POSSIBLE CAUSES
• T he group x boiler safety
thermostat has been
triggered
• The resistance is
interrupted (cabling defect).
• Triac board fault.
• Thermocuple
disconnected
• Wrong configuration
during standard data in-
sertion.
• R esistanc
alwayspowered.
• Temperature sensor out
of range.
• No water
• Refill EV failure
• Wiring interrupted
• Card failure.
• Electrical fault.
• Leakage to earth.
• coffee filter blocked
• coffee type changed
• qref calibration wrong
• grind too fine,
excessive dose ground.
• coffee type changed
• qref calibration wrong
• grinding too coarse
• grinder/dispenser
blocked, insufficient
dose of ground coffee.
• coffee filter blocked
• coffee type changed
• qref calibration wrong
• grind too fine,
excessive dose ground.
• coffee type changed
• qref calibration wrong
• grinding too coarse
• grinder/dispenser
blocked, insufficient
dose of ground coffee.

VERIFICATIONS and SOLUTIONS
• C heck if the safety thermostat of the group x boiler
has been triggered, and reset it if necessary
• C heck if there are interruptions or detached
fastons on the cabling
• C heck that the group x boiler resistance is not
interrupted and replace it if necessary
• R eplace Triac board.
• E nter in the programming mode and insert the
correct standard data..
• C heck connections.
• R eplace the steam temperature probe.
• C heck cabling
• R eplace the sensor.
• C heck water is supplied from the main line.
• R eplace the refill EV.
•Check cabling.
• R eplace the card.
• C heck wiring.
• C heck, by activating the components individually
on the manual control panel, that the level signal
does not show any anomalies (%).
• wash the group
• clean/replace the coffee filter
• use a coarser grind
• calibrate the machine correctly on the basis of
the coffee/recipe.
• check that there are no external elements in the
grinders
• check that the measure grinder is working (pick-
up current and fuses)
• use a finer grind
• calibrate the machine correctly on the basis of
the coffee/recipe.
