Owning an automatic coffee machine doesn't just mean enjoying the perfect espresso every morning, it also comes with the responsibility of regular maintenance. If you notice that taste of coffee has become less saturated, and the stream of steam from the cappuccino maker has weakened, most likely it’s time for deep cleaning. Ignoring these signals can lead to serious damage to expensive equipment.
Model Delonghi Magnifica is famous for its reliability, but, like any complex mechanism, it requires careful attention. Coffee oils accumulate inside the device, which over time oxidize and spoil the aroma of the drink, and limescale deposits also form due to the hardness of the water. In this article, we will analyze each stage of care to ensure that your car lasts for many years.
Timely decalcification and proper hygiene of the brewing unit is the key to stable operation of the pump and heating elements. Don't wait for error indicators to appear on the control panel. Regular maintenance takes a little time, but eliminates costly repairs and ensures that every cup tastes as good as the day you bought it.
Daily maintenance and flushing of the system
Basic coffee machine hygiene starts with simple steps that need to be performed daily. After each drink preparation, the system automatically performs a short rinse cycle. However, this is not enough to completely remove coffee residue. For owners of series models Magnifica It is recommended to manually run the rinsing program, especially if you prepare coffee for different people or use different types of beans.
It is important not to forget about the drip tray and the pulp container. They must be rinsed with warm water without using aggressive detergents. Plastic can absorb odors, so careful drying is required. If wet pulp is left in a container for more than 2-3 days, mold may develop inside the machine, which will negatively affect the hygiene the entire device.
⚠️ Attention: Never try to remove the infuser immediately after turning off the machine. Allow the mechanism to complete the parking cycle, otherwise the plastic drive gears may be damaged.
For daily maintenance, it is also important to wipe the external surfaces with a damp, soft cloth. Drops of milk on the body or cappuccino maker dry out and form a crust that is difficult to remove. This is especially true for models with a metal body, where dirt is obvious. Use only soft cloths to avoid leaving micro-scratches on the surface. Delonghi.
Removing and cleaning the brewing unit
The heart of any automatic coffee machine is the brew group. This is where the magic of turning ground grain into drink happens. Unlike many competitors, Delonghi Magnifica allows this unit to be removed for manual cleaning. This should be done regularly, depending on the intensity of use, on average once every 1-2 weeks.
The extraction process is simple, but requires care. First open the service door, usually located on the left. Press the red tabs on the sides of the block and pull it towards you. Do not use excessive force. If the unit is stuck, it may not be in the correct parking position - turn the car on and off again until the mechanism is in the correct position.
Rinse the brewing unit under running warm water. Strictly prohibited Use detergent, soap or dishwasher. Chemicals can wash away special food grade lubricant from moving parts and damage rubber seals. It is enough to thoroughly wash off the coffee dust and remaining oils with a soft brush.
☑️ Checklist for cleaning the brewing unit
After washing, leave the block to dry at room temperature. Do not use a hair dryer or place it on a radiator, as sudden temperature changes can deform the plastic. While the main unit is drying, wipe the niche inside the machine with a damp cloth, removing any spilled coffee. This will prevent the residue from souring and causing an unpleasant odor.
Decalcification procedure: step-by-step instructions
Scale is the main enemy of heating elements and boilers. Even if you use filtered water, calcium and magnesium salts will build up inside the system over time. Delonghi Magnifica is equipped with an indicator signaling the need for decalcification, but it is better to carry out the procedure preventively, especially in regions with hard water.
For the procedure, you will need a special descaling agent recommended by the manufacturer, or citric acid (although the manufacturer strongly advises using original chemistry). Mix the product with water in the water tank according to the instructions on the package. Typically the proportion is 100 ml of product per 1 liter of water.
Start decalcification mode. On different modifications Magnifica entering this mode is different. Often you need to hold down the steam button or a special key combination when turning it on. During the process, the machine will alternately feed the solution through the boiler and cappuccino maker, pausing to dissolve deposits.
| Stage | Action | Duration |
|---|---|---|
| 1 | Filling the tank with solution | 2 min |
| 2 | Pumping solution through the system | 15-20 min |
| 3 | Rinsing with clean water (3 cycles) | 10 min |
| 4 | Resetting the scale counter | 1 min |
It is important not to interrupt the decalcification process. If you turn off the machine in the middle of a cycle, the program may not end correctly and acid residue may remain inside. After completing the cycle, be sure to flush the system with clean water 2-3 times to remove all traces of the chemical. Only after this can you brew coffee.
Can I use vinegar?
The use of acetic acid is not recommended by the manufacturer. Vinegar has a strong odor that is difficult to clean up and can attack rubber seals and plastic parts of internal tubes, causing them to age prematurely.
Cleaning the cappuccino maker and steam wand
The cappuccino maker requires special attention, since milk is an ideal environment for the growth of bacteria. Dried milk inside the tube creates a plug that interferes with normal steam formation. For models Magnifica With a manual cappuccino maker (pannarello), the cleaning process is quite simple, but requires regularity.
Remove the outer plastic nozzle (panarello). It is usually removed with a slight twist or upward movement. Below it you will see a metal tube. Immediately after use, while the tube is still hot, wipe it with a damp cloth and blow through it with steam for a few seconds. This will remove any remaining milk from the inside.
If the attachment is removable, soak it in warm water and a mild detergent. Clean all openings thoroughly. You can use a brush to deep clean the metal wand, but be careful not to scratch the metal or damage the steam vents.
If steam is weak, check the steam outlet for blockages. Use a fine needle or toothpick to carefully clean out the hole after the machine has cooled completely.
For models with an automatic cappuccino maker (LatteCrema system), the procedure is more complicated. It is necessary to disassemble the milk container and wash all channels. Some models support automatic rinsing of the milk circuit - do not ignore this function. It starts automatically after preparing a milk drink or at the user’s command.
Maintenance of the coffee grinder and doser
The coffee grinder is the first element of the preparation chain. If the grinders are contaminated with old oils, fresh coffee will taste rancid. B Delonghi Magnifica Conical millstones are installed, which do not require sharpening, but do need to be cleaned from oily dust.
To clean the coffee grinder, it is better to use special cleaning tablets or dry rice. Never pour water into the bean compartment! This will cause corrosion of metal parts and damage to electronics. Pour the cleaning agent into the compartment and run a few dry grinding cycles (without brewing) to allow the abrasive to clean the burrs.
Also pay attention to the ground coffee dispenser (workaround). If you use ground coffee, there may be residue in this channel that will harden over time. Clean this channel with a dry soft brush or brush after each use.
⚠️ Attention: Adjusting the grinding degree is only possible while the coffee grinder is running. Turning the adjuster in a static state can break the millstone mechanism.
Service frequency table
To organize the care of your coffee machine, use the following table. It will help you not to miss important points and extend the life of the device.
| Component | Service frequency | Required funds |
|---|---|---|
| Pallet and container | Daily / When filled | Water, soft sponge |
| Brewing unit | 1 time per week | Warm water, brush |
| Cappuccino maker | After each use | Damp cloth, warm water |
| Decalcification | Once every 2-3 months | Descaling agent |
| Coffee grinder | Once every 2-3 months | Cleaning tablets |
Following a maintenance schedule ensures that coffee quality will remain at a high level. Many users forget about the coffee grinder, focusing only on the brewing unit, but it is the old oils in the millstones that often cause a strange aftertaste.
Regular cleaning of all components of the coffee machine saves money on repairs and preserves the taste of the drink throughout the entire service life of the device.
Common mistakes when caring for a coffee machine
Even experienced users sometimes make mistakes that can shorten your life. Delonghi Magnifica. One of the most common is the use of distilled water. Paradoxically, this is harmful for the car. Water hardness sensors in a coffee machine work based on electrical conductivity. Distilled water does not conduct current, and the machine “thinks” that there is no scale, which is why it does not start the decalcification cycle, although scale may form due to other impurities or corrosion.
Another mistake is lubricating the brewing unit with edible oil or petroleum jelly. The moving parts of the unit require a special food-grade silicone-based lubricant, which is not washed off with water and is safe in contact with food. Regular oil will quickly wash away, oxidize and become sticky, causing the mechanism to jam.
You should also not ignore replacing the water filter if your model supports it. Filter AquaClean or similar not only softens water, but also retains mechanical impurities. If you use unfiltered tap water, the risk of heating element failure increases significantly.
What to do if the car is leaking?
If you notice a puddle under the machine, check the tightness of the tray and infusion unit. Often the cause is a clogged drainage tube or an overfilled pulp container. If a visual inspection does not help, the seals may need to be replaced.
Frequently asked questions (FAQ)
How often should the water filter in the tank be changed?
The manufacturer recommends changing the filter every 2 months or after preparing 50 liters of coffee (whichever comes first). If you use bottled soft water, you don’t have to install a filter, but then decalcify more often.
Can the brewing unit be washed in the dishwasher?
No, this is strictly prohibited. High temperatures and aggressive detergents in a dishwasher can deform the plastic parts of the unit and wash away the factory lubricant, which will lead to rapid wear and squeaking.
Why does the coffee machine make noise when working?
Moderate noise is normal for the pump and grinder. However, if the sound becomes louder, or there is a grinding or whistling noise, a foreign object may have entered the grinder, or the brewing unit bearings may need to be lubricated or replaced.
How to reset the decalcification counter if the indicator is on?
After carrying out the complete rinsing procedure with clean water, you need to hold down the corresponding button (often a steam button or a special combination) for 10-15 seconds until the indicator blinks or goes out. The exact combination depends on the specific model Magnifica (ESAM, ECAM).
