- Positioning: Place the espresso maker on a stable, flat, heat-resistant surface near a power outlet. Ensure adequate ventilation around the machine.
- Fill Water Tank: Remove the water tank from the back of the machine. Fill it with fresh, cold water up to the MAX line. Replace the tank securely.

5. Operating Instructions
Preparing Espresso

6. Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the life of your espresso maker.
Daily Cleaning
- Portafilter and Filters: After each use, remove the portafilter and discard coffee grounds. Rinse the portafilter and filter under running water. Use a brush to remove any residue.
- Milk Tank and Frothing Nozzle: Immediately after preparing milk-based drinks, remove the milk tank. Disassemble the frothing nozzle components and wash all parts with warm, soapy water. Rinse thoroughly. Run a quick cleaning cycle by pressing the 'Clean' button (if available) or by running hot water through the frothing system without milk.
- Drip Tray: Empty and clean the drip tray regularly.
- Exterior: Wipe the exterior of the machine with a soft, damp cloth. Do not use abrasive cleaners or scouring pads.
Descaling
Over time, mineral deposits (limescale) can build up in the machine, affecting performance. Descale your machine every 2-3 months, or more frequently if you have hard water.
- Prepare a descaling solution according to the descaler manufacturer's instructions, or use a mixture of white vinegar and water (1 part vinegar to 2 parts water).
- Fill the water tank with the descaling solution.
- Place a large container under the coffee spout and another under the milk frothing nozzle.
- Run several brewing cycles (Espresso button) until half of the solution has passed through.
- Run several milk frothing cycles (Cappuccino/Latte button) until the remaining solution has passed through.
- Turn off the machine and let it sit for 15-20 minutes.
- Empty and rinse the water tank. Fill it with fresh water.
- Run several full water tanks through the machine (both brewing and frothing cycles) to thoroughly rinse out any descaling solution.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No coffee dispenses | Water tank empty; machine not primed; clogged filter/portafilter. | Fill water tank; perform priming cycle; clean portafilter and filter. |
| Coffee is too weak/strong | Incorrect coffee grind; incorrect coffee amount; water temperature issue. | Adjust grind size (finer for stronger, coarser for weaker); adjust coffee amount; ensure machine is fully heated. |
| Milk not frothing properly | Milk tank empty; milk too warm; frothing nozzle clogged; milk type. | Fill milk tank with cold milk; clean frothing nozzle thoroughly; try different milk types (e.g., whole milk for best froth). |
| Machine leaks water | Water tank not seated correctly; drip tray full; seal issues. | Ensure water tank is firmly in place; empty drip tray; contact customer support if seals appear damaged. |
| Machine not turning on | No power; faulty power button. | Check power outlet and cord connection; contact customer support. |
