Brand coffee machines Saeco are deservedly considered one of the most reliable in their class, however, even the most advanced equipment requires regular maintenance. The main enemy of heating elements and hydraulic systems is limescale, which inevitably forms when using tap water. Correctly selected Saeco descaler can extend the life of the device for years, maintaining the taste of coffee consistently high.
Many owners wonder whether it is possible to use universal cleaners or whether they should trust only original chemistry. In this material we will analyze in detail the chemical composition of decalcinators, consider the features of their effect on various components of the coffee machine and provide a step-by-step algorithm for the cleaning procedure. You will learn why saving on consumables can lead to expensive repairs.
It is important to understand that ignoring the need for descaling will result in reduced boiler performance and poor espresso quality. Scale acts as a heat insulator, causing the heating element to work with overload, which can lead to its burnout. Therefore, timely cleaning is not just a recommendation, but necessary condition operation.
Why is scale dangerous for your Saeco coffee machine?
The water used to make coffee contains dissolved calcium and magnesium salts. When heated, these salts precipitate, forming hard deposits on the inner walls of the tubes, boiler and brewing unit. Over time, the lumen of the channels narrows, which leads to a drop in pressure in the system. For coffee machines Saeco, where pressure is a critical parameter for obtaining quality cream, this becomes fatal.
In addition, scale has low thermal conductivity. When a layer of limescale deposits covers the heating element, it takes more time and energy to heat the water to operating temperature. This not only increases energy consumption, but also creates a risk heating element overheating, which often causes the failure of an expensive unit.
⚠️ Attention: Ignoring the machine’s signals about the need for cleaning can lead to a complete blockage of the hydraulic system. Some models Saeco this causes an error that cannot be reset without service intervention.
Regular use of quality products will dissolve deposits before they harden. The chemical components of modern decalcinators are designed to be aggressive to calcium, but safe for food-grade plastics and rubber seals, which are used in abundance in the construction of coffee machines.
Original Saeco CA6700 and CA6702 products
The manufacturing company develops specialized compounds that are ideally compatible with the materials of its devices. The most popular product is liquid Saeco CA6700. This is a concentrated product that must be diluted with water in a certain proportion before use. One 250ml bottle usually lasts for two cleaning cycles, making it a cost-effective solution for home use.
The second option is tablets Saeco CA6702. They are a compressed powder enclosed in a water-soluble shell. The main advantage of tablets is that there is no need to measure the dosage, which eliminates the human factor. You simply drop the tablet into a reservoir of water and the product is ready to go. This is especially convenient for offices or catering areas.
Both options contain organic acids that effectively break down carbonate compounds. However, it is important to follow the instructions: original products designed taking into account the specifics of the internal sensors of coffee machines Saeco and Philips. Some all-purpose cleaners may contain components that the scale sensor perceives as clean water, stopping the cleaning cycle prematurely.
Keep the opened liquid bottle tightly closed in a dark place. When exposed to air, active components may oxidize and lose their effectiveness.
Alternative remedies and their effectiveness
There are many analogues on the market that are positioned as compatible with technology Saeco. Consumers often choose between brands TopHouse, Filtero or DeLonghi. The main difference lies in the concentration of active substances and the presence of additional additives. Cheap analogues may require more consumption per cycle, which offsets the savings when purchasing.
There is a common misconception that citric acid is a safe and effective substitute. Although it does dissolve limescale, its use in automatic coffee machines absolutely not recommended. Acid crystals can damage plastic pump gears or get stuck in narrow passages, and the high concentration required for cleaning can be harsh on rubber seals.
When choosing an analogue, pay attention to the composition. Products based on sulfamic acid are considered more gentle on metals, but less effective against old scale compared to phosphorus or organic analogues of the original. Always check for compatibility labels with automatic coffee machines.

Instructions: how to decalcify correctly
Cleaning process in machines Saeco is automated, but requires user participation at the preparation and washing stages. Before you begin, make sure the water tank is empty and clean. If you are using a liquid product, mix it with water in a 1:2 ratio, as indicated in the instructions for the specific model. For tablets, simply fill with water and add them.
Start the descaling program via the machine menu. Typically the path looks like this: Menu → Maintenance → Decalcify. The machine will begin pumping solution into the system, pausing to dissolve deposits. At this moment, the pump may be noisy and steam may be released - this is a normal operating process.
☑️ Checklist before launch
After the solution has passed through, the machine will request a rinse. This is a critical step: you need to fill the reservoir with clean water several times and run it through the system to remove any remaining acid. If this is not done carefully, the first coffee you brew will have an unpleasant chemical taste.
⚠️ Attention: Never interrupt the decalcification process by unplugging the machine. This may cause the corrosive solution to remain inside the boiler and damage its walls.
Common mistakes when caring for a coffee machine
One of the most common mistakes is using distilled water. Contrary to expectations, it is harmful for coffee machines Saeco. Scale sensors in such models operate on the principle of electrical conductivity. The distillate does not conduct current, and the machine “thinks” that the tank is empty, or, conversely, does not see water to heat, which can lead to heating element combustion idle.
Another mistake is ignoring water hardness. If you live in an area with very hard water, the standard cleaning interval may not be sufficient. In such cases, it is recommended to use softener filters installed in the tank, or to carry out the decalcification procedure more often, focusing not only on the signals of the machine, but also on the volume of coffee drunk.
Also, users often forget to rinse the brewing unit after decalcification. Chemical fumes and splashes can be deposited on the brewing mechanism, affecting the taste of the drink. Always remove and rinse the brewer with warm water after completing all system flush cycles.
Is it possible to mix different products?
Mixing different chemical formulations (for example, Saeco liquid and tablets of another brand) is strictly prohibited. Reactions between different active components may result in the formation of sediment that will clog the system or the release of hazardous gases.
How often should you clean your coffee machine?
The frequency of the procedure depends on the hardness of the water and the intensity of use of the device. Modern models Saeco (Xsmall, Moltio, Intelia series) are equipped with an intelligent system that automatically calculates the need for cleaning. It takes into account the number of cups prepared and the water temperature.
On average, when using water of medium hardness and preparing 5-10 cups per day, decalcification is carried out once every 2-3 months. If you notice that the coffee has become less hot and the stream of steam from the cappuccino maker has weakened, these are sure signs that scale has already formed and requires removal.
Regular cleaning is more important than the concentration of the product. It is better to carry out the procedure more often with a soft solution than to wait until the canals are completely overgrown.
For office coffee machines that operate non-stop, the intervals are shorter. In such conditions, it is recommended to keep a maintenance log so as not to miss the moment when the filter life or boiler efficiency begins to decline.
Questions and answers (FAQ)
Can I use vinegar to clean Saeco?
No, the use of table vinegar is prohibited by manufacturers. Acetic acid is too aggressive for rubber seals and plastic parts inside the coffee machine. In addition, the smell of vinegar is very difficult to wash out and will linger in the drink for a long time.
What should I do if the machine does not see the descaling agent?
If you use the original product, but the machine does not start the cycle or interrupts it, the sensor may be dirty or out of calibration. Try using distilled water for one rinse cycle (rinse only, no decalcification!) to clean the sensors, and then repeat the procedure with the correct solution. Also make sure that the concentration of the product corresponds to the instructions.
How long does a full cleaning cycle take?
The complete process, including rinsing steps, usually takes between 20 and 40 minutes depending on the coffee machine model Saeco. Do not plan to start the procedure if you urgently need to brew coffee - the machine will be blocked until all stages are completed.
Are chemicals harmful to health if left in the car?
If the final flush is carried out correctly (usually 2-3 full tanks of clean water), the remaining product is completely removed from the system. However, if you notice an off-taste, it is recommended to run another tank of water through the system without coffee.
