The Solution
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
basket mesh (see: 'Cleaning the Filter Basket and Porta-
filter').
Descale the machine (see: 'Descaling the Machine').
See: 'Special Features for Advanced Users'.
