4.1 Brewing Espresso

1. Ensure the water tank is filled with fresh water.
2. Add medium-sized coffee grounds to the filter basket. This 3.5 bar machine does not support very fine grinds.
3. Insert the filter holder into the machine. Rotate the filter holder counter-clockwise until the handle is in the 'lock' position. Ensure it is tightened to prevent steam leakage.
4. Place the glass pot on the drip tray.
5. Turn the single switch knob to the 'Brew' position. The machine will begin brewing espresso into the glass pot.
6. Once the desired amount of espresso is brewed (up to 4 cups or 240 ml), turn the switch knob to the 'OFF' position.

4.2 Frothing Milk for Lattes and Cappuccinos

1. Fill a pitcher with cold milk (dairy or non-dairy).
2. Turn the switch knob to the 'Steam' position and wait for the steam indicator light to illuminate, indicating the machine is ready.
3. Submerge the steam wand into the milk, just below the surface.
4. Turn the steam control knob to release steam. Move the pitcher up and down to create rich, creamy foam.
5. Once desired foam consistency is achieved, turn off the steam control knob and then the main switch knob to 'OFF'.
6. Immediately wipe the steam wand with a damp cloth to prevent milk residue from drying.

5. Maintenance and Cleaning

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

• Drip Tray and Nozzle: The drip tray and nozzle are removable for easy cleaning. Empty and clean the drip tray after each use.
• Filter Holder and Basket: After each use, remove the filter holder and discard used coffee grounds. Rinse the filter holder and basket under running water.
• Steam Wand: Immediately after frothing milk, wipe the steam wand with a damp cloth to prevent milk residue from hardening. If clogged, use a small pin to clear the opening.
• Exterior: Wipe the exterior of the machine with a soft, damp cloth. Do not use abrasive cleaners or scouring pads.
• Descaling: Depending on water hardness, descale the machine every 2-3 months using a commercial descaling solution or a mixture of white vinegar and water. Follow the descaling product's instructions.
