Regular drinking of coffee turns into a ritual, which pleases only when the drink has a rich taste and pleasant aroma. However, over time, owners of automatic devices notice that the espresso becomes bitter, and the foam becomes pale and quickly settles. The reason for this phenomenon is often not the quality of the grains, but the accumulation coffee oils inside the brewing mechanism and hydraulic system.
Ignoring the need for cleaning leads to clogging of thin channels and failure of expensive equipment. Internal surfaces Philips Saeco or Series 2000/3000/5000 become covered with a sticky coating that is almost impossible to wash off with plain water. Coffee oils oxidize when exposed to air, acquiring a rancid taste that is transmitted to each new serving of the drink.
In this article we will analyze in detail the process of removing fat deposits, using specialized tools and the correct sequence of actions. You will learn how often you need to carry out the procedure, which solutions are safe for plastic parts, and how to return your machine to factory performance without contacting a service center.
Why coffee oils are dangerous for Philips automation
During the process of making espresso, not only flavor substances, but also lipids are extracted from ground beans under high pressure. These fats are essential to create a thick cream, but too much of them becomes a problem. Passing through the brewing unit, hot water leaves a microscopic film on the walls, which over time hardens and turns into a resinous mass.
The accumulation of this plaque disrupts the work brewing device, which is the heart of the coffee machine. The mechanism begins to jam, the motor experiences increased load, and the O-rings lose their elasticity. In models Philips LatteGo or Xelsis milk supply tubes may become clogged, which will lead to extraneous sounds and decreased pressure.
In addition to mechanical damage, oxidized fats create an ideal environment for the proliferation of bacteria. This not only affects the user's health, but also gives the drink an unpleasant taste of old coffee. Even the use of elite varieties of grains will not save the situation if the internal pathways are polluted.
Symptoms of contamination and the need for decalcification
You can determine the moment when cleaning from coffee oils becomes critical using a number of indirect signs. The machine rarely reports this directly, as sensors usually only monitor the presence of scale. However, an attentive user will notice changes in the operation of the device long before it breaks down.
Pay attention to the following signals that indicate the need for immediate intervention:
- 📉 The coffee stream has become sluggish, intermittent, or changed color to darker, almost black.
- 👃 There is a smell of burnt or rancid oil when turning on the machine or during cooking.
- 🔊 The brewing unit makes squeaking or wheezing sounds when the piston moves.
- 🧼 The foam on the surface of the espresso has become large, uneven and disappears quickly.
Users often confuse the need to remove fats with the descaling procedure. Decalcification (Descale) fights mineral deposits of calcium and magnesium using acid solutions. To combat organic contaminants, alkaline or enzymatic agents capable of breaking down fats are required. Using acid instead of fat will not work, and in some cases may even “seal” the plaque.
⚠️ Attention: Do not try to use vinegar or citric acid to remove coffee oils. An acidic environment does not dissolve fats effectively and can damage the rubber seals of the brewing unit, causing leaks.
Choosing a Safe Cleaning Product
The market offers many chemistry options for coffee equipment, but owners Philips you have to be selective. The manufacturer recommends using original tablets Philips Saeco or specialized liquids that do not contain chlorine and aggressive solvents. The plastic from which internal tanks and pipelines are made is sensitive to aggressive chemicals.
When choosing a product, be guided by its composition and purpose. Oil removing tablets are often labeled "Cleaning Tablet" or "Degreasing". They work more slowly than descaling agents, requiring time for the chemical reaction to occur. Liquid concentrates are more convenient to dose, but their price is usually higher.
A comparison of popular types of cleaning products is presented in the table below:
| Product type | Base | Effective against oils | Safety for plastic |
|---|---|---|---|
| Original Philips tablets | Alkaline + enzymes | High | Full |
| Liquid cleaners (Durgol and analogues) | Surfactants and alkalis | Medium/High | High |
| Descaling agents (acidic) | Citric/Lactic Acid | Low (0%) | Average |
| Household chemicals (Fairy, etc.) | Surfactants | Average | Risk of foaming |
Remaining foam can damage the pump or water level sensors. Specialized tablets designed to dissolve completely and wash away without leaving any residue.
Can tablets be used in dishwashers?
No, you can't. They contain fragrances, salts and components that can be toxic if ingested and are not intended for contact with drinking water in such quantities. They can also cause excessive foaming, which can be harmful to your pump.
Preparing the coffee machine for cleaning
Before starting the active phase of oil removal, the device must be properly prepared. This will ensure the safety of the process and maximum effectiveness of the cleaning product. Neglecting the preparatory stage may result in the solution not getting into the required nodes or being diluted with residual water.
Complete the following steps before starting a cleaning cycle:
- 🔌 Turn off the coffee machine with the power button and disconnect the network cable.
- 💧 Empty the drip tray and used coffee grounds container.
- 🚿 Rinse the brewing unit under running water without using detergents.
- 🌡️ Let the machine cool down if it has just been running to avoid burns when disassembling.
Pay special attention to the brewing unit. In models Philips Series it is removed through the service door on the left. Gently pull the handle towards you and remove the unit. Visually inspect it: if a thick brown coating is visible on the mesh, rinse it with warm water. Do not use brushes with hard bristles to avoid damaging the Teflon coating.
Also check the bean container. If there are old grains left in it, they must be removed, since during the cleaning process the machine will pump the solution through the millstones. If any cleaning agent gets into the bean hopper, it will ruin your entire supply of coffee.
☑️ Preparing for cleaning
Step-by-step instructions: cleaning the brewing unit and hydraulic system
There are two main cleaning methods: automatic (wash cycle with tablet) and manual (soak). The automatic method is suitable for regular maintenance when contamination has not yet become critical. The manual method is necessary if the machine has not been serviced for a long time or shows signs of severe contamination.
Automatic tablet cleaning:
To start the cycle, place one cleaning tablet in the ground coffee compartment (through the hatch) or directly into the brewing unit, if the instructions for your model Philips admits this. Insert the brewing unit back until it clicks. Fill the water tank with clean, cold water to the maximum.
Turn on the car. Depending on the model, press and hold the steam button or select a menu item Menu → Maintenance → Clean. The machine will begin the process, which takes about 10-15 minutes. During this time, she will pump the solution through the system and then flush it with clean water several times.
Manual cleaning (for deep cleansing):
If the automatic cycle is not enough, you can soak the brewing unit. Prepare a solution of warm water and cleaning agent in the proportion specified by the chemical manufacturer. Place the removed brewing unit in the container with the solution for 30-40 minutes.
After soaking, rinse the block thoroughly with running water. Reassemble the machine and run the hot water cycle (without coffee) 3-4 times to completely flush out any remaining chemicals from the pipes. This is a critical step as any remaining lye can be hazardous to your health.
After manually washing the brewing unit, lubricate the piston guides with food-grade silicone oil. This will extend the service life of the seals and make the mechanism operate silently.
⚠️ Attention: Never leave the brewing unit in the cleaning solution overnight or longer than recommended. Aggressive components can destroy plastic piston drive gears.
Care of the cappuccino maker and prevention of contamination
Owners of models with an automatic cappuccino maker (LatteGo, built-in faucet) are faced with the problem of milk drying out in the tubes. Milk fat combines with coffee oils to form plugs that are difficult to remove. Regular flushing of the milk system is an essential part of maintenance.
Immediately after preparing a milk drink, start the quick rinse function. In cars Philips this is often done by turning the steam adjustment wheel or through the menu. If you are using a removable cappuccino maker LatteGo, disassemble it into its component parts and wash it in the dishwasher or under a faucet with a brush.
To prevent oil plugs from forming in steam pipes, use the following technique:
- 🥛 After each use of milk, rinse the system with clean water.
- 🔥 Regularly wipe the steam wand with a damp cloth immediately after releasing steam.
- 🧼 Once a month, clean the cappuccino maker with a special product for dairy systems.
Don't forget that water quality also plays a role. The use of filtered water reduces the amount of scale, which indirectly helps to keep the system clean, since less fat settles on the walls that are smooth from calcium deposits.
An integrated approach: a combination of regular decalcification, cleaning of oils and flushing of the milk system guarantees the service life of your Philips coffee machine for up to 10 years or more.
Frequently asked questions (FAQ)
How often should coffee oils be cleaned?
The optimal frequency depends on the intensity of use. When preparing 3-5 cups per day, it is recommended to carry out the procedure once every 2-3 months or after every 300 prepared servings. If you are using dark roast coffee (which is more oily), the frequency should be increased.
Can descaling tablets be used instead of cleaning tablets?
No, these are different chemical compositions. Anti-scale tablets (decalcifiers) are acidic and remove minerals. Cleaning tablets (degrassers) are alkaline and break down fats. Improper use will not produce results and may damage the machine.
What should I do if my coffee still tastes bitter after cleaning?
If cleaning does not help, check the grind level. Grinding too fine can lead to over-extraction and bitterness. It is also possible that contamination has reached the internal boilers, which requires professional disassembly and ultrasonic cleaning at a service center.
Is it safe to use vinegar to clean Philips?
The use of vinegar is not recommended by the manufacturer. Acetic acid can damage rubber seals and plastic parts, and has a lingering odor that is difficult to clean up. It is better to use certified food safe products.
