Timely maintenance of a coffee maker is not just a whim, but a necessity for each owner. DeLonghi. Many users ignore the mechanical part, focusing only on scaling, which is a gross mistake. Inside the device constantly moving metal parts, which eventually lose the factory lubrication.
If you notice that cook-block When you start to move with difficulty or have an unpleasant creak, it’s time to act. The absence of a lubricating layer leads to friction of the plastic against the metal, which causes wear of the seals and even breakage of the gears. In this article, we will discuss how to lubricate a coffee machine. DeLonghi And how to do it right.
The procedure does not require deep technical knowledge, but requires accuracy and compliance with safety rules. The wrong substance can spoil rubber parts or change the taste of your espresso. Therefore, it is important to use only silicone-greaseApproved for contact with food.
Signs of the need for lubrication and diagnosis
To understand that the mechanism needs help, you can by the characteristic sounds and behavior of the device. Often owners notice a problem when the creak becomes loud and distinct. However, it is better not to bring the equipment to such a state, since wear at this point is already proceeding at an active pace.
Pay attention to the effort required when removing the brewing block. If it is removed with noticeable resistance or "sticks", then the pistons of the pump and guides need processing. Also, the feature can be an uneven movement of the mechanism during the brewing cycle.
Visual inspection helps to identify the absence of a thick layer of lubrication on metal rods. If you see dry areas or, conversely, a mixture of old lubricant and coffee dust resembling abrasive paste, cleaning and lubrication are required.
⚠️ Attention: If the coffee machine makes a loud crackle or knock, do not try to lubricate it. This may indicate mechanical damage to the gears or hitting a foreign object that requires disassembly and repair.
Regular checks on the condition of the moving parts should be part of your maintenance ritual along with decalcination. This will prevent costly repairs and prolong your life. DeLonghi Magnifica or Esam for years to come.
Choosing the Right Lubricant
The question of how to lubricate the coffee machine DeLonghi, is critical. The market offers many options, but not all of them are suitable for food technology. The use of inappropriate substances can lead to the destruction of rubber seals.
The main requirement is food safety. The lubricant should not release toxic substances when heated and contact with water, which then enters the cup. The best choice is silicone-based formulations labeled "Food Grade".
- 🛢️ Silicone lubricant: The ideal option, which retains the elasticity of rubber and is not washed away with water.
- 🥄 Vaseline oil: A valid but less durable alternative that requires more frequent application.
- 🚫 Vegetable oil: It is strictly forbidden, since it dries, forms a sticky film and rancid.
- 🚫 Lithium lubricants: They are not suitable for food equipment and can damage plastic.
Specialized lubricants, such as DeLonghi EcoDecalk (Although this is a remedy for scale, the brand has lubricants) or analogues from Mellerud and TopEcologicalIt is designed with the specifics of coffee equipment in mind. They can withstand high temperatures and pressure.
Don’t save on this expendable material. A tube of high-quality lubrication is enough for several years of regular use, and the risk of spoiling expensive equipment with a cheap analogue is too great. Always check the packaging for a safety label for food contact.
Preparation for the maintenance procedure
Before you start greasing the coffee machine DeLonghiCareful preparation is required. This includes not only the purchase of materials, but also the provision of safe working conditions. First of all, the device must be de-energized.
Remove the power cord from the socket and let the machine cool completely if it has been working recently. Hot elements can cause a burn, and the residual pressure in the system - the release of boiling water. Wait until the indicators go out.
You will need the following tools and materials:
- 🧤 Silicone lubricant: Basic consumables.
- 🧽 The rags without the pile: Removing old dirt and excess.
- 💧 Warm water: To wash the removable parts.
- 🥄 Soft brush: To clean up hard-to-reach places.
Prepare the work surface. Cover the table with a towel or plastic to avoid staining the furniture. The lubricant can drip, and it is better to foresee this in advance. Also make sure you have enough space to accommodate the removed brewing block.
If you plan to lubricate internal mechanisms that are not visible with normal access, you may need to remove the side panel of the case. To do this, you will need a cross screwdriver and possibly a flat blade for careful removal of latches.
⚠️ Attention: Never perform maintenance work while the device is connected to the power grid. This safety rule cannot be violated.
Lubrication of the brewing block (Bryggroup)
The Brewing Block is the Heart of the Coffee Machine DeLonghi. This is where the coffee pill and the water spill occur. This unit requires the most frequent attention and regular lubrication of mobile connections.
First, remove the brewing block according to the instructions for your model. Usually you need to open the service door, press the red locks and pull the block on yourself. Wash it under warm water without using detergents to remove coffee dust.
Pay special attention to the side guides and pistons. On the side walls of the block there are protrusions that walk along the guides inside the car body. They must be covered with a thin layer of silicone lubricant. Also lubricated rubber seals on the ends of the block so that they do not dry out.
The application process is as follows:
- 🧼 Cleaning: Carefully remove all remnants of old lubricant and coffee plaque.
- 💧 Drying: Let the parts dry naturally or wipe with dry rags.
- 🛢️ Application: Apply a small amount of lubrication to the moving parts.
- 🔄 Distribution: Press the pistons several times with your hands so that the lubricant is evenly distributed.
Don't put too much lubrication on. The excess can mix with coffee and worsen the taste of the drink, as well as attract more dust. A thin, barely noticeable film is enough for effective work.
☑️ Checking the brewing block
After processing, set the block back to the characteristic click. Make several blank water spills without coffee to remove any excess lubricant from the system.
Maintenance of pumps and internal mechanisms
If your model DeLonghi (e.g. series) Magnifica S or PrimaDonna) requires more in-depth maintenance, you will have to look inside the shell. There is a pump (pump) and a system of tubes, which may also need lubrication.
To access the insides, remove the top cover and side panel. Be careful with plastic latches – they are fragile. Find the vibropomp, which is usually located at the bottom of the device. The pump rod transmitting the movement must be lubricated.
It is also worth checking the connection of silicone tubes with fittings. Rubber tans over time, and light lubrication of the joints will help to maintain the tightness and elasticity of the joints. Use the same food silicone lubricant.
Inside the case, you can detect the mechanism of the drive of the brewing block. The gears and shafts here may also require attention if they look dry. However, if the factory lubricant on the gears looks clean and thick, you do not need to touch it.
| Node. | Type of lubricant | Frequency of processing | Signs of necessity |
|---|---|---|---|
| Brewing block | Food silicone | Every 3-6 months | Scream, tight move. |
| Pistons pump | Food silicone | Once a year. | Pump noise |
| Guide corps | Food silicone | Every time you clean the block | Metal dryness |
| Wheel drive. | Plastic lubrication | As it dries out | Knock, gnash. |
When assembling the case, make sure that all wires are stacked in their channels and do not fall under moving parts. Incorrect assembly can lead to short circuit or jamming of mechanisms.
⚠️ Attention: When disassembling the case, you may lose the warranty on the device. If the coffee machine is still on warranty service, it is better to contact an authorized service center.
Frequent mistakes in lubricating the coffee machine
Many users, trying to help their technique, make mistakes that lead to the opposite effect. The most common of these is the use of inappropriate oils. Vegetable or machine oil quickly turns into adhesive mass.
Another mistake is excessive diligence. Some people pour lubrication literally liters, believing that “the porridge with oil can not spoil”. In the case of the coffee machine DeLonghi This causes the lubricant to enter the brewing chamber and mix with the coffee.
Ignoring cleaning before lubrication is a fatal mistake. If you apply a new layer of lubricant over an old one contaminated with coffee dust, you will create the perfect abrasive. This mixture will wash plastic parts faster than working on dry.
What happens if you use WD-40?
WD-40 is not a lubricant, but a solvent with light oily additives. It will wash away the remnants of the factory lubricant, destroy some plastics and rubber, and make coffee unfit for drinking due to its chemical smell and taste.
It is also important to remember to wash the system after lubrication. The first cycle of brewing is better to spend without coffee, just by driving the water. This will wash away the excess matter from the outer surfaces of the brewing block.
Remember that regularity is more important than quantity. It is better to lubricate the mechanism a little more often, but with less substance than to arrange rare "oil baths" for your equipment.
Outcome recommendations and prevention
Coffee machine care DeLonghi It is a set of measures where lubrication plays a key role along with decalcification. Compliance with simple rules will allow your technique to work silently and efficiently for many years.
Always use only specialized tools. Do not experiment with improvised materials, as repair or replacement of knots can cost much more than a tube of good lubrication. Careful attitude to rubber seals will keep the pressure in the system.
Conduct a visual inspection of the brewing unit every time you wash it under the tap. It will take a couple of seconds, but it will help to notice the lubricant drying at an early stage.
If you are unsure of your abilities or are afraid of damaging complex mechanisms, entrust deep service to professionals. However, the basic lubrication of the brewing unit can and should be performed by each owner.
The use of proper food silicone lubricant prolongs the service life of the mobile parts of the coffee machine by 2-3 times and maintains the silence of the device.
Keep your clean, use quality consumables, and yours DeLonghi It will delight you with aromatic coffee every morning without unnecessary sounds and malfunctions.
Frequently Asked Questions (FAQ)
