Note:
!
It normally takes 25–35 seconds to extract a shot of coffee.
!
When the coffee brewing button is turned off, an electric solenoid
valve operates to release the pressure inside the group head.
This also has the benefit of extracting the remaining water from
the coffee cake. The water is expelled into the drip tray, so you
need to regularly empty this tray.
Frothing or heating milk
Froth or heat milk
before
making coffee. This ensures the boiler is at
the optimum temperature and pressure to make coffee.
element indicator light
To froth or heat milk:
1.
Press the steam button. This will
usually
cause
the

button
2.
When the lamp goes out, turn the
steam tap anticlockwise to purge
the steam wand of condensation
by
releasing
steam
into
a
container.
3.
Fill a stainless steel jug with the
required amount of milk. Avoid
filling jug more than half way.
4.
Immerse the tip of the steam wand into the centre of the jug, just
below the surface of the milk.
5.
Turn on the steam tap
anticlockwise
until
you hear a soft “psst-psst” sound, which
indicates the milk is being frothed. As the
milk level rises, lower the jug to ensure the
wand stays just under the surface of the
milk to maintain the “psst-psst” sound.
6.
When the milk is sufficiently frothed, lower the steam wand into
the milk to heat it. Move the wand around the milk to ensure even
heating.
Do not boil the milk!
Correct temperature can be judged by holding your hand against
the jug. When the temperature is too hot to the touch, wait four
seconds or so, then turn off the steam.
7.
Remove the jug and
top up the boiler water level
. To do this:
!
Insert the steam wand into an empty jug and open the steam tap.
!
Press the coffee extraction button until a continual stream of
water flows through the steam wand, indicating the boiler is full.
This will also flush out any milk deposits inside the wand.
!
Wipe the steam wand with a clean damp cloth to remove any milk
before it dries.
