Scream and tight course of the brewing block in coffee machines series Philips Saeco or Siemens Often indicate dried factory lubrication, which requires immediate replacement with a food analog. If you ignore this symptom, the mechanism begins to work with increased load, leading to wear of plastic gears of the drive and the appearance of cracks on the body of the unit. Owners of automatic espresso machines should understand that standard technical oils are categorically unacceptable because of direct contact with the product. The right selection lubricant It guarantees silent operation and extends the life of expensive equipment.
The choice of lubricant determines not only the comfort of operation, but also the safety of the prepared drink. In automatic coffee machines Philips special food lubricants based on silicone or synthetic oils approved by international safety standards are used. The use of inappropriate formulations, such as petroleum petroleum or vegetable oil, leads to their rapid oxidation, the formation of resins and the appearance of an unpleasant taste in coffee. It is important to use only certified products specifically designed for the food industry.
Regularity of service directly depends on the intensity of the use of the device. For home models preparing 3-5 cups a day, prevention is recommended every 6-8 months or after every second pack of grains. Professional devices in offices require more frequent intervention – every 2-3 months. Timely lubrication prevents jamming of the mechanism and reduces the noise level during the operation of the motor.
Criteria for the selection of lubricant for food mechanisms
When searching for a suitable composition, the condition is the presence of a label of food tolerance. The most common standard is NSF H1This is a test that confirms that the substance is safe in case of accidental contact with food in an amount of up to 10 ppm. Lubricants in this category have no smell, taste and color, which is critical for preserving the organoleptic properties of coffee. The use of technical analogues can lead to poisoning and breakdown of the machine.
The temperature of the work also plays a key role. The brewing block in the cars Philips Heated to 90-95 degrees Celsius, so the lubricant should not melt, drain or change its viscosity at such temperatures. Silicone oils do this job perfectly, maintaining stability over a wide range of temperatures. In addition, they have water repellent properties, protecting metal parts from corrosion.
⚠️ Warning: Never use WD-40, engine oil, solidol or ordinary sunflower oil to lubricate your coffee machine. These substances are toxic when ingested and can destroy the plastic parts of the mechanism.
The consistency of the substance should be optimal for plastic friction pairs. Too liquid oils will be quickly washed out with water when washing the system, and too thick can make it difficult to run the mechanism in a cold state. The ideal option is translucent gels or pastes of medium viscosity. They are well held on the surface of the parts and do not flow under the action of centrifugal force during rotation.
When buying lubricant, pay attention to the volume of packaging. For home use, it is optimal to buy tubes or syringes with a volume of 10-20 ml, since the shelf life of open packaging is limited.
Overview of popular brands of lubricants for coffee machines
There are several proven brands on the market, which are recommended by coffee manufacturers.

Instructions for lubrication of the Philips brewing block
The maintenance process begins with the removal of the brew group from the body of the machine. To do this, open the service door and press the red fixation button, then smoothly pull the node on yourself. It is important not to make excessive efforts to avoid breaking plastic latches. After extraction, the block must be thoroughly washed with warm water without the use of detergents, removing all the remnants of coffee gruel.
After drying, start applying the lubricant. Pay special attention to the side rails that walk on the rails inside the machine, as well as the occupant rings of pistons. The lubricant is applied in a thin layer with a finger or a special brush. You do not need to stuff lubricant into the cracks - it should cover the rubbing surfaces with a uniform film. Excess material can squeeze out during work and get into the drink.
☑️ Checklist of lubrication of the brewing block
Special attention is required to sealing rings. If they look dry or cracked, the lubricant will not help - you will need to replace the rubber bands. When lubricating, make sure that the substance gets into all the grooves of the seals. This will restore their elasticity and tightness. After processing, collect the block (if it has been disassembled) and set it back into the machine before the characteristic click.
⚠️ Warning: Do not lubricate the electrical contacts, sensors, and inside of the grinder. Lubrication is intended only for mechanical moving parts of the brewing unit.
Do I need to remove the entire block?
Complete disassembly is rarely required, only during major repairs. For prevention, it is enough to remove the upper cover and lubricate the visible guides and seals, without touching the complex internal mechanics.
Frequent errors in the maintenance of coffee machines
One of the most common mistakes is to use excessive amounts of lubrication. Owners often sin by smearing the mechanism “just in case”. As a result, during the first brewing cycles, the excess is squeezed out and mixed with coffee, forming black slurry, which clogs the drainage system. This can lead to the “Empty the waste pan” error even when the pallet is empty.
Another mistake is to lubricate dirty parts. Applying a new lubricant over an old coffee gruel creates an abrasive paste that works like sandpaper for plastic. Careful care is required before each service procedure smelting. Also, you should not mix different types of lubricants, as their chemical composition may be incompatible, which will lead to loss of properties.
- ❌ Using WD-40 to eliminate squeaking leads to the destruction of plastic.
- ❌ The dry seals are greased without prior washing - accelerates wear.
- ❌ Ignoring the disassembly instructions is the risk of breaking the fixtures.
- ❌ The use of solidol or litol is toxic and thickens in the cold.
Some users try to lubricate the grinder, which is strictly forbidden. Coffee should be prayed "for dry", any fat content of the beans or the oil entering the millstone will lead to the fact that the coffee will cease to pour into the brewing chamber. If the grinder is making noise, it is usually a sign of wear of the millstones or hitting a foreign object, rather than a lack of lubrication.
Diagnostics of lubrication problems and their solution
It is time to update the lubricant, you can understand by a number of indirect signs. First of all, it is a change in the sound of the machine. If the previously quiet brewing process was accompanied by a grinding, hum or intermittent buzzing, then the friction of the details increased. Also this is indicated by the tight course of the brewing block when extracted - it should be removed with moderate effort, and not with jerks.
Visual inspection will also tell a lot about the state of the mechanism. If you removed the block and saw that the side runners are dry, matte or have traces of production (scratches, scuffs), then there is no lubricating layer. In normal condition, the surfaces should be slightly greasy to the touch. The appearance of cracks on plastic elements can also be a consequence of working "dry".
⚠️ Warning: If the machine makes strange sounds or makes an error after lubrication, stop using immediately and check the correct assembly of the brewing unit.
Timely lubrication prolongs the life of the coffee machine by 2-3 times and preserves the quality of coffee, preventing the ingress of foreign tastes.
In some cases, even after lubrication, problems persist. This may indicate mechanical wear of parts that cannot be repaired by maintenance. For example, if the teeth on the gears of the drive are slicked or the brewing block itself is deformed, replacement of the nodes will be required. Regular maintenance helps to identify such problems at an early stage.
Questions and answers about the care of the coffee machine
Can I use Vaseline instead of a special lubricant?
No, conventional pharmacy jelly is not intended for high temperatures and food use in such conditions. It can melt, drain and give coffee an unpleasant taste, as well as quickly wash out with water.
How often should you lubricate a Philips coffee machine?
The optimal frequency is once every 3-4 months with active use or every 2-3 months for office cars. Also, lubrication is carried out when a creak or a tight course of the brewing block appears.
What is the danger of lack of lubrication in the brewing block?
Working without lubrication leads to overheating of rubbing parts, wear of plastic gears, cracks in the block body and, ultimately, to expensive repairs or replacement of the unit.
Where to buy the original Philips lubricant?
Original lubricants are sold in authorized service centers, large home appliance stores and on the official websites of manufacturers. Also suitable analogues with the labeling Food Grade from the stores of radio parts or chemistry.
Do I need to lubricate the coffee grinder inside the car?
Absolutely not. The grinders must remain dry. The entry of oil or lubricant into the grinder will lead to the adhesion of the coffee and breakage of the grinding mechanism.
