Every morning, the scent of freshly ground coffee fills the house. It's a small luxury, a ritual that kicks off the day with the right energy. Your automatic coffee machine is the faithful accomplice of this pleasure, a jewel of technology that transforms simple beans into a unique sensory experience. But like any precision instrument, to work at its best and last over time, it requires constant attention and care. We often underestimate the importance of maintenance, thinking that an occasional rinse is sufficient. The reality, unfortunately, is quite different. Two silent but implacable enemies hide within its circuits: limestone and the oily residues of coffee.
Not only do these opponents compromise the flavor of your espresso, making it bitter and less full-bodied, but they work in the shadows to damage the machine's internal components, leading to malfunctions, blockages and costly repairs. Ignoring signals, such as a slower flow of coffee, a lower temperature or an unusual noise, dramatically shortens the life of your appliance. But don't worry: the solution is easier than you think. Complex technical interventions are not needed, but a regular maintenance routine and the use of products specifically formulated to act effectively and safely. In this complete guide, we will reveal the perfect cleaning protocol, based on the synergistic action of three fundamental products that every owner of an automatic coffee machine should have. Get ready to rediscover the true taste of your coffee and to become a true expert in the care of your precious daily ally.
The Invisible Enemies: Limestone and Coffee Oils
To understand the importance of maintenance, we must first know our opponents. They are not visible to the naked eye, but their effects are devastating both for the palate and for the mechanics of the machine.
Beware of Silent Damage!
Ignoring the formation of limescale and oily residues not only worsens the taste of the coffee, but can cause permanent damage to your machine's boiler, pumps and valves, often voiding the warranty.
1. Limestone: The Silent Killer
Tap water, even the one that seems the purest, naturally contains dissolved minerals such as calcium and magnesium. When the water is heated inside the coffee machine boiler, these minerals precipitate and deposit on the internal surfaces, forming hard and whitish encrustations: limestone. This process is relentless and progressive. Initially, a thin layer of limestone acts as a thermal insulator, forcing the machine to work harder to reach the correct temperature, with a consequent increase in energy consumption. Over time, the incrustations become thicker, narrow the water passages, reduce pressure and can completely clog the thin tubes and the solenoid valve. The result? A coffee brewed slowly, lukewarm, without cream and, in the worst cases, the total shutdown of the machine.
2. Oily Residues: The Aroma Attack
Each coffee bean contains natural oils that define its aroma and body. During the grinding and dispensing process, these oils are deposited in the brewing group, in the outlet spout and at all the coffee's passage points. If not removed regularly, these oily residues oxidize and go rancid in contact with air and heat. This process profoundly alters the aromatic profile of your coffee, introducing unpleasant notes of bitter, burnt and stale, which cover the delicate nuances of your favorite blend. In addition, these deposits can become a breeding ground for the proliferation of mold and bacteria, with obvious health risks. Cleaning with water alone is not enough, as the oils are water repellent and require a specific detergent to be dissolved and eliminated effectively.
The 3-Step Solution: The Trio for Perfect Maintenance
The good news is that fighting these enemies is possible and requires only a simple routine and three extraordinary products that work in perfect synergy. Let's see them in detail.
Step 1: Active Prevention with the Softener Filter
The first and most important step is to act at the source. The De'Longhi Water Filter is your first line of defense. Installed directly in the water tank, it acts as a selective barrier, purifying water before it even enters the machine's circuits. It is not a simple filter, but a sophisticated system that actively improves the quality of water and, consequently, of your coffee.
Immediate Benefits:
- Drastic Limestone Reduction: Its ion exchange resin captures calcium and magnesium ions, responsible for the formation of limestone, protecting the internal components of the machine.
- Aroma enhancement: Thanks to activated carbon, it eliminates chlorine and other impurities that can alter the taste of coffee, ensuring purer water and a cleaner and more intense aroma.
- Less Decalcifications: By constantly using the filter, the need to perform the descaling cycle is significantly reduced, saving you time and money.
- Consistent Performance: It ensures that the machine always works in optimal conditions, maintaining a stable temperature and pressure for a perfect cream every time it is dispensed.
Replace the filter every 2 months or as directed by your machine for continuous protection.

Even with the use of the filter, a minimum amount of limescale may settle over time. When your machine tells you the need for a cleaning cycle, it's time to use heavy artillery, but in an ecological version. The De'Longhi EcoDecalk descaler is the most powerful and safe solution to completely remove the most stubborn limescale deposits accumulated in the boiler and circuits.
Why Choose EcoDecalk:
- Eco-friendly Formula: Made with plant-based lactic acid, it is 100% environmentally friendly and biodegradable. Powerful against limescale, gentle with the environment.
- Tested Effectiveness: Up to 3 times more effective than traditional descaling agents in dissolving limescale deposits, restoring the machine's full efficiency.
- Safe and Guaranteed: Its formula is designed not to be aggressive on the delicate internal components of your De'Longhi machine, preserving its integrity and durability.
- Convenience of Use: The 500 ml package allows you to carry out up to 5 descaling cycles. Simply follow the instructions on your machine's manual for a perfect result.
Step 3: Deep Cleaning with Cleaning Tablets
We protected the machine from limescale, but what happened to the oily residues that harm the taste? This is where the Cleaning Tablets come into play. This product is specifically formulated to dissolve and remove coffee fats and oils that accumulate in the brewing group and in the passage circuits, where the descaler does not reach.
The Secret to an Always Pure Aroma:
- Powerful Degreasing Action: Their active formula dissolves accumulations of rancid coffee, eliminating any bitter and unpleasant aftertaste.
- Improve Flow: By freeing the spouts and filters of the brewing group, they guarantee a fluid and homogeneous delivery, for a thick and persistent cream.
- Assured Hygiene: They remove deposits that can promote the growth of mold and bacteria, ensuring coffee that is not only good, but also hygienically safe.
- Brewing Group Maintenance: A clean group moves better, puts less strain on the engine and lasts longer. Regular use of the pads is critical to the mechanical health of your machine's heart.
Use a tablet once a month or every 200 coffees to keep the brewing group in perfect condition.
