Technical diagram of a coffee maker with numbered parts for identification and assembly reference.BEFORE THE FIRST USE
- Check that all accessories for the device are present and that the unit is not damaged.
- Flush out the pipes. First, allow the water to run through without adding ground coffee to the filter of the portafilter. See section: 'use/coffee'. Afterwards, throw away the water.
- Flush out the steam nozzle. See section: 'use/hot water feature'. Afterwards, throw away the water.
- Clean all parts with a moist cloth.
USE
COFFEE
-
Fill the water reservoir with the desired amount of water. Make sure if the level is within the 'MIN' and 'MAX' indicators on the reservoir. The reservoir is removable. Open the lid; lift the reservoir out of the appliance to fill it and then carefully place it back in the appliance.
-
Plug the power cord into a socket. Make sure that the steam knob is in the off position. Press the on-off button; the appliance will start warming up. If all indicator lamps are lit, the appliance has warmed up and goes into standby mode.
-
Select the desired filter: the small filter for an espresso, the large filter for 2 cups or a double espresso. Place the filter in the portafilter. Make sure the dot on the filter is aligned with the groove in the portafilter.
-
Fill the filter with fresh, finely ground espresso coffee using the measuring spoon (1 scoop for the small filter, 2 scoops for the large filter). Press the ground coffee firmly and evenly using the presser on the back side of the measuring spoon. Remove any excess coffee from the edge. We recommend you fill the filter to ±3 mm from the edge.
-
Place the portafilter under the brew group. Hold the handle so that it connects correctly to the open-lock symbol on the appliance and fits into the groove. Turn it slowly to the right, to the closed-lock symbol on the appliance.
-
Place 1 or 2 cups on the drip tray.
-
Press the espresso button. The pressure gauge allows you to read the pressure during extraction.
-
When you have the desired amount of coffee in your cup, press the espresso button again to stop it.
⚠️ Never leave a running appliance unattended. The appliance does not stop automatically. You must stop it by pressing the espresso button.
- Remove the portafilter from the appliance. Place the retainer clip against the filter and bang the coffee grounds out of the filter. Clean the portafilter and dry it off for the next use.

Tips
- A clean coffee maker is essential to make great tasting coffee. Clean the appliance regularly according to the guidelines. Always use fresh, cold water in the coffee maker.
• Store coffee in a dry and cool place.
- The drip catcher can be removed to fit a large cup under the portafilter.
• Always make sure that the ground coffee is evenly spread out in the filter. This improves the permeation effect.
• To achieve the optimal coffee temperature, we recommend that you heat up the unit and the cup. Use the same method as for preparing coffee, but do not add ground coffee to the filter of the portafilter. Keep your cups above the unit, which acts as a cup warmer.
PRESSURE GAUGE
You can read the pressure/bars on the pressure gauge. It must be in the indicated region.
If the pressure is too low, check the following:

- Is the coffee fresh?
- Have you put enough pressure on the tamper? When pushing the ground coffee, you should use a force of ±15-20 kg.
- The coffee is ground too coarsely.
If the pressure is too high, check the following:

- Are the holes in the filter blocked?
- Have you put too much pressure on the tamper? When pushing the ground coffee, you should use a force of ±15-20 kg.
- The coffee is ground too finely.
STEAM NOZZLE
You use the steam nozzle to froth milk to achieve the perfect cappuccino or latte.
-
Fill the water reservoir.
-
Insert the plug in the power socket. Make sure that the steam dial is in the off position. Press the on/off button; the appliance will start warming up. If the indicator lamps are on, the appliance has warmed up and is in standby mode.
-
Fill a jug with cold, full-cream milk. (±100 ml milk for 1 cappuccino) Be careful not to overfill the milk jug. Frothing the milk will increase its volume.
-
Press the steam button.
-
First, allow the steam nozzle to warm up. Point the steam nozzle over the drip tray. Slowly turn the dial to ON and wait 10 seconds.
-
Turn the steam nozzle towards the milk jug. Bring the milk jug up to the steam wand and insert the steam nozzle a few millimetres into the milk.
⚠️ ATTENTION: the steam emitted by the steam nozzle is very, very hot.
- As the milk expands in volume, keep lowering the jug slightly until the steam nozzle tip is just below the surface of the milk. If you insert the steam nozzle too deeply into the milk, it heats the milk but does not froth air into the milk and no foam will form.
⚠️Do not use the steam feature for more than 5 minutes at a time.
-
When you obtain the desired amount of foam, turn the rotary knob to the off-position.
-
Clean the steam nozzle after every use.
⚠️ ATTENTION: the steam nozzle may still be really hot.

- Fill the water reservoir. Insert the plug in the power socket and press the on/off button.
- Place a cup under the steam nozzle.
- Turn the steam dial to ON. Hot water will flow from the steam nozzle.
- When you have enough water, turn the dial to the off position.
CLEANING AND MAINTENANCE
- Before cleaning the unit, pull the plug out of the power socket and let the unit cool down.
- Clean all removable parts (filters, portafilter, measuring scoop with tamper, drip tray, and grille) with clean warm water after use. Dry off the parts before putting them back. You can also clean these parts in the dishwasher.
- Wipe the unit housing clean with a soft, damp cloth to remove stains.
- Flush the unit regularly by brewing without putting ground coffee in the filter.
- Rinse the steam nozzle after each use with hot water. Remove the tube and rubber from the steam nozzle and clean in hot water with detergent. You can also clean the tube in the dishwasher. Dry off the parts before putting them back. You can clear the pipe opening using a 1 mm needle.
⚠️Do not immerse unit, cord, or plug in water or other liquid.
⚠️Never use aggressive or abrasive cleaning agents.
DESCALING
When?
Descale the unit regularly, on average every 2 to 4 weeks. Regularly descaling ensures the quality of your coffee will be consistent, lowers energy consumption, and extends the espresso machine's working life.
How?
- Fill the water reservoir with water and descaling product for espresso machines up to the descaling indicator ÷ diluted according to the instructions on the product packaging.
- Place the portafilter with filter but without ground coffee in the unit.
- Place a collection container of at least 500 ml under the brewing head and the steam nozzle.
- Insert the plug in the power socket, turn on the unit, and let it heat up.
-
Press the espresso button. The lamp will start blinking. The appliance will stop after about one and a half minutes. The espresso button lamp will stop blinking. Empty the collection container. Now put the collection container back in and repeat this procedure.
-
Press the steam button and wait for the lamp to turn on. Turn the steam dial to ON. Let the appliance steam for 1 minute then turn the knob back to 'OFF'.
- The unit must now be flushed with clean water to ensure no lime residue remains. Rinse the water reservoir and fill it with clean water. Empty the collection container.
- Repeat the descaling procedure, but now with clean water in the reservoir.
PROBLEMS AND SOLUTIONS
| PROBLEMS SOLUTIONS | |
| The coffee no longer flows. • There is no water in the reservoir. Fill the water reservoir.• The ground coffee is too fine or was compressed too tightly.

| No or little steam comes out of the steam nozzle. | • There is no water in the reservoir. Fill the water reservoir.• To use the steam feature on the appliance, you must first press the steam button before turning the dial to ON.• The steam nozzle is blocked. Remove the tube and rubber from the pipe. You can clear the pipe opening using a 1 mm needle.• Descale the appliance. See section: ‘cleaning and maintaining/descaling’. |
| Water leaks underneath the appliance. • This happens when you add too much water to the reservoir. Make sure you don’t overfill past the MAX indicator. | |
| Water leaks past the filter. | • There is ground coffee on the edge of the filter. Remove the excess coffee from the rim. |
| The filter is stuck in the portafilter. | • Make sure the dot on the filter is aligned with the groove in the portafilter. Turn the filter until the small recess is turned to the side of the handle. |
