Maintenance
Service the machine on an annual basis, please
refer to your authorised dealer for advice.
Maintenance operations that you can perform
are:
•
Changing the group gasket every 6-9
months, or as required.
•
Washing the internal Water tank, weekly
•
Removal and cleaning of shower screen
•
backflushing with detergent (lubricate group
afterwards)
•
Check for leaks (weekly)
•
Replace a heating element (with dealer
guidance)
The Vesuvius should only be cleaned with non
abrasive cleaners and a soft micro-fibre
(recommended), cloth
In the event of any abnormal operation or
problem with the display or main computer:
Switch the machine off and unplug it. Plug in and
switch on again. If this does not fix the fault, check
all the settings in the advanced menu, in case the
main board firmware has been accidentally returned
to the board manufacturers settings.
If a boiler fails to heat, the machine has 2
resettable limit stats:
Unplug machine and remove either upper or lower
access panel to reset the relevant limit stat, by
pressing the little red button in the centre. The brew
boiler has this on the top, the steam boiler has one
located underneath. If the problem recurs, contact
your dealer for advice.
Abnormal sounds or leaks:
Contact your dealer for advice. Sometimes the
repair may be very simple, e.g. a leaking high
pressure PTFE pipe joint, and the dealer can talk
you through quickly fixing it. At other times it may be
more serious and require the machine to be returned
for repair
Descaling
.
Although descaling can be successfully performed at
home, it is beyond the scope of this manual and we
recommend only suitable filtered or treated water is
used. Please contact your dealer for advice.
Main Board Firmware - Manufacturer Reset
In the unlikely event of you having to perform a reset
of the main board firmware, please use the following
procedure.
Note this will revert the board to the
board manufacturer settings, not factory settings
Switch the power off at the wall socket. Then power
the machine on an Touch the red zones above
simultaneously until a reset message appears on
screen.
PID values Explained
Although we recommend you don't change the
values in the guide. With experience small changes
may benefit the operation of your specific machine.
The P gain stands for Proportional
- it will try to
quickly restore the set point value. Too low, and
response is sluggish, too high can cause
overshoots.
The I gain stands for Integral
- measures change
over time and will add more to the proportional gain
the longer we are not at the set point. Usually only
small values of I are needed, try reducing it if
overshoots/oscillations occur, or increasing I, if the
set point is not reached.
The D gain stands for Derivative
-
Measures
change over speed. It will reduce the effects of P
and I more, the faster the set point is approached. It
acts as a damping factor. Low values of D can
cause overshoots, high values of D can make
response sluggish.
