Putting the coffee maker into operation
The correct sequence of actions when starting a carob coffee maker De'Longhi directly affects the quality of extraction and the taste of the finished drink. Before turning on for the first time, you must make sure that the water tank is filled with fresh filtered liquid, and that the device itself is connected to a working electrical network with grounding. Ignoring the preheating step causes the cold metal elements to take heat away from the water, resulting in sour and under-extracted espresso.
To begin work, turn the main switch located on the front panel or side of the case to the position I or ON. The power indicator will light up to indicate that power is supplied, but the device is not yet ready to brew. The system must heat the thermoblock or boiler to operating temperature, which usually takes from 30 seconds to 2 minutes depending on the specific model, be it compact EC685 or more powerful series Dedica.
The readiness of the device will be indicated by a flashing or constantly lit steam/coffee indicator, the color of which depends on the modification. At this point, it is recommended to open the steam tap for a few seconds to remove condensation and ensure that liquid flows freely through the group. Only after the temperature has stabilized can you begin to prepare a coffee tablet, since using a cold holder critically reduces the brewing temperature.
Preparing the coffee tablet and holder
The quality of espresso depends 90% on the preparation of the coffee base, so maximum attention is paid to the choice of grind and its distribution in the filter. For carob coffee makers De'Longhi The optimal grind is espresso level, which has a consistency similar to fine salt or powder. If the particles are too large, the water will pass through the coffee too quickly, producing a watery drink, and if the grind is too fine, it can clog the filter, creating excess pressure.
Use the included measuring spoon or a kitchen scale to measure. For a single filter, the standard is 7-9 grams of ground coffee, for a double filter - 14-18 grams. Pour the coffee into the holder without a large pile, then carefully distribute the powder with your finger or a special spreader to avoid voids. The uniformity of the layer guarantees the same speed of water passage through the entire area of the tablet.
The next critical step is tempering, that is, compacting the coffee in the filter. Take the tamper with the flat base facing down and place it flat on the surface of the coffee powder. Using a force of approximately 10-15 kg (or just the weight of the body), press vertically down, then lightly rotate the tamper to polish the surface. Tempering must be done strictly perpendicular to avoid tablet distortion, which will lead to a channel effect when water follows the path of least resistance.
⚠️ Attention: Never leave coffee in the holder after preparation. A humid environment promotes oxidation of residues and mold, and makes it difficult to clean the filter in the future.
After compaction, the surface of the coffee tablet should be smooth, dry and dense. If drops of water appear on the surface or cracks are visible, the dosing and tempering procedure should be repeated. A properly prepared filter is inserted into the group with a slight turn until there is a characteristic click or stop, after which the brewing process immediately starts so that the coffee does not start to burn from the heat of the group.
Espresso brewing process
Direct preparation of the drink begins with placing the heated cup on the tray and placing the holder in the brewing group. Make sure that the holder's spout is aimed exactly at the center of the cup so that the stream does not splash around the edges. Pressing the espresso button releases hot water at 9 bar pressure, which is the standard for achieving the perfect crema crema.
The extraction time for a double shot of espresso should be between 20 and 30 seconds. In the first seconds, a thick dark liquid should drip from the spout, which then turns into a uniform stream, reminiscent of a “mouse tail” in viscosity. If the stream flows immediately in a powerful stream, it means that the grind is too coarse or poorly compressed. If the coffee only drips or stops flowing after 10 seconds, the grind is too fine.
Modern models De'Longhi often equipped with an automatic flow stop function, but classic models require manual control. Observe the color of the stream: when it begins to lighten and become transparent, the extraction is complete and the button should be turned off, even if the volume of the drink seems insufficient. Further supply of water will only dilute the drink with bitterness and excess tannins without adding flavoring substances.
The finished espresso should have a dense golden brown foam covering the entire surface of the drink. This foam is a sign of fresh coffee and correct pressure in the system. Immediately after preparation, the holder should be removed and the used tablet should be thrown away. Coffee tablet after proper extraction it should be dry and retain its filter shape when knocked out.
Making cappuccino and frothing milk
For lovers of dairy drinks, a carob coffee maker De'Longhi offers the function of steam supply through a cappuccino maker. Before starting the process, you must switch the operating mode of the device from coffee preparation to steam supply by turning the corresponding knob or pressing the button with the image of a cloud of steam. The steam ready light will illuminate once the system has reheated to a higher temperature.
Use cold milk with a fat content of 3.2-3.5% to obtain a dense and sweet foam. Pour the milk into the pitcher (metal jug) about one-third full, as it will increase in size as you froth. Place the spout of the cappuccino maker just below the surface of the milk and open the tap. The air should be sucked in with a characteristic hissing sound, creating a vortex that stretches the protein bonds and creates microfoam.
- 🥛 Hold the pitcher at an angle to create a swirl of milk inside the jug.
- 🌡️ Control the temperature with your hand: when the pitcher wall becomes hot (about 60-65°C), the steam supply should be stopped.
- 💨 Immediately after use, blow out the cappuccino maker with a short pulse of steam to clear the spout of milk residues.
It is important not to overheat the milk, as at temperatures above 70°C the proteins are destroyed, the foam settles, and the taste becomes less sweet and takes on a boiling taste. After whipping, the pitcher should be immediately wiped with a damp cloth to remove dried milk. Cappuccino maker requires careful care, otherwise the milk fat will harden and clog the holes, which will lead to breakage of the unit.
For the perfect cappuccino texture, use freshly opened cold milk and a pre-chilled pitcher.
There are models with automatic cappuccino maker Cappuccino System, where milk is sucked through a tube from the bag. In such devices, it is important to keep the tube clean and regularly flush the system in self-cleaning mode to avoid milk souring inside the hoses.
Troubleshooting table: and solutions
During operation, users may encounter various situations that require prompt intervention. Below is a table with the most common symptoms of malfunctions and methods for eliminating them, which will help you avoid calling a technician for simple cases.
| Symptom | Probable Cause | Solution |
|---|---|---|
| Coffee flows too fast | Coarse grinding or low tempering | Reduce grinding or increase pressure with tamper |
| Water drips drop by drop | Coffee grind too fine | Increase the grind size |
| The indicator flashes quickly | Decalcification required | Carry out the descaling procedure |
| The steam comes out weakly or with water | Underheating or condensation in the tube | Wait for heating or blow off steam for 5 seconds |
| Water flows from under the holder | Wear of the sealing rubber | Replace group o-ring |
If after performing the recommended actions the problem persists, it may be due to a technical malfunction of the pump, heating element or electronic control unit. In such cases, self-repair may lead to loss of warranty, so it is advisable to contact an authorized service center De'Longhi.
Regular descaling is the only way to prolong the life of your coffee maker's heating element.
Care, cleaning and decalcification
Regular maintenance is the key to a long service life of the coffee maker and consistent coffee taste. Every day after use, it is necessary to rinse the holder and filter with hot water, removing coffee oils, which over time oxidize and give a bitter taste. You should also wipe the external surfaces with a damp cloth, avoiding the use of abrasive detergents.
One of the most important processes is decalcification. Hard water causes scale to form inside the thermoblock and tubes, which reduces heating efficiency and can completely block the passage of water. A signal for the need for a procedure is a flashing indicator or the appearance of a characteristic noise during pump operation. To clean, use special liquid decalcifiers or tablets, diluting them in the proportion specified in the instructions for the specific model.
⚠️ Attention: Never use vinegar or citric acid to descale coffee makers De'Longhi. Aggressive acids can damage the internal seals and aluminum elements of the boiler.
The cleaning process usually takes about 30 minutes and involves running the solution through the system, pausing to dissolve the deposits, and rinsing repeatedly with clean water. Some models have an automatic cleaning cycle that is launched by a combination of buttons, while others require manual switching of modes. After the cycle is complete, be sure to run clean water through the system several times to remove any remaining cleaning agent.
☑️ Daily care of the coffee maker
Frequently asked questions (FAQ)
How often should the water in the tank be changed?
It is recommended to change the water in the reservoir daily, even if the coffee maker has been used little. Stagnant water loses its taste and can become a breeding ground for bacteria. Use only filtered or bottled water of medium hardness.
Can I use ground coffee from a store in a capsule coffee maker?
Standard carob coffee makers De'Longhi work with ground coffee. However, if you have a model with E.S.E. (capsules), then to use ground coffee you will need a special adapter or adapter, which is often included. Without it, brewing loose coffee is impossible.
Why does the coffee maker make noise when working?
A characteristic hum is produced by a vibration pump, which creates the required pressure of 9 bar. This is normal for carob coffee makers. However, if the noise has become significantly louder, or a creaking or knocking noise has appeared, this may indicate wear on the pump or an air lock in the system.
How to properly store a coffee maker if I'm going away for a week?
Before a long absence, it is necessary to empty the water tank, remove and dry the holder, and also disconnect the device from the mains. This will prevent the appearance of unpleasant odors and the development of microorganisms in a humid environment.
What to do if coffee leaks out from under the holder?
Most often, this indicates that the edge of the holder or the sealing ring of the group is contaminated with coffee residues. Carefully wipe the rubber seal inside the group and the edge of the holder. If the problem persists, the rubber may have worn out and needs to be replaced.
