Short or long cup
Optional accessories: flat and arched stands may not be included. The long cup can be used as the extraction support. Do not extract directly into the short cup without a stand.
Quick start
Prepare the machine fully before starting an extraction.
Disassemble the lower section
Unscrew the cup, pressure chamber and relevant coffee adapter from the main body.
Load your coffee
Choose either the capsule adapter or portafilter basket for ground coffee, following the instructions below.
Assemble the pressure chamber
Fit the loaded adapter into the pressure chamber and secure it firmly to the main body.
Position the cup
Place the main body above the long cup or use an optional stand with a suitable cup.
Add water and brew
Add hot or room-temperature water, replace the lid securely and select the correct extraction method.
Prepare and brew
Use one brewing system at a time.
Coffee capsule
- Use a Nespresso-compatible capsule or one of the same size.
- Press the capsule firmly into the capsule adapter.
- Place the capsule adapter upside down inside the pressure chamber.
- Check that it is seated correctly before tightening.
Ground coffee
- Insert the portafilter basket into the pressure chamber.
- Add one scoop, approximately 8 g, of coffee.
- Use coffee particles larger than 0.45 mm; overly fine coffee may clog the machine.
- Press the coffee flat with the scoop and fit the portafilter lid tightly.
Using hot water
Add water at 92°C or above. Hold the power button for 1.5 seconds to unlock, then hold it for 2 seconds to start extraction. The green light flashes downward as extraction begins.
Using room-temperature water
Press the power button briefly to start heating and extraction. The red indicator flashes upward while heating. At extraction temperature, it turns green and flashes downward while extracting.
Stop at any time: press the power button during heating or extraction.
Water quantities
- 35 ml: approximately 25 ml ristretto.
- 50 ml: approximately 40 ml espresso and the recommended quantity for best results.
- 65 ml maximum: approximately 55 ml coffee.
Estimated output per full charge
- 35 ml room-temperature water: approximately 5–7 heated extractions.
- 50 ml room-temperature water: approximately 4–5 heated extractions.
- 65 ml room-temperature water: approximately 3–4 heated extractions.
- Using water at 92°C: more than 400 extractions may be possible because heating is not required.
Always use purified water.

Yellow lights during extraction: stop immediately, unscrew and readjust the pressure chamber. Too much coffee, an incorrectly sized or deformed capsule, or an obstruction may trigger overload protection. Repeated forced extraction may damage the machine.
Troubleshooting
Match the indicator pattern to the likely cause before trying again.
| Issue | Indicator | Possible cause | Solution |
|---|---|---|---|
| No heating | One red light flashing | Low battery | Charge immediately. |
| No heating | Four yellow lights flashing | Dry-boil protection | Check that the water tank contains water. |
| No heating | Four red lights steady/on-off | Component malfunction | Contact after-sales service. |
| No extraction | One red light flashing | Low battery | Charge immediately. |
| No extraction | Four yellow lights flashing | Extraction overload | Use coarser coffee or reduce tamping pressure, then readjust and extract again. |
| No charging response | No indicators | Battery overheating | Allow the machine to cool before charging. |
| No charging response | No indicators | Incompatible adapter | Replace with a compatible 18 W+ adapter supporting 9 V / 2 A. |
| No response to long press | No indicators | Battery overheating | Allow the machine to cool before use. |
| No response to long press | No indicators | Circuit-board damage | Contact after-sales service. |
Heat protection: continuous heating may raise the battery temperature and trigger automatic shutdown. Allow the machine to cool. Pause for 30 minutes between every three consecutive heating cycles.
Leaks, poor crema or brewing failure
Ground coffee
- Use approximately 8 g and do not overfill.
- Tamp evenly before fitting the lid.
- Verify that the portafilter basket is installed correctly.
- Confirm that the pressure chamber is securely fastened.
Capsules
- Press the capsule firmly into the adapter.
- Check that the adapter is seated correctly in the pressure chamber.
- Screw the pressure chamber tightly onto the main body.
Care and safety
- Fully charge the battery before long-term storage to help prevent damage.
- Clean only with a slightly damp cloth. Never rinse the unit directly or submerge it in water.
- Never open the lid during extraction; hot water and pressure may cause burns.
- Wait a few minutes after extraction before removing used coffee grounds or capsules.
- Do not tilt the machine during operation.
- The capsule compartment contains blades. Take care during cleaning to avoid cuts.
- If charging fails, use a compatible charger rated at least 18 W and supporting 9 V / 2 A.
- If overheating protection activates, allow the machine to cool before charging or using it again.
