How to adjust or increase the water temperature on the DELONGHI CORTINA BCO 250 coffee machine?
Frequently Asked Questions - 31/03/2026
Response Notice-Facile

The DELONGHI CORTINA BCO 250 coffee machine does not offer a direct manual adjustment of the water temperature via a button or specific menu. However, here are some tips to optimize the water temperature when preparing your coffee:

1. Ensure proper preheating of the machine

Before preparing your coffee, let the machine preheat for a few minutes. This allows the boiler to reach the optimal temperature and ensures sufficiently hot water for brewing.

2. Perform a rinsing cycle

After preheating, run a hot water cycle (without coffee) to heat the internal conduits. This prevents the water from losing heat before reaching the cup.

3. Keep the machine clean and descaled

Scaling can reduce heating efficiency. Regularly descale according to your usage frequency and the hardness of your water to ensure optimal temperature.

4. Use fresh, quality water

Use fresh, filtered water to avoid limescale deposits and improve the quality of the coffee as well as thermal performance.

If despite these tips, the water temperature seems insufficient, it may be necessary to seek technical assistance, as the machine does not allow for user adjustment of the temperature.

USING THE ESPRESSO COFFEE-MAKER FOR THE FIRST TIME

Remove the packaging and take out the bag containing the accessories. When the appliance is new, the following accessories must be washed with lukewarm water and detergent then rinsed thoroughly: filter cup, measure, two filters, frothy-coffee disc. The internal circuit of the coffee-maker must then be pre-washed as follows:

Filling the tank

Raise the espresso coffee maker lid (2) and pour fresh water into the tank (fig. 1). For easier filling, the tank can be extracted by pulling upwards (fig. 2). Be careful to reinsert the tank, pressing it to the end.

Pre-wash

  • Plug in at the power socket, remembering the safety instructions.
  • Press the ON/OFF switch (8) and the delivery switch (9). The ON/OFF pilot lamp switches

on (fig. 3). The pump will switch on. Wait until water begins to flow from the boiler nozzle, then press the delivery switch again. After about 2 minutes, the OK pilot lamp will light (fig. 4). This indicates that the boiler has reached the correct temperature.

  • Press the delivery button again for 10/15 seconds, allowing water to flow from the boiler nozzle (fig. 5), then switch off the delivery button.
  • To ensure perfect pre-washing, repeat the above procedure at least five or six times.

The machine is now ready for use.

Positioning the filter holder

To insert the filter holder in the machine, position it under the boiler nozzle (fig. 6). Then push the filter holder upwards and at the same time rotate it towards the right.

HOW TO MAKE A PERFECT ESPRESSO COFFEE

Always use fresh water and keep the tank clean.
- Before making coffee, always wait for the OK pilot lamp to light; this lamp indicates that the water in the boiler has reached the correct temperature for brewing coffee.
- Before making coffee, heat the cups, filter holder, filters and Never Fail Crema system. The accessories can be heated with hot tap water or in the following way:
- Insert the Never Fail Crema system into the filter holder. This device makes it possible for you to get an excellent cup of coffee, no matter what type of powdered coffee you may be using.

Warning: if you wish to use the 2-cup filter, put the "Never Fail Crema" system with the lower projecting parts inserted in the coffee outlet holes of the filter holder cavity (fig. 7). If you wish to use the one-cup filter instead, rotate the "Never Fail Crema" system 1/4 of a turn so that the projecting parts are not inserted inside the coffee outlet holes and in this way the device remains in the high position (fig. 8).

  • Insert the 1- or 2-cup filter in the filter holder and attach the filter holder to the machine as explained above.
  • Place the coffee cups beneath the filter holder.
  • Turn on the machine by pressing the ON/OFF switch (8).
  • Wait for the OK light to come on then press the delivery switch (9) making water come out of

the boiler outlet to warm the filter holder, filter and cups.

  • Press the delivery switch again, then remove and drain the filter holder, the filter and the cups.

We suggest you follow this procedure (delivering hot water without coffee in the filter) after using the machine to produce steam. This brings the machine back to the optimum temperature for making coffee.

Top quality beans, correctly roasted and ground, will always produce the best coffee.

Procedure

  • Switch on the machine by pressing the ON/OFF switch (8) and wait until the OK pilot lamp lights.
  • A few drops of water may escape from the boiler nozzle. This is perfectly normal.
  • Insert the Never Fail Crema system in the filter holder as explained above; then insert the 1- or 2-cup filter.
  • Place 1 or 2 measures of ground coffee in the filter (fig. 9) spreading it evenly and pressing down lightly with the tamper (fig. 10).
  • Attach the filter holder as explained above.
  • Place the pre-warmed cup or cups on the drip tray under the filter holder spouts. When the OK pilot lamp lights, press the delivery switch. When the desired quantity of coffee is obtained (generally 20 - 30 seconds), turn the delivery switch off (fig. 11).
  • Wait a few seconds before detaching the filter holder by turning the handle from right to left.
  • To remove the used coffee grounds, retain the filter in position using the special lever fitted to the handle (fig. 12).
  • If you want to remove the Never Fail Crema system, turn the filter holder face-down and knock the system out. The removal of the Never Fail Crema system must be carried out when the filter is cold.
  • If the machine is not to be used for a long time, turn it off and empty the water tank.

A pre-wash should be performed, as described above, before using it the next time.

MAKING A CAPPUCCINO

  • Use a deep metal container, preferably of small diameter.
  • Do not fill to more than 1/3rd, otherwise the milk may overflow when it boils.

  • Switch the machine on by pressing the "ON/OFF" switch (8).

  • Press the steam switch (10). After about 3 minutes, the OK pilot lamps (9 and 10) lights to indicate that the machine has reached the correct temperature for the generation of steam (fig. 13).
  • When using the steam function, a few drops of water may escape from the nozzle: this is completely normal. However, care should be taken to avoid scalding.
  • Immerse the steam tube deeply into the milk in order to heat it (fig. 14) and turn the steam knob gradually counterclockwise until steam is produced. Adjust the position of the knob to regulate the quantity of steam delivered by the nozzle.
  • over the container until the tube skims the surface of milk, immersing the tube slightly from time to time for a few seconds (fig. 14).
  • If your coffee machine is equipped with a cappuccino nozzle, immerse the nozzle into the milk down to the mark on the "cappuccino" nozzle (fig. 15).

For a few moments, the steam will come out mixed together with a little water. In order to obtain drier steam, hold the steam knob open for a few seconds.

  • Immediately after use, unscrew and rinse the cappuccino nozzle to remove any milk deposit (fig. 16).
    From time to time, use a pin to clean the holes in the cappuccino nozzle (fig. 17).

WARNING: Whenever you make use of the steam function, first be certain that there is water in the boiler compartment. Do so in the following way:

1) Make sure that there is water inside the removable tank (1).
2) Push the ON/OFF (8) and the coffee emission buttons (9). The indicator light for the ON/OFF switch will turn on. The pump will begin to "load up" water.

Wait until water begins to come out of the boiler tap, then turn off the coffee emission switch. Now proceed as you would for the regular use of the steam function.

PRODUCING STEAM

(for heating liquids, such as tea, etc.) Press the ON/OFF switch (8) and the steam switch (10). After a few minutes, the OK pilot lamp (10) lights to indicate that the machine has reached the correct temperature for the selected function (in this case, to make steam).

Immerse the steam nozzle in the liquid to be heated and turn the steam control knob counterclockwise.

Adjust the position of the knob to regulate the quantity of steam delivered by the nozzle.

When the liquid is hot, completely close the steam knob and turn the ON/OFF switch off.

HOT WATER

(to prepare tea, etc.)

  • Switch the machine on by pressing the ON/OFF switch (8) and wait until the OK pilot lamp lights.
  • Place a cup or glass under the steam tube (15).
  • Press the delivery switch (9) and, at the same time, open the steam outlet lever.
  • Hot water will flow from the tube. As soon as the desired quantity of hot water has been obtained, close the lever and press the delivery switch again.
  1. Before using your Drip Coffee Maker for the first time, fill the drip coffee carafe with water to the 10-cup level, and pour into the water reservoir. Follow the instruction below, omitting the paper filter and coffee. This will thoroughly cleanse the unit prior the initial brew of coffee.
  2. Always use fresh, cold tap water to brew coffee.
  3. The Drip Coffee Maker brews a maximum of 10 cups. Never exceed this maximum amount as shown by the markings on the carafe.
  4. Use a fine drip grind coffee - that is recommended for drip coffee makers.
  5. The warming plate heats up when the drip coffee maker is switched ON. Avoid touching it, and never allow the power cord to come into contact with it.
  6. The amount of freshly brewed coffee delivered after the brewing process will always be slightly less than the amount of water poured into the reservoir. This is due to the absorption of some water by the ground coffee. Therefore put in a little more water to begin with.

HOW TO MAKE DRIP AND/OR BARLEY COFFEE

  1. Remove the carafe from the recessed warming plate. Grasp the handle, lift it up, slide the carafe straight out. Open the lid, and fill the carafe with cold water to the desired level (fig. 18).
  2. Open the drip coffee reservoir cover, and pour the water into the reservoir (5) (fig. 19). Close the lid of the carafe and place carafe on warming plate.
  3. Turn the drip coffee water tube (6) to the right (fig. 20).
  4. Place paper filter into the filter holder (fig. 21) or permanent filter (if provided). We recommend 1 × 4 cone style filters.
  5. Measure coffee into the filter, using the handy measuring spoon provided (fig. 22). Measure slightly less than one level spoon of ground coffee for every cup of water measured into the reservoir. Personal tastes differ. Experiment with varying amounts of coffee, until the desired strength is reached. If you are using the permanent filter and want to make coffe using a blend of barley, chicory and so on, remember to halve the amount of powder (one measuring cup every two cups of coffee) to prevent the coffee from seeping out of the filter. Replace filter holder.
  6. Replace the drip coffee water tube (6) in the centre.
  7. Plug the coffee maker.
  8. Push the ON/OFF drip coffee switch to the ON position (fig. 23). The red light indicates that the machine is operating.
  9. The carafe rests on a warming plate that will keep your coffee at serving temperature. Turn switch to the OFF position if carafe is empty.

During the brewing cycle, the coffee maker will create some steam. This is normal and to be expected.

KEEPING THE COFFEE HOT

The coffee is kept warm on a warming plate which begins to heat up when the drip ON/OFF coffee switch is switched on and will keep the coffe hot until the coffeemaker is switched off.

DRIP-INTRRUPTION FEATURE

This special feature is for the person who can't wait for all of the coffee to be brewed, especially when making 8-10 cups. When carafe is half-filled, remove the carafe and serve. Replace carafe. The flow of coffee into carafe will resume.

To prevent coffee from overflowing from the filter holder during the brewing cycle, the carafe should be immediately returned to the warming-plate after pouring.

CAUTION: If you plan to serve coffee and espresso at the same time, make sure that you start preparing the drip coffee first, which needs a longer time for brewing.

Always be present when the espresso/cappuccino part of the machine is in the ON position. Make sure that the machine is turned OFF immediately after preparing use.

CLEANING AND MAINTENANCE

  • Before carrying out any cleaning operations of the exterior parts, switch the machine off, remove the plug from the socket and leave the machine to cool.
  • Do not use solvents, detergents or abrasive products to clean the machine. A soft damp cloth is sufficient.
  • Clean the filter holder, filters, drip tray, carafe and water reservoir regularly.

  • To remove the drip coffe filter holder, press the filter holder then rotate it leftwards and lift it (fig. 24). When reassembling it, be careful to insert it correctly.

  • To extract the Never Fail Crema system, once the filter has been removed rotate the filter holder and hit it against a plane surface so the device falls out.
  • Do not wash the machine: it is an electrical appliance

DESCALING

It is advisable to de-scale the appliance every 4 - 8 months, depending on the hardness of the water and the frequency of use. De-scale using water and vinegar as follows:

  • Fill the tanks with water, diluting 100cc of vinegar or descending agent in it.
  • Operate the machine as though making the espresso and coffee filter until the tanks has been emptied, then rinse.
  • Repeat the operation with water only for 2-3 tanks, rinsing until there is no longer any smell of vinegar or descending agent

D escaling with other substances may be hazardous to your health.
