5. Operating Instructions
5.1 Making Espresso
- Ensure the water tank is filled and the machine is plugged in. Press the power button to turn on the machine. Wait for the machine to heat up (indicator light will stop flashing).
- Select the appropriate filter basket (single or double) and place it into the portafilter.

- Attach the portafilter to the group head by aligning it and rotating it to the right until it is secure.
- Place one or two espresso cups on the drip tray directly under the portafilter spouts.
- Press the 'Espresso' button for a single shot or 'Double' for a double shot. The machine will automatically brew and stop.

- Ensure the machine is on and heated. Press the steam button on the touch display. The indicator light will flash while heating and become solid when ready.
- Position the steam wand into the milk, just below the surface.
- Turn the steam control knob to release steam. Move the pitcher up and down to create foam.
- Once the desired texture and temperature are reached, turn off the steam control knob and then press the steam button on the display to deactivate.

6. Maintenance and Cleaning
Regular cleaning and maintenance ensure optimal performance and longevity of your espresso machine.
- Daily Cleaning: After each use, remove and empty the portafilter. Rinse the filter basket and portafilter under running water. Empty and clean the drip tray. Wipe down the exterior of the machine with a soft, damp cloth.
- Steam Wand Cleaning: After frothing milk, immediately wipe the steam wand with a damp cloth. Periodically, remove the tip of the steam wand and clean any dried milk residue with a small brush or needle.
- Water Tank Cleaning: Clean the water tank regularly with warm soapy water and rinse thoroughly.
- Descaling: The machine features an automatic descaling alarm. When the descaling indicator lights up, it's time to descale the machine. Follow the instructions in the descaling solution package and the machine's specific descaling procedure (refer to the full manual for detailed steps). Descaling removes mineral buildup, which is crucial for machine performance and coffee taste.
