protocol
no communication between the payment system and the vending machine
CPU; it might be caused by improper power supply, false programming or
payment system malfunction;
the contact controlling the liquid level in the drip tray is closed because
liquid level;
EAROM those integrated in the CPU board fail to operate properly;
air break filling time too long; the water supply might be totally lacking, its
pressure might be not enough or some obstacle might slow down the
regular water flow (filter grilled cover, load pipes either choked or
clogged); the water inlet solenoid valve safety has tripped;
the pressure boiler circuit has been refilled with water, but no drink has
been dispensed; the supply circuit might have a leakage;
during the first installation phase, water inlet error in the machine; after
having opened the water inlet solenoid valve and activated the pump, the
volumetric counter shall send the CPU a sequence of pulses to give
evidence that water is flowing; if this does not occur, error 6G is triggered;
the power-on time of the espresso circuit pump has exceeded the limit; the
water flow has encountered more resistance than usual and the pulses
produced by the volumetric counter have required a time interval deemed
to be too long for a dispensing cycle within proper limits; also check the
grinding amount and degree of coffee beans poured into the coffee brewer
chamber;
initial positioning error;
the machine fails to recognise the presence of the coffee brewer in its
correct working position;
the brewing chamber is not moving properly;
