Indicator Calc/Clean lights up orange or red, and the device begins to make unusual sounds during operation, which indicates a critical level of deposits inside the hydraulic system. This is a direct signal that it is necessary to immediately start the mode decalcification, otherwise hard water will damage the heating element. Owners of series models Philips Saeco or Philips L'Or Barista the first signs are often ignored, which later results in expensive repairs.
The process of removing mineral salts does not require disassembling the equipment, but strictly requires compliance with the sequence of actions described in the manual. If you skip the rinse step or use the wrong product, a chemical taste will remain in your drink and the rubber seals may become warped. Correct descaling extends the life of the boiler and maintains the pressure in the system at factory levels.
Before starting the procedure, make sure that there is no water in the reservoir and that the drip tray and pulp container are completely empty. You will need an empty container with a capacity of at least 1.5 liters to drain the dirty liquid during the flushing process. It is also worth preparing a clean cloth to wipe the external surfaces, as condensation may splash as steam escapes.
Causes of scale formation and its impact on operation
The main reason for the appearance of solid deposits is the high content of calcium and magnesium salts in tap water. When heating a liquid in thermoblock these salts precipitate, forming a hard coating on the walls of the tubes and heating elements. Over time the layer calcium carbonate thickens, which significantly impairs thermal conductivity and increases the coffee preparation time.
Ignoring the need for cleaning leads to a number of technical malfunctions that can completely damage the device. First of all, the pump suffers, as it has to work with increased load, pushing water through narrowed channels. It is also possible for the system to overheat, since scale acts as a heat insulator, preventing the water temperature from reaching the required values.
⚠️ Attention: Using acetic acid or lemon juice instead of specialized products can damage the internal rubber seals and plastic parts of the system.
Regular maintenance helps avoid the following negative consequences:
- 📉 Reduced pressure in the brewing group, causing the coffee to become watery.
- 🔊 The appearance of loud noise and buzzing when the pump is running.
- 🌡️ Unstable temperature of the finished drink.
- 🚫 Complete blockage of water supply due to clogged valves.
The rate at which deposits form directly depends on the hardness of the water in your area. Some models Philips The hardness level can be adjusted, which allows the device to independently monitor the need for a procedure. If you use bottled or filtered water, the service intervals may be longer.
Necessary cleaning products and tools
To effectively and safely remove mineral deposits, it is recommended to use only certified liquid products, developed specifically for coffee equipment. There are many options on the market, but manufacturers Philips It is recommended to use original solutions, such as CA6700 or their analogues, which are guaranteed not to contain aggressive components. It is not recommended to use powder products, as they may not completely dissolve and clog thin channels.
In addition to the cleaning solution itself, you will need some preparation of the work area. Be sure to find a clear container with a capacity of about 1.5-2 liters to visually control the color of the liquid coming out. You should also have soft, lint-free wipes on hand to wipe the outer panels and spout of the cappuccino maker.
To mix the solution, use only cold water at room temperature. Hot water can activate the chemical reaction prematurely and reduce the effectiveness of the product.
Here is a list of what you need to prepare before starting the cleaning mode:
- 🧴 Specialized descaling agent (decalcinator).
- 💧 Clean drinking water (about 1.5 liters).
- 🥣 Large bowl or pan to collect waste liquid.
- 🧽 Soft fabric for caring for external surfaces.
The product should not contain chlorine, strong acids or abrasive particles. If you cannot find the original solution, choose analogues marked “for automatic coffee machines” and a neutral pH balance.
Preparing the coffee machine for the decalcification process
Before starting an automatic cycle, a number of preparatory steps must be completed to ensure the safety and efficiency of the process. First of all, remove the brewing unit if the design of your model Philips this allows, and rinse it under running water. Although most of the cleaning involves the hydraulic system, having a clean brewing mechanism will prevent old coffee residue from getting into the wash water.
Empty the drip tray and coffee grounds container by rinsing them thoroughly with warm water. Make sure all removable parts are dry before putting them back in place. This will prevent the tray from overflowing during the process, as a large volume of liquid passes through the system during descaling.
☑️ Preparation checklist
Fill the water tank to the mark MAX or according to the instructions for a specific product (usually 500 ml of water and one bottle of solution are required). There is no need to stir the solution inside the tank; the system will do this itself when taking the first portion of liquid. Place a large container under the hot water spout and under the cappuccino maker, if your model has one.
⚠️ Attention: Do not start the process if there is old water left in the tank. Drain it completely so that the concentration of the cleaning agent matches the calculated concentration.
Step-by-step instructions for starting the cleaning mode
The process for activating the cleaning mode may vary slightly depending on the series of your coffee machine Philips or Saeco. In most modern models, you need to press and hold the button with the image of a drop or a special button Calc/Clean within 5 seconds. A corresponding message will appear on the display confirming entry into maintenance mode.
Once activated, the machine will begin pumping solution through the system. The liquid will alternately be supplied through the hot water spout and the cappuccino maker. You do not need to interfere with this process, but you should monitor the level of liquid in the drain container so that it does not overfill. The entire cycle can last from 15 to 20 minutes depending on the model.
Algorithm of actions during automatic washing:
- ⏱️ Wait until the first stage of pumping the solution is completed.
- 💧 Drain the used liquid and rinse the container.
- 🔄 Pour clean water into the tank for the rinsing stage.
- ▶️ Click the start button to continue the process.
What to do if the process is interrupted?
If the power supply is interrupted or the process stops on its own, do not panic. Turn on the machine in normal coffee mode and pour about 100 ml of water through the steam spout to clean the valves. Then repeat the cleaning procedure from the very beginning using a new portion of the solution.
It is important not to forcefully interrupt the process, as this may leave the chemical inside the tubes. If the indicator continues to flash after the cycle has completed, the procedure must be repeated. In some cases it is necessary to perform a double rinse cycle with clean water to completely remove any remaining acid.
End of cycle and final rinse
Once the machine has pumped all the cleaning solution, it will automatically go into rinse mode or ask you to add clean water. This step is critical as it removes any remaining decalcifier from the internal circuits. Neglecting this step will result in your first cups of coffee having an unpleasant chemical aftertaste.
Fill the tank with clean water to the maximum and start the rinse cycle according to the instructions on the display. The machine will run water through the system in the same way as the main cycle. It is recommended to perform at least two full rinse cycles, especially if you used a concentrated product.
| Stage | Action | Liquid volume | Duration |
|---|---|---|---|
| 1. Preparation | Mixing the product | 500 ml + product | 2 min |
| 2. Decalcification | Pumping the solution | 500 ml | 10-15 min |
| 3. Rinse 1 | Washing with water | 1-1.5 liters | 10 min |
| 4. Rinse 2 | Final rinsing | 1-1.5 liters | 10 min |
When all steps are completed, the machine usually beeps or displays a success message. Indicator Calc/Clean should go out or stop flashing, turning green or standard operating mode. Now the device is ready to make coffee, but it is better to pour the first cup into the sink.
Key Point: Complete rinsing is more important than brushing itself. Acid residues corrode seals faster than the scale itself.
Common errors and ways to resolve them
Even following the instructions, users sometimes encounter problems that block the completion of the process. One common mistake is to use water that is too hot to prepare the solution, which can cause excessive foaming and overfilling of the system. As a result, the machine may stop with an error.
If the light does not go off after completing the procedure, there may be air left in the system or a clogged valve. In this case, try running clean water through the steam spout several times in a row in the hot water preparation mode. This will help push out any air pockets and remaining dirt.
Typical problems and methods for solving them:
- ❌ The machine does not enter cleaning mode: Make sure the reservoir is full and the drip tray is installed correctly. Try turning the device off and on.
- 💨 Too much foam: Stop the process, drain the contents, rinse the tank and start again using room temperature water.
- 🔇 No pump sound: Check to see if the intake valve in the tank is clogged. Mechanical cleaning with a needle may be required.
⚠️ Attention: If the error persists after several cleaning attempts, do not disassemble the device yourself. Contact an authorized service center.
Performing this procedure regularly will eliminate most of the problems associated with hard water. Don't wait until the machine stops working - prevention is always cheaper and easier than repair heating element or replacing the pump. Follow the indication and use quality products.
Can I use tablets?
In Philips automatic coffee machines, the use of descaling tablets is not recommended, as they may not have time to dissolve and damage the intake mechanism. Liquid products are preferable.
Questions and answers (FAQ)
How often should I descale my Philips coffee machine?
The frequency depends on the water hardness and intensity of use. On average, the indicator lights up every 2-3 months or after 300 cups have been prepared. If the water is very hard, the procedure should be carried out more often, even if the indicator has not yet come on.
Is it possible to use citric acid instead of a special product?
The manufacturer does not recommend using citric acid, as it can damage the plastic and rubber parts inside the system. In addition, acid crystals may not completely dissolve and clog thin tubes. It is better to use certified liquid decalcifiers.
What should I do if I interrupted the cleaning process in the middle?
If the process was interrupted, an aggressive agent remains in the system. It is necessary to turn on the machine in normal mode and pour several portions of water through the steam spout and cappuccino maker to rinse the circuit. After this, it is recommended to run the full cleaning cycle again.
Why does the scale indicator light up immediately after cleaning?
This may mean that the cycle was not completed completely (for example, a rinse step was skipped) or there is air remaining in the system. Try repeating the procedure, paying special attention to the rinsing step with clean water. If the problem persists, the sensor may be faulty or service may be required.
Does using filtered water affect the frequency of cleaning?
Yes, using high-quality filtered water or reverse osmosis water significantly reduces the rate of scale formation. In this case, the intervals between decalcification procedures may increase, which will extend the life of the heating element and pump.
