chosen button has been programmed.
4 The button for hot water is programmed in the same manner as the coffee buttons.
• Please note that the doses can vary if different quantities of coffee are used for coffee
preparation or if the imposed pressure on the coffee is different while tamping.
• Every button can be re-programmed at any time.

5.3 Activation of the pre-infusion

During pre-infusion, the ground coffee is completely moistened before espresso extraction so that it can
expand evenly in the portafilter. This makes the coffee puk more compact, preventing channels (channelling)
from forming in the puk caused by the high brewing pressure. This ensures a reliable uniform espresso base,
allowing better control over the taste of the espresso when making other adjustments during extraction
process.
Please follow below steps to activate the pre-infusion:
Only the left brew group is used to set up pre-infusion.
1 The machine is turned off.
2 Depress button 2 (1 espresso) and at the same time switch the machine on. The lamp of that button
becomes illuminated. Release the button.
3 Turn the machine off.
4 When the machine is then switched on again, the pre-infusion on all brew groups is activated on buttons
2 (1 espresso) and 3 (large cup) only. No provisions for a pre-infusion have been made for buttons 4
and 5.

5.4 Deactivating the pre-infusion

Please follow below steps to deactivate the pre-infusion:
Only the left brew group is used to deactivate pre-infusion.
1 The machine is turned off.
2 Depress button 3 (1 large cup) and at the same time switch the machine on. That button becomes
illuminated. Release the button.
