The Solution
Clean excess coffee powder from the rim of the filter bas-
ket before assembling the portafilter to the group head to
ensure a proper seal.
Moisture reduces the friction between portafilter and group
head. Always ensure that filter basket and portafilter are
completely dry before filling in coffee powder and before
installing the portafilter at the group head.
Ensure that you have selected the correct filter basket
for the amount of coffee powder used. Only level up the
measuring spoon, when filling. Do not tamper the coffee
powder in the measuring spoon (see: 'Filling the Filter
Basket').
Apply the correct pressure (15-20kg) when tamping the
coffee powder in the filter basket (see: 'Filling the Filter
Basket').
Ensure to use the correct amount with the appropriate
filter basket (see: 'Filling the Filter Basket').
Clean the group head (see: 'Cleaning the Group Head').
Get in contact with an authorized service centre for
examination and repair.
Fill the water tank. The filling level must be between
250 ml and 1500 ml (MAX).
Use coffee powder suited for espresso machines. Adjust
your coffee grinder accordingly (see: 'Tips for Best
Results'). Pre-ground coffee powder is labelled accordingly.
Ensure that you have selected the correct filter basket for
the amount of coffee powder used. Measure the amount
of coffee powder via the measuring spoon (see: 'Filling
the Filter Basket').
Clean the filter basket. You may use a needle or the fine pin
of the cleaning tool to open clogged holes in the filter bas-
ket mesh (see: 'Cleaning the Filter Basket and Portafilter').
