POSSIBLE CAUSES
Portafilter not inserted in the
group head correctly.
There are coffee grounds around
the filter basket rim.
Filter basket rim is wet or under-
side of portafilter lugs are wet.
Wet surfaces reduce the friction
required to hold the portafilter in
place whilst under pressure duri-
ng an extraction.
Too much coffee in the
filter basket.
Clock not set.
An error that cannot be reset by
the user has occurred.
This is normal and happens
occasionally. The dry puck fea-
ture creates a slight vacuum on
top of the coffee puck which
will occasionally hold the puck
against the shower screen
instead of leaving it in the filter
basket.
Using de-mineralised or distilled
water which is affecting how
the machine is designed to
function.
WHAT TO DO
Ensure portafilter is rotated
to the right until the handle
is past the centre and is securely
locked in place.
Rotating past the center will not
damage the silicone seal.
Clean excess coffee from the rim of
the filter basket to ensure a proper
seal in group head.
Always ensure filter basket and por-
tafilter are dried thoroughly before
filling with coffee, tamping and inser-
ting into the group head.
Trim coffee dose using the RAZOR™
dosing tool after tamping.
Set clock.

We recommend using cold, filtered
