4. First Use / Priming
Before first use, or if the machine has been unused for a long period, prime the circuit by dispensing hot water through the steam wand until water flows continuously. Refer to the detailed instructions in the full manual for specific priming steps.
Operating Instructions
1. Grinding Coffee
- Select your desired grind setting using the grind selector dial. Finer settings are typically for espresso, coarser for other methods.
- Insert the portafilter into the grinding outlet. The machine's Sensor Grinding Technology will detect the portafilter and begin grinding.
2. Tamping
The integrated Smart Tamping System ensures consistent pressure. After grinding, pull the tamping lever down firmly until it clicks, then release. This compacts the coffee grounds evenly in the portafilter.
3. Brewing Espresso
- Insert the portafilter into the brew group and turn it to the right until it locks into place.
- Place one or two cups on the drip tray beneath the portafilter spouts.
- Select your desired coffee temperature using the temperature button.
- Press the '1-cup' or '2-cup' button to start brewing. The Dynamic Pre-infusion and Active Temperature Control Technology will optimize the extraction process.

- Fill a milk jug with cold milk.
- Position the steam wand into the milk.
- Turn the steam dial to activate the steam. Move the jug to create desired milk texture for lattes or cappuccinos.
- Once finished, turn off the steam dial and clean the steam wand immediately.
