Before first use, wash the glass carafe, portafilter, and stainless steel filter in warm, soapy water. Rinse thoroughly and dry. Wipe the exterior of the machine with a damp cloth.
4.3 Filling the Water Tank
Open the water tank lid and fill the tank with fresh, cold water up to the MAX level indicated. Do not overfill.

To prime the pump and remove any air from the system:
- Ensure the water tank is filled.
- Place the glass carafe on the drip tray.
- Plug the machine into a suitable power outlet.

5. Operating Instructions
5.1 Making Espresso
- Preheating: Ensure the water tank is filled. Turn the control knob to the preheat position (usually indicated by a coffee cup symbol or a heating element symbol). Wait for the indicator light to show the machine is ready (typically 3-5 minutes).
- Add Ground Coffee: Place the stainless steel filter into the portafilter. Add desired amount of finely ground espresso coffee (approximately 7g per shot). Tamp the coffee lightly and evenly.
- Attach Portafilter: Align the portafilter with the group head on the machine and twist it firmly to the right until it is securely locked.
- Brewing: Place the glass carafe under the portafilter. Turn the control knob to the coffee brewing position. Coffee will begin to flow.
- Stop Brewing: Once the desired amount of espresso is brewed (e.g., 30-60ml per shot), turn the control knob to the OFF position.
- Serve: Carefully remove the carafe and serve the espresso.
5.2 Making Cappuccino (Using Steam Wand)
To make cappuccino, you will first brew espresso as described above, then froth milk using the steam wand.
- Prepare Espresso: Brew your espresso into a heat-resistant cup.
- Prepare Milk: Fill a small pitcher with cold milk (dairy or non-dairy) to about one-third full.
- Activate Steam: Turn the control knob to the steam position (usually indicated by a steam cloud symbol). Wait for the indicator light to show the machine is ready for steaming.
- Froth Milk: Submerge the tip of the steam wand just below the surface of the milk. Open the steam valve (if applicable, or turn the knob further to steam). Move the pitcher up and down gently to create foam. Continue until the milk reaches the desired temperature and consistency.
- Clean Steam Wand: Immediately after frothing, turn off the steam and wipe the steam wand with a damp cloth to prevent milk residue from drying.
- Combine: Pour the frothed milk over your prepared espresso.
6. Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the life of your espresso machine.
6.1 Daily Cleaning
- Portafilter and Filter: After each use, remove the portafilter, discard used coffee grounds, and rinse the portafilter and filter under running water.
- Glass Carafe: Wash the glass carafe after each use.
- Drip Tray: Empty and clean the drip tray regularly to prevent overflow.
- Exterior: Wipe the exterior of the machine with a soft, damp cloth. Do not use abrasive cleaners or scourers.
6.2 Descaling
Over time, mineral deposits (limescale) can build up in the machine, affecting performance. Descale your machine every 2-3 months, or more frequently if you have hard water.
- Prepare a descaling solution according to the descaler product instructions (or use a mixture of white vinegar and water).
- Fill the water tank with the descaling solution.
- Place the glass carafe under the portafilter.
- Run the machine through a brewing cycle until half of the solution has passed through.
- Turn off the machine and let it sit for 15-20 minutes.
- Run the remaining solution through the machine.
- Rinse the water tank and fill it with fresh water. Run several cycles with fresh water to thoroughly rinse out any descaling solution.
