• When the auto grind, dose & tamp function is
complete, rotate the portafilter handle to the
INSERT position and lower to remove.
• Wipe any excess coffee from the rim of the
filter basket to ensure a proper seal in the
group head is achieved.
PURGING THE GROUP HEAD
Before placing the portafilter into the
group head, run a short flow of water through
the group head by pressing the
1 CUP button. Allow water to flow for
5 seconds, then press the 1 CUP button again
to stop the flow of water. This will purge
any ground coffee residue from the group
head and stabilize the water temperature
prior to extraction.
INSERTING THE PORTAFILTER
Align portafilter handle with the INSERT
position on the group head. Lift to insert
portafilter into the group head and rotate
towards the LOCK TIGHT position until
resistance is felt.
EXTRACTING ESPRESSO
• Place pre-warmed cup(s) beneath the
portafilter spouts and press the 1 CUP
or 2 CUP button.
• As a guide, the espresso will start
to flow after 7-12 seconds (this includes pre-
infusion time) and should be the consistency
of warm dripping honey.
• If the espresso starts to flow before
7 seconds, the grind is too coarse. This is an
UNDER-EXTRACTED shot. Adjust the grind
size slightly finer.
• If the espresso starts to drip or flow after 12
seconds, then the grind is too fine. This is an
OVER-EXTRACTED shot. Adjust the grind
size slightly coarser.
A great espresso is about achieving the
perfect balance between sweetness, acidity
and bitterness.
The flavor of your coffee will depend on many
factors, such as the type of coffee beans, degree
of roast, freshness, coarseness or fineness
of the grind.
Experiment by adjusting these factors
just one at a time to achieve the taste
of your preference.
