PROBLEM
POSSIBLE CAUSES
EASY SOLUTION
Espresso runs out too
quickly.
• Coffee is ground too coarsely.
• Use slightly finer grind. Refer to
‘Setting the Grind Size’, page 13 and
‘Under Extraction’, page 17.
• Not enough coffee in the filter
basket.
• Increase dose of coffee. Refer to
‘Setting the Grind Amount’, page 13
and ‘Under Extraction’, page 17.
• Coffee tamped too lightly.
• Tamp between 15–20kg of pressure.
Espresso runs out around
the edge of the portafilter.
• Portafilter not inserted in the
group head correctly.
• Ensure portafilter is completely
inserted and rotated until resistance
is felt.
• There are coffee grounds around
the filter basket rim.
• Clean excess coffee from the rim of
the filter basket to ensure a proper
seal in group head.
• Too much coffee in the filter
basket.
• Lower dose of coffee. Refer to ‘Setting
the Grind Amount’, page 13.
• The silicone seal surrounding
the shower screen needs to be
replaced to ensure the portafilter
is properly secured into the
group head.
• Refer to ‘Using the Allen Key’,
page 29.
No steam.
• Machine has not reached
operating temperature.
• Allow time for the machine to reach
operating temperature. The STEAM/
HOT WATER light will flash to
indicate the machine is heating
to create steam. During this time,
condensed water may purge from the
steam wand. This is normal. When
the STEAM/HOT WATER light
stops flashing the steam wand is
ready for use.
• Water tank is empty.
• Fill tank.
• Water tank is not fully inserted
and locked into position.
• Push water tank down completely to
lock into place.
• Machine needs to be descaled.
• Refer to ‘Descaling’, page 25.
• Steam wand is blocked.
• Refer to ‘Cleaning the Steam Wand’,
page 27.
• STEAM/HOT WATER dial is
not in the STEAM position.
• Ensure the STEAM/HOT WATER
dial is completely rotated to the
STEAM position.
