5. Operating Instructions

5.1 Making Espresso

1. Prepare the Machine: Ensure the water tank is filled and the machine is plugged in and powered on. Allow it to preheat until the indicator light is stable or the pressure gauge is in the optimal brewing zone.
2. Prepare the Portafilter: Insert the desired filter basket (single or double shot) into the portafilter. For ground coffee, fill the basket with finely ground espresso coffee. For ESE pods, place one pod into the appropriate basket.
3. Tamp the Coffee (for ground coffee): Use the tamper end of the measuring scoop 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 on the machine. Insert it and turn it firmly to the right until it is securely locked in place.
5. Place Cups: Position one or two espresso cups on the drip tray directly under the portafilter spouts.
6. Brew Espresso: Press the Espresso button. The machine will begin to extract coffee. Monitor the pressure gauge for optimal brewing pressure.
7. Stop Brewing: Press the Espresso button again to stop the flow once the desired amount of espresso is reached.
8. Remove Portafilter: Carefully turn the portafilter to the left to unlock and remove it. Be cautious as it will be hot.
9. Discard Coffee Grounds: Tap out the used coffee grounds (puck) from the filter basket. Rinse the portafilter and filter basket with water.

5.2 Steaming Milk for Cappuccino/Latte

1. Prepare the Machine: Ensure the water tank is filled. Press the Steam button to activate the steam function. Wait for the machine to reach steaming temperature (indicator light stable or pressure gauge in steam zone).
2. Prepare Milk: Fill a stainless steel frothing pitcher with cold milk (dairy or non-dairy) to just below the spout.
3. Purge Steam Wand: Position the steam wand over the drip tray and briefly open the steam knob to release any condensed water. Close the knob.
4. Steam Milk: Immerse the tip of the steam wand just below the surface of the milk. Open the steam knob fully.
5. Froth Milk: Hold the pitcher at an angle, moving it slightly up and down to create foam. For latte, immerse the wand deeper for less foam. For cappuccino, keep the tip closer to the surface for more foam.
6. Stop Steaming: Once the milk reaches the desired temperature and texture (around 60-70°C or 140-160°F), close the steam knob and remove the pitcher.
7. 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.

6. Maintenance and Cleaning

Regular cleaning and maintenance ensure optimal performance and longevity of your espresso machine.

6.1 Daily Cleaning

• Portafilter and Filter Baskets: After each use, remove and rinse the portafilter and filter basket under running water. Ensure all coffee grounds are removed.
• Drip Tray: Empty and clean the drip tray daily or when the indicator floats up. Wash with warm, soapy water and rinse thoroughly.
• Steam Wand: As described in Section 5.2, clean the steam wand immediately after each use to prevent milk residue buildup.
• Exterior: Wipe the exterior of the machine with a soft, damp cloth. Do not use abrasive cleaners or scourers.

6.2 Water Tank Cleaning

Clean the water tank weekly or as needed. Remove the tank, wash it with mild detergent and warm water, rinse thoroughly, and air dry before refilling.

6.3 Descaling

Mineral deposits from water can build up in the machine over time, affecting performance. Descale your machine every 2-3 months, or more frequently if you have hard water.

1. Use a commercial descaling solution designed for coffee machines, following the manufacturer's instructions. Alternatively, a solution of white vinegar and water (1:1 ratio) can be used.
2. Fill the water tank with the descaling solution.
3. Place a large container under the group head and steam wand.
4. Run several cycles of hot water through the group head and steam wand until the tank is empty.
5. Rinse the water tank thoroughly and refill with fresh water.
6. Run several cycles of fresh water through the machine to flush out any remaining descaling solution.
