This setting enables or disables the electronic pre-brewing(See fig.A). By
factory default this option is disabled, as the Brilliance’s brewing groups are
equipped with mechanical pre-brewing systems.
To activate this function press the button (one short espresso),
to disable, press the button
(one long espresso).
To accept the setting and proceed to the next menu, press the
continuous button
.
If in the previous menu the pre-brewing function was enabled, this menus
will appear as to allow the adjusting of the parameters of the pre-brewing. As
said, this machine is already equipped with mechanical pre-brewing, so it is
not to activate this function.
On this first menu, it is adjusted the pre-brewing time for each type
of selection (short espresso, large coffee, 2 short espressos & 2 large
espressos). in which water is pumped as to moisture the grinded coffee.
To adjust it press the button (one short espresso) or
(one long espresso).
To accept the setting and proceed to the next menu, press the continuous
button
.
Now it is adjusted the pre-brewing time for the little pause after the initial
water injection, as to allow the grinded coffee to moisture depending on
each type of selection.
To accept the setting and proceed to the next menu, press the continuous
button
.
Here it can be adjusted the detection sensibility of the level probes of the
boiler. (See fig.D)Normally it is not needed to modify it from the “medium”,
but in some cases (very pure water, this is water with very low level of
dissolved salts), it will be needed to select High sensibility and vice versa.
By default this sensibility will be set to “Med”, and generally it is not needed
to modify it.
To increase sensibility, press the button (one short espresso), to
decrease it, press the button
(one long espresso).
To accept the setting and proceed to the next menu, press the continuous
