Make sure that there is enough water in the tank. Running the machine without water may damage the pump. Water levels should be checked visually. It is recommended to use water with a low mineral content. The quality of the water will affect the taste and quality of your coffee as well as help avoid future malfunctions.

---

What is the start-up mode?

When turned on for the first time, the machine enters start-up mode. The pilot light comes on and flashes while the machine heats up, until the right temperature is reached. During this process no service can be provided.

---

How do I use the machine for the first time or after a long interval to replace the water in the circuit?

Turn the coffee maker on with the general switch in position (I). Attach the empty filter holder with a receptacle underneath. Press the coffee switch and let approximately half a tank of clean water flow through.

---

How do I prime the machine?

The machine should be primed if no coffee comes out, after a period without use, after generating steam, or if the tank has been emptied. In the DUO model, repeat the first-time use steps. In the UNO model, the priming procedure should be carried out:

1. With the coffee maker on, turn on the steam tap.
2. Turn on the water function and release some water (a cup) through the steam wand.
3. Turn off the water function and turn off the steam tap. The coffee maker is now ready to use.

---

What should I do after producing steam in the UNO model?

Wait 5 minutes before making coffee, or carry out the priming operation, but let the water flow until the temperature pilot light stops flashing.

---

What should I check to make coffee?

Check the system for ground coffee, pod, or capsule.

---

What type of coffee can be used?

Any type of coffee may be used, ground or pod, thanks to the 5 filters supplied: 2 ground filters (1- and 2-cup), 2 pressurized filters (1- and 2-cup Cream+) and 1 pod filter.

---

What is the recommendation for optimal coffee results?

For optimal results, it is advised to use ready mixes for espressos, as they have the appropriate ground size for use with ground filters. If the results are not as expected, use pressurized filters, which will give good results regardless of ground size. Regardless of the type of filter used for ground coffee, and depending on whether the coffee comes out quickly or slowly, it is recommended to change the type of coffee, the ground size or experimenting with compactness to suit preference.

---

How to make coffee using ground coffee?

1. Turn on the machine, turning the ON/OFF switch to position (I). Place the filter holder (with filter) in the group.
2. UNO/DUO models: Wait for the pilot light to come on without flashing. This takes approximately 1.5 minutes. This shows that the water has reached the right temperature. Turn on the coffee switch and let water flow through the group. Performing this procedure before making coffee will eliminate residues and establish the temperature for optimal service.
3. The filter must be filled to 3/4 its capacity, once the coffee has been tamped down.
4. Clean the coffee residues that have been deposited on the edges of the filter to ensure a perfect fit.
5. Attach the filter holder to the group and turn from left to right, exerting sufficient pressure at the end.
6. Place the cup or cups on the tray and turn on the coffee switch.
7. When the coffee is done, turn off the coffee switch.

It is normal for the ground coffee in the filter holder to have a liquid consistency if the filter holder is immediately removed after delivery.

---

How to make coffee using pods or FAP-capsules?

Use the specific filter holder for capsules or pods. Place the pod in the filter holder. Follow points 1, 2, 5, 6 and 7 as in the previous section.

---

How to make coffee using Pod (fixed filter holder)?

1. Follow Points 1 and 2, as in the section for ground coffee.
2. Place a tablet on the filter holder and turn it gently to the right as far as it will go. Do not force it, closure is smooth.
3. Point 5, 6, 7 and notes as in the previous section.

Do not remove or turn the filter holder while the water is running through, as the machine is under pressure at this time.

---

What are some general tips for making coffee?

• The filter holder should always be fitted in the machine to keep it warm, in the closed position.
• Only in UNO models: If the coffee does not come out hot enough, turn on the steam switch for 10 seconds. This raises the temperature of the machine.
• Place the cups on the cup warmer. Espresso is best at optimal temperature (40°C/105°F).
• The coffee will continue to drip out for a few seconds after the coffee is switched off.
• To obtain perfect espresso, the coffee should be firmly tamped down.
• The right working pressure depends on the type of coffee and the ground size. In all cases, a working pressure of between 9 and 12 bar is adequate. In the PID versions, the temperature is shown on the screen included for this purpose.
• The machine’s maximum working pressure can be adjusted using the OPV next to the coffee group. To do this, use the blind filter fitted in the filter holder, attach it to the group and turn on the coffee switch. The pressure can be adjusted by turning the OPV using a flat-head screwdriver. Turning it to the right increases the maximum working pressure and turning it to the left reduces it.

How to program the coffee dose in PID models?

PID models have a coffee dose control function, so that the amount of coffee required can be adjusted for both the available options (small coffee, large coffee). There is a 3-position coffee switch for this process. The two available coffee selections are obtained by turning the switch to the top or bottom positions, while the midpoint turns off the coffee function. The coffee switch on the two PID models is not a permanent setting. Once the function has been activated, it returns to its original position. The switch does not have to stay in the working position; once the programmed amount of coffee has been obtained, the function will stop automatically. To program the dose at either of the two selections, just turn the switch to the desired position until the required dose is obtained. On releasing it, the dose will have been programmed.

To avoid the risk of injury, do not open the brew chamber during the brew process.

How to make cappuccino?

True ‘cappuccino’ contains 25 milliliters of espresso coffee and 125 milliliters of cold steam-whipped milk, which goes from 3 or 4 degrees centigrade to nearly 55 degrees centigrade. Use fresh cow’s milk with a protein content of over 3.2 percent and a fat content of 3.5 percent. Whip only the amount required for one cup in a steel jug to prevent it from mixing with other odors or tastes. The density of the cream must be uniform and there must be no separation from the liquid, or holes or bubbles.

What are some tips for making cappuccino?

• TEXTURE: Obtaining cream

  To obtain what is known as a ‘velvety’ consistency, place the frother nozzle just beneath the surface of the milk. To do this, move the nozzle at different angles (constantly under the surface of the milk) to obtain an emulsion with the circulating air. Once textured, the milk may double its volume. Remember to move the jug and the steam nozzle very close to the surface of the milk. Upon completion of this operation, the milk will be textured but still cold.

• TEMPERATURE: Heating the milk

  Once you have obtained the texture, submerge the steam nozzle as far as you can into the jug. Move the jug in circles to heat the milk until it reaches the temperature you want. Texturing should be done immediately beneath the milk’s surface, while the nozzle should be placed deeper for heating. Once the milk is hot and textured, it is ready to be served in the cup by adding it to the espresso base.

---

What are some possible problems when making cappuccino?

The cream may be too thin and lack consistency. One possible reason is that the milk has already been heated. The milk has been overheated (the steam nozzle has been placed too far into the jug and the milk has been heated without allowing the air to circulate on the surface) before the required texture has been attained. Step 1 (texturing) has not been performed properly and the air has not been allowed to work the milk.

---

How to make hot water in the UNO model?

1. Put a cup below the steam nozzle.
2. Turn the hot water/steam knob and press the switch (the pilot light will come on). Carry out the reverse operation to obtain the required water.

Do not heat the milk to over 75°C. Beyond this temperature you will scald the milk and it will not be suitable for cappuccino. The espresso is released at 75-80°C. The milk is textured and heated to between 55-70°C. It is important to maintain these temperatures for serving. The cups should therefore be warmed on the cup warmer. If this is not possible, heat the cup with hot water prior to use.
