12. Wait until the grinder stops automatically or stop the grinder manually by pres-
sing the grinder button again. Then pull the portafilter out of the grinder cradle
and use the tamper for pressing the coffee powder into the filter basket (see:
‘Tamping the Coffee Powder’).
FILLING IN COFFEE POWDER MANUALLY
IMPORTANT - Only use coffee powder that is suited for espresso machines with a
sufficiently fine grind size. If the grind size is too coarse, your coffee will be weak
and watery. Do not overfill the filter basket. After tamping, above the surface of
the coffee powder there must be 2-3mm of free space to the rim of the filter bas-
ket. For filling, you may use a measuring spoon. Do not fill coffee powder into the
POD filter basket. This filter basket is for coffee pads only.
13. Ensure that the filter basket and portafilter are completely dry. Otherwise, during
extraction, the water may miss the coffee powder and flow at the rim of the filter
basket.
14. When using the filter basket for 1 cup or 2 cups: For your first tries, we recom-
mend to fill in 6-8g coffee powder for extracting 1 cup of espresso.
15. When using the POD filter basket: Place the coffee pad into the filter basket and
push the coffee pad towards the bottom of the filter basket with your fingers.
Ensure that the strips of paper stick to the internal surface of the filter basket. The
coffee pad must be well centred inside the filter basket and the rim of the coffee
pad may not protrude the rim of the filter basket. Otherwise, the water runs out
during extraction and the machine cannot apply the required pressure.
NOTE
If the coffee pad is somewhat too large for the filter basket, you may fold in the
rim of the coffee pad.
IMPORTANT - Only use 1 coffee pad for each extraction. If required, extract 2
espressi one after the other.
TAMPING THE COFFEE POWDER
16. Distribute the coffee powder as evenly as possible. Carefully tapping at the sides
of the portafilter may be useful.
17. Tamp the coffee powder via the tamper of the appliance. Try to get an even
surface that leaves at least 2-3mm of free space to the rim of the filter basket.
NOTE
Tamp down firmly, applying a force of approx. 5 kg. When pressing too hard, the
water flows too slowly and the espresso gets bitter and dark. When pressing too
timid, the water flows too fast, leading to a weak and watery taste. However, the
force for pressing is not as crucial as the evenness of the surface.
18. If you have filled in too much coffee powder, use any flat tool for scraping off
some coffee powder. Then tamp the remaining coffee powder again for getting
a smooth surface.
19. Thoroughly remove any excess coffee powder from the rim of the portafilter.
Otherwise, leakage between portafilter and group head could occur during
extraction and the pump cannot apply sufficient pressure.
INSTALLING THE PORTAFILTER
20. Before inserting the portafilter into the group head, run some water through the
group head by pressing the 1 cup button. This will purge any residues of ground
coffee from the group head and stabilize the temperature of the heating block
prior to extraction. You may use this water flow for pre-heating the cup.
21. After the purging cycle is finished, hold the portafilter with the handle in the 8
o'clock position on the group head. The correct position is marked via an open
lock icon at the group head. Move the portafilter up for inserting it into the group
head.
22. Rotate the handle of the portafilter to the right until you feel the resistance, caused
by the sealing ring at the group head. Ensure that the portafilter is locked secu-
rely to the group head.
STARTING THE EXTRACTION
WARNING – Do not remove the portafilter during extraction. Otherwise,
hot water and steam may be pressed out at the rim of the portafilter. Before remo-
ving the portafilter at the end of the extraction cycle, wait for the system to release
the pressure, You will hear a hissing noise. Thereafter, you may remove the porta-
filter.
23. For filling 1 cup: place the cup on the drip tray centred below the portafilter.
When filling 2 cups: place two cups directly next to each other on the drip tray,
ensuring that one spout of the portafilter lies over each cup.
