Regular maintenance of the coffee maker is the key not only to long service of the equipment, but also to preserve the rich taste of your favorite drink. Owners of machines Krups Often faced with the need to remove mineral deposits, which inevitably accumulate in the heating system. Ignoring this procedure can lead to a decrease in pressure, an increase in the time of preparing espresso and, in the worst case, to the failure of expensive nodes.
The maintenance process is divided into two main stages: decalcination (removal of scale) and cleaning of coffee oils. Scale. These are solid deposits of calcium and magnesium salts, which are formed when water is heated. Oils oxidize over time, giving coffee bitterness and an unpleasant taste of rancid fat. Understanding the difference between these contaminants is critical to choosing the right cleaning method.
Modern models of the brand are often equipped with automatic programs that greatly simplify the life of the user. However, even the presence of smart algorithms does not relieve the owner of the need to know the basic principles of care of the device. In this guide, we will discuss all the nuances in detail to ensure that your Krups I have enjoyed the perfect coffee for many years.
Signs of the need to clean the coffee machine
To determine the moment when the equipment requires help, it is possible on a number of indirect signs that appear in the process of operation. The first signal is often a change in the sound of the work: the pump begins to buzz louder or, conversely, quieter, and the steam from the nose of the cappuccinator comes out in jerks. This suggests that the ducts are narrowed by sediments.
Visual diagnosis also plays an important role. If you notice that the espresso stream has become sluggish, intermittent or splashing, then the pressure in the system has dropped due to blockages. In addition, on the surface of the finished drink can disappear characteristic dense foam. creamCoffee itself has a sour or metallic taste.
⚠️ Attention: If the decalcination indicator lights up red or flashes, you can not postpone the procedure. Prolonged work with the indicator turned on can lead to overheating of the TEN and its subsequent burnout.
Many users also pay attention to the amount of water passing through. If the machine runs more water than usual to prepare one cup of espresso, or, conversely, stops prematurely, this is a sure sign of a hydraulic disorder. In such cases, immediate intervention will help avoid costly repairs.
Preparation for the decalcination procedure
Before starting any work with liquids, it is necessary to properly prepare the workplace and the apparatus itself. Make sure the coffee machine is turned off and cooled if it was running immediately before. Remove the drip tray and rinse it with warm water with a mild detergent to remove the remnants of old coffee and mold formations.
To prepare the solution, you will need clean water and a special means to remove scale. Although some users prefer folk methods such as citric acid or vinegar, the manufacturer Krups It is recommended to use specialized liquids. They have an optimal acidity that effectively dissolves carbonates without damaging the rubber seals and plastic tubes inside the device.
Use only filtered or bottled water to make your coffee. This will significantly reduce the rate of scale formation and prolong the intervals between services.
It is also important to check the condition of the filters in the water tank if the model provides for their presence. A clogged filter can interfere with normal fluid flow during flushing. Remove the tank, rinse it and make sure there are no visible contaminants on the walls.
- 🧼 Wash the water tank with warm water without using aggressive chemicals.
- 💧 Prepare a container of at least 1 liter to collect the washing fluid.
- 🧤 When working with concentrated decalcination means, it is recommended to use rubber gloves.
- 📖 Read the instructions for your specific model Krups for specific requirements for the volume of the solution.
Automatic cleaning program (for models with display)
Most of the modern automatic coffee machines Krups They are equipped with a built-in algorithm for removing scale. The program is usually initiated through the settings menu or when the corresponding indicator is lit. The process is completely controlled by electronics, which alternates the supply of solution and clean water, pausing to influence the chemistry on the deposits.
To start, you need to fill the tank with a mixture of water and decalcination means in the proportion specified in the instructions (usually 1 cap of the product per 1 liter of water). Then substitute a large container under the capuchinator and dispenser for coffee. In the menu, select a paragraph Menu → Service → Decalcination and confirm the action.
The machine will start pumping the solution through the system. At certain points, the process can stop - this is a normal phenomenon, meaning the waiting phase, when the acid actively affects scale. Do not turn off the device at this time, even if it seems to be “hanging”.
☑️ Automatic cleaning algorithm
After the cycle with the solution is completed, the machine will ask to pour clean water for the final washing. This step is critical: remove all acid residues from the internal circuits. It is usually required to drive a full reservoir of clean water through the system until the indicator goes out.
⚠️ Attention: Never interrupt the automatic midway cycle. If you turn off the machine during the waiting or washing phase, the acid residue will remain in the boiler, which can lead to corrosion and unpleasant taste in future cups.
Manual cleaning of the brewing block and capuchinator
While the inner tubes are cleaned of scale, the outer and mechanical parts require the removal of the coffee oils. The brew group is the heart of the coffee machine that comes into contact with ground coffee. In models Krups It is often removable, which greatly facilitates the care.
To remove the block, open the service door (usually on the side or front). Carefully press the locking levers and pull the block on yourself. Don’t put too much effort into it; if it doesn’t go, you may not have fully unlocked the mechanism. Wash the unit under warm running water without using detergents.
Pay special attention to mesh filters and rubber seals. With an old toothbrush, you can gently remove stuck coffee particles. Allow the unit to dry completely in air before installing it back. A wet block can lead to the clumping of fresh coffee and disruption of the brewing process.
The cappuccinator (panarello) also needs regular cleaning. Milk fat quickly freezes and clogs thin holes. Disassemble the nose, if the design allows, and soak the parts in a warm solution of dishes or a special tablet for cleaning the milk tract.
What to do if the block is not inserted back?
If the block does not stand in place, do not press. Check if the guides are turned over. Sometimes you need to slightly turn the block or press the central piston to get it into its original position. Also make sure there is no debris left inside the car body.
Comparison of cleaning and decalcination products
Choosing the right chemistry is a matter of safety for your equipment. There are many products on the market, but not all of them are equally effective and safe for specific models. Krups. It is important to distinguish between scale removal (acid) and oil removal (alkaline or enzymatic).
The use of inappropriate substances may damage the boiler aluminum alloys or rubber seals. Below is a comparative table of popular types of funds.
| Type of instrument | Core component | Frequency of use | Risks of overdose |
|---|---|---|---|
| Liquid decalcinator | Organic acids | Every 2-3 months | Residual taste, if poorly washed |
| Scaling pills | Sulfamic acid | On the indicator. | Unsolved particles can clog valves |
| Oil pills | Sodium percarbonate | Once a week / 200 cups | Excessive foam, possible overflow of the pallet |
| Citric acid | Natural acid | Not often recommended | Can damage rubber seals at high concentrations |
Specialized oil purification tablets are often used in a coffee-free washing mode. They effectively break down fats that are not dissolved by water. After this procedure, be sure to conduct a cycle of pouring clean water to remove the remnants of the chemistry.
Combining different types of cleaning products in one cycle is prohibited. First, decalcination is always carried out, then (on another day or after a thorough washing) - removal of oils.
Frequent errors in Krups maintenance
Even experienced users sometimes make mistakes that can shorten the life of a coffee machine. One of the most common is the use of acetic essence. Vinegar is too aggressive for internal components and leaves a persistent smell that is extremely difficult to remove from plastic tubes and boilers.
Another mistake is to ignore the replacement of water filters. If you use filter jugs or built-in cartridges, they need to be changed strictly according to the schedule. The expired filter not only does not purify the water, but also becomes a source of bacteria and secondary pollution.
Some users try to save money by pouring distilled water into the tank. This is not worth doing: the distillate is devoid of minerals that are necessary for a water hardness sensor to work properly. The machine may misidentify the need for decalcification or produce errors.
- 🚫 Do not use abrasive sponges to clean the outer surfaces – they will leave micro-scratches.
- 🚫 Do not attempt to disassemble the hydraulic unit without special skills and tools.
- 🚫 Don’t leave water in the tank for weekends or holidays – it can bloom.
⚠️ Attention: Technical specifications and service requirements may vary depending on the particular series of coffee machines. Always check the official documentation that comes with your device, as design features of the models may change.
FAQ: Answers to popular questions
Can I use citric acid instead of a special remedy?
Technically, this is possible, but not recommended by the manufacturer. Citric acid is less predictable in reaction with metals and may require more thorough washing. In addition, the acid crystals may not dissolve completely and damage the pump. It is better to use certified liquids.
How often should a Krups coffee machine be cleaned?
The frequency depends on the hardness of the water and the intensity of use. On average, decalcification is carried out every 2-3 months or after preparing 200-300 cups. Cleaning the brewing block from oils is recommended once a week if you drink coffee daily.
What to do if the coffee is not good after cleaning?
Most likely, there are residues of cleaning products in the system. It is necessary to carry out an additional cycle of washing with clean water (without coffee and without chemistry). Also check if the dispenser holes are clogged with dried coffee residues that may have soaked during cleaning.
Why does the coffee machine ask for decalcification immediately after the new one?
This may indicate a faulty water hardness sensor or a failure in the electronic control unit. Try resetting to factory settings and setting the stiffness level again according to the instructions. If the problem persists, a diagnosis is required in the service center.
The secret of the perfect foam
After each cleaning, give the car a rest and make 2-3 blank water spills. This will stabilize the boiler temperature and remove the last air plugs, which will provide a tight cream in the first cup.
Compliance with these simple rules will allow your coffee machine to be used. Krups It has been working as new for many years. Regular care is not just a recommendation, but a necessity to preserve the quality of the drink and the health of the equipment itself. Remember that (problem prevention) is always cheaper and easier than treating a breakdown.
