Setup and First Use
Unpacking and Placement:
- Carefully remove all packaging materials and ensure all components are present.
- Place the coffee maker on a stable, flat, heat-resistant surface, away from water sources and heat.
- Ensure there is adequate space around the appliance for ventilation and operation.
Initial Cleaning:
- Wash the water tank, portafilter, filters, and measuring scoop with warm soapy water. Rinse thoroughly and dry.
- Wipe the exterior of the appliance with a damp cloth.
First Use (Priming the System):
- Fill the water tank with fresh, cold water up to the MAX level.
- Place an empty cup under the brewing head.
- Plug the appliance into a power outlet and turn it ON. The power indicator light will illuminate.
- Allow the machine to heat up until the temperature gauge indicates it's ready for brewing (usually in the optimal espresso range).
- Turn the function dial to the coffee brewing position and allow water to flow through the brewing head for approximately 30 seconds. This primes the pump and flushes the system.
- Turn the function dial back to the standby position.
- Repeat this process for the steam wand: place a cup under the steam wand, turn the dial to the steam position, and let steam release for a few seconds. Then turn it off.
- The machine is now ready for use.
Operating Instructions
Making Espresso:
- Ensure the water tank is filled with fresh water.
- Select the appropriate filter (single or double shot) and place it into the portafilter.
- Using the measuring scoop, add ground coffee to the filter. For a single shot, use one scoop (approx. 7g); for a double shot, use two scoops (approx. 14g).
- Lightly tamp the coffee grounds evenly. Do not over-tamp.
- Attach the portafilter to the brewing head by aligning it and twisting firmly to the right until secure.
- Place one or two espresso cups on the drip tray beneath the portafilter spouts.
- Turn the machine ON and wait for the temperature gauge to reach the optimal brewing range.
- Turn the function dial to the coffee brewing position. Espresso will begin to flow into the cups.
- Once the desired volume is reached (typically 25-30ml for a single shot, 50-60ml for a double shot), turn the function dial back to the standby position to stop brewing.
- Carefully remove the portafilter, discard the used coffee grounds, and rinse the portafilter and filter.

Frothing Milk for Cappuccino/Latte:
- After brewing espresso, ensure the machine is still ON and the temperature gauge is in the steam range.
- Fill a stainless steel frothing pitcher with cold milk (dairy or non-dairy) to about one-third full.
- Position the steam wand just below the surface of the milk.
- Turn the function dial to the steam position. Steam will begin to release.
- Lower the pitcher slightly to introduce air into the milk, creating foam. Move the pitcher up and down gently.
- Once the milk has doubled in volume and reached the desired temperature (around 60-70°C), turn the function dial back to the standby position.
- Immediately wipe the steam wand with a damp cloth to prevent milk residue from drying.
- Pour the frothed milk over your freshly brewed espresso to create a cappuccino or latte.

Cleaning and Maintenance
Regular cleaning ensures optimal performance and extends the lifespan of your coffee maker.
Daily Cleaning:
- Portafilter and Filters: After each use, remove the portafilter, discard coffee grounds, and rinse thoroughly under running water.
- Drip Tray: Empty and rinse the drip tray daily. It is removable for easy cleaning.
- Steam Wand: Immediately after frothing milk, wipe the steam wand with a damp cloth. Briefly release steam to clear any internal milk residue.
- Water Tank: Empty and rinse the water tank daily, refilling with fresh water for each use.
- Exterior: Wipe the exterior surfaces of the machine with a soft, damp cloth. Do not use abrasive cleaners or solvents.
Descaling:
Over time, mineral deposits (limescale) can build up in the machine, affecting performance. Descale your coffee maker 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, 1:1 ratio).
- Fill the water tank with the descaling solution.
- Place a large container under the brewing head and steam wand.
- Turn the machine ON and allow it to heat up.
- Run half of the solution through the brewing head by turning the function dial to the coffee brewing position.
- Turn the function dial to the steam position and release steam through the wand until half of the remaining solution is used.
- Turn off the machine and let it sit for 15-20 minutes.
- Repeat steps 5-7 with the remaining solution.
- Empty the water tank, rinse it thoroughly, and refill with fresh water.
- Run several tanks of fresh water through both the brewing head and steam wand to rinse out any descaling solution residue.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No coffee flows out. | Water tank empty; coffee too finely ground or over-tamped; machine not primed; clogged filter. | Fill water tank; use coarser grind or less pressure when tamping; prime the machine; clean the filter and portafilter. |
| Coffee flows too quickly/weak coffee. | Coffee too coarsely ground or under-tamped; insufficient coffee grounds. | Use finer grind or tamp more firmly; use correct amount of coffee grounds. |
| No steam from steam wand. | Steam wand clogged; machine not heated to steam temperature. | Clean steam wand nozzle; wait for temperature gauge to reach steam range. |
| Water leaking from machine. | Water tank not seated correctly; drip tray full; seals worn. | Ensure water tank is properly seated; empty drip tray; contact customer support if seals are suspected. |
| Machine not turning on. | Not plugged in; power switch off; power outage. | Check power connection; ensure power switch is ON; check household power supply. |
