Appearance of the indicator CLEAN or a specific burning smell during brewing indicates that the internal system DeLonghi Magnifica requires immediate intervention. Ignoring these symptoms leads to clogging of the brewing mechanism with coffee oils and scale, which critically reduces the pump pressure. Owners often notice that the coffee begins to flow in a thin stream or becomes less aromatic precisely because of accumulated deposits in the hydraulic circuit.
Regular maintenance of your automatic coffee machine Magnifica includes not only external wiping, but also deep cleaning of key components. The main enemies of the device are limescale from hard water and oxidized fats from ground grain. A correctly carried out restoration procedure will avoid costly repairs and maintain the taste of drinks at a high level.
Preparation for service and necessary tools
Before starting any manipulations, you must make sure that the device is turned off and disconnected from the power supply. For high-quality work, you will need a special liquid decalcifier designed specifically for coffee equipment, since the use of vinegar or citric acid can damage the rubber seals and plastic tubes inside the housing. Also stock up on a soft, lint-free cloth and a container for collecting waste water with a volume of at least 1.5 liters.
It is important to prepare the workplace in advance, as the process can take from 30 to 60 minutes depending on the degree of contamination. If you use tablets to clean the brewing unit, you should have them on hand, although for models Magnifica Mechanical washing of removable parts is more often recommended. Be sure to ensure that clean drinking water is available for the final rinse of the system.
- 🧴 Liquid decalcifier for coffee machines (necessarily without phosphoric acid).
- 💧 Capacity for draining water up to 2 liters.
- 🧽 Soft brush and microfiber cloth.
- ☕ Tablets for cleaning the brewing unit (optional).
⚠️ Attention: Never use abrasive cleaners, metal sponges or aggressive household chemicals to wash internal parts. This will lead to the formation of microcracks and corrosion of metal elements.
Use only original DeLonghi cleaning products or proven equivalents to maintain your device warranty.
Removing and cleaning the brewing unit
The heart of any automatic coffee machine is the brew group, which is removed through the service door on the side of the body. To begin, open the door and press the red latches on the sides of the mechanism, then carefully pull the unit towards you. Some models Magnifica It may be necessary to press the power button first to lower the mechanism to the down position for removal.
The removed module must be thoroughly rinsed under running water without using detergents. Pay special attention to the mesh filters and moving pistons, where coffee slurry most often accumulates. If a white coating or greasy film is visible on the surface, you can use a soft brush, but rub carefully so as not to damage the Teflon coating.
☑️ Checking the condition of the brewing unit
After water procedures, leave the brewing unit to dry at room temperature, disassembled, if the design allows, or simply in a straightened state. While the parts are drying, wipe the niche inside the case with a damp cloth, removing any spilled coffee. This will prevent mold growth and musty odors in the future.
- 🚿 Rinse the block only with warm water, avoiding boiling water.
- 🚫 Do not use a dishwasher to wash the brewing unit.
- 🔄 Cleaning frequency: at least once a week with active use.
Lubricating the brewing unit
If the pistons move stiffly after drying, apply a thin layer of food grade silicone grease to the rubber seals. This will extend the life of the mechanism.
System decalcification procedure
Scale is the main enemy of the heating element (boiler) and the brewing unit. When the descaling indicator lights up, the machine enters a special mode that cannot be interrupted. Pour the decalcifier solution into the water tank according to the instructions on the product packaging, usually 100 ml of liquid per 1.5 liters of water.
Start the descaling program by following the instructions on the display or the flashing indicators. The device will alternately feed the solution through the cappuccino maker and coffee pot, pausing to dissolve deposits in the tubes. The entire process is automated, but requires your presence to promptly empty the pan and add liquid to the reservoir as needed.
| Process stage | User action | Indication |
|---|---|---|
| Preparation | Pouring solution into the tank | The scale indicator is flashing |
| Flushing 1 | Draining through the cappuccino maker | Steam indicator lights up |
| Flushing 2 | Draining coffee through spout | The coffee indicator is flashing |
| Final | Rinsing with clean water | The lights go out |
Once the chemical cycle is complete, the machine will automatically prompt you to flush the system with clean water. This step is critical as any remaining acid can ruin the taste of the next coffee you make. It is recommended to run a full reservoir of clean water through the system to ensure complete flushing of the reagent.
Caring for the cappuccino maker system
The milk system becomes contaminated the fastest, since milk is an ideal environment for the growth of bacteria. In models Magnifica with an automatic cappuccino maker (card), it is necessary to run the automatic rinsing function after each use. If the model is equipped with a manual pannarello, remove the outer plastic attachment and rinse it under the tap.
To deep clean the milk tube, use a special foaming cleaner or just hot water with a drop of dishwashing detergent, thoroughly rinsing the afterward system. Thin tubes inside the housing also require attention: blow them out with air or use a pipe cleaner if the design allows you to reach the connecting elements.
- 🥛 Rinse the cappuccino maker immediately after preparing milk foam.
- 🌡️ Use warm water to better dissolve milk fat.
- 🔍 Check the integrity of silicone tubes for cracks.
⚠️ Warning: Remaining milk in the system can cause serious food poisoning and unpleasant odors. Never leave milk in tubes overnight.
Cleaning the tray and grinder
Coffee dust and moisture often accumulate in the waste tray, which leads to the formation of mold. Remove the plastic tray and metal grid and wash them thoroughly with detergent. Inspect the waste level sensor (usually a plastic comb or tab inside the recess) and wipe it with a dry cloth, as caked-on coffee may block the full signal.
The coffee grinder requires delicate handling: under no circumstances wet the millstones with water. To clean, use a special dry brush, carefully sweeping the remaining grains out of the chamber. If you hear a noise when grinding, there may be a pebble or very hard grain stuck between the millstones that needs to be removed with tweezers.
Regular dry cleaning of the bean compartment will prevent oxidation of oils on the walls of the container. Wipe the inside with a dry cloth once every two weeks. This is especially important if you are using different types of coffee so that the flavors don't mix.
Dry cleaning of the coffee grinder is the key to uniform grinding and absence of bitterness in the taste of coffee. Water is strictly prohibited here.
Frequent errors and troubleshooting
Sometimes after cleaning the machine may display errors or not work correctly. For example, if the indicator CLEAN does not go out, perhaps the brewing unit is not inserted completely or is skewed. Remove it and reinstall it, making sure that the latches click. The problem may also be in sensors that become contaminated with water during washing.
If the coffee tastes sour after decalcification, the rinse cycle was interrupted or not done thoroughly enough. Repeat the clean water rinsing program one or two more times. In rare cases, it is necessary to reset the settings to factory settings through the service menu, but this should only be done if you have experience.
- ❌ Block insertion error: check the orientation of the handles.
- 💧 Water in the pan: check the drainage hole.
- 🔊 Noise during operation: check for foreign objects in the coffee grinder.
What should I do if the machine does not turn on after cleaning?
Make sure that all parts (tray, drip tray, infuser) are in place. The machine has a security system that blocks activation when services are open. Also check that the infuser is completely dry if you washed it with water - moisture on the contacts can cause a short circuit or blockage.
Can vinegar be used to descale?
Manufacturers categorically do not recommend using vinegar. Acetic acid is aggressive to rubber seals and plastic tubes inside DeLonghi Magnifica. Over time, this leads to loss of elasticity of the rubber bands, leaks and the appearance of an unpleasant vinegar taste in the drink, which is very difficult to wash out.
How often should the brewing unit be lubricated?
Lubrication is not required with every cleaning, but as needed, usually once every 3-6 months or after 3-5 descaling cycles. If the pistons are stiff or squeak, apply food-grade silicone lubricant. Excess grease is also harmful because coffee dust sticks to it.
Why does coffee flow faster after cleaning?
This is normal. Removing scale and coffee oils restores the patency of the channels and pump pressure. If the coffee flows too quickly and without foam, you may need to increase the grind level or compress the tablet more tightly (if using the manual setting).
