there is a control for the maximum grinding time; after this
threshold has been exceeded, error 9 is produced; no coffee,
hopper orange blade closed; wear, grinders excessively closed;
the values written in the EAROM are not compatible with the
operation of the machine or deleted; reload them; replace the CPU
board CPU; (see 05.39.a.);
there is a control causing the machine to reload water after a well-
defined number of dispensing cycles; otherwise, error 14 is
produced; make sure that the water supply from the outside is
correct (see 03.03.) and that the water circuit of the machine is
orderly (tubes, gaskets, …);
check the display board (see 05.39.b.);
a key of the selection keyboard is not operating (short-circuited); it
may also occur if an operator should operate it for too long while
programming the machine (keys 4 and 5 to increase and decrease
the quantities); (see 05.02. e 09.01.a.);
the 24 V dc power supply should exceed the limit value; replace
the
CPU board (see 05.39.a.);
after al long inactivity, if this error happens, could be enough to
switch off and switch on the machine; if the power failure persists,
pay attention to the cause: a 24 V actuator could be faulty (mixer
or product motor, water inlet electrovalve, …); check the alternate
power supply at the board input; the voltage regulator might be
faulty; replace the CPU board (see 05.39.a.);
the pressure boiler temperature has exceeded the one you have
programmed (see 09.01.e.); replace the temperature probe; the
device of the CPU board is not working according to control;
replace the CPU board;
temperature safety devices tripped (clicsons,, …); restore or
replace them; heating element not supplied or not operating; check
the connections and continuity of the heating element; if
necessary, replace it;
temperature probe interrupted; connector to the board, wiring;
make sure that the cable between the probe and the CPU board is
not interrupted or replace the probe;
