Owners of automatic coffee machines often face a situation when the device ceases to please the perfect espresso. Instead of a dense foam in the cup is watery slurry, and the cooking process itself is accompanied by extraneous noise. Maintenance of the DeLonghi Magnifica coffee machine This is not just a recommendation, but a necessity to preserve the quality of the drink.
Many users mistakenly believe that it is enough to rinse the capuchinator with water. But inside, DeLonghi Magnifica Complex chemical processes occur. Scaling from hard water destroys the heating element, and coffee oils, oxidized, turn into bitter resin, spoiling the taste.
Regular prevention avoids expensive repairs in the service center. In this article, we will discuss in detail all stages of care, from daily hygiene to deep cleaning of the hydraulic system. The interval between full decalcification cycles for Magnifica models should not exceed 2-3 months with an average water hardness.
Daily hygiene and care of the brewing block
The heart of your coffee maker is the brew group. This is where ground coffee is pressed and brewed under high pressure. Daily care of this node is critical to prevent mold and stagnation.
Start every morning by checking the pallet and drip bar. The residues of water in the pallet are an ideal environment for bacteria to multiply. Wash the grille with warm water without using aggressive detergents that can damage the plastic.
- 🧼 Rinse the brewing block daily with warm water without soap to remove the remnants of coffee dust.
- 💧 Change the water in the tank every day, using only fresh, preferably filtered liquid.
- 🗑️ Clean the cake compartment regularly to avoid souring waste.
Once a week, the brewing block should be removed for more thorough inspection. To do this, open the service door and press two red lock buttons. Carefully pull the block over yourself. Do not use force, the mechanism should come out smoothly.
⚠️ Warning: Never attempt to remove the brewing block when the coffee machine is on or on standby. This can cause the plastic drive gears to break down.
After extraction, examine the sealing rings for cracks. If the rubber has lost elasticity, the tightness of the system will be violated, and the machine will give a weak pressure. Wash the block under a stream of warm water, removing all visible contaminants.
The decalcification procedure: the fight against scale
Scale is the main enemy of any technology that comes into contact with water. In the model Magnifica heating element (thermoblock) is made of aluminum and stainless steel. Calcium and magnesium salts settle on the walls, narrowing the passage for water and impairing heat transfer.
When the indicator of the need for decalcification lights up on the panel, it cannot be ignored. The machine blocks the coffee until the procedure is completed. The process will require a special scale or citric acid removal agent, although the manufacturer recommends using original solutions.
The cleaning process takes about 30 minutes and consists of several steps. First, the product is mixed with water in the tank. Then a special mode is started, during which the solution is run through the system. It is important to monitor the fluid level.
☑️ Checklist of decalcination
After passing the cycle with the solution, it is necessary to thoroughly wash the system with clean water. Pour a full tank of fresh water and run the hot water supply through a cappuccinator and espresso display. This will remove the residue of acid, which can give the drink an unpleasant taste.
| Parameter | Recommendation | Consequences of neglect |
|---|---|---|
| Frequency | Every 2-3 months | Clogging of tubes, overheating of TENS |
| Remedy. | Liquid decalcinator | Incomplete dissolution of scale |
| Temperature. | Room (solution) | Damage to plastic elements |
| Washing | 2 full tanks of water | Sour taste of coffee |
Maintenance of the cappuccinator system
If you like a cappuccino or latte, the milk-whipping system requires special attention. Milk fat quickly solidifies and oxidizes, creating ideal conditions for bacteria. In models Magnifica With panarello cleaning is done manually.
Remove the outer nozzle of the panarello. Inside you will find a plastic casing and a metal tube. Take the whole structure apart. Wash all the parts thoroughly with warm water using brush brush. Pay special attention to the hole through which air is sucked.
For models with an automatic LatteCrema, the procedure is simplified but requires discipline. After each use, the milk container must be washed. Many users forget to clean the milk drawer inside the container itself.
- 🥛 Wash the milk container with warm water immediately after use.
- 🌀 Use the Auto Clean function if it is provided by the model.
- 🧊 Keep a container of milk in the refrigerator if there is milk left in it.
⚠️ Please do not leave milk in the system overnight at room temperature. This will lead to souring of the product and the appearance of a persistent unpleasant odor that is difficult to remove.
Once a month, it is recommended to soak the parts of the capcinater in a special solution to remove milk fat. Regular soap may not cope with old deposits. After soaking, rinse the parts thoroughly and reassemble the system back.
Use cold milk (at a temperature of about 4-5 °C) to produce a thicker and more stable foam. Milk fat also affects the result: optimally 2.5-3.5%.
Grinding adjustment and millstone calibration
The quality of espresso depends on the degree of grinding. V DeLonghi Magnifica This is the responsibility of the regulator located inside the grain bunker. Changes are only possible when the coffee grinder is working.
If the coffee leaks out too quickly and the foam is pale, the grinding is too large. The regulator should be turned downwards (numbers 1-3). If the trickle barely drips, and the car buzzes, grinding is too small - twist in the direction of increasing.
It is important to understand that changes do not come into force immediately. Coffee grinder needs to grind 2-3 servings of beans to make new settings appear in the cup. Don’t make sudden movements by the regulator, change the value one division at a time.
Adjustment sequence:1. Turn on the coffee.
2. Remove the grain bunker.
3. Insert the regulator into the millstone hole.
4. Turn one division while the motor is running.
5. Prepare 2-3 cups to check the results.
The grinders in these models are made of steel and are designed for a long service life. However, they become dull with time. If even at the finest grinding, coffee remains watery, it may be time to replace the millstone or conduct a professional sharpening.
Lubrication of mobile mechanisms and seals
Mechanical maintenance is often overlooked, but it is this that prolongs the life of the device. There are many moving parts in the block. Dry friction leads to wear of plastic and the appearance of creak.
For lubrication, use only food silicone lubricants. Conventional engine oil or petroleum petroleum petroleum is not suitable: they can be toxic when in contact with food and break down rubber seals. The lubricant is applied in a thin layer on the guides and axles.
Pay special attention to the sealing ring on the piston of the brewing block. If it is dry, it loses its elasticity faster and starts to pass water under pressure. Easy lubrication with silicone keeps the rubber soft.
How to lubricate rubber seals?
Use only silicone lubricant labeled "Food Grade" or "Food Grade". It is inert, odorless and safe when in contact with hot drinks. Apply the lubricant with a cotton swab in a thin layer.
Check the condition of springs and plastic latches. If you notice a white plaque on the mechanisms, it can be a dried lubricant or lime plaque. In this case, a complete dismantling and cleaning of the node is required.
Diagnostics of common faults
Even with regular care, failures can occur. Understanding the machine signals will help to quickly resolve the problem. DeLonghi Magnifica It is equipped with a self-diagnosis system that indicates a specific node that requires attention.
Often users are faced with a situation where the car is buzzing, but the coffee is not going. This may indicate clogging of the feed nozzle or too small grinding. An air lock in the water supply system is also possible.
- 🔊 Loud noise when working: Check grinding settings or the presence of scale in the pump.
- 💧 Water in the pallet: Possible depressurization of the brewing block or overflow.
- 🚫 Not included: Check the density of the service door closure and the presence of a pallet.
If the indicator of general failure (triangle with exclamation point) lights up, try to restart the machine. Turn it off with the switch, wait 10 seconds and turn it on again. If the error is repeated, a deeper diagnosis is required.
⚠️ Warning: If you hear a thud or metal grinding, turn off the device immediately. Continued work can lead to the destruction of the grinder millstones.
Seasonal storage and conservation
If you plan not to use a coffee machine for a long time (for example, go to the country or on vacation), it must be preserved. Residues of water inside can cause corrosion or mold.
Dump all water from the tank and from the internal system. To do this, you can start the hot water supply cycle without installing a cup until the tubes are empty. Remove the block, wash and dry separately.
Proper preservation of the coffee machine before long downtime ensures that once turned on, it will be immediately ready to work without the need for complex rehabilitation of the hydraulic system.
Keep the device in a dry place, away from direct sunlight. Cover the car with a cloth or return it to the box so that the dust does not get inside. Do not put heavy objects on the coffee machine, it can deform the plastic case.
FAQ: Frequently Asked Questions
How often should I change the water filter?
The water softener filter (if used in your model) requires replacement every 2 months or after 50 liters of water. It depends on the hardness of the water in your area. Timely replacement of the filter significantly reduces the frequency of decalcination.
Can I wash the block in the dishwasher?
Absolutely not. High temperature and aggressive detergents in the dishwasher can deform plastic parts and damage the lubrication of the mechanisms of the brewing unit. Only hand washing with warm water.
Why does coffee flow unevenly in two streams?
This can be caused by uneven distribution of coffee in the brewing chamber or contamination of the nose. Try to increase the degree of grinding or clean the nose of the feed with a brush. Also check if the block is installed smoothly.
Which is better for decalcination: citric acid or special?
The manufacturer recommends special products, as they contain corrosion inhibitors that protect the metal. Citric acid is effective against scale, but when used frequently it can aggressively affect rubber seals and aluminum alloys.
