Chapter 5. Initial Use
- Fill the water tank with cold water up to the MAX level of the tank.
- Press the Power button; the Power indicator light turns on and the coffee machine starts to preheat automatically. Once the preheating is finished, all the buttons will light up continuously. This preheating process takes about 2 minutes.
- Place a cup under the Steam Wand. Turn on the steam knob. Let the hot water flow out of the steam wand for about 8 seconds, then turn off the steam knob. This process primes the pump for the first use.
NOTE: There will be a loud noise and little shake when the machine is running for the first time. It's normal for a 20 Bar pump. The noise will be weak in future use.
- Insert the Filter into the Filter holder.
NOTE: The filter might be a little tight and hard to take it out from the filter holder when you want to change the filter. You can use another filter to pry it out.
- Offset the filter holder without coffee grounds 45° to the left and insert into the brew head, turn it to the right to lock it in place. The completed filter holder must be installed perpendicular to the machine or slightly tilted to the right. Diagram illustrating the filter holder insertion: The filter holder is shown being inserted into the brew head at a 45-degree angle to the left, then turned to the right to lock. A 'Lock' indicator is present.
- Place an empty cup under the filter holder and press the single or double button to brew.
- After the brewing cycle has finished, pour the water out.
Now your coffee machine is ready to use.
Chapter 6. Making the Espresso
Cold filter holders, filters, and cups reduce the extraction temperature, which affects the quality of the espresso. It is recommended to run a brewing cycle without coffee grounds to preheat them before extraction.
- Remove the filter holder and fill the filter with coffee grounds using the tamp spoon provided with the machine. We recommend 7g for a single shot and 14g for a double shot. The amount will vary depending on your preferences and the coffee grounds you used.
- Tamp the coffee grounds with the tamp spoon. The coffee grounds must be pressed evenly to obtain a well-leveled and flat surface.
- Make sure the steam knob is on the “OFF” position.
- Press the temperature and the coffee brewing button according to your favor.
NOTE: After selecting the mode, the machine will start to work 2 seconds later. When in manual mode, press the Coffee Brewing Button again to stop when you reach your desired amount, or the machine will stop automatically after 60s. The max time for manual should not exceed 1 min. It is not recommended to use finer coffee powder from grinding bean gear below 8 levels for extraction, as this will cause the filter to clog and lead to a lack of water indication. If the screen flashes a water shortage sign when there is water in the tank, remove the filter and soak in boiling water for about 10 mins, then replace the coarser powder for re-extraction.
The flavor of your coffee will depend on many factors, such as the type of coffee beans, degree of roast, freshness, coarseness or fineness of the grind, dose of ground coffee, and tamping pressure. Experiment by adjusting these factors just one at a time to achieve the taste of your preference.
Chapter 7. Frothing Milk
Before starting, it is important to slightly move the steam wand outwards to insert the jug directly under it and facilitate the movements required to froth the milk correctly.
- Press the steam button. The machine will start to preheat and the corresponding icon on the screen will start to flash if the temperature is not high enough to make steam. Once the preheating has finished, the Preheat icon will disappear, and only the steam icon will be shown.
- Turn the steam knob slightly counterclockwise to eliminate any condensation from the wand, then turn the knob off again.
- Place the jug, half-filled with cold milk, under the steam wand.
Diagrams illustrate milk frothing technique. The 'OK' diagram shows the steam nozzle positioned just below the milk surface, angled towards the side of the jug to create a vortex. The 'NO' diagram shows incorrect positioning, either too deep or too shallow.
- Place the steam nozzle just below the surface of the milk. If it is inserted too deep or not deep enough, the milk will not be frothed correctly. It is important to keep the Steam Tube not at the center but close to the edge of the jug, with an appropriate angle to produce a stronger vortex.
- Turn the steam knob to the [steam/hot water control] position. The steam will come out of the steam wand.
NOTE: The entire operation should last no longer than 3 minutes, because the machine will stop making steam automatically after 3 minutes of continuous steaming. To froth the milk correctly, the steam nozzle must always be in contact with the milk and not with the froth. Therefore, as the layer of froth increases, the jug must be slightly raised trying to keep the Steam Tube in contact with the milk, without touching the bottom of the jug.
- Once the desired frothing result has been achieved, the steam nozzle must be pushed deeper to heat the milk well.
NOTE: It is advisable to always keep a hand on the rounded part of the jug to feel the temperature increase of the unfrothed milk.
- Once the desired result has been achieved, turn the steam knob to "OFF" position to stop dispensing steam and remove the jug.
NOTE: To make the froth more compact, it is advisable to lightly tap the jug on a flat surface after frothing.
- Press the steam button again to quit the steam mode. Pour the frothed milk into the coffee.
- Turn the steam knob on to eliminate any residue milk from the wand, then turn the knob off again.
NOTE: When finished with the steam, be sure to close the steam knob. After finishing the steam function, press the steam button to return to standby mode. After steam function, the machine is under overheat protection. (Refer to Over-heat protection to cool up the machine)
WARNING: The steam wand may be very hot during and after use. To avoid burns, move it only by placing your fingers on the rubber tip fitted on the steam wand.
Chapter 8. Over-heat Protection
When the machine returns to standby mode after steam function (the maximum continuous steam cannot be more than 122 seconds), an overheating icon flashes on the screen, indicating that the coffee machine is under overheating protection. Do not make coffee immediately, as the temperature of the boiler is very high and must cool down first, or the coffee will be burnt and may come out of the filter holder.
Please proceed as below 4 steps to cool up the machine:
- Under the overheat protection, turn the steam knob to the [steam/hot water control] position to make hot water.
- Let hot water come out from the steam wand to cool down the boiler.
- Once the temperature of the boiler has cooled down, the Overheat icon will disappear from the screen.
- Turn the knob back to the "OFF" position, and the coffee machine is ready for the next brew.
NOTE: If you still want to brew coffee without cooling down the machine, press the Coffee Brewing Button again, and the machine will start working. (This is not recommended because the coffee will have a burnt taste.)
Chapter 9. Resetting Default Mode
To reset the machine to the default mode, keep pressing the coffee brewing and temperature buttons simultaneously for 5 seconds. The machine will beep 3 times, and all the buttons will flash 5 times. The machine will return to its original default settings.
Chapter 10. Auto Shut-off
The machine will shut off automatically if no operation is selected after 15 minutes on standby mode. All the buttons will turn off. To start the machine, press the Power button again.
Chapter 11. Cleaning and Maintenance
Cleaning the Filter Holder and the filters
If you find that the filter is blocked with very fine powder while brewing coffee, immerse the filter in boiling water for 10 minutes to dredge it, then rinse it with running water.
WARNING: To avoid burns, the filter must only be removed when the filter holder has cooled down completely. Wash them with warm water. Do not wash any of the parts in the dishwasher.
Cleaning the Steam Wand
Immediately after frothing milk, turn the steam knob on to purge out any residual milk from the wand. Clean the wand with a damp cloth. If the hole of the steam nozzle becomes blocked, ensure the steam knob is in the STANDBY position. Press the power button to turn the machine off and allow it to cool. Use a thin iron wire to unblock the hole.
Cleaning the Brew Head
Regularly remove any coffee grounds from the brew head using a brush. Insert the filter holder into it without using coffee grounds. Place a cup under the brew head and press the coffee brewing button twice to fill the cup. Then remove the filter holder from the brew head and clean it with a dry cloth.
WARNING: Do not try to disassemble the brew head. It will damage the Brew Head and lead to leakage.
Chapter 12. Descaling
After 500 brew cycles, it is necessary to run a descaling cycle, otherwise a descaling warning will appear at each start-up.
Fill the water tank with descaling agent (4 parts water to 1 part descaling agent) up to the Max marking. Place a cup on the drip tray and keep pressing the Temperature and Steam buttons together for 5 seconds. The machine will start the descaling cycle and run for 7 minutes, then stop automatically. Repeat the previous steps until the water with descaling agent is running out. Next, repeat the process two more times using only CLEAN TAP WATER without any descaling agent.
