2.2 Preparing Espresso

1. Grind Size: For optimal espresso extraction, use a fine grind. The texture should be slightly finer than table salt, powdery but with a bit of roughness to the touch. Avoid grinds that are too coarse (like rock salt or sand) or too fine (like flour).
2. Dosing: For the 1-cup filter basket, use 13-14g of ground coffee. For the 2-cup filter basket, use 19-20g of ground coffee. The included dosing ring can assist in minimizing mess during this step.
3. Tamping: Use the tamper to press the coffee grounds firmly and evenly. After tamping, the surface of the coffee should be approximately 1-2mm below the filter rim. A tamping force of around 13 kgf is recommended for optimal results.
4. Insert Portafilter: Attach the filled and tamped portafilter to the brew head. Turn it firmly to the right until it is securely locked in place.
5. Extraction: Place your espresso cup(s) on the drip tray. The machine offers both manual and automatic pour options. The visible pressure gauge and temperature display provide precise readings, allowing you to monitor the extraction process. Aim for the 'Optimal Extraction' range on the pressure gauge for the best results.

2.3 Pre-infusion Function

The machine utilizes a pre-infusion technology to ensure smoother water flow and preserve the coffee's purity, leading to a more flavorful extraction.

2.4 Milk Frothing

The powerful steam wand allows you to create delicate, rich milk foam for lattes and cappuccinos. Use the included 350ml milk frothing pitcher for best results. Turn the steam control knob to activate the steam wand and immerse it into the milk. Once desired foam is achieved, turn off the steam and clean the wand immediately.

3. Maintenance

3.1 Cleaning the Drip Tray

The drip tray is removable for easy cleaning. Regularly empty and wash the drip tray with warm, soapy water to prevent overflow and maintain hygiene.

3.2 General Cleaning

Wipe down the exterior of the machine with a soft, damp cloth. Do not use abrasive cleaners or scouring pads. The portafilter and filter baskets should be cleaned after each use. The machine is not dishwasher safe.

4. Troubleshooting

4.1 Insufficient Pressure During Extraction

If you experience insufficient pressure, resulting in a less than satisfactory espresso, consider the following:

• Grind Size: A grind that is too coarse will allow water to pass through too quickly, leading to low pressure. Adjust to a finer grind.
• Coffee Grounds Quantity: Too few coffee grounds in the filter basket can also cause insufficient pressure. Ensure you are using the recommended 13-14g for a single shot or 19-20g for a double shot.
• Tamping: Insufficient tamping of the coffee grounds will result in uneven water flow and low pressure. Tamp firmly and evenly.

4.2 Automatic Pressure Relief (OPV)

The espresso maker has a built-in Over Pressure Valve (OPV) that automatically opens if the pressure becomes too high. This mechanism releases excess pressure to maintain coffee taste and quality, and prevents damage to the boiler from over-pressurization.
