Lights
On the front of the machine there are 3 indicator lights. The green power light on the
left will illuminate when the machine is in either the “
I
” FILL mode or “

” ON mode.
On the right side of the machine is the red heating indicator light. The red light will
illuminate every time the heating element is energized. On heat up the light will
remain on for up to 15 minutes and then will cycle on an off approximately once a
minute to maintain proper boiler pressure.
Also on the right side of the machine is the green ready indicator light. The green
ready light also works in conjunction with the heater, but instead the green ready
light will illuminate whenever the heater has turned off after reaching the proper
boiler pressure. This light will also cycle on and off approximately once a minute with
the red heating light in order to maintain proper boiler pressure.
Pump
The machine is equipped with a 52W vibratory pump. Vibratory pumps can be loud
by nature and their tone may change during the course of a shot which is normal.
Periodically the pump will come on by itself to maintain the proper water level in the
boiler. Sometimes the pump will come on when you turn on the machine and
sometimes it may not depending on the water level in the boiler which is normal.
The pump (brew) pressure is regulated by the expansion valve. To learn how to set
the pump pressure please refer to the maintenance section of the owner‟s manual.
The pump is equipped with a klixon thermal fuse. Should the pump run for an
extended period of time the klixon will kill power to the pump until it has cooled off.
