6. Operating Instructions
6.1 Making Espresso
- Pre-heat: Turn on the machine and allow it to heat up (lights stop flashing). Place your cup on the cup warmer.
- Prepare Portafilter: Insert the desired filter basket (single or double) into the portafilter.
- Add Coffee: Fill the filter basket with finely ground espresso coffee. Use the measuring scoop for consistent dosing.
- Tamp Coffee: Use the tamper to press the coffee grounds firmly and evenly. Wipe any excess grounds from the rim.
- Insert Portafilter: Attach the portafilter to the brewing head by aligning it and turning it firmly to the right until secure.
- Brew Espresso: Place your pre-heated cup(s) under the portafilter spouts. Press the single or double espresso button. The machine will automatically stop when the programmed volume is dispensed.

6.2 Frothing Milk
- Prepare Milk: Fill a stainless steel milk pitcher with cold milk (dairy or non-dairy) to just below the spout.
- Activate Steam: Press the steam button on the control panel. Wait for the steam light to illuminate steadily.
- Purge Steam Wand: Briefly open the steam knob to release any condensed water, then close it.
- Froth Milk: Immerse the steam wand tip just below the surface of the milk. Open the steam knob. Move the pitcher up and down to create foam. Once desired texture and temperature are reached, close the steam knob.
- Clean Wand: Immediately wipe the steam wand with a damp cloth to prevent milk residue from drying. Briefly open the steam knob again to clear any internal milk.

7. Maintenance and Cleaning
Regular cleaning ensures optimal performance and longevity of your appliances.
7.1 Espresso Machine Cleaning
- Daily:
- Empty and rinse the drip tray and water tank.
- Wipe the steam wand immediately after each use.
- Clean the portafilter and filter baskets.
- Weekly:
- Wipe down the exterior of the machine with a damp cloth.
- Clean the shower screen (where water dispenses into the portafilter) with a brush.
- Descaling: The machine will indicate when descaling is required (refer to the machine's specific indicator lights). Use a De'Longhi descaling solution and follow the instructions provided with the descaler. Descaling removes mineral buildup and is crucial for machine performance.
7.2 Knock Box Cleaning
- Empty coffee grounds regularly.
- The stainless steel container and removable bar are dishwasher safe. Alternatively, wash with warm soapy water and rinse thoroughly.
- Ensure the knock box is dry before next use.
8. Troubleshooting
Refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leaks from the water tank. | Water tank not inserted correctly. | Ensure the water tank is positioned properly and fits tightly from the bottom. |
| On/Off button does not respond. | Auto-off function activated (9 minutes of inactivity). | Press the On/Off button firmly until you feel a click, or press any button on the control panel to reactivate. |
| Both coffee buttons are flashing after frothing. | Machine temperature is too high for brewing espresso. | Turn the steam dial to the ON position to release hot water from the steam wand. When water stops, turn the dial to 'O'. The machine will cool down and be ready to brew. |
| Steam wand is clogged. | Milk residue has dried inside the nozzle. | Clean the nozzle immediately after each use. Push the button for steam before turning the steam knob to avoid clogging. Use a pin to clear the hole if clogged. |
| Espresso flows too slowly or not at all. | Coffee ground too fine, tamped too hard, or machine needs descaling. | Adjust grind size, tamp less firmly, or perform a descaling cycle. |
