3. Operating Instructions
The De'Longhi BCO431.S offers two primary brewing methods: espresso and drip coffee, controlled via a digital interface.
3.1 Brewing Espresso
- Prepare the Portafilter: Insert the desired filter basket (for ground coffee or ESE pods) into the espresso portafilter.
- Add Coffee: If using ground coffee, fill the filter basket with finely ground espresso coffee. Tamp firmly. If using an ESE pod, place it correctly in the designated filter.
- Attach Portafilter: Securely attach the portafilter to the espresso group head on the machine.
- Place Cup: Position an espresso cup under the portafilter spouts.
- Start Brewing: Select the espresso function on the digital interface and press the brew button. The machine will deliver espresso at 15 bar pressure, producing a rich aroma and hazelnut-colored crema.
3.2 Frothing Milk (Manual Cappuccino System)
- Prepare Milk: Fill a pitcher with cold milk.
- Activate Steam: Turn the steam knob to activate the steam wand. Wait for the steam indicator light to illuminate, indicating optimal temperature.
- Froth Milk: Immerse the steam wand into the milk, just below the surface. Open the steam valve to release steam. Move the pitcher up and down to create foam with the desired density.
- Clean Wand: After frothing, close the steam valve and wipe the steam wand immediately with a damp cloth to prevent milk residue buildup.
3.3 Brewing Drip Coffee
- Prepare Filter: Open the drip coffee filter basket and insert a paper filter (if required by your model) or ensure the permanent filter is clean.
- Add Coffee Grounds: Add the desired amount of medium-ground coffee to the filter basket.
- Fill Water Tank: Ensure the water tank is filled with fresh, cold water according to the number of cups desired (up to 10 cups capacity).
- Place Carafe: Position the glass carafe on the warming plate.
- Start Brewing: Select the drip coffee function on the digital interface and press the brew button. The machine will begin brewing.
