Before accessing the internal components and, in general, before doing any jobs on the appliance, make sure the power plug has been disconnected and that any heated parts have cooled down. IMPORTANT: The appliance in question has metal parts. We therefore advise being very careful when handling or doing jobs on these to avoid scratches, abrasions or cuts. B / SCOPE OF THIS MANUAL This manual has been compiled for technicians with the skills required to repair coffee machines for home use. Its purpose is to provide details of a general nature regarding the product, to make any jobs and maintenance easier. C / DIMENSIONS 2

oth circuits, hot water/steam and coffee, use the same pump. Hence functions must be performed ort description of the dynamics and operating sequences concerning the three main functions: offee: required dose has been selected and the cycle has been started, powder preparation and - Hot water: been selected, keep the start key pressed for the required dispensing time. er pushed luid still in the team: function has been selected, keep the start key pressed for the required dispensing time. arted, the luid still in the B individually. Below is a sh -C Once the automatic unit positioning is followed by pump operation and the opening of the two solenoid valves. At this point, the water flows through the flow meter which determines the dose, through the pump, the first solenoid valve, the heat exchangers for the coffee and the second solenoid valve and then enters the plastic body of the automatic unit. Here, after passing through the coffee pod, the coffee is collected by the brass part mounted on the same heat exchanger from which it protrudes thanks to a silicone pipe and reaches the dispenser. Once the cycle has terminated, the solenoid valves de-energize and drain the fluid still in the circuit into the drip tray. Once the function has Upon starting the appliance, the pump and the hot water/steam solenoid valve are started, the wat by the pump flows through the first solenoid valve and then enters the hot water/steam exchanger. Once it has crossed the exchanger, it is conveyed to the hot water/steam outlet pipe junction. Once the start key is released, the solenoid valve de-energizes and switches over so the f circuit is drained into the drip tray. -S Once the When the appliance is switched on, the pump and the hot water/steam solenoid valve are st solenoid valve in normal operation and the pump by means of short but frequent pulses. The water pushed by the pump flows through the first solenoid valve and then enters the hot water/steam exchanger. Once it has crossed the exchanger, it is conveyed to the hot water/steam outlet pipe junction. Once the start key is released, the solenoid valve de-energizes and switches over so the f circuit is drained into the drip tray. 3

1) GENERAL ACCESSIBILITY BEFORE PROCEEDING, DISCONNECT THE MACHINE FROM THE POWER MAINS To work inside the appliance, proceed to dismantle as follows: Loosen the screws on the upper part of the appliance Raise and remove the lid as shown in the photo. 5

-A: Top part of the automatic unit to do jobs on the safety thermostat , temperature probe, connections and pipes. -B: Coffee and steam circuit solenoid valves for jobs on coils or pipes. -C: Electronic board for checking cables or changing fuses. -D: Flow meter for internal cleaning or replacement. -E: Anti radio disturbance filter for checks or replacements. -F: Steam junction for replacing O-ring or jobs on pipe or connection. -G: Telescopic dispenser for checking support or replacement apparatus. -H: Steam, hot water exchanger for jobs on safety thermostat, temperature probe or pipes. 2) AUTOMATIC UNIT COMPARTMENT ACCESSIBILITY 6

by removing the right section of the bodywork for bigger jobs. -SERVICE DOOR: Only technical personnel must access the appliance through the service door. For greater safety, the closing screw is of the TORX M4x10 type and consequently a suitable screwdriver is required. Remove the screw and open the door to make necessary inspections. -REMOVAL OF RH BODYWORK: Remove the two screws on the rear. Remove the four screws on the side. 7

Remove the grinding regulation knob as shown. Now the entire RH section can be removed and access obtained to the unit and the micro switches of the side doors and dredge unloading. The photo shows the two micro switches of the door and dredge unloading. The micro with three attached wires also sends a signal to the board for dredge count reset. 8

downstream of the master switch. If jobs have to be done on the automatic unit, disconnect the delivery and exit pipes of the exchanger, proceeding as indicated under “QUICK-COUPLING CONNECTIONS”. Remove the power connections. 9

Loosen the upper retention screw of the unit introducing the tool through the holes shown in the illustration. Loosen the lower retention screw as shown in the illustration. 10

When fitting the automatic unit back on, be careful to correctly fit the pin of the same unit on the motor shaft as shown in the illustration 3) COMPONENT COMPARTMENT ACCESSIBILITY 11

the illustration. Once the tank support has been removed, loosen the two side screws as shown in the illustration. Loosen the retention nut of the pump- grinder support indicated in the photo. 12

Loosen the screw shown in the photo. Remove the five retention screws shown in the bottom of the machine. 13

Remove the left side bodywork Besides now being able to freely access all the machine parts, the main fuse located on the base can also be changed. G) QUICK-COUPLING CONNECTIONS 14

of the machine. To use these correctly, do not use tools but only your fingers. The first thing to do to disconnect a hose is to lightly press on the edge of the connector. Afterwards, simply apply a light force on the hose to remove this. H) SAFETY THERMOSTAT RESET 15

reset. To reset, press the top button. 16
