Gauge
•
The gauge on the left is for your boiler steam pressure. After turning the machine on it
will take approximately 15 minutes before the gauge will show any pressure. Once up
to pressure the gauge will cycle back and forth roughly between 1.2-1.7 bar
depending on the steam boiler temperature setting. Should you need to adjust the
steam pressure please refer to the PID section of the owner’s manual.
•
The gauge on right is for your pump (brew) pressure. When sitting idle the gauge is
reading trapped pressure in the system and may vary. To get an accurate pump
pressures reading, activate the pump by lifting the brew lever. You may also check
the pump pressure by installing your backflush disc in the portafilter and lock it into
the grouphead and then raise the brew lever. After a few seconds the pressure should
rise to about 9 bar. When you make espresso the pressure on the gauge will be
slightly less at about 8.5 - 9. bar which is normal. This can be helpful in setting up
your grinder. If your pressure goes to 9 bar with the backflush disc, but when you
make espresso it is less than 8 bar then that means you need to go finer with your
grind which will create more resistance to raise the pressure. Should you need to
adjust the pump pressure please refer to the maintenance section of the owner’s
manual for instructions on setting the pump pressure.

Lights
•
On the front of the machine there are 4 indicator lights. The white indicator lights
illuminate whenever the coffee boiler or the steam boilers are turned on.
•
The Red indicator lights indicate when the boiler is heating. It is normal for these lights
to flash rapidly back and forth when the PID is maintaining the proper temperature in
both boilers.
Pump
•
The machine is equipped with a rotary pump that is mounted underneath the motor so
as to protect the motor in case of pump failure.
