Powering On and Heating Up:

• Ensure the machine is properly connected to water and power.
• Turn the main power switch to the 'ON' position.

4. Start Brewing: Press the corresponding button to start the brewing process. The machine will automatically stop when the programmed volume is dispensed.
5. Remove Portafilter: After brewing, carefully remove the portafilter and discard the spent coffee grounds.

Steaming Milk:

• Purge the steam wand briefly to remove any condensed water.
• Immerse the steam wand tip into a pitcher of cold milk.
• Open the steam valve slowly to begin steaming.
• Once the desired temperature and texture are achieved, close the steam valve.
• Immediately wipe the steam wand clean with a damp cloth and purge again to prevent milk residue buildup.
