5. Operating Instructions

5.1 Brewing Espresso (Ground Coffee)

1. Ensure the machine is plugged in and the water tank is filled. Turn on the machine and wait for it to heat up (indicator light solid).
2. Insert the double filter basket into the portafilter.
3. Add finely ground espresso coffee to the filter basket. Use the included coffee spoon to measure (approximately 7-10g per shot).
4. Use the tamper end of the coffee spoon to gently press the ground coffee evenly. Do not over-tamp.
5. Attach the portafilter to the group head by aligning it and twisting firmly to the right until secure.
6. Place one or two espresso cups under the portafilter spouts.
7. Press the coffee brewing button. The machine will start extracting espresso. Monitor the built-in pressure gauge for optimal extraction (typically in the middle of the green zone).
8. Once the desired amount of espresso is brewed (usually 25-30ml per shot), press the coffee brewing button again to stop the flow.
9. Carefully remove the portafilter (it will be hot) and discard the used coffee grounds. Clean the portafilter and filter basket immediately.

5.2 Brewing Espresso (E.S.E. Pods)

1. Follow step 1 from "Brewing Espresso (Ground Coffee)".
2. Insert the coffee pod filter basket into the portafilter.
3. Place one E.S.E. (Easy Serving Espresso) pod into the filter basket. Ensure it lies flat.
4. Attach the portafilter to the group head and secure it.
5. Place one espresso cup under the portafilter spout.
6. Press the coffee brewing button to start extraction.
7. Press the button again to stop the flow when desired volume is reached.

5.3 Frothing Milk

1. Ensure the machine is on and heated.
2. Fill a stainless steel frothing pitcher with cold milk (dairy or non-dairy) to just below the spout.
3. Turn the steam knob to the steam position. Wait for the steam indicator light to illuminate, indicating the machine has reached frothing temperature.
4. Purge the steam wand: Briefly open the steam knob to release any condensed water, then close it.
5. Insert the steam wand tip just below the surface of the milk in the pitcher.
6. Open the steam knob fully. Lower the pitcher slightly to introduce air for frothing, then raise it to heat the milk. Move the pitcher in a circular motion.
7. Once the milk reaches the desired temperature and texture (approximately 60-70°C or 140-160°F), close the steam knob.
8. Immediately wipe the steam wand with a damp cloth to prevent milk residue from drying.

6. Maintenance and Cleaning

Regular cleaning ensures optimal performance and extends the lifespan of your espresso machine.

6.1 Daily Cleaning

• Portafilter and Filter Baskets: After each use, remove the portafilter, discard grounds/pod, and rinse the portafilter and filter basket under running water. Use a brush to remove any coffee residue.
• Steam Wand: Immediately after frothing milk, wipe the steam wand with a damp cloth. Purge steam briefly to clear any milk from the nozzle. If clogged, use a small pin to clear the hole.
• Drip Tray: Empty and rinse the drip tray daily or when the indicator floats up.
• Water Tank: Empty any remaining water from the tank and rinse it daily. Refill with fresh water before each use.
• Exterior: Wipe the exterior of the machine with a soft, damp cloth. Do not use abrasive cleaners or scourers.

6.2 Descaling

Depending on water hardness and frequency of use, descaling should be performed every 2-3 months. Use a commercial descaling solution specifically designed for espresso machines, following the manufacturer's instructions. Never use vinegar, as it can damage internal components.

1. Prepare the descaling solution according to the product instructions and pour it into the water tank.
2. Place a large container under the coffee outlet and steam wand.
3. Run the descaling solution through the coffee outlet until half the tank is empty.
4. Run the remaining solution through the steam wand.
5. Rinse the water tank thoroughly and fill it with fresh water.
6. Perform at least two full rinse cycles with fresh water through both the coffee outlet and steam wand to remove any descaling solution residue.
