Regular maintenance of the coffee maker is the key not only to a tasty drink, but also to the long life of the device itself. Equipment owners Saeco and Philips often faced with the need to remove limescale and residues of coffee oils, which inevitably accumulate during operation. Ignoring these procedures leads to clogging of the hydraulic system and deterioration in the taste of espresso.
In this article we will look in detail at how to clean a Philips coffee machine from scale and dirt using available means. You will learn how to properly remove and wash the brewing unit, what products are best for decalcification, and why you should not use vinegar. Following these recommendations will help you avoid costly repairs at a service center.
The cleaning process is divided into two main stages: mechanical cleaning of internal components and chemical decalcification of the system. First stage requires physical access to the brewing unit, and second — launching a special washing program. It is important to perform both procedures regularly as they complement each other.
Preparation for cleaning and necessary products
Before starting any work, it is necessary to prepare a workplace and consumables. You will need a container with a volume of at least 1.5 liters to drain the water, a soft sponge, a fluffy brush and, of course, the cleaning agent itself. The use of aggressive chemicals such as chlorine-containing solvents is strictly prohibited, as they can damage the plastic seals.
For decalcification it is best to use the original solution Philips CA6700 or its high-quality analogues based on lactic or citric acid. Never use acetic acid, as it is too aggressive for rubber gaskets and can leave a persistent unpleasant odor that will be felt in the coffee for a long time. The concentration of the solution must strictly comply with the instructions on the bottle.
Also make sure you have access to clean water. It is advisable to use filtered or bottled water to minimize the formation of new scale immediately after the procedure. Preparation takes only a few minutes, but greatly simplifies the entire process.
- 🧼 Original descaling agent or tablet analogue.
- 💧 Clean water (about 1.5–2 liters).
- 🧽 Soft sponge and brush with natural bristles.
- 🥣 Plastic basin or deep bowl for soaking parts.
- 🧤 Latex gloves to protect the skin of your hands from chemicals.
Dismantling and mechanical cleaning of the brewing unit
The heart of any automatic coffee machine is the brew group. This is where the coffee tablet is formed and the hot water is poured out. Over time, coffee oils form on the walls of this unit, which oxidize and give the drink bitterness. To clean the coffee machine Philips inside, you need to remove this unit.
First, open the service door located on the side or front of the chassis. Depending on the model, you may need to press the red release button or simply pull the handle towards you. Remove the unit carefully, holding it by the handle so as not to spill any remaining dry coffee. Place the removed mechanism on a flat surface covered with a towel.
Rinse the block under running warm water. Avoid using dishwashing detergents as they are difficult to rinse off completely and can ruin the taste of the coffee. Use only water and a brush to remove deposits from strainers and pistons. Allow the parts to dry naturally before reinstalling.
⚠️ Attention: It is strictly forbidden to wash the brewing unit in the dishwasher. High temperatures and aggressive detergents deform plastic gears and mechanism lubrication.
Pay special attention to mesh filters. If the holes are clogged, gently clean them with an old toothbrush. If you notice that the rubber seals on the pistons have lost their elasticity or are cracked, they need to be replaced. Dry coffee from the tray and pulp container should also be thrown away and the containers should be rinsed.
☑️ Checklist for mechanical cleaning
Decalcification procedure: step-by-step instructions
Decalcification is the process of removing mineral deposits (scale) from the internal pipes and boiler. Cars Philips are equipped with an intelligent system that itself signals the need for a procedure with a flashing indicator or a message on the display. However, if the water in your area is very hard, you can start the program earlier.
First, empty the water container and fill it with clean water up to the mark, then add descaler according to the proportions on the package. Usually this is one bottle per full tank. Reinsert the reservoir. In the coffee machine menu, select the mode Settings → Care → Decalcification or press the combination of buttons indicated in the instructions for your model (often these are the steam and coffee buttons at the same time).
The machine will begin the process, which takes about 20 to 30 minutes. It will alternately pump the solution into the system, pause to dissolve the scale, and drain the dirty water into the drip tray. It is important not to interrupt the process and monitor the liquid level in the pan so that it does not overflow. If this happens, the machine will stop and the procedure will have to start again.
What should I do if the scale indicator is constantly on?
If after several decalcification cycles the indicator does not go out, the water hardness sensor may be faulty. Try resetting the cup counter via the service menu or replace the AquaClean water filter if installed.
After completing the solution cycle, the machine will ask you to flush the system. To do this, you need to rinse the water tank, fill it with clean water and start the draining process again. This is necessary to flush out any remaining acid from the boiler. Repeat rinsing with clean water 2-3 times until a clear liquid comes out without bubbles or odor.
Cleaning the brewing system and pipes
In addition to the boiler, the tubes supplying water to the brewing unit and the cappuccino maker also become dirty. To clean them, there are special tablets that dissolve in water. They effectively break down fatty compounds that regular scale cannot remove. Regular use of such tablets helps maintain the pressure in the system at an optimal level.
If your model has an automatic cappuccino maker (for example, LatteGo), it must be disassembled and washed after each use. Milk fat dries very quickly and becomes an ideal environment for bacteria. Rinse all parts under hot water, using a brush for hard-to-reach areas.
For a classic cappuccino maker (pannarello), remove the outer metal tube and rubber nozzle. Curdled milk often accumulates inside the plastic case. Clean the interior with a brush and soak the parts in a warm solution of dishwashing detergent (external parts only, not the boiler!).
| Type of pollution | Cleaning agent | Treatment frequency | Risk of being ignored |
|---|---|---|---|
| Scale (lime) | Liquid decalcifier | Once every 2-3 months | Boiler breakdown, noise |
| Coffee oils | Cleaning tablets | Once a month | Bitter taste of coffee |
| Milk fat | Warm water, brush | Daily | Mold, bad smell |
| Dry coffee (dust) | Dry brush, vacuum cleaner | Once a week | Mechanisms sticking |
Use AquaClean filters (if supported by your model). They allow you to make up to 5000 cups without decalcification and significantly improve the taste of the drink by softening the water.
Removing coffee oils with tablets
The fatty compounds in coffee oxidize and become rancid. To clean the coffee machine Philips from these deposits, special cleaning tablets are used. They are gentler than descalers, but do an excellent job with organic matter.
The process is similar to decalcification, but instead of liquid, tablets are often placed in the tank (instructions may vary depending on the model: sometimes the tablet is placed in the ground coffee compartment). Run the cleaning program. The solution will circulate through the system, dissolving plaque. After the procedure, be sure to rinse the system with clean water as described above.
Some users prefer to use traditional methods, for example, a solution of citric acid. This is acceptable, but the concentration should be low (no more than 20-30 grams per liter) so as not to damage the seals. However, manufacturers strongly advise using certified chemicals that guarantee safety for food plastics.
⚠️ Attention: If after cleaning the coffee tastes strange or there is a chemical taste, it means you haven’t flushed the system properly. Repeat the rinsing cycle with clean water 2-3 times without interruption.
Maintenance of the cappuccino maker and steam wand
The steam wand is where bacteria are most likely to grow due to milk residue. After each froth, wipe the tube with a damp cloth and blow steam for 2-3 seconds. This will prevent the milk from sticking to the hole.
Do a deep clean once a month. Remove all removable pannarello parts. Soak them in warm water with dish soap for 15-20 minutes. Rinse thoroughly and dry. The inner tube (if it is removable) can be cleaned with a long brush.
For systems LatteGo It's simple: no tubes, just two containers. They can even be washed in the dishwasher (top rack), but manually with a brush is faster and more reliable. Make sure that there is no dried milk left in the connecting holes on the machine itself - carefully remove it with a damp cloth.
The hygiene of the cappuccino machine is more important than the decalcification of the boiler, since the dairy environment promotes the proliferation of pathogenic microorganisms that are hazardous to health.
Common mistakes when caring for a coffee machine
Many owners make mistakes that ruin all their care efforts. The most common is the use of distilled water. Distillate does not contain salts, and water hardness sensors may not read readings correctly, which will lead to electronic malfunctions. It is better to use filtered water.
Another mistake is rarely changing the water in the tank. Water that has stood for more than 2-3 days begins to “bloom” and acquire a musty smell. Change the water daily, even if you don't plan to brew coffee. This will extend the life of the pump and improve the taste of the drink.
Also, do not ignore the lubrication of the moving parts of the brewing unit. Although modern lubricants are used, once every 1-2 years (or when squeaking occurs) it is advisable to lubricate the guides with special food-grade silicone. This will ensure silent operation of the mechanism.
Recommendations for extending service life
To your Philips served for years, follow the operating mode. Do not brew more than 5 cups of coffee in a row without a break; let the heating element cool down. Constant operation at the limit of capabilities reduces the resource of the heating element.
Check the condition of the millstones regularly. If the coffee grinds become coarser at the same setting, or a metallic grinding sound appears, the millstones may have become dull or a foreign object has gotten into it. In such cases, it is necessary to disassemble and clean the millstone group from foreign matter.
Store the coffee machine in a dry place. High humidity can lead to oxidation of contacts and the appearance of mold inside the case. Following these simple rules will make your morning cup of coffee truly delicious.
How to store a coffee machine while away?
If you are leaving for a long time, completely empty the water tank, throw away the pulp, rinse the brewing unit and leave the door open to dry. This will prevent mold from forming.
Is it possible to use citric acid instead of a special product?
You can use it, but with caution. The concentration should not exceed 20-30 grams per liter. Citric acid is effective against scale, but does not contain corrosion inhibitors and softeners, which are found in professional chemicals, so frequent use can shorten the life of rubber seals.
Why does my coffee machine hum after cleaning?
The humming can be caused by residual air in the system (you need to make several idle spills of water) or by the fact that scale, having fallen off the walls, is stuck in a narrow place in the tube. In the latter case, repeated decalcification or the help of a specialist may be required.
How often should the brewing unit be lubricated?
Modern brewing units Philips/Saeco They have factory lubricant designed to last for several years. They need to be lubricated only if the mechanism begins to creak or jam, or after 3-4 years of active use. Use only food grade silicone grease.
What should I do if the machine says "Clean brewing unit"?
This is a standard reminder. Remove the unit, wash it with warm water without detergents, let it dry and insert it back until it clicks. The message will disappear after the brewing cycle.
Can the water tank be washed in the dishwasher?
Most plastic tanks can be washed in the dishwasher at temperatures no higher than 40-50 degrees. However, the cover with a magnetic sensor or electronics (if any) cannot be washed in a machine - only by hand.
