How to replace the grease for the coffee machine?

If the coffee maker, which is a loyal assistant to lovers of aromatic coffee, stops working, they will be greatly disappointed. Any repairs to the machine are an unwelcome procedure, and to avoid it, proper operation and regular preventive maintenance are necessary to ensure that the device remains in good condition.

If a driver fails to change the oil in their engine or gearbox, what will be the outcome for their beloved car? Indeed, an unfortunate fate awaits them, regardless of the quality of the oil used, as it has a limited lifespan. This analogy holds true for coffee machines produced by renowned global brands like Delonghi, Bosch, or Saeco. To prevent a similar undesirable scenario, it is advisable to periodically refresh or replace the current lubricant in these machines.

How to replace silicone grease

There may be situations when an urgent repair of a necessary item is needed, but the required material is not readily available. What should be done in such cases? If we are specifically discussing coffee machines, there is no need to despair, as all lubricants have a similar composition to food fats. In this scenario, Vaseline proves to be a quick and safe solution for your health.

All you need to do is acquire a tube of petroleum jelly and a syringe. Then, extract the contents of the tube using the syringe and apply an even layer onto the respective areas that require treatment. Such a straightforward and innovative method provides a solution to your predicament.

Lubrication of moving parts of the coffee machine, its importance

Note: The coffee machine contains mechanical components that may wear out over time. If these parts are not lubricated regularly, they may eventually break down due to the pressure and temperature they are exposed to during operation. To ensure that your coffee machine remains tight and operates smoothly, it is important to periodically apply a thin layer of lubricant to the surfaces where the moving parts come into contact. By following these simple lubrication procedures, you can greatly prolong the lifespan of your machine.

What to lubricate

First and foremost, the brewing unit of your coffee machine is rich in parts that undergo intensive rubbing. It is simple to remove this part from the casing, allowing for quick and easy application of a coating to its rubbing parts. If you own an automatic machine, it is essential to perform maintenance on the entire brewing unit.

Caution! Before beginning any work, it is important to adhere to basic safety precautions: ensure that the appliance is disconnected from the power source. Additionally, prior to lubricating the parts, it is necessary to clean all surfaces, removing any dust, coffee remnants, or old grease. An old cloth can be used for this purpose.

Important! When lubricating the parts of the brewing unit or cooking group, it is vital to apply the new material in a thin and even layer; using too much is not advisable, as excess lubricant may seep from various cracks. Rubber sealing rings and the corresponding grooves should also be treated. The same procedure should be done for gears, rotating axles, and, of course, the drive shaft. Afterward, the welding chamber guides should be treated as well. Once the lubrication process is complete, reassemble everything in the reverse order, taking care to properly place the o-rings. Congratulations, you have successfully maintained your beloved machine with minimal effort!

Lubricants for coffee machines

If we have already figured out the process of applying the material, then the question of what to use to lubricate the components of the food machine is a separate matter. It’s important to note that not all materials are suitable for this procedure.

Attention! It is not recommended to use materials that are designed for industrial units and machine assemblies, as this can be dangerous. Even a slight contamination of such material in your coffee can cause serious poisoning. Since coffee has a strong aroma and flavor, it may be difficult to detect the presence of these harmful substances.

Modern lubricants are classified into three categories or tolerances in the NSF system: H1, H2, H3. These classifications signify:

1. Materials intended for lubricating surfaces that come into indirect contact with food.
2. Intended for use in machines that do not come into direct contact with food.
3. Can be utilized in machines that have direct contact with food.

The NSF approval parameter serves as an indicator of the absence of any harmful or life-threatening substances in the material.

Assistance required! Certain renowned coffee machine manufacturers frequently include lubricant tubes with their products, providing information about the ingredients and instructions for use.

Brands of food-grade greases for coffee machines

OKS 1110 grease is a versatile silicone grease that is approved for use in the NSF system. It is commonly used for treating components of coffee machines. This grease is able to withstand cold and hot water, as well as liquids containing alcohol and even acetone. It has a complex chemical composition that includes silicone. Different sizes of packaging are available on the market, ranging from tubes to barrels weighing 180 kilograms.

Another popular coffee machine lubricant is EFELE, which also has H1 approval in the NSF system. One of the unique features of this lubricant is its ability to maintain its properties at high temperatures, reaching up to +160 degrees Celsius. It has excellent sealing properties and is resistant to most detergents. For convenience, it is available in 10-gram tubes for single use.
