5.2 Frothing Milk

The integrated steam wand allows you to create creamy milk foam for lattes and cappuccinos.

1. Prepare Milk: Fill a stainless steel frothing pitcher with cold milk (dairy or non-dairy) to about one-third full.
2. Position Steam Wand: Submerge the tip of the steam wand just below the surface of the milk.
3. Activate Steam: Turn the control knob to the steam position (right). The machine will begin to produce steam.
4. Froth Milk: Move the pitcher up and down slowly, keeping the steam wand tip just below the surface to create foam. Once the desired texture and temperature are reached, turn the control knob back to the standby position (middle).
5. Clean Wand: Immediately wipe the steam wand with a damp cloth to prevent milk residue from drying. Briefly release steam into an empty cup to clear any internal blockages.

6. Maintenance and Cleaning

Regular cleaning ensures optimal performance and extends the lifespan of your espresso machine.

6.1 Daily Cleaning

• Drip Tray: Empty and clean the removable drip tray and drip plate after each use.
