Priming the water circuit
! Before starting the machine after long periods
of inactivity, if the water tank has been completely
emptied, it is essential to prime the machine circuit.
The circuit must be also primed every time the display
shows:
VENTILATE
1. To prime the circuit,
direct the steam spout
over the drip tray.
Place a cup or suitable
container below the
steam spout and press
the
key.
2. Wait until the water runs smoothly out of the steam
spout. To interrupt, press the
key.
After the above operations have been completed the
machine is ready for use.
To dispense coffee, hot water or steam and for proper
use of the machine, carefully follow the instructions
that are provided.
Regulating water hardness
Regulate the machine to the right degree of water
hardness that you will use.
According to this setting, the machine advises when it
is necessary to run a descaling cycle.
Read the sections on “Water hardness” in “Program-
ming” to regulate hardness.
Grinding regulation
! Take care when rotating the knob that regulates
grinding, which is located above the brewing unit. Do
not put ground and/or freeze-dried coffee in the bean
container.
! Do not put any material other than coffee beans in
the container.
Switch off at the mains before carrying out any type of
operation inside the machine.
The quality and flavour of coffee depend on the
grinding level, as well as the blend used.
The machine has a knob to regulate the coffee
grinding.
To regulate the grinding,
turn the knob one
setting at a time. The
figures indicate the
fineness of the grind.
The manufacturer
configures each
appliance on an
intermediate grinding
setting. If the grind is
too fine, rotate the knob to a higher setting; if the grind
is too coarse, turn the knob to a lower setting.
The variation in grind will only be seen after one or two
coffees have been brewed.
Use coffee bean blends for espresso machines. Try
not to use high grinding settings (e.g. 1/10). Use
different coffee blends for these settings. Keep the
coffee in a fresh place in a sealed, airtight container.
Grinding must only be regulated if coffee is not brewed
properly:
• if it is brewed too fast, this means that the grind is
too coarse; turn the knob to a lower setting;
• if it is brewed in drips and/or intermittently, this
means that the grind is too fine; turn the knob to a
higher setting.
