5. Operating Instructions

This section guides you through preparing espresso and frothing milk.

5.1 Making Espresso

1. Preheat: Ensure the machine is powered on and preheated (indicator light solid). Place your espresso cup on the cup warming plate.
2. Prepare Portafilter: Insert the filter basket into the portafilter. Add finely ground espresso coffee to the filter basket. For a single shot, use one level scoop; for a double shot, use two.
3. Tamp Coffee: Use the tamper to press the ground coffee firmly and evenly. Wipe any excess coffee from the rim of the portafilter.
4. Attach Portafilter: Align the portafilter with the group head and twist it firmly to the right until it is securely locked.
5. Brew Espresso: Place one or two preheated cups under the portafilter spouts. Press the espresso brewing button (single or double shot, if available). The machine will dispense espresso. Press the button again to stop brewing if it's not automatic.
6. Remove Portafilter: Once brewing is complete, carefully remove the portafilter by twisting it to the left. Discard the used coffee grounds.

5.2 Frothing Milk (Using Steam Wand)

1. Prepare Milk: Fill a stainless steel frothing pitcher with cold milk (dairy or non-dairy) to just below the spout.
2. Activate Steam: Press the steam button on the control panel. Wait for the steam indicator light to illuminate, indicating the machine has reached steaming temperature.
3. Purge Steam Wand: Briefly open the steam knob to release any condensed water from the wand into the drip tray. Close the knob.
4. Froth Milk: Immerse the tip of the steam wand just below the surface of the milk. Open the steam knob slowly. Move the pitcher up and down to create foam. Once desired foam and temperature are reached, close the steam knob.
5. Clean Steam Wand: Immediately wipe the steam wand with a damp cloth to remove any milk residue. Briefly open the steam knob again to clear any milk from inside the wand.
