An early morning ritual for millions of people is unthinkable without a cup of fragrant espresso cooked in a home coffee machine. But over time, even the most reliable technique Delonghi It starts to crumple: the stream of coffee becomes weak, the steam from the cappuccinator goes barely, and a strange sediment appears at the bottom of the cup. These are sure signs that the internal hydraulic system and the brewing unit have accumulated contaminants that require immediate intervention.
Ignoring the need for maintenance leads to serious consequences, up to the failure of expensive nodes. Scale., formed on the heating elements, significantly reduces thermal conductivity, causing the device to work for wear. In this article, we will discuss in detail how to properly clean a carob coffee maker so that it again pleases you with the perfect drink.
It is important to understand that the care process is divided into two main stages: the removal of lime deposits (decalcination) and mechanical cleaning of coffee oils and ground grain residues. Delonghi The technique is reliable, but it requires careful attention and the use of the right tools. Let’s start with the most important thing: preparation for the process.
Preparation for cleaning and necessary means
Before you start taking action, make sure you have all the tools and chemistry you need. The use of inappropriate substances can damage the seals or the appearance of a foreign taste in the coffee. For quality work, you will need a specialized scale removal tool, which can be purchased in household appliance stores or use citric acid, if the manufacturer explicitly allows this in the instructions for your model.
Also, don’t forget to prepare a container for collecting liquid. The volume of the water tank at the carob coffee makers Delonghi It is usually about 1-1.5 liters, so the bowl or jug should be of the appropriate size. Disconnect the device from the network in advance and let it cool completely if it just worked. This is the basic safety rule that categorically ignore.
⚠️ Warning: Never use pure acetic acid or aggressive household appliances to wash your plumbing. They can eat rubber pads and plastic tubes inside the machine.
For mechanical cleaning, a soft sponge, a toothbrush (new) for hard-to-reach places and dry lilaless fabric are useful. If your model has a removable pallet for drops, it is better to wash it immediately under the tap with a regular detergent. Preparing the workplace will take no more than 5-10 minutes, but it will save you nerves in the process.
Delonghi coffee maker decalcination process
Scale removal is a procedure that needs to be done regularly, especially if you live in a hard water region. In modern models Delonghi Often there is an indicator that signals the need for this operation. If there is no such indicator, focus on the frequency of use: on average, decalcination is carried out every 2-3 months.
First, prepare the solution according to the instructions on the package of the product. Usually, a certain amount of concentrate is required to be mixed with water in the tank. Pour the resulting mixture into a water tank and set it in place. Substitute a large container under the horn and the cappuccinator tube, as the liquid will come out of both holes.
Turn on the car and wait for the exit to work mode. Further, the algorithm of actions depends on the specific model, but the general principle is the same: you need to drive the hot solution through the system. On some models, you need to press and hold the steam button, on others - a special key combination. Watch the indicators on the control panel.
The decalcination cycle should be repeated 2-3 times until the reservoir is empty, taking breaks of 10-15 minutes for better dissolution of the deposits.
After the whole solution has passed through the system, be sure to rinse the tank with clean water and pour it again. Now you need to drive through the machine 2-3 full tanks of clean water to completely wash the remnants of chemistry. This is a critical stage, otherwise your next espresso will have a nasty chemical flavor.
Cleaning the brewing block and the horn
While the hydraulic system is free of scale, it is time to mechanically clean the nodes in contact with coffee. The horn (holder) and filter basket should be washed thoroughly. Use hot water and a brush to remove stuck coffee particles. Pay special attention to the filter grid: if the holes are clogged, the water pressure will drop, and the extraction will not be carried out correctly.
The brewing block is the heart of your coffee maker. In carob models Delonghi It is often hidden inside the body, but access to it is possible through the upper cover or hatch. If your model allows you to remove the brewing knot, do it carefully. Wash it under warm running water. Don't use it. detergents that form abundant foam, as they are difficult to completely rinse.
- 🧼 Carefully wipe the sealing gum on the brew block, removing the sticky coffee plaque.
- 🚿 Wash the strainer of the group (the place where the horn is inserted) with a special brush or brush.
- 🔍 Examine the interior walls for cracks or damage.
If the brewing unit is non-removable, use the reverse wash method (if the model supports) or simply run clean water through the system several times. It is also effective to use special cleaning tablets for coffee machines that dissolve coffee oils better than regular water.
☑️ Checklist for cleaning the brewing knot
Care for the capucinator (panarello)
The cappuccinator is the node that is contaminated the fastest, since milk tends to dry and turn into a hard crust that clogs the steam supply channels. If you notice that the steam is going weak or splashing, the problem is here. Remove the external nozzle (panarello) from the tube.
Soak the removed parts in warm water for 10-15 minutes. This will soften the dried milk. Use a thin spoke or a special needle coming complete with a coffee maker to clear the steam exit hole. Do this carefully so as not to expand the hole and not to disturb the geometry of the jet.
⚠️ Warning: Before removing the nozzle, panarello be sure to release the remnants of steam by pressing the feed button to avoid burns to the hands.
The internal tube that remained on the body of the car must also be cleaned. Blow it with steam, dipping the end into a glass of water. If the plaque is strong, you can use a brush to clean small diameter bottles. Regular cleaning of the capcinate after each use (purging with steam and rubbing with a wet cloth) will save you from having to carry out this complicated procedure too often.
The secret of the perfect foam
To get a thick and dense cappuccino foam, use only cold milk with a fat content of 3.2-3.5% and start whipping immediately after the steam mode is turned on, without waiting for the condensation to come out.
Comparison of cleaning products: what to choose?
On the shelves of stores you can find many tools for caring for coffee machines. Choosing between Original Chemistry DelonghiUniversal analogues and folk methods often cause controversy. Let’s discuss the main options so that you can make an informed decision.
Original means such as EcoDecalkIt is designed with the materials used in specific models. They are guaranteed not to damage plastic and rubber. Universal remedies based on sulfamic acid are also effective, but require strict dosage. Citric acid is a budget option, but it is less effective against older deposits.
| Type of instrument | Efficiency | Security for nodes | Price. |
|---|---|---|---|
| The Original (EcoDecalk) | Tall. | Maximum | Tall. |
| Universal (liquid) | Tall. | Medium | Medium |
| Citric acid | Medium | Low (Crystal Risk) | Low. |
| Cleaning pills | High (for oils) | Tall. | Medium |
When choosing, pay attention to the composition. If in the instructions to your Delonghi The use of liquids is indicated only, do not experiment with decalcination tablets, as they may not dissolve completely and damage the pump. To remove coffee oils, on the contrary, tablets are ideal.
Frequent errors in service
Even experienced users sometimes make mistakes that shorten the life of the appliance. One of the most common is the use of distilled water. That's a misconception. Distilled water is devoid of minerals, but it is also devoid of buffer capacity and can be more aggressive to some alloys and water level sensors. It is better to use filtered water or water in bottles with medium hardness.
Another mistake is ignoring the schedule for replacing softener filters if they are installed in the tank. The resource-experiencing filter stops working and may even start flushing accumulated contaminants back into the water. Change them strictly after the manufacturer's specified time, usually 2 months or 50 liters of water.
- 🚫 Forgetting about the drain of water for the winter (if the car is in an unheated room).
- 🚫 Using abrasive sponges to clean the outer surfaces, leaving scratches.
- 🚫 Attempt to disassemble the electrical part of the machine without the appropriate skills.
Remember that guarantee The device may be cancelled if the service center finds evidence of the use of aggressive or inappropriate cleaning products. Always read the instructions before using a new chemical.
To extend the life of a coffee maker, install a magnetic or polyphosphate water softener on the tap. This will reduce the rate of scale formation at times.
Can I use vinegar to clean Delonghi?
Using regular table cider vinegar is not recommended. It has a pungent odor that is very difficult to wash out of the system and can negatively affect rubber seals when used frequently. It is better to use special products or citric acid in the correct concentration.
How often should a complete cleaning be done?
Decalcination (scaling removal) is carried out every 2-3 months, depending on the hardness of the water. Mechanical cleaning of the brewing unit and horn - once a week with active use. General cleaning with oil tablets - once every 1-2 months.
What to do if the coffee is not good after cleaning?
If the taste persists after decalcination, it is possible that the coffee oils in the brewing block are contaminated. Use special cleaning pills. Also check the quality of the water and the freshness of the coffee beans.
Why does the coffee maker make noise after cleaning?
Noise can be caused by air entering the system. Try turning on and off the steam and water supply several times. If the noise persists and is accompanied by vibration, it may be necessary to lubricate or replace the pump.
Regular and proper care of the coffee maker Delonghi It is a guarantee of her long service and your excellent mood in the morning. Do not be afraid to carry out these procedures yourself, because they are not difficult, if you follow the instructions and common sense. Your technique will respond to you with a steady job and a cup of perfect coffee.
