5. Setup
5.1 Initial Cleaning
- Unpack all components from the box.
- Disassemble the machine by unscrewing the pump from the top, removing the filter basket, and separating the cup from the main body.
- Wash all removable parts (water reservoir, filter basket, cup, scoop, brush) with warm soapy water. Rinse thoroughly and dry completely.
- Wipe the exterior of the main unit with a damp cloth.
5.2 Assembly
- Ensure the stand legs are unfolded and stable.
- Place the main unit onto the stand.
- Ensure the filter basket is clean and ready for coffee grounds.
6. Operation
Follow these steps to prepare espresso with your STARESSO PLUS SP300:
- Prepare Coffee Grounds: Use finely ground coffee. For optimal results, a grind suitable for espresso machines is recommended. The pressurized filter basket is more forgiving with grind size.
- Add Coffee Grounds: Unscrew the bottom part of the main unit to access the filter basket. Fill the filter basket with ground coffee. The machine can hold up to 24g of coffee powder.
- Tamp Coffee: For the included pressurized filter, simple tamping is sufficient. Ensure the coffee bed is level.
- Reassemble Filter Basket: Screw the filter basket back onto the main unit securely.
- Add Hot Water: Unscrew the pump from the top. Pour hot water (ideally 205-210°F or 96-98°C) into the water reservoir. Do not exceed the MAX fill line (180ml).
- Secure Pump: Screw the pump mechanism back onto the top of the main unit tightly.
- Position Cup: Place your espresso cup or the included cup beneath the machine's nozzle.
- Extract Espresso: Begin pressing the pump handle down at a constant, steady speed. You will feel resistance as pressure builds. Continue pumping until espresso flows into your cup. The internal extraction pressure can reach 15-20 bar, ensuring a rich extraction with visible crema.
- Serve: Once the desired amount of espresso is extracted (typically 60ml for a single shot), release the pump. Enjoy your fresh espresso.

8. Troubleshooting
If you encounter issues with your STARESSO PLUS SP300, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No espresso or very slow flow | Coffee grounds too fine or over-tamped; insufficient hot water; clogged filter. | Use a slightly coarser grind; reduce tamping pressure; ensure adequate hot water; clean filter basket thoroughly. |
| Weak or watery espresso | Coffee grounds too coarse; insufficient coffee quantity; water not hot enough. | Use a finer grind; increase coffee quantity (up to 24g); ensure water is near boiling (205-210°F). |
| No crema or thin crema | Stale coffee; incorrect grind size; insufficient pressure during extraction. | Use fresh coffee beans; adjust grind size; ensure consistent and firm pumping action. |
| Leaking from connections | Components not screwed on tightly; damaged O-rings/seals. | Ensure all parts are securely tightened; inspect O-rings for wear and replace if necessary. |
