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 sensor controlling the liquid level in the drip tray has tripped; empty it
and re-position it;
those integrated in the CPU board fail to operate properly;
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;
error in the lower piston movement down or in the upper piston movement
up;
the machine fails to recognise the presence of the coffee brewer in its
correct working position;
the upper piston is not moving properly;
the lower piston is not moving up properly to the chamber;
the lower piston is not moving down properly;
