- Pre-heat: Turn on the machine and allow it to pre-heat until the indicator light is solid, signaling it's ready for brewing.
- Prepare Coffee Grounds:
- Select the appropriate filter basket (one-cup or two-cup) and place it in the portafilter.
- Add finely ground espresso coffee to the filter basket.
- Use the tamper to press the coffee grounds firmly and evenly. Ensure the surface is level.
- Attach Portafilter: Insert the portafilter into the group head on the machine and twist it firmly to the right until it locks into place.
- Brew Espresso: Place your espresso cup(s) on the drip tray under the portafilter. Press the desired brewing button (single or double shot). The machine will automatically dispense the espresso.

5.2 Milk Frothing
The powerful steam wand allows you to create creamy milk foam for lattes and cappuccinos.
- Prepare Milk: Fill a stainless steel frothing pitcher with cold milk (whole milk is recommended for best results) to just below the spout.
- Activate Steam: Turn the steam control knob to activate the steam function. Wait for the steam indicator light to illuminate steadily, indicating the machine is ready to produce steam.
- Froth Milk:
- Submerge the tip of the steam wand just below the surface of the milk.
- Open the steam valve fully.
- Angle the pitcher to create a swirling motion, incorporating air into the milk to create foam.
- Once the desired texture and temperature are reached, close the steam valve and remove the pitcher.
- Clean Steam Wand: Immediately wipe the steam wand with a damp cloth to prevent milk residue from drying. Briefly open the steam valve again to clear any milk from inside the wand.

| Problem | Possible Cause | Solution |
|---|---|---|
