Coffee machines Philips series Saeco and Philips They are famous for their reliability, but even the most advanced mechanism is powerless in the face of hard water. Over time, a hard limescale deposit forms on the inner walls of the heating element, boiler and tubes, which significantly reduces heating efficiency and can lead to breakdown of expensive equipment. If you notice that the device begins to heat up longer than usual, makes noise during operation, or, even worse, the indicator lights up CALC CLEAN, which means it’s time to carry out the decalcification procedure.
Many owners mistakenly believe that it is enough to simply run water through the system, however descaling requires the use of special acid solutions that can break down carbonate deposits. Ignoring this procedure leads to the fact that the scale peels off in large pieces and clogs the narrow water supply channels, which can lead to failure of the pump or brewing unit. In this article we will analyze in detail the entire service process so that your Philips once again pleased you with the perfect espresso.
Understanding how the cleaning system works will help you avoid common mistakes. In modern models Philips and Saeco The process is often automated, but physical user involvement is critical during the preparation and final rinsing stages. Water hardness directly affects the frequency of these procedures, and if you live in a region with high salt concentrations, you will have to do this more often.
⚠️ Attention: Never use acetic acid or lemon juice to descale Philips coffee machines. Aggressive organic acids can damage rubber seals and plastic parts inside the hydraulic system, and also leave a persistent unpleasant odor that will be transferred to the drink.
Signs of Cleaning and Preparation
The first and most obvious signal about the need for a procedure is a flashing or constantly lit indicator on the control panel. Depending on the model, this may be the inscription CALC CLEAN, DESCALE or a flashing drop symbol. However, you shouldn’t rely only on electronics: if you haven’t carried out maintenance for a long time, and the machine starts to run quieter or the coffee stream has become weaker, these are sure signs that scale already interferes with normal water circulation.
Preparation for the process takes no more than 5 minutes, but requires the availability of certain materials. You will need a branded descaling agent or a high-quality equivalent designed for food equipment. Also prepare a container for collecting liquid with a volume of at least 1.5 liters, since the process involves repeatedly passing the solution and clean water through the system. Don't forget to extract brewing unit before starting the procedure, if the design of your model allows it.
Use only filtered or bottled water when making coffee - this will significantly reduce the rate of scale formation and extend the intervals between services.
It is important to ensure that the coffee machine is placed firmly on a level surface next to the sink. The process can be noisy, and also involve emissions of steam and hot water, so it is better not to place the device in a narrow cabinet or under wall shelves. Make sure that the drip tray is empty and the pulp container is empty so that nothing interferes with the installation of the large drainage container.
- 🧴 Special product for decalcification (liquid or tablets).
- 💧 Water container with a minimum volume of 1.5–2 liters.
- 🗑️ Large bowl or bucket for collecting waste liquid.
- 🧽 Soft fabric for wiping external elements.
Selecting a descaling product
The market offers many solutions, but for technology Philips and Saeco the optimal choice remains original fluids, such as Philips CA6700 or Saeco Decalcifier. These products are developed taking into account the materials used in specific models of coffee machines and are guaranteed not to harm thermoblock or plastic tubes. The concentration of active substances in them is selected so as to effectively dissolve calcium without requiring prolonged soaking.
If the original product is not available, you can use universal liquids for coffee machines that are labeled “suitable for all types of coffee machines.” The main requirement is the absence of chlorine and phosphates in the composition. The use of aggressive chemicals intended for kettles or washing machines is strictly prohibited, as they can cause corrosion of the metal parts of the boiler.
Can I use descale tablets?
Yes, you can, if they are designed for coffee machines. The tablet must be completely dissolved in water of the specified proportion (usually 1 tablet per 0.5–1 liter of water) before pouring into the tank. Do not place dry tablets directly into the tank.
The consumption of the product depends on the degree of contamination and the volume of the tank. The standard procedure usually requires diluting 100-125 ml of concentrate in water to the maximum level. There is no point in saving on the solution: too weak a concentration will not penetrate the dense layer of deposits, and the procedure will have to be repeated, wasting time and resources.
| Product type | Benefits | Features of application |
|---|---|---|
| Original Philips fluid | Guaranteed safety, optimal formula | Follow the instructions on the package exactly |
| Universal liquid | Availability, often cheaper than the original | Check the composition for the absence of chlorine |
| Tablets for decalcification | Easy dosing, long shelf life | Requires time to completely dissolve |
Automatic cleaning program (for models with display)
Modern coffee machines Philips series LatteGo, Xelsis and newer models Saeco equipped with an intelligent cleaning system. To start the process, you usually need to press and hold the clean button for a few seconds until the corresponding light flashes. The machine itself will tell you when to add the product and when to add clean water.
During the program, the machine will alternately dispense the solution and pause. This is necessary so that the active substance has time to act on heating element. During a pause, a characteristic hum of the pump or clicking of valves may be heard - this is a normal operating process that does not need to be interfered with.
☑️ Automatic cleaning algorithm
It is important not to interrupt the process until it is completely completed. If you turn off the machine in the middle of a cycle, the program may reset and you will have to start all over again, or there will be an aggressive solution left in the system that will get into the coffee the next time you turn it on. Follow the display: it clearly shows the current stage - “Add product”, “Rinse”, “Ready”.
After completing the main chemical cycle, the machine will definitely require a rinse cycle with clean water. This is a critical step that removes residual acid from the internal channels. Neglecting this step will result in your first morning coffee having an unpleasant sour taste.
Manual cleaning for models without display
For simpler models such as Philips HD74xx or old Saeco, the procedure may look different. The method of pumping the solution through a cappuccino machine or a special valve is often used here. You will need to prepare the solution in the water tank and start the process of preparing hot water (without coffee), directing the stream into the prepared container.
Drain about half the tank, then turn off the machine and leave it alone for 15 to 20 minutes. This will allow the solution to “soak off” old scale. After a pause, turn on the device and add the rest of the solution, again driving it through the system. This two-step approach provides a deeper clean. hydraulic system in the absence of an automatic timer.
⚠️ Attention: When manually pumping through the cappuccino maker, make sure that hot steam or splashes of acid do not come into contact with the skin of your hands. Keep the spout of the cappuccino maker deeply immersed in the drainage container.
After using a chemical solution, you must thoroughly rinse the tank and run 2-3 full tanks of clean water through the machine. This is standard procedure for all coffee machines, not just Philips. Make sure that the water that comes out has no product odor and foams just like regular tap water.
The key point of manual cleaning is a mandatory pause of 15-20 minutes after draining half of the solution, otherwise the cleaning efficiency will decrease by 50%.
Maintenance of the brewing unit and cappuccino maker
While the machine is busy descaling the internal tubes, it's time to pay attention brewing unit (brew group). Unlike a boiler, it cannot be cleaned with aggressive descaling chemicals. Remove the unit, wash it with warm water without detergents and let it dry naturally. Mechanical cleaning with a brush will help remove residual coffee oils, which also contribute to the formation of jams.
Automatic cappuccino maker LatteGo or pannarello also require attention. Milk fat, when mixed with scale, forms a substance that is difficult to remove. Disassemble the removable parts of the cappuccino maker and soak them in a warm solution of dishwashing detergent or a special milk system cleaner. Use a brush to clean hard-to-reach areas inside the tube.
It is recommended to lubricate the moving parts of the brewing unit with food grade silicone once a year or after each deep cleaning if you feel that the mechanism is moving slowly. However, apply lubricant only to the guides, avoiding the screens and seals that come into contact with the coffee.
- 🚿 Rinse the brewing unit only with warm water, without chemicals.
- 🥛 Clean the milk system with special products for milk.
- 🔧 Lubricate the block guides with food grade silicone once a year.
Frequent errors and troubleshooting
One of the most common mistakes is trying to "cheat" the system by not changing the filter or using a solution that is too weak. The machine may complete the cycle, but there will be no real effect. Also, users often forget to reset the scale counter after the procedure (if this does not happen automatically), and the machine continues to flash the indicator, requiring the action to be repeated.
If after cleaning the machine starts to work louder or leaks appear, this may mean that a large piece of scale has broken off and got stuck in the valve, or, conversely, the scale that previously served as a sealant in microcracks has dissolved. In the first case, repeated washing under pressure may be required, in the second, contacting a service center to replace the seals.
What should I do if the indicator does not go off after cleaning?
Try the procedure again using a double dose of the product. If this does not help, the flow sensor may be dirty or faulty, which requires an electronics diagnosis.
Don't forget that regularity is the key to the long life of your coffee machine. It is better to carry out preventive cleaning once every 2-3 months than to deal with the consequences of a completely overgrown boiler once every two years. Proper maintenance keeps the system pressure and brewing temperature at optimal levels.
How often should I descale my Philips coffee machine?
The frequency depends on the water hardness and intensity of use. On average, it is recommended to carry out the procedure every 2-3 months or after preparing 200-300 cups of coffee. If the water is very hard, the interval is reduced to 1 month.
Is it possible to use citric acid instead of a special product?
The use of citric acid is not recommended by manufacturers. It can crystallize in tight spaces when heated, creating even more serious blockages, and also negatively affects rubber seals.
Why did my coffee turn sour after cleaning?
Most likely, you did not rinse the system thoroughly with clean water after using the decalcifier. Run 1-2 more full tanks of clean water through the machine until the taste returns to normal.
What should I do if the machine does not turn on after cleaning?
Check that the drip tray and pulp container are fully assembled - many Philips models have sensors that block activation if these elements are not installed until they click.
Do I need to lubricate the brewing unit after every cleaning?
No, no lubrication is required after each descaling. You need to lubricate the guides of the brewing unit with food-grade silicone about once a year, or if you notice that the unit has become difficult to move.
