No particular instructions (to be confirmed with the new dampers).
Tamping head
Can be disassembled without removing the technical mount: be careful not to offset the
tamping head mount when unscrewing.
Æaccess to the coffee outlet grid, the creamy seal and the tamping head seal.
Switch control plate on the actuator
Unclip the 2 clips (access from the top).
Compress the actuator by pressing on the top nut
(using a socket spanner or equivalent).
Disassemble the switch control plate.
Flowmeter
No particular instructions.
Power electronic board
Electronic circuit mount maintained in the shroud by means of 2 clips at the lower part.
Control electronic board
Use an antistatic wriststrap
Remove the facing (2 screws + 4 clips accessible via side holes).
On the graphic model, it is possible to replace the display device (take particular care when
disconnecting the bundle on the elctronic board).
Fuse
To access, remove the facing panel (2 screws in the lower part + 2 screws in the technical
mount).
Raise the technical mount so as to disconnect the 2 bushings in the facing panel.
Determine why the fuses blew before replacing.
Check that there are no blow traces on the base and the tamping head.
3

Coffee nozzle
Unclip the coffee pipe.
Remove the nozzle clip by means of a rule or a screwdriver placed between the clip and the
facing mount:
Clip
Technical mount: (provides access to the distributor and thermoblock/actuator sub-assembly)
Unclip and remove the coffee inlet pipe and disconnect the hose on the tamping head.
Remove the window.
Remove the mounting screws from the technical mount.

Ensure that wires go through the grommets.
NB: check that the brass spacers are mounted in the grinder screwing holes.
Check the ground coffee cake thickness after any work carried out on the grinder or electronics.
It is possible to adjust grinding time electronically to obtain specified cake thickness: 11 to 13 mm for
60-ml strong espresso.

Lead
Respect the earthwire routing.
The lead earthwire must not be in contact with moving parts (stainless steel corners behind the
actuator) or hot parts (resistor and lug connectors)
Wiring
Grommets are to be respected in order to comply with interference suppression requirements:
generally speaking, wires which ensure power transmission (thermoblock, pump, grinder) are not
routed the same way as low voltage / low current wires.
Wires are arranged in the following order:
1. - 2 green water-level wires + 3 red flowmeter wires
2. – control board connector
3. - 2 blue NTC wires
4. - 2 green draw switch wires
5. - 2 blue-red distributor motor wires + 3 black-yellow-white distributor switch wires
6. - 2 grinder wires
See wiring photos in enclosed document.
7

Pump
Respect the direction of the clamp closing device on the pump outlet (risk that this might get in the way
of the cake tray housing).
Flowmeter
Respect the connections:
pump tube on the flowmeter lid
tank tube on the flowmeter casing.
Hoses must not be twisted or bent.
Thermoblock-actuator sub-assembly
Direct the device for closing the clamp on the actuator pipe downwards (risk that this might get in the
way of the ejection scraper).
actuator
Tamping head
When screwing, be careful not to offset the tamping head mount.
Thermoblock and ejection scraper interface
Take care when replacing the seal which must not protrude into the coffee chamber.
.
Distributor
Replace the 2 pins of the drain receptacle properly in the 2 holes of the base.
Check that all hoses are tightly connected, in particular the easily detachable drain hoses, and that the
clamps are properly clipped onto the high-pressure hoses.
Check that the drain hose is not bent or caught.
The ejection rod "Barista" seal
Ensure that re-assembly is made the correct way up (lip facing upwards).
Only grease the ejection rod, and sparingly, with food grade grease.
8

Distributor drain casing
Be careful to centre the spring properly on the bushing at the bottom of the drain body (risk that it
might catch on the notches).
The drain plunger must be mounted in the body of the drain with food grade grease.
Ensure that the drain body is firmly locked down on the distributor (tighten counterclockwise).
Electronic boards
Connectors on electronic boards: check that connectors are well secured by the clips.
Check the coffee volume selector button for correct indexation (1/2 turn possible error).
Check ground coffee cake thickness after any work on electronics or the grinder.
Steam nozzle
Be careful when replacing the O-ring as this is a delicate operation.
Body
There is a risk that switches might catch on the cake tray housing inside the body: press the body
down firmly when replacing.

SERVICING AFTER CLOGGING-UP OF GROUND COFFEE
Remove the cleaning inlet and the drawer.
Scrape and suck up the ground coffee in and around the thermoblock tank using a vacuum cleaner
with a small end piece (flexible hose with ~10 ext. diameter).
Carry out a cleaning cycle:
If the ejection ram works properly in the tank ÎOK
If it sticks, activate manually with a rod inserted through the base:
Check that the drawer switch works properly: any ground coffee in the drawer slide channels could
affect the control. If this is the case, remove the technical mount to clean the slide channels.
Renew a cleaning cycle.
Determine the reason why clogging-up occurred (see troubleshooting diagnosis table):
grinder not compliant (quantity of ground coffee)
electronics setting not compliant with the grinder
ejection ram stuck in high position
cake tray replaced partially full
CLEANING AND SCALE REMOVAL CYCLES
The cleaning light comes on after 350 coffees (or espressos).
The scale removal light comes on after:
•12,000 cycles with water hardness setting 0
•10,000 cycles with water hardness setting 1
•8,000 cycles with water hardness setting 2
•6,000 cycles with water hardness setting 3
•3,000 cycles with water hardness setting 4
with:
•1 coffee (or espresso) = 1 cycle
•1 "steam" function = 25 cycles (V16 picto power board and V6.8 to 7.0 Visu display)
= 40 cycles (V17 picto power board and V7.2 Visu display)
•1 "hot water" function = 10 cycles
The number of cycles is doubled when a filter is used (progamming in the display version).
