4.2. Grinding Coffee Beans

4.4. Milk Frothing (Steam Function)
The powerful steam wand allows you to create smooth, silky milk froth for lattes and cappuccinos.
- Ensure the machine is preheated for espresso.
- Press the 'Steam' button on the touch display. Wait for the button to stop blinking, indicating the steam function is ready.
- Tip: Before frothing, vent the steam for 2-3 seconds into an empty cup to release any condensed water and ensure dry steam. Turn the steam knob anti-clockwise to open, then close it.
- Fill a stainless steel frothing pitcher with cold milk (dairy or non-dairy) to just below the spout.
- Submerge the steam wand tip just below the surface of the milk.
- Slowly turn the steam knob anti-clockwise to release steam.
- Lower the pitcher slightly to introduce air, creating foam. Once desired foam is achieved, submerge the wand deeper to heat the milk.
- Once the milk reaches the desired temperature (around 140-150°F / 60-65°C), turn the steam knob clockwise to close it.
- Immediately wipe the steam wand with a damp cloth to prevent milk residue from drying.
