3. Operating Instructions
3.1 Preparing Your Coffee
- Fill the filter basket with medium ground coffee. Do not use fine ground coffee (suggested >0.5mm) as it can cause clogging or machine malfunction.
- Use the tamper end of the coffee scoop to gently press the coffee grounds. Do not over-pack the coffee grounds, as this can lead to excessive pressure buildup.
- Clean any excess coffee grounds from the edge of the filter basket.
- Insert the filter holder into the machine and turn it clockwise until it aligns with the "LOCK" symbol. Ensure it is securely tightened to prevent leaks.

3.2 Brewing Espresso
- Place the Tritan carafe on the drip tray directly under the filter holder.
- Turn the control knob to the "Brew" position. The indicator light will illuminate, signifying the machine is heating and brewing.
- Coffee will begin to dispense into the carafe. The machine can make 1-4 cups (240 ml) of coffee in approximately 2-3 minutes.
- Once the desired amount of coffee is brewed, turn the control knob to "Off".

3.3 Frothing Milk for Cappuccino/Latte
For best results, use whole milk to create dense milk froth.
- Fill a pitcher with cold whole milk.
- Turn the control knob to the "Steam" position. The indicator light will illuminate, indicating the machine is preheating for steam.
- Once the steam is ready (the light may change or a steady steam sound is heard), immerse the steam wand into the milk, about 1 inch below the surface.
- Move the pitcher slowly up and down to create froth. Continue for about 30 seconds or until desired froth consistency is achieved.
- Turn the control knob to "Off" and remove the pitcher.

4.2 Descaling
Over time, mineral deposits can build up inside 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 manufacturer's instructions (or use a mixture of white vinegar and water).
- Pour the solution into the water reservoir.
- Place an empty carafe on the drip tray.
- Run the machine through a brewing cycle without coffee.
- After the cycle, turn the knob to "Steam" and let some solution pass through the steam wand to clean it.
- Repeat the process with clean water 2-3 times to rinse out any descaling solution residue.
