Regular maintenance of automatic coffee machine Nivona It is a critical condition for the preparation of high-quality espresso and long-term service of the device. Owners often neglect the scale removal procedure or washing the brewing block, which eventually leads to expensive repairs. In this article, we will discuss in detail how to clean a Nivona coffee machine with your own hands, using the right means and sequence of actions.
Ignoring the device signals about the need for maintenance can lead to a decrease in pressure in the system and a deterioration in the taste characteristics of the drink. Coffee butters, accumulating in the brewing block, oxidize and give coffee an unpleasant bitterness. Timely cleaning avoids these problems and maintains the factory warranty for the equipment.
The maintenance process is divided into several key stages: cleaning the brewing unit, washing the water supply system and removing scale from the boiler. Each step requires specific actions and, in some cases, the use of specialized liquids with citric acid or sulfamine basewhich are safe for internal seals. Below we will look at each step in detail.
Signals for cleaning and preparation
Modern models Nivona equipped with a smart monitoring system, which itself informs the owner of the need for service procedures. Different symbols may appear on the display, indicating that it is time to act. Usually it is a flashing icon of a drop, watering or the inscription "Clean".
If the machine began to make unusually loud sounds when the pump is running or the cooking time of one portion has increased noticeably, this is a sure sign of clogging the hydraulic system. Scale. narrows the passage channels, causing the heating element to work with increased load. In this case, you should not wait for the symbol to appear on the screen - it is better to start the decalcination process immediately.
Before any manipulations, the workplace must be prepared. You will need a water drain capacity of at least 1.5 liters, soft fabric without pile and warm water. Also make sure there is no old coffee left in the water tank that could ferment.
⚠️ Warning: Never attempt to disassemble the casing of a coffee machine or remove the brewing block if the lock indicator is on. This can lead to the breakdown of the gears of the drive mechanism.
Cleaning of the brew unit (Brew Unit)
The brewing block is the heart of your coffee machine, where the direct brewing of the grain takes place. It is here that the remains of ground coffee and fatty deposits most often accumulate. For models Nivona system Easy CleanIt allows you to remove the block without using tools.
To remove the module, open the service door and press the locking button (usually red), after which gently pull the block over yourself. It is important to do this smoothly so as not to spill dry residues of coffee inside the car body. If the block is stuck, check if the machine is in standby or heating mode.
Washing should be carried out under a stream of warm water with a temperature of about 40-50 degrees. Using hot water can deform plastic elements, and cold water can not effectively dissolve coffee fats. Cleaning supplies dishwashers are strictly prohibited, as they wash off special lubrication from the guides.
- 🚿 Rinse the block with warm water, removing visible coffee residues.
- 🧽 Gently wipe the mesh filters with a soft brush without damaging them.
- 🔍 Check the rubber seals for cracks or plaque.
- 💧 Allow the unit to dry completely at room temperature before installation.
After drying, the block must be set back to a characteristic click. Make sure it stands up straight and does not prevent the service door from closing. Regular cleaning of this unit is the key to stable pressure when preparing espresso.
Lubricate the guides of the brewing block with food silicone lubricant once every 3-4 months so that the mechanism moves silently and easily.
Decalcination procedure (scaling removal)
Decalcination is the process of removing mineral deposits (scale) from the boiler and hydraulic system. Hard water is the main enemy of coffee machines. For the procedure you will need a branded tool Nivona Descaler or its qualitative analogue based on organic acids.
Start the cleaning program by going to the settings menu. The path may differ from one model to another, but it usually looks like this: Menu → Care → Decalcination. The machine itself will offer to pour the product into the water tank and add water to the maximum mark. Follow the proportions indicated on the packaging.
During the process, the machine will periodically stop and make sounds. This is the normal operation of the pump, which runs the solution through the system. Do not interrupt the process or turn the device off the network until the program is complete. The entire cycle can take 20 to 40 minutes depending on the model.
☑️ Checklist before launching decalcination
After the cycle is completed, the machine will ask to wash the system several times with clean water. This is necessary to remove the residues of acid and dissolved scale. Neglecting this stage can lead to a sour taste in the first cups of coffee.
Table of Nivona maintenance facilities
Choosing the right chemistry is half the success. The use of aggressive acids, such as acetic or salt acid, can damage aluminum and plastic parts of internal systems. Below is a table of recommended tools and their characteristics.
| Type of instrument | Appointment | Frequency of use | Features |
|---|---|---|---|
| Liquid cleaner (Descaler) | Removal of scale from the boiler | By signal or once in 2-3 months. | Safe for seals, odorless |
| Cleaning tablets (Cleaner) | Dissolving coffee oils | Once a week or 200 cups | Launched through "Cleanup" mode |
| Silicone lubricant | Care for the brew block | Once in 3-4 months | Foody, odorless and tasteless. |
| Water Filter (NICF) | Water softening | Every 2 months | Reduces the frequency of decalcination |
Use of original consumables Nivona It ensures compatibility with the materials used in the production of your model. Cheap analogs may contain abrasive particles or too aggressive components.
Can I use citric acid?
Use of pure citric acid is possible, but requires accurate dosage. Concentrated solution can damage plastic tubes and rubber seals inside the machine. It is better to use ready-made professional tools, where the concentration has already been selected by engineers.
Washing of the milk supply system
If your model Nivona cappuccinated One TouchTaking care of the milk contour becomes a daily necessity. Milk is an ideal medium for the reproduction of bacteria that can be dangerous to health.
Automatic washing is activated at each turn on and off of the machine. However, once a week it is recommended to carry out a deep cleaning. To do this, remove the milk container and disassemble it according to the instructions, washing all parts with warm water with a soft detergent.
The milk supply also needs attention. Lower the end of the tube into a container of clean water and start the mode of supplying steam or hot water. This will help to wash the milk from the internal canals. Do not leave milk in the container overnight.
⚠️ Never immerse the base of a milk container (where electronic contacts or machinery are located) completely in water unless it is provided by the design of a particular model.
For disinfection, special foaming tablets can be used to clean the milk systems. They effectively break down protein compounds that are difficult to remove with ordinary water. After using the chemistry, be sure to thoroughly rinse the system with water.
Cleaning coffee cake and tray
The drop tray and the cake container are the nodes with which the user interacts most often. Despite the simplicity, there are also nuances. The container for spent coffee should be shaken out regularly, but wash it with soap at least once a week.
If the cake in the container looks too watery or, conversely, crumbly, this may indicate the need to adjust grinding or pressure. However, often the reason lies in clogged drainage holes of the tray. Wash the tray under a strong pressure of water, using a brush for hard-to-reach places.
The water pan also needs attention. Mucus or mold may form at the bottom, especially if the car has been idle for a long time. Wash the pallet with a dry cloth after each emptying. This will prevent the appearance of an unpleasant smell of "mustiness" in the kitchen.
- 🗑️ Shake the cake when the indicator shows a full container.
- 🧼 Wash the tray and container with warm water with a soft detergent.
- 👀 Check the drainage hole in the center of the tray for blockages.
- 🌬️ Allow all plastic elements to dry before assembly.
Keeping clean in this area prevents the reproduction of insects and bacteria. In addition, the neat appearance of the coffee machine pleases the eye and creates the mood for the morning ritual.
Regular cleaning of external elements and trays takes 2 minutes a day, but prolongs the life of internal nodes for years.
Frequent errors in service
Many users make common mistakes in trying to save time or money. One of the most common is the use of distilled water. Contrary to popular belief, distillate does not contain minerals necessary for the correct operation of water hardness sensors in some models. Nivona.
Another mistake is ignoring the replacement of the softener filter. Even if you use bottled water, the filter helps stabilize the pH and trap fine mechanical impurities. A filter that is replaced in time can become a source of contamination.
Also, do not use abrasive sponges or aggressive household chemicals (chlorine, acetone) to wipe the body and display. This will lead to the appearance of micro scratches and clouding of the plastic. Use only soft flannel fabrics.
What if the machine says "Fill the tank" when it's full?
Most likely, holes were clogged at the bottom of the tank or the magnetic float failed. Try washing the tank and cleaning the holes with a thin needle. If it doesn’t work, check the integrity of the magnet in the float.
Can I skip the rinse stage after decalcination?
Absolutely not. Residues of scale removal products will spoil the taste of coffee and can be harmful to health. The machine itself controls the amount of washing water, trust the algorithm.
How often should the stained block be removed?
The recommended frequency is every 3-4 months or after each 5th cycle of decalcification. Use only food-grade silicone lubricant that has no odor.
Why did the coffee get worse after cleaning?
There may be residues of cleaning agent in the system. Try to drink 2-3 cups of hot water without coffee. Also, the cause may be a knocked down grinding setting if you accidentally hit the regulator.
Is it safe to use pills from other brands?
If the tablets are certified for automatic coffee machines and do not contain chlorine, their use is permissible. However, the original pills Nivona It is compatible with your model materials.
