• When setting the grind size it should be fine but not too fine or pow
-
dery. The grind will effect the rate at which the water flows through the
ground espresso in the filter and therefore the taste of the espresso.
• If the grind is too fine (looks like powder and feels like flour when
rubbed between fingers), the water will not flow through the ground
espresso even when under pressure. The resulting espresso will be over
extracted, too dark and bitter, with a mottled and uneven crema on top.
• If the grind is too coarse the water will flow through the ground espresso too quickly. This will
result in an under-extracted espresso lacking in flavor and without the thick crema on the top.

• When grinding for a Single Wall Filter using a finer espresso grind,
you will need to increase the grind amount to ensure the filter is correct-
ly filled.
• To increase the grind amount, turn the GRIND AMOUNT dial beyond
the DUAL WALL setting to obtain the correct amount of ground espresso.
note:
You may need to try step 4 and 5 a few times, slightly adjusting
the GRIND SIZE and GRIND AMOUNT dials each time until you reach your desired com-
bination.

• Fill the hopper with fresh coffee beans.

fresh ground espresso.
note:
To stop the auto grinding midway through a grinding cycle, push the portafilter in
once, or press the FILTER SIZE button.
• For manual grinding - push and hold the
portafilter in until the desired amount of ground
espresso has been delivered.
