M5 = IFD CONNECTOR
MICROSWITCH
Detects when the IFD connector is
attached to the machine
“NO”, it closes when the IFD connector is
attached.
M6 = MILK JUG LID
MICROSWITCH
Detects when the milk jug lid is
attached to the machine
“NO”, it closes when the milk jug lid is
attached.
M7 = HOT WATER SPOUT
MICROSWITCH
Detects when the hot water spout is
attached to the machine
“NO”, it closes when the hot water spout is
attached.
REED AND ENCODER
Function
Logic
REED SENSOR LOW WATER
TANK
Detects when the water level is at
minimum
HALL SENSOR ENCODER
Detects rotations of transmission
motor
MILK PRESENCE OPTICAL
SENSOR
Detects when the milk jug contains
milk and when it is empty
- When the jug is connected and
contains milk, the milk presence
blocks the infrared beam
generated by the sensor and the
machine enables the milk
recipes preparation.
- When the jug is connected but it
is empty, the infrared beam
generated by the sensor is free to
pass and the machine disables
the milk recipes preparation. In
this case only the milk jug
cleaning function is active.
SOLENOID VALVE
Function
Logic
EV1 SOLENOID VALVE
3-Ways solenoid valve
It opens to deliver hot water through the
hot water spout and steam to the milk jug
for milk frothing. When it closes, it allows
the discharge of the residual pressure to
the expansion chamber and drip tray.

4.2. COFFEE DELIVERY
Espresso delivery steps:
- Thermoblock is activated
- Grinder is activated for a certain timing (based on the coffee taste selection)
- Infuser moves to the mechanical valve
- Pump is activated for a couple of seconds for pre-infusion
- Pump restarts for coffee delivering
- Pump and thermoblock stop
- Infuser moves away from the mechanical valve and releases the coffee pod
- Mechanical valve discharges excess water/coffee to the grounds container
- Infuser is moved back to the “Coffee Ready” position
Cold water
Hot water

4.3. HOT WATER DELIVERY
Hot water delivery steps:
- Thermoblock is activated
- EV1 solenoid valve is activated
- Pump is activated in fast pulsing mode for a certain timing
- Hot water is delivered through the hot water spout connected to the accessory nozzle
- Pump stops, EV1 and Thermoblock are deactivated
Cold water
Hot water
Discharge

4.4. MILK FROTHING PREPARATION
Milk frothing preparation steps:
- Thermoblock is activated (setting temperature higher than 100°C)
- EV1 solenoid valve is activated
- Pump is activated in slow pulsing mode for a certain timing
- The steam is delivered to the milk jug attached to the accessory nozzle. Here it mixes with milk and
air to produce hot frothed milk.
- Pump stops, EV1 and Thermoblock are deactivated
Milk jug cleaning procedure:
- Thermoblock is activated
- EV1 solenoid valve is activated
- Pump is activated in very slow pulsing mode
- Hot water is delivered through the milk jug lid to clean its internal circuit
- Pump stops, EV1 and Thermoblock are deactivated
Cold water
Steam
Discharge

5. TEST MODE
5.1. PROCEDURE TO ACTIVATE TEST MODES
- The appliance must be plugged-in and in stand-by mode.
- Remove the drip tray. The GROUNDS CONTAINER icon will flash
- Hold the combination of the below three button pressed (depending on the model):
ECAM29X.6Y
ECAM29X.8Y
until the GROUNDS CONTAINER icon will turn OFF and the LEDs of the below buttons (depending
on the model) will start flashing:
ECAM29X.6Y
ECAM29X.8Y
