Question 1

How do I descale my DELONGHI Dinamica ECAM353.15.B coffee machine?

Accepted Answer

Your DELONGHI Dinamica ECAM353.15.B has an automatic descaling program. Here’s how to proceed:

Prepare a solution of official De'Longhi descaler (or a compatible product approved by the brand) and pour it into the water tank
Select the 'Descaling' option from the machine's menu
Follow the instructions displayed on your machine's LCD screen - it’s fully automated
The process takes about 20 minutes. During this time, you will need to empty the drip tray if necessary

Be sure to use the original De'Longhi descaler or a compatible product to maintain the proper functioning of your machine and ensure the quality of the coffee. This maintenance operation is essential to keep your device's performance.

Question 2

How to clean the coffee grinder of the DELONGHI La Specialista Arte EC9155.MB?

Accepted Answer

Here’s how to maintain the coffee grinder of your DELONGHI La Specialista Arte EC9155.MB:

Regular cleaning

Use the C9 brush provided with your machine to clean the grinder's catch area
Clean the coffee chute with the same brush to remove residues and prevent blockages

Regular cleaning of the grinder and its surroundings ensures a consistent grind and prevents the buildup of coffee powder that can affect performance.

In case of blockage

If the grinder stops working, turn the grind selector (A2) to position 8 and vacuum all the beans to clear the mechanism.

Replacing the burrs

The burrs of the grinder wear out naturally over time. When they are too worn, contact a De'Longhi service center for professional replacement and recalibration.

Question 3

Turn the doser funnel counterclockwise until it unlocks from the portafilter
Pull upwards to detach it completely

This operation is easily done after tamping the ground coffee. The doser funnel locks in place by rotating clockwise during installation (after inserting the filter into the portafilter), and is removed by the same reverse action.

Question 5

The touch buttons turn on and off randomly

Accepted Answer

If the touch buttons on the control panel (B1, B2, B3, B4) are activating and deactivating randomly, here are the solutions to try in this order:

1. Clean the touch panel

This is the most common cause. Your machine has a touch panel that can become sensitive to dust, moisture, or limescale deposits:

Turn off the machine by pressing the ON/STANDBY button (B1)
Wait a few minutes for the machine to cool down
Gently wipe the control panel and the TFT screen with a soft, non-abrasive cloth (microfiber ideally)
Pay extra attention to the areas between the buttons where dirt accumulates
Do not use water, chemicals, or abrasive sponges

2. Check the power supply

A weak electrical contact can cause this chaotic behavior:

Completely unplug the machine
Wait 30 seconds
Plug it back in and turn it on
Check that the power cable is not damaged

3. If the problem persists

If after cleaning and restarting the buttons continue to activate randomly, it is likely an electronic fault in the touch panel or the control circuit. The manual does not indicate a specific reset function for this type of problem. Contact De'Longhi customer service or an authorized technician for an accurate diagnosis - do not attempt to repair the electronic components yourself.

Question 6

Which button should I use to confirm and finalize an action on the Magnifica Evo ECAM290.61.SB?

Accepted Answer

The confirmation and finalization button depends on the action you are performing:

For general settings (beans, grind, ground coffee): use the B3 button (ground coffee symbol). This button allows you to select your option, then press again to confirm and finalize your choice.
For water filter settings: the B6 button (milk jug cleaning) manages the confirmation of the installation of the built-in water softener filter. Once activated, this button blinks quickly to indicate that the action requires confirmation.
Confirmation status: after pressing the confirmation button, a LED light turns on to indicate that the function is available, that an action is required (fast blinking), or that the function is in progress (slow blinking).

In summary, the B3 button is generally your main confirmation button for the machine's current settings.

Question 7

Can you heat or froth milk without making coffee with the Nespresso Lattissima One?

Accepted Answer

Yes, absolutely. The Nespresso Lattissima One allows you to heat or froth milk independently, without making coffee.

Here’s how to proceed:

Fill the milk reservoir with 125 ml of cold milk (skimmed or semi-skimmed, ideally at around 4°C for optimal froth)
Position a cup under the milk spout
Press the milk button without inserting any Nespresso capsule
The system will dispense hot milk or froth according to your preferences

This function is convenient for preparing drinks with heated milk, or simply to have hot milk to add to other beverages. The components of the milk system are detachable and dishwasher compatible (top rack) for easy cleaning.

Question 8

The red light is on but the machine is not heating: how to fix it?

Accepted Answer

If the red light on your DELONGHI ICM 15210 is on but the machine is not heating, here are the possible causes and solutions:

1. Check the water level

Make sure that the water tank (capacity 1.25L) contains enough water. Check the water level indicator on the side of the tank. If the level is too low, the machine cannot heat properly and the heating element will not activate.

2. Descaling needed

A buildup of limescale can block the heating. The manual recommends descaling every 60 cycles using a commercial descaler. Significant buildup slows down or stops the circulation of hot water. Perform a complete descaling by following the instructions in the manual.

3. Check the power supply

The red light indicates that the device is powered (900W, 220-240V), but this does not guarantee that the heating element is working. Make sure that:

The wall outlet is active (test it with another device)
The power cord is not damaged
Unplug the device for a few minutes, then plug it back in to reset the system

4. Hot plate issue

If after the previous steps the heating does not resume, the hot plate or the internal heating element may be faulty. In this case, the device will need to be checked by a technician or replaced.

Tip: Start with descaling, which resolves 80% of heating issues on this model.

Question 9

The red light on my DELONGHI ICM 15210 is on but the coffee maker is not heating up

Accepted Answer

If the ON/OFF switch light is on but the machine is not producing heat, here are the main causes and solutions:

1. Priority descaling

Limescale buildup is the most common cause. It blocks the heating ducts and prevents hot water from circulating properly. Perform descaling using a specialized descaling product for coffee makers, then run several tanks of clear water through the machine to rinse thoroughly.

2. Check the heating plate

The heating plate (element G of the coffee maker) should keep the coffee warm when the ON/OFF button remains pressed after brewing. Place a full carafe on the plate - it should become warm within a few minutes.

3. Insufficient water

Ensure that the water reservoir is filled to the desired level. An insufficient amount prevents the normal heating cycle from starting.

4. Blocked heating circuit

If complete descaling (with at least 3 rinse water tanks) does not improve the situation, the internal heating element may be faulty and requires professional technical intervention.

Tip: Regular descaling every 2-3 months extends the lifespan of your ICM 15210 and prevents this type of problem.

Question 10

How to adjust the strength and intensity of coffee on the DeLonghi BCO 264 EX:C?

Accepted Answer

On your DeLonghi BCO 264 EX:C, the strength setting of the coffee depends on the type of coffee you are preparing.

Filter Coffee - Flavor Selector

Turn the flavor selector (Flavour System, fig. 12) to adjust the intensity:

STRONG Position: coffee with intense and pronounced aroma
LIGHT Position: coffee with a light aroma

The system adjusts the brewing time to modify the intensity of the aroma without changing the fundamental taste of the coffee.

Espresso - Control by Quantity and Compression

There is no dedicated button for espresso strength. The intensity is controlled manually:

Amount of ground coffee: use about 7 grams (one scoop) per cup
Coffee compression: press firmly and evenly with the coffee press. Proper compression is essential for a good espresso
Grind fineness: use finely ground coffee, specifically recommended for espresso machines

The stronger the compression, the more pronounced the intensity will be. Adjust these parameters according to your personal preferences.
