5. Operating Instructions
5.1 Powering On
Press the ON/OFF button on the touchscreen. The machine will preheat, and the indicators will stop flashing when ready.
5.2 Making Espresso
- Prepare the Portafilter: Insert the desired filter basket (single or double) into the portafilter. For ground coffee, fill the basket with finely ground espresso coffee. Tamp the coffee evenly with a tamper. For pods, place the pod in the appropriate basket.
- Attach Portafilter: Align the portafilter with the group head and twist firmly to the right until it is securely locked.
- Place Cup: Position your pre-warmed espresso cup(s) on the drip tray directly under the portafilter spouts.
- Select Brew: On the touchscreen, select Espresso for a single shot or 2 X Espresso for a double shot. The machine will automatically brew and stop.
- Remove Portafilter: Once brewing is complete, carefully remove the portafilter by twisting it to the left. Dispose of the used coffee grounds or pod.
5.3 Making Americano
- Brew a single or double espresso as described in section 5.2.
- Once the espresso is brewed, select the Americano option on the touchscreen. The machine will dispense hot water into your cup, diluting the espresso to an Americano.
5.4 Steaming Milk (for Cappuccino & Latte)
- Prepare Milk: Fill a stainless steel frothing pitcher with cold milk (dairy or non-dairy) to just below the spout.
- Activate Steam: Press the Steam button on the touchscreen. The machine will heat up to steam temperature.
- Purge Steam Wand: Once the steam indicator is solid, position the steam wand over the drip tray and briefly open the steam control knob to release any condensed water. Close the knob.
- Froth Milk: Immerse the tip of the steam wand just below the surface of the milk. Open the steam control knob. For cappuccino, keep the tip near the surface to create foam. For latte, immerse it deeper for less foam and more steamed milk.
- Monitor Temperature: Continue steaming until the milk reaches the desired temperature (around 60-70°C or when the pitcher is too hot to touch comfortably).
- Stop Steaming: Close the steam control knob, then remove the pitcher.
- 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.
- Combine steamed milk with your freshly brewed espresso.
5.5 Espresso Cool Function
The Espresso Cool function is designed to quickly cool the machine down after steaming milk, bringing it back to optimal brewing temperature for espresso. After steaming, press this button to initiate the cooling process. The machine will dispense a small amount of water to cool down.
6. Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the life of your espresso machine.
6.1 Daily Cleaning
- Drip Tray: Empty and rinse the drip tray and grid after each use or when the indicator floats up.
- Portafilter and Filter Baskets: Remove used coffee grounds. Rinse the portafilter and filter basket under hot water.
- Steam Wand: Always wipe the steam wand immediately after use with a damp cloth. Purge steam briefly to clear any internal residue.
- Exterior: Wipe the machine's exterior with a soft, damp cloth. Do not use abrasive cleaners or scouring pads.
6.2 Water Tank Cleaning
Clean the water tank weekly with mild detergent and rinse thoroughly. Ensure no soap residue remains.
6.3 Descaling
Descaling is crucial to remove mineral buildup and maintain machine performance. The frequency depends on water hardness and usage, typically every 2-3 months.
- Fill the water tank with a descaling solution according to the descaler manufacturer's instructions, or use a mixture of white vinegar and water (1:1 ratio).
- Place a large container under the portafilter and steam wand.
- Turn on the machine. Once heated, run several cycles of espresso (without coffee) until half of the solution is used.
- Open the steam knob and let the remaining solution run through the steam wand until the tank is empty.
- Rinse the water tank thoroughly and fill with fresh water.
- Repeat steps 3-5 with fresh water to rinse out any descaling solution residue.
