Decalcification indicator on the control panel DeLonghi Magnifica Evo It lights up in red, signaling a critical accumulation of lime deposits inside the hydraulic circuit. Ignoring this requirement leads to narrowing of the boiler passageways, increasing pressure in the system and eventual breakage of the heating element. The automatic cleaning mode is designed to run about 400 ml of liquid through the system, which takes about 30 minutes of real time. Procedure requires a special means and a container of at least 1.5 liters for collecting the waste solution.
The process can only be started at rest, when the machine does not brew coffee and is not in washing mode. Before the operation, you need to make sure that there are no residues of liquid in the water tank, and the pallet for drops is completely cleaned. If the device is locked by an error code or flashes the General Anxiety indicator, the root cause of the lock should be eliminated first. Only after returning to the normal waiting mode, the entrance to the service menu becomes available.
It is important to understand that Magnifica Evo It uses an intelligent water hardness calculation system that automatically tracks the number of cups cooked. When using filtered or bottled water, the frequency of maintenance can significantly increase, but it is impossible to completely abandon preventive washing. Regular decalcification Prolongs the life of the pump and preserves the taste of espresso, preventing the appearance of a metallic aftertaste.
Preparation for the procedure for the removal of lime plaque
The efficiency of removing mineral deposits directly depends on the quality of the reagent used and the correct preparation of the equipment. For models DeLonghi series Evo The manufacturer strongly recommends the use of original EcoDecalk products or their qualitative analogues based on lactic or sulfamic acid. The use of acetic acid or lemon juice is strongly discouraged, as these substances can damage rubber seals and plastic elements of the inner highway.
Before mixing the solution, it is necessary to remove the water tank and thoroughly rinse it with warm water, removing possible remnants of the old filter or sediment. In an empty tank is poured 100 ml of decalcination, after which the volume is brought to the mark "A" (0.5 liters) of clean drinking water. The resulting concentrate must be gently stirred, avoiding excessive foaming, which can prematurely trigger fluid level sensors.
⚠️ Warning: Never pour the scale removal product directly into the machine without first diluting it with water in the tank. Concentrated acid can cause chemical burns to internal components and disrupt sensors.
The installation of the tank should be made before the click to ensure tightness of the connection with the water intake pipes. Under the nose of the capuchinator (if it is removable) and under the dispenser for coffee should be put a container of at least 1.5 liters. In the process of cleaning, the machine will discharge water in powerful portions, so high and stable dishes will not work here - it is better to use a wide bowl or pan. It is also recommended to remove and wash the brewing unit, although the cleaning program itself passes through internal channels, bypassing the brewing mechanism.
Use room temperature water to prepare the solution. Cold water will slow the reaction, and hot water can cause excessive foaming when mixed with the active substance.
Starting a cleaning program in the service menu
Interface. Magnifica Evo It is equipped with a touch screen through which navigation is carried out on all system functions. To enter the service mode, press and hold the menu button (three-point icon or gear) for 5 seconds until the list of options appears on the screen. Unlike the previous generational models with mechanical buttons, all actions are confirmed by touching the screen, which makes the process more intuitive.
In the list you need to find the item "Decalcination" (often indicated by an icon with stairs or drops) and confirm the choice. The machine will request proof of readiness: make sure that the reservoir with the solution is installed and the drain tank is set. After pressing the “Start” button, the device will begin pre-training, during which it can turn on the pump several times noisily to fill the highways. A progress indicator will appear on the display showing the current stage of the process.
- 🔹 The system will automatically heat the water to operating temperature to activate the chemical.
- 🔹 The solution will be served in portions through a boiler and a steam tube with pauses to dissolve the deposits.
- 🔹 In the process of work, indicators can flash, and the machine can make various sounds – this is the normal operation of algorithms.
During the execution of the programme decalcination Turn off the device from the network or open the service door. Interrupting the cycle in the middle can cause acid residues to remain in the boiler, which is dangerous for health when further preparation of coffee. If the process is stopped in an emergency, it will have to start again with a full reservoir of new solution. The time to complete the program is usually about 30 minutes, but may vary depending on the degree of pollution and ambient temperature.
Steps of the solution passage and system washing
The cleaning process DeLonghi Magnifica Evo It is divided into several phases, each of which is controlled by electronics. First, the solution is fed into the boiler, where heating and circulation occurs through the heat exchanger. The liquid is then discharged through a steam tube (cappuccinator), clearing it of internal deposits. After that, the washing phase of the water supply circuit in the brewing block follows. The user does not need to switch taps or change modes manually. automation It controls the electromagnetic valves itself.
After the cleaning tank is empty, the machine will sound and request the installation of a tank with clean water. At this stage, the rinse cycle begins. It is necessary to fill the tank with fresh water to the maximum mark "B" (1.7 liters) and return it to its place. The device will start running clean water through the system to wash away the residues of acid and dissolved scale. This stage is critical for the safety and taste of future drinks.
⚠️ Warning: If you feel a sour taste in the first cup after the program is completed, repeat the rinse cycle again. Residues of the product may be invisible visually, but palpable to the taste.
During the rinse phase, the machine can stop several times, creating pauses. This is done so that the water has time to displace the air from the tubes and completely fill all the cavities. Do not try to speed up the process by adding water to the tank on the go - it is better to wait for the cycle to be completed and, if necessary, run an additional rinse through the menu. After the final drain of water, the machine will give a message about the successful completion of the procedure, and the scale indicator will go out.
Technical details of the cycle
The internal timer is reset only after the rinsing phase has been completely passed. If the cycle is interrupted, the counter of the cups until the next cleaning is not reset.
Customization of water hardness and service intervals
One of the key features Magnifica Evo It is possible to fine-tune the water hardness parameter. This allows you to adapt the frequency of reminders of decalcination to real operating conditions. If you use tap water with a high salt content, the machine will request cleaning more often. When using filters DeLonghi Aqua Filter or bottled water intervals are greatly increased.
To change the settings, you need to enter the menu, select "Settings" -> "Water Stiffness". Depending on the region and the quality of tap water, the appropriate level is selected. Included with a coffee machine is often a test strip, allowing you to determine this parameter experimentally. Proper setting not only optimizes the operation of the device, but also prevents false alarms of indicators.
Below is a table of compliance of the levels of stiffness and frequency of service for the model Evo:
| Stiffness level | Indication on the test | Example resource (cups) | Recommended action |
|---|---|---|---|
| 1 (Soft) | No color change. | Up to 300 cups. | Use without filter |
| 2 (Mediocre) | A little pink. | About 200 cups. | Filter is desirable |
| 3 (Tough) | Bright pink/Red | About 100 cups. | Filter is mandatory |
| 4 (Very tough) | Dark red | Less than 60 cups | Distillate/reverse osmosis only |
Installation filter The water in the tank requires activation in the device menu. After installing a new cartridge, you must select the option “Filter Replacement” and confirm the action. The machine will reset the filter resource meter and consider the water soft until the cartridge expires (usually 2 months). This is the most effective way to reduce the frequency of decalcification and improve the taste of coffee.
☑️ Post-cleaning inspection
Common Errors and How to Resolve Them
Even if the instructions are followed, users DeLonghi Magnifica Evo They may encounter unusual situations. Often the problem lies not in the fault of the technique, but in the violation of the sequence of actions or the use of inappropriate materials. Understanding the logic of the device helps to quickly diagnose and eliminate the failure without contacting the service center.
One of the common problems is the inability to run the program. If the start button is inactive or the menu is locked, check if the service door is closed and if the pallet is mounted to the end. Security sensors in the air Evo work clearly: any non-closed element blocks the start of the high pressure pump. Also make sure the machine is not in power saving mode – the screen should be lit brightly.
- 🔸 The machine does not see the tank: wipe the contacts at the bottom of the tank and in the niche of the machine, check the magnetic float.
- 🔸 The process is interrupted in the middle: most likely, the liquid has run out or an air traffic jam has formed in the tubes.
- 🔸 The indicator flashes after cleaning: it is possible that the cycle was not completed completely, a re-start is required.
⚠️ Warning: If after several cleansing attempts, the scale indicator continues to burn and the coffee tastes worse, an air congestion or clog in the narrow boiler channel may have formed. In this case, a professional system upgrade may be required.
Another common situation is the need to replace the filter, although it was installed recently. This is solved by resetting the counter through the menu. If the machine reports a replacement filter, and it is not installed, just ignore this message, but do not forget about decalcification. Electronics DeLonghi It is more important to protect against scale than to the cartridge resource.
The main secret of a long life of a coffee machine is regularity. It is better to prevent more often than to wait for critical contamination, which may require expensive repairs.
Care for external elements after decalcination
After the internal cleaning is completed, attention should be paid to the external nodes that also come into contact with water and dairy products. Cappuccinator Magnifica Evo (especially the LatteCrema version) requires special attention. Although the decalcification program runs the solution through the steam tube, milk fats can remain on the walls of the removable jug or in the steam supply channels.
Remove the removable capuchinator and rinse it with warm water using a mild detergent. Pay attention to the nets and holes – they should not be clogged with dried milk or scale residues. For deep cleaning of the milk circuit in some models there is a separate function "Cleaning system", which is recommended to start after each preparation of milk-based drinks.
The brewing block, although not directly involved in the circulation of water during decalcination, also needs periodic inspection. Remove it, wash it under a stream of water without the use of detergents and let it dry at room temperature. Lubricate the moving parts of the brewing mechanism with food silicone is recommended once every six months or after every 3-4 decalcination to maintain smoothness and reduce noise.
Regular maintenance DeLonghi Magnifica Evo This is not just a requirement of instructions, but a guarantee of stable pressure and the perfect cream on your espresso. Compliance with intervals and the use of quality products will allow the device to serve faithfully for many years, delighting you with aromatic coffee every morning.
Expert council
After a long downtime (more than 2 weeks) before brewing your coffee, start a cleansing rinse program to update the water in the contours.
Can I use citric acid instead of a special remedy?
The use of citric acid is not recommended by the manufacturer. It may not completely dissolve the complex compounds of calcium and magnesium, and can damage plastic seals when incorrectly concentrated. Specialized products contain corrosion inhibitors and surfactants, safe for the foodways of coffee machines.
What to do if the program is over and the indicator is on?
Try to turn the car off the socket for 10-15 minutes, then turn it on again. If the indicator is left, run the decalcination program again, but only with clean water (rinse mode) to make sure that the sensors work correctly. In rare cases, you need to reset the settings to the factory.
How often do I change the water filter in DeLonghi?
The standard filter life is 2 months or 50 liters of water (about 300-400 cups). After this period, the filter stops effectively softening the water, and the machine will automatically switch to calculating the hardness without the filter, increasing the number of requests for decalcification.
Why does the car make more noise than usual during cleaning?
During decalcination, the pump works in intensive mode, pumping liquid under pressure. In addition, air and steam passing through the system can create a characteristic gurgling sound. If the noise is not accompanied by vibration or knocking, this is a variant of the norm.
