4.4 Installation 

  • Place the appliance on a work surface away from water faucets and sinks.  
  • Check that the voltage of the outlet corresponds to the value indicated on the appliance rating plate. Connect the appliance to an efficiently grounded electrical socket with a minimum rating of 10A only. The manufacturer declines all liability for any accidents caused by the absence of an efficient ground system. 
  • If the plug fitted to the appliance does not match the electrical socket, have the outlet replaced with a suitable type by a qualified electrician. 
  • Never install the appliance in environments where the temperature may reach 0°C (32°F) or lower (the appliance may be damaged if the water freezes). 


  • The filter eliminates the taste of chlorine in the water. To install the filter, proceed as follows:  
  • Release the filter support from its slot by pulling it upwards (fig. 1). 
  • Remove the Antichlorine filter from the plastic sachet and rinse it under a running tap (fig. 2).  Open the filter support and carefully put the filter in place as shown in fig. 2.  
  • Close the filter container carefully (fig. 2), and reposition it in its slot, pushing it firmly downwards.  
  • The Antichlorine filter should be replaced after 80 cycles, and at least after every 6 months of operation. 


When using the appliance for the first time, all the accessories and the internal circuits must be washed as follows:

  • DRIP COFFEE MAKER: Make at least two carafes of coffee without using ground coffee. 
  • ESPRESSO MAKER: Make at least four cappuccinos without using ground coffeeand using water instead of milk. 


7.1 Setting the clock 

When the coffee machine is connected to the outlet for the first time, the numbers 0:00 will flash on the display. 
To set the time, proceed as follows: 

  • Press the “hour” button (Fig. 3) for about 2 seconds until the number of hours on the display begins to increase.
  • Before the display stops flashing (about 5 seconds), set the hour by pressing the “hour” button repeatedly. 
  • Set the minutes by pressing the “min” button (Fig. 3) repeatedly. (To speed up the operation, hold the button down.) 
  • After setting the time, wait 5 seconds. When the display stops flashing, the time set is stored.  

To reset the time, press the HOUR button for about 2 seconds, and then follow the procedure as described starting from point 2.  
Please note: In the event of a temporary power failure, the time set does not remain stored in the memory. 

7.2 Programming the automatic start (AUTO BUTTON) 

The appliance can be programmed to make drip coffee automatically. First, make sure that the time is set correctly.  To set the delayed start (i.e. the time you want the coffee to be made), proceed as follows: 

  1. Press the AUTO button (Fig. 4) for about 2 seconds until 0:00 flashes on the display. 
  2. Before the display stops flashing (about 5 seconds), set the desired hour by pressing the “hour” button repeatedly.
  3. Set the minutes by pressing the “min” button repeatedly.
  4. After 5 seconds, the display will stop flashing and the programmed time will be stored. 
  5. After you have programmed the machine as described above, just press the AUTO button to have coffee made at the time set (the AUTO indicator light will illuminate). 

Please note: 

  • If you want to change the start time after it has been set, press the AUTO button for about 2 seconds and then set a new time as described starting from point 2.  
  • Keep in mind that at the time set, the appliance will start to make drip coffee only. The espresso maker does not come on. 

7.3 Length of warming time (Automatic shut off time) 

  • The appliance is factory-set to keep the coffee warm for two hours after startup. However, this setting can be changed as follows: 1. Press the ON/OFF button (Fig. 5) for about 2 seconds until 0:00 flashes on the display. 
  • Modify the time by repeatedly pressing the HOUR button (and also the MIN button if required). 
  • After setting the time, wait 5 seconds. When the display stops flashing, the time will be stored. 

Please note: If 0:00 is set, the appliance switches off. (You can set a time within 1 minute and 11hours and 59 minutes).

7.4 “1-4” cups button 

You can enhance the flavor of your coffee by pressing the “1- 4” button after the “ON/OFF” button. This feature activates a unique brewing process, slowly releasing water into the filter basket; saturating coffee grounds a little at a time extracting the best flavor and aroma from your coffee.  
To activate, press the “1-4” button (fig. 6); the light on the but ton will illuminate.  
Press the button again to turn the selection off.  
Do not use this button if brewing an entire carafe of coffee. You can select this function even when using the auto function.

7.5 Making drip coffee 

Open the filter-holder door, rotating it towards the right (fig. 7). 
Fill the carafe to the level indicator relative to number of cups of coffee you wish to prepare; taking care not to exceed the MAX level (fig. 8), otherwise, in order to not overfill the machine, the excess water will spill out from the back of the unit. 

  • Then pour the water into the water-fill compartment of the appliance (fig. 9). 
  • Position the gold tone filter into the filter-holder (fig. 10). • Put the ground coffee in the filter using the measuring spoon supplied and level it off evenly (fig. 11). As a general rule, use a level measure of coffee (approx. 7 grams) for every cup of coffee required (for example, 10 measures to obtain 10 cups).  
  • Close the filter-holder door and place the carafe, with cover in place, onto the warming plate. 
  • Press the ON/OFF button. The light on the button indicates that the drip coffee-maker is in operation. 
  • The coffee will begin to dispense after a short time.  It is perfectly normal for the appliance to emit steam while the coffee is percolating.  
  • To keep the coffee hot after the percolation process has finished, place the carafe on the hot plate and leave the machine turned on (with the drip coffee light on): the coffee in the carafe will be kept at the right temperature.  
  • To turn off the machine press the ON/OFF switch. 


The first time you use the appliance, wash all accessories and rinse the internal circuits by proceeding as though you were making coffee until you have used at least two tanks of water.  You can then proceed to make coffee. 

8.1 Preheating the coffee unit 

To make espresso coffee at the right temperature, the coffee maker should be preheated as follows: 

  1. Press the ON/OFF switch (fig. 12) to turn the appliance on.  The power light (B3) comes on. 
  2. Insert the filter to the filter holder (fig. 13). Make sure the projection is correctly inserted in the slot. Attach the filter holder with filter to the appliance (fig. 14) without adding pre-ground coffee. Use the smaller filter to make one coffee or the larger filter to make two coffees. 
  3. Place a cup under the filter holder. Use the same cup as will be used to prepare the coffee in order to preheat it.
  4. Wait until the light comes on and immediately afterwards press the button (fig. 15). Continue delivering water until the light goes off, then interrupt delivery by pressing the same button and empty the cup. 

(It is normal for a small and harmless puff of steam to be given off when removing the filter holder). 

8.2 How to make espresso coffee using pre ground coffee 

  1. After preheating the appliance and filter holder as described in the previous paragraph, use the smaller filter to make one coffee or the larger filter to make two coffees. 
  2. To make just one coffee, place one level measure of pre ground coffee (about 7 g) in the filter (fig. 16). To prepare two coffees, place two loosely filled measures (about 6+6  g) of pre-ground coffee in the filter. Fill the filter a little at a time to prevent the pre-ground
    coffee from overflowing. 

For correct operation, before filling with pre-ground coffee, make sure there are no coffee residues left in the filter from the last time you made coffee. 

3.Distribute the pre-ground coffee evenly and press lightly with the presser (fig. 17). 

4.Correct pressing of the pre-ground coffee is essential to obtain a good espresso. If pressing is excessive, coffee delivery will be slow and the froth will be dark. If pressing is too light, coffee delivery will be too rapid and the froth will be skimpy and light coloured. Remove any excess coffee from the rim of the filter holder and attach to the appliance. Turn the handle firmly towards the right (fig. 14) to avoid water leaking out. 

5.Place the cup or cups under the filter holder spouts (fig.  18). You are recommended to warm the cups before making coffee by rinsing them with a little hot water. 

6.Make sure the light is on (if off, wait until it comes on), then press the button (fig. 15). When the de sired amount of coffee has been delivered, press the same button to interrupt the flow. 

7.To remove the filter holder, turn the handle from right to left. 

Danger of burns!  
To avoid splashes, never remove the filter holder while the appliance is delivering coffee. 

8.To dispose of the used coffee, block the filter in place using the lever incorporated in the handle, then empty the grounds by turning the filter holder upside down and tap ping it firmly (fig. 19). 

9.To turn the appliance off, press the ON/OFF button on the left side of the machine.

How to prepare espresso coffee using pods

  1. Preheat the appliance as described in the section “PRE HEATING THE COFFEE UNIT”, making sure the filter holder is attached. This obtains a hotter coffee. 

Please note: 
Use pods conforming to the ESE standard, indicated on the pack by the following symbol.   The ESE standard is a system accepted by leading pod producers and enables espresso coffee to be prepared simply and cleanly. 

  1. Place the small filter in the filter holder, making sure the projection is correctly inserted in the slot as shown in fig.  13. 
  2. Insert the pod, centring it as far as possible on the filter (fig. 20). Always follow the instructions on the pod pack to position the pod on the filter correctly. 
  3. Attach the filter holder to the appliance. Always turn as far as it will go (fig. 14). 
  4. Proceed as in points 5, 6 and 7 in the previous section. 


  1. Prepare the espresso coffees as described in the previous sections, using sufficiently large cups. 
  2. Press the button. The corresponding light comes on (fig. 21). 
  3. In the meantime, fill a recipient with about 3.5 oz/100 grams of milk for each cappuccino to be prepared. In choosing the size of the recipient, bear in mind that the milk doubles or triples in volume. 

Please note: 
You are recommended to use skimmed or semi-skimmed milk at refrigerator temperature (about 5°C). 

4.Place the recipient containing the milk under the cappucci no maker. 

5.Wait until the light comes on (fig. 21). The light comes on to indicate that the boiler has reached the ideal temperature for steam production. As the boiler heats up, it is normal for a little water and steam to be given off into the drip tray. 

6.Remove the cappuccino maker by rotating to the left (fig.  22). During this operation, avoid touching the boiler outlet as it is hot. Then place the recipient containing the milk under the cappuccino maker. 

7.Dip the cappuccino maker in the milk for a few millimeters (fig. 23). Turn the steam dial to the ON position (fig.  24). Steam is delivered from the cappuccino maker, giving the milk a creamy frothy appearance. For a creamier froth, immerse the cappuccino maker in the milk
and move the container with slow upward movements. 

8.When the milk has doubled in volume, immerse the cappuccino maker deeply and continue heating the milk.  When the required temperature (the ideal is 60°C) and froth density is reached, interrupt steam delivery by turning the steam dial to the OFF position and press
the button. 

9.Pour the frothed milk into the cups containing the espresso coffee prepared previously. The cappuccino is ready. Sweet en to taste and if desired, sprinkle the froth with a little cocoa powder 

 Please note: 

  • To prepare more than one cappuccino, first make all the coffees then at the end prepare the frothed milk for all the cappuccinos. 
  • To make coffee again after the milk has been frothed, cool down the boiler first or the coffee will be burnt. To cool the boiler, place a container under the boiler outlet, press the button (fig. 15) and deliver water until the OK light goes off. Press the button again and prepare the coffee as described in the previous paragraphs. 

You are recommended to deliver steam for a maximum of 60 seconds and never to froth milk more than three times consecutively.

 Important:  For hygiene reasons, the cappuccino maker should always be cleaned after use. 
Proceed as follows: 

  • Deliver a little steam for a few seconds (points 2 and 5 of the previous section) by turning the steam dial (fig. 24).  This causes the cappuccino maker to discharge any milk left inside. Turn the appliance on again by pressing the ON/ OFF button. 
  • With one hand, hold the cappuccino maker spout firmly,  with the other, release the cappuccino maker by turning it  anticlockwise, then pull off downwards (fig. 25). 
  • Remove the steam connection nozzle from the spout by pulling it downwards. 
  • Wash the cappuccino maker and steam connection nozzle thoroughly with warm water. 
  • Make sure the two holes shown by the arrows in fig. 26 are not blocked. If necessary, clean with a pin. 
  • Put the steam connection nozzle back, pressing forcefully upwards to insert it onto the steam tube. 
  • Replace the cappuccino maker by pushing upwards and turning clockwise.


  1. Press the ON/OFF switch (fig. 12) to turn the appliance on.  The power light comes on. 
  2. Wait until the light comes on. 
  3. Place a recipient under the cappuccino maker.
  4. When the light comes on, press the button (fig. 15) and at the same time turn the steam dial to ON (fig. 24). Water comes out of the cappuccino maker.
  5. To interrupt hot water delivery, press the button again and turn the steam dial to OFF. 

You should not deliver hot water for more than 60 seconds. 


While cleaning, never immerse the coffee maker in water.  It is an electrical appliance. 
Before cleaning the outside of the appliance, turns it off, unplug from the mains socket and allow to cool. 

11.1 Espresso coffee filter cleaning and maintenance 

About every 300 coffees or when the coffee is delivered from the  filter holder a drop at a time or not at all, clean the pre-ground  coffee filters and filter holder as follows: 

  • Remove the filter from the filter holder. 
  • Remove the filter cap (fig. 27) by unscrewing in the direction indicated by the arrow on the cap. 
  • Remove the frother from the container by pushing it from the cap end. 
  • Remove the gasket. 
  • Rinse all components and clean the metal filter thoroughly in hot water using a brush (fig. 28). Make sure the holes in the metal filter are not blocked. If necessary, clean with a pin (see fig. 29). 
  • Replace the filter and gasket on the plastic disk as shown in fig. 30. Make sure to insert the pin on the plastic disk into the hole in the gasket indicated by the arrow in fig. 30. 
  • Replace the assembly in the steel filter container (fig. 31), making sure the pin is inserted in the hole in the support  (see arrow in fig. 31). 
  • Finally, screw on the cap. 

Failure to clean as described above invalidates the guarantee. 

11.2 Cleaning the boiler outlet 

About every 300 coffees, the espresso boiler outlet must be cleaned as follows: 

  • Make sure the appliance is not hot and that it is unplugged from the mains; 
  • Use a screwdriver to release the screw fixing the espresso  boiler outlet (fig. 32); 
  • Remove the boiler outlet; 
  • Clean the boiler with a damp cloth (fig. 32);
  • Clean the outlet thoroughly with hot water using a brush.  Make sure the holes are not blocked. If necessary, clean with a pin (fig. 29). 
  • Rinse under running water, brushing all the time.
  • Replace the boiler outlet, making sure it is correctly positioned on its gasket. 

Failure to clean as described above invalidates the guarantee. 

11.3 Other cleaning operations 

  1. Do not use solvents or abrasive detergents to clean the coffee maker. Use a soft damp cloth only. 
  2. Clean the filter holder, filters, drip tray and water tank regularly. To empty the drip tray, extract the cup tray grille, remove the water and clean the tray with a cloth: then reassemble the drip tray. 

While cleaning, never immerse the coffee maker in water. It is an electrical appliance. 


12.1 Descaling the espresso coffee unit

We recommend descaling the coffee maker about every 200 coffees. We recommend using commercially available De’Longhi descaler. 
Proceed as follows: 

  1. Remove the water softener filter and fill the tank with the descaler solution, obtained by diluting the descaler with water following the instructions on the pack. 
  2. Press the ON/OFF switch (fig. 12) to turn the appliance on.  The power light comes on. 
  3. Make sure the filter holder is not attached and position a recipient under the boiler outlet. 
  4. Press the button and deliver about 1/4 of the solution in the tank, turning the steam dial at intervals to allow a little solution to flow out through the cappuccino maker spout. Then stop the flow by pressing the button again and leave the solution to act for about five
  5. Repeat point 4 a further 3 times until the tank is completely empty. 
  6. To eliminate residues of solution and scale, rinse the tank well, fill with clean water (without descaler).
  7. Press the button (fig. 15) and deliver water until the tank is completely empty. 
  8. Repeat operations 6 and 7 again. 
    Repair of damage to the coffee maker caused by scale is not covered by the guarantee unless descaling is performed regularly as described above. 

12.2 Descaling the drip coffee unit 

Over time, calcium in the water may cause obstructions, reducing the efficiency of the coffee maker. You are recommended to descale the coffee maker about every 40 coffees. To descale, always use special commercially available descaling products for drip coffee makers. 

  1. Dilute the product in the jug, following the instructions on the descaler pack; 
  2. Remove the antichlorine filter and pour the descaler solution into the tank; 
  3. Place the jug on the warming plate; 
  4. Press the switch, percolate the equivalent of one cup and then switch off the appliance; 
  5. Leave the solution to work for 15 minutes, then repeat operations 4 and 5. 
  6. Turn the appliance on and deliver the water until the tank is completely empty. 
  7. Rinse by operating the appliance with water only at least 3 times (3 complete tanks of water).
