PREPARING THE APPLIANCE

Wash all accessories with warm water and washing-up liquid, then proceed as follows:

  1. Locate the beans container in the (A2) coffee mill (fig.
    1).The container is correctly in place when the arrow ▲ aligns with the symbol and a “click” is heard (fig. 2).

  2. Locate the drip tray (A10) together with the cup grille (A8) and drip tray grille (A9) (fig. 3);

  3. Take out the water tank (A14) (fig. 4) and fill with fresh clean water, taking care not to exceed the MAX level (fig. 5).

  4. Put the tank back in the appliance.

Important: Never operate the appliance without water in the tank or without the tank.
Please note: You should customise water hardness as soon as possible following the instructions in section “7. Settings menu”.

SETTING UP THE APPLIANCE

  1. Plug the power cord connector (C6) into the socket (A16) at the back of the appliance (fig. 6), then plug into the mains socket. Make sure the main switch (A17) at the back of the appliance is pressed and in the I position (fig. 7);

  2. Place a container of at least 100 ml capacity under the hot water spout (next to the coffee spout (A18)) as illustrated (fig. 8).

  3. Press the button (B6) next to the indicator light (fig. 9): delivery will start and then stop automatically. Empty the container.
    Before using the coffee maker, the internal circuits of the machine must be rinsed. Proceed as follows:

  4. Attach the filter holder (C1) complete with filter to the appliance. To attach correctly, align the filter holder handle with “INSERT” (fig. 10), then turn the handle to the right until it is aligned in the “CLOSE” position;

  5. Place a container under the filter holder and the steam wand (A6);

  6. Press the OK button (B5): delivery will start (fig. 11);

  7. When delivery has finished, turn the steam dial (A4) (fig.

  1. and release the jet for a few seconds so as to rinse the steam circuit: to ensure best possible results, repeat the operation 3 or 4 times. The purpose of this procedure is to purge any water from the circuit before using steam to prepare a beverage.

The appliance is ready for use.
Please note: We also recommend rinsing the internal circuits if the appliance is not used for a long period.
The first time you use the appliance, you need to make 4-5 cups of coffee before the appliance starts to give satisfactory results.
Pay particular attention to the quantity of pre-ground coffee in the filter ((C2) or (C3)) (see instructions in section “4.1 Step 1 – Grinding”).
Proceed as described in section “The “perfect dose””.

PREPARATION OF COFFEE

4.1 Step 1 – Grinding

  1. Put coffee beans in the container (A2) (fig. 13). It is best to grind only a quantity of beans sufficient for immediate use, so that the coffee will always be fresh.

  2. Select the grinding level (fig. 14). The factory setting is 5 (medium ground). If this is too fine or too coarse, adjust the level according to personal taste and to the type of coffee being used (the adjustment must be made only when the coffee mill is in operation).
    Please note: A grinding level between 3 and 6 is recommended for most coffees. A grinding level of 1 or 2 is very fine and should be used with special coffees only (light roasted)

  3. Place the ground coffee filter (C2) or (C3) in the filter holder (C1) (fig. 15); If the 2-cup filter is in use, press the 2x button (B3): this will also double the quantity of espresso coffee delivered from the spout.

  4. Set the quantity by adjusting the dial (B2), starting from the minimum position (fig. 16).
    Refer to the section on “Adjusting the quantity of ground coffee in the filter” for further indications.

  5. Attach the filter holder to the outlet of the coffee mill (A19), aligning it with “INSERT”, then turning it to the right.
    Grinding begins when the filter holder reaches the CLOSE position, then stops automatically.

Adjusting the quantity of ground coffee in the filter

De Longhi EC935X Coffee Maker - ground coffee

Different varieties of coffee bean give different results when ground: consequently, the initial adjustment of the dosage requires special care.
This illustration shows how to regulate the dosage, based on the roast colour: this should be taken as a general guide, given that in practice, the final adjustment can vary according to the composition of the beans.

  1. Set the dosage starting from the minimum position.
  2. Looking at the roast colour of your particular beans, turn the dial slowly to find the right adjustment.

4.2 Step 2 – Tamping

  1. Following the grinding step, bring the tamping lever (A20) down completely (keeping the filter in place under the outlet) (fig. 17). For a perfect result, repeat the step twice.
  2. Keep the tamping lever fully down when removing the filter holder (fig 18) and then return the lever to its initial position.
  3. Having checked that the dosage is as required (see “The “perfect dose””), attach the filter holder to the brewer outlet (A18) (fig. 19).
    Please note: Coffee left on the edges of the filter after pressing does not in any way compromise the quality of the brewing and therefore the end result.

The “perfect dose”

  • A reference mark inside the coffee filters identifies the perfect quantity.De Longhi EC935X Coffee Maker - perfect dose– Laser marked filters: the perfect quantity corresponds to the top line of the mark.
    – Filters with relief mark: the perfect quantity corresponds to the line in relief.

  • Make sure the coffee is at the right level after tamping. It might be necessary to adjust the level a few times using the dial (B2) before the ideal dosage is achieved.

  • If the coffee is extracted too strongly or too weakly even at the ideal dosage, this can be corrected by grinding the beans more finely or more coarsely (see “4.1 Step 1 – Grinding”).
    To correct over-extraction (coffee released too slowly), select a coarser setting.
    To correct under-extraction (coffee released too quickly), select a finer setting.

  • Barista tips: Draw the filter holder away from the tamper with the lever (A20) still down, so that the dose of coffee has a perfectly smooth finish.

  • When using pre-ground coffee:
    – spoon the pre-ground coffee into the filter;
    – turn the dial to ;
    – attach the filter holder to the grinder outlet;
    – lower the tamping lever.

4.3 Step 3 – Brewing

  1. Select the temperature (fig. 20) (see “Coffee preparation temperature”).
  2. Select the desired beverage (fig. 21).
  3. Press OK (B5) to start brewing (fig. 11) (pre-infusion and infusion). Delivery of the coffee will stop automatically.

Coffee preparation temperature
The water temperature is controlled during the entire preparation process to ensure its stability during the extraction step.
The Specialista Prestigio offers 3 infusion temperatures* set in a range between 92 and 96 °C.
The temperature effectively utilized will depend typically on the variety of been and the roast:
Robusta beans require a lower temperature, and Arabica beans a higher temperature.
The same applies for dark roasted beans or for light roasted beans, respectively.

Temperature level Corresponding indicator light Roast colour
MIN Dark
MED Medium-dark
MAX Light – Medium
  • This is the temperature of the water in the thermoblock.
    It is therefore not the temperature of the beverage in the cup or the temperature of the beverage at the moment of release from the outlets of the filter holder.

MAKING MILK BEVERAGES

5.1 Frothing the milk

  1. Fill the jug (C10) with the amount of milk to be warmed/frothed, bearing in mind that the volume of the milk will increase 2- or 3-fold (fig. 22). For a denser and more evenly distributed froth, best results will be achieved using whole cow’s milk at refrigerator temperature (about 5 °C).De Longhi EC935X Coffee Maker - refrigerator temperature
  2. To froth the milk, offer the nozzle of the steam wand (A6) to the surface of the liquid: this will allow air to mix with the milk and steam.
  3. Keep the steam nozzle just in contact with the surface, taking care not to let in too much air and create unsuitably large bubbles.
  4. Immerse the nozzle just beneath the surface of the milk: this will create a vortex in the liquid. Once the milk is heated to the desired temperature, turn off the steam and wait for the flow to stop completely before removing the milk jug from the machine.

Barista tips:

  • Fresh milk is best. Always use fresh milk straight from the fridge.
  • For best results, always replace the milk jug in the fridge when not in use.
  • Whole milk ensures optimum results. The appearance and texture of froth depending on the nature of the dairy milk or vegetable beverages utilized.
  • After frothing the milk, eliminate unwanted bubbles by swirling the jug gently.

Cleaning the steam wand:

  1. Following use, always wipe the steam wand (fig. 23) with a cloth to remove residual deposits of milk. The recommended procedure for in-depth cleaning is to use Eco MultiClean: this product ensures maximum hygiene by removing milk proteins and fats, and can be used for cleaning the entire machine.
  2. Release steam for a few seconds to clean the wand (fig. 12).
  3. Wait until the steam wand has cooled down: to ensure the wand works efficiently over time, use the special cleaning tool (C11) to free the 3 holes (fig. 24) of any obstruction.

CUSTOMISING THE QUANTITY OF COFFEE BEVERAGES WITH THE BUTTON (B7)

  1. Prepare the appliance to deliver 1 or 2 cups of the coffee beverage you want to make, as far as attaching the filter holder (C1) complete with the (C2) or (C3) filter and  ground coffee.

  2. Turn the dial (B8) to select the beverage being programmed.

  3. Press the button: the light associated with the button blinks.

  4. Press the OK button to start delivery. The lights associated with the Ok and buttons blink.
