The display indicates the
message
“Volumetric counter”
(Wheel)
The expected liquid dose is not reached (computed)
within 60 seconds from starting the selection.
The water amount for both espresso coffee
and instant drink selections is ensured by a
volumetric counter; with the water flow
(drawn by the pump) a wheel rotates and
through an electronic sensor sends a number
of pulses, and when the number of pulses
corresponding to the water dose set during
programming is reached, the pump is
stopped.
If such value is not reached within 60 sec it
means that there is a problem:
Then, check for the correct functioning of the
volumetric counter; there must be 5 V AC on
the terminals during the counter operation.
Check that the filters are not clogged.
Check that the by-pass is not locked open.
The display indicates the
message
“Air-break failure”
No water from the mains.
Faulty air-break microswitch
Failure to the level detection system (float)
If in the period taken to make any 6
selection the microswitch controlled
by the float is not triggered, the
vending machine is locked for air-
break failure.
The malfunction could occur for lack of water
from the mains, or because of a failure to the
float/microswitch system.
Replace the microswitch with one that MUST
HAVE the same characteristics.
Otherwise various malfunctions could occur.
The display indicates the
message
“RAM data”
System lock
Wrong RAM data, which must be retrieved by
initialising the EPROM.
Access the installation procedure and initialise
the Software.
If the problem persists, replace the entire
CPU board.
The display indicates the
message“
Coin mech
failure
”
If the ere is no communication between coin
mechanism and CPU board for 30 seconds (for
serial coin mechanisms only)
Check for correct connection and
configuration of the minidips, if all correct
replace the coin mechanism.
The display indicates the
message
“Water failure”
Models with water supply from the mains:
If the air-break microswitch is activated for more
than a minute
Models with water supply from an internal tank:
If the water level is less than 300 cc
Check the water inlet solenoid valve.
Check the correct actuation of relay
K 16
Check the air-break microswitch functioning.
Check the float/microswitch system
functioning.
Coffee is dispensed too
slowly
and it tastes burnt
Faulty pump by-pass (open)
Clogged coffee filters.
Excessive temperature in the flow-through boiler
Flow-through coffee boiler clogged
Replace the by-pass valve with one set at 10
bars. Consider that coffee must be dispensed
in a maximum time of 15 to 20 seconds;
longer times can clog the filters.
The coffee is dispensed too
quickly
and lacks body and
cream
Faulty pump by-pass (closed)
Insufficient temperature in the flow-through boiler
Faulty heating element in the heating pipe
Replace the by-pass with one set at 10 bars.
Check for the correct temperature, which
must be between 95° and 97° C.
Check that there is flow in the dispensing
tube and that the temperature is at least 60°
C.
Check the functioning of the specific power
supply board.
Check that the thermo-fuse was not
triggered; if triggered replace with one
having the same characteristics.
The mixers
clog up
The whipper failed to rotate
Powder removal drawer full
Insufficient water to powder ratio.
Check for the mixer motor overheat
protection trigger, if that is the case check
the cause of such trigger. Empty the powder
collection drawers and check the functioning
of steam suction fan.
Check the powder/liquid setting
