8 – TROUBLE-SHOOTING
Problem
(and/or indication on the
display)
Possible cause
Solution
The machine does not go into
the heating phase, remaining
in the installation phase
No water flow from the mains or insufficient
pressure (it must be 5-85 N/cm
2
)
The air-break microswitch is faulty
Water inlet solenoid valve blocked by the overflow
drain of the air-break.
Water inlet solenoid valve not activated because of
faulty RELAY K16
Check the presence of one or more of
situations indicated and once identified the
cause do as follows:
Short-circuit the air-break microswitch to
check its functioning
In the event of failure, replace with a new
that MUST HAVE the same characteristics
Unlock the water inlet valve, undoing the
threaded ring and emptying the overflow
tube
Check for 230 V AC voltage at the power
supply terminals
Check the activation of relay K16
The display indicates the
message
“No coffee”
Coffee pod spent or faulty pod detection
microswitch
Faulty “SERVING” drive motor
Pod drive locked
Faulty RELAY K7
When a coffee selection is made, the
“SERVING” drive ratiomotor is activated, and
the movement activates a microswitch. If
such microswitch is not activated within 5
seconds, the SW disables all coffee based
functions.
Check for one or more of the situations
indicated
The display indicates the
message
“Boiler failure”
The boiler does not reach the operating
temperature
Faulty temperature probe
Overheating protection triggered
For the espresso boiler, melted thermo-fuse
The vending machine is locked if the set
temperature is not reached within 10
minutes.
Check the correct operation of the heating
element, the probe and of the actuation triac.
NOTE:
1) at 25° C the probe must have a resistance
of 12 k ohm
2) at 100°C C the probe must have a
resistance of 963 ohm
(± 4 ohm tolerance)
3) In the event of faulty flow-through boiler,
the problem is not signaled by the SW,
therefore it must be checked whether the
thermo-fuse was triggered or the failure is in
the power supply board (specific)
The display indicates the
message
“No cups”
No cups in the dispenser
Faulty cup detection microswitch
Faulty RELAYS K13-15
If no cups were present when starting the
machine, the column rotation ratiomotor is
activated to search for a full column and if no
cups are found within a 60 sec (indicated by
the specific cup detection microswitch) the
machine is locked.
Excluding the fact of a real lack of cups, the
correct microswitch functioning must be
checked and in the event of failure it MUST
BE replaced with an identical one.
In the event of locked release motor or
column motor, check for the correct actuation
of relays K13-15.
The display indicates the
message
“Brewer unit”
The unit failed to reposition.
Faulty unit positioning microswitch (upper dead
centre)
Faulty unit positioning microswitch (lower dead
centre)
Faulty RELAY K5
Check the correct functioning of the upper
and lower position microswitch using a
multimeter
In the event of correct functioning, check the
correct setting.
In the end, check the correct setting of the
adjustable rod that closes the brewing
chamber.
