Setup
- Unpacking: Carefully remove all packaging materials and ensure all parts are present.
- Initial Cleaning: Wash the water tank, portafilter, filter basket, and drip tray with warm, soapy water. Rinse thoroughly and dry. Wipe the exterior of the machine with a damp cloth.
- Fill Water Tank: Fill the removable water tank with fresh, cold water up to the MAX level indicator. Place the tank back securely.
- First Use / Priming: Before making coffee, run a cycle with just water to prime the system and clean internal components. Ensure the machine is plugged in, turn it on, and let it heat up. Place a cup under the portafilter (without coffee) and press the brew button to dispense hot water. Repeat this process for the steam wand as well.
Operating Instructions
Making Espresso
- Preheat: Ensure the machine is turned on and has reached its operating temperature (indicator light will show).
- Prepare Coffee: Add ground coffee to the filter basket. For a single shot, use one scoop; for a double shot, use two. Tamp the coffee evenly with a tamper.
- Attach Portafilter: Insert the portafilter into the group head and turn it firmly to the right until it locks into place.
- Brew Espresso: Place your espresso cup(s) on the drip tray. Press the desired brew button (single or double shot). The machine will automatically dispense the correct amount of espresso.
- Remove Portafilter: Once brewing is complete, carefully remove the portafilter by turning it to the left. Discard the used coffee grounds.
Milk Frothing
- Prepare Milk: Fill a stainless steel frothing pitcher with cold milk (dairy or non-dairy) to just below the spout.
- Preheat Steam Wand: Turn the steam function on and allow the steam wand to heat up. Purge a small amount of steam into the drip tray to remove any condensed water.
- Froth Milk: Immerse the tip of the steam wand just below the surface of the milk. Open the steam valve slowly. Move the pitcher up and down to create foam. Once 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. Purge a small amount of steam again to clear any internal blockages.
Note: For optimal results when making milk-based drinks, brew your espresso first, then froth your milk. If frothing milk first, allow the machine to cool down slightly before brewing espresso to ensure proper extraction temperature.
Maintenance and Cleaning
Regular cleaning ensures the longevity and optimal performance of your espresso machine.
Daily Cleaning
- Portafilter and Filter Basket: After each use, remove and rinse the portafilter and filter basket under running water.
- Drip Tray: Empty and clean the drip tray and grid daily.
- Water Tank: Rinse the water tank daily and refill with fresh water.
- Steam Wand: As mentioned in the operating instructions, wipe and purge the steam wand immediately after each use.
- Exterior: Wipe the exterior of the machine with a soft, damp cloth. Do not use abrasive cleaners.
Descaling
Descaling is crucial to remove mineral buildup and maintain machine efficiency. The frequency depends on water hardness and usage, but generally every 2-3 months. Refer to a descaling solution's instructions for specific steps, or follow these general guidelines:
- Mix descaling solution with water according to product instructions and pour into the water tank.
- Place a large container under the group head and steam wand.
- Run several brewing cycles and steam cycles until the water tank is empty.
- Rinse the water tank thoroughly and refill with fresh water.
- Run several cycles with fresh water to flush out any remaining descaling solution.
