check the connection between the machine and the payment

power off the machine and empty the drip tray (see 13.01.);
EAROM of the CPU board failed; replace the CPU board

water inlet solenoid valve in safety status (waste water from the
boiler overflow) or non operating; the internal filter net clogged;
water not supplied by the network, water supply flow rate not
adequate; supply water circuit throttled or clogged; it may
physiologically occur at the first power on when the pressure boiler
that is completely empty will require more time than usual to fill;
(see 05.13.);
there is a control connecting water reloads with the drinks you

any drink, this will produce the 6B error; make sure there is no
leakage in the water circuit;

the brewing pump, at the
expiry of which error 7 is produced; check the efficiency of the
water circuit: volumetric counter, pump, three-way solenoid valve,
…; brewing chamber as well as upper and lower filter of the coffee
brewer; the quantity and grinding degree of coffee shall cause the
machine to brew for about 10/15 seconds;
electrically and mechanically check the switch controlling the coffee
brewer rotation, the control cam, the brewer rotation motor and its
crank;
make sure that the coffee brewer has properly positioned (against
the support wall); check the operation of the micro switch operated
