Coffee machines Polaris are deservedly popular due to the combination of affordable price and functionality. However, any mechanism that comes into contact with water and organic products requires regular maintenance. Ignoring cleaning leads to scale formation, clogging of pipes and deterioration in the taste of the drink. Timely decalcification extends the life of the heating elements and guarantees stable pressure when brewing espresso.
Owners of automatic models are often faced with a signal about the need for cleaning, which absolutely cannot be ignored. The process of removing deposits does not require complex engineering skills, but requires strict adherence to the sequence of actions. In this article, we will look at all the nuances of caring for your coffee maker so that it will delight you with ideal coffee for many years.
Signs of Cleaning and Preparation
Understand what's yours Polaris coffee machine urgent cleaning is required, based on a number of indirect signs. The water in your area may be hard, which accelerates the formation of limescale. Even if the machine does not beep, a visual inspection and the quality of the coffee will tell you about the condition of the internal system.
Pay attention to the following symptoms indicating contamination:
- 📉 The pressure of the stream has become weak, the coffee is dripping, but not flowing.
- ☕ The taste of the drink has changed, bitterness or sourness has appeared that is not characteristic of the grain.
- 🔊 The device makes louder sounds when heating water or pumping steam.
- ⚙️ The limescale symbol on the indicator lights up (often looks like a ladder or shower head).
Before starting the procedure, it is necessary to prepare a workplace and consumables. You will need a decalcifier. You can use specialized fluids from Polaris or proven analogues, as well as citric acid in the correct proportions. Find in advance a container with a volume of at least 1.5 liters to drain the water.
⚠️ Attention: Never use pure acetic acid or aggressive chemical solvents. They can damage the rubber seals and plastic parts of the internal line, which will lead to leaks.
It is also important to free up space around the device. The process may take from 30 to 60 minutes, during which the machine will operate in rinsing mode. Make sure the drip tray is empty and the water tank is clean and free of foreign objects.
Choosing a decalcifying agent
The quality of cleaning directly depends on the selected reagent. The market offers many options, but for technology Polaris Products based on organic acids are best suited. They effectively dissolve calcium carbonate without leaving a film on the walls.
Let's compare the main types of cleaners available on the market:
| Product type | Efficiency | Seal safety | Recommendation |
|---|---|---|---|
| Specialized liquid | High | Full | Recommended |
| Tablets for coffee machines | Average | High | Acceptable |
| Citric acid (solution) | Average | High | Budget option |
| Vinegar essence | High | Low | Not recommended |
If you choose citric acid, it is important to maintain concentration. A solution of 20-30 grams of powder per 1.5 liters of water is considered optimal. A solution that is too saturated can crystallize inside narrow tubes as it dries, creating an even more serious blockage than scale.
Specialized products often contain corrosion inhibitors and lubricants that are beneficial for the moving parts of the pump. By using branded chemicals, you minimize the risk of damage to internal components and maintain the warranty on the device.
⚠️ Attention: When using any chemicals, ensure good ventilation in the room. Acid fumes, even weak ones, can irritate the mucous membrane of the respiratory tract.
Automatic cleaning program (Decalcification)
Most modern models Polaris equipped with a built-in decalcification algorithm. It should be started strictly according to the instructions, since interrupting the process may disrupt the settings of the scale counter. The machine itself will alternate between supplying the solution and pausing to dissolve deposits.
The process is launched through a menu or a combination of buttons. Typically you need to hold down the steam button or dedicated clean button for 5-10 seconds. After entering the mode Decalcification, the device will ask you to pour the prepared solution into the tank.
Next, the system will begin to drive liquid through the boiler and brewing unit. It is important to monitor the liquid level in the pan and empty it on time. Do not try to speed up the process by adding fresh water ahead of time - this will disrupt the concentration of the active substance inside the system.
The machine may stop several times during the program. This is normal and necessary for a chemical reaction. At this time it happens scale dissolution on the heating element. Complete completion of the cycle is confirmed by a sound signal or the indicator switching to ready mode.
Interrupting the automatic cleaning program may result in residual acid remaining in the boiler, which will spoil the taste of the first coffees.
Manual cleaning of the brewing unit
Automatic rinsing does not remove coffee oils and ground bean residues that accumulate in the brewing unit. This unit is in cars Polaris often removable, which greatly simplifies maintenance. Regular mechanical cleaning prevents the appearance of mold and foreign odors.
To remove the unit, you usually need to open the service door and press the latches. Be careful not to damage the plastic guides. The removed mechanism should be washed with warm water without using detergents.
- 🚿 Rinse the block thoroughly under running water, removing visible coffee residues.
- 🧽 Use a soft brush to clean mesh filters and seals.
- 💧 Allow parts to dry completely at room temperature before installing.
It is recommended to lubricate the brewing unit with food-grade silicone no more than once a year or after each deep cleaning. This will ensure smooth operation of the mechanisms and reduce noise during operation. Avoid getting lubricant on parts that come into direct contact with the coffee.
☑️ Checklist for cleaning the brewing unit
If you notice that the rubber seals have lost their elasticity or are cracked, they need to be replaced. Operating the machine with worn rubber bands leads to a drop in pressure and water leaks into the pan.
Maintenance of the cappuccino maker and pipes
The milk frother is the place where bacteria most often grow due to milk residues. Milk fat quickly oxidizes and gives the drink a rancid taste. This unit should be cleaned immediately after each use, without delay.
Remove the outer tube of the cappuccino maker and rinse it with hot water. To clean the internal steam system, use the "Steam" function. Place the tube in a container of clean water and turn on the steam for a few seconds. This will clear the channels of any remaining moisture and milk.
If the plaque is old, you can soak the removable parts of the cappuccino maker in a warm solution of a special product. However, metal elements should not be kept in an aggressive environment for too long to avoid corrosion.
⚠️ Attention: Never immerse the main body of the coffee machine or the non-removable parts of the cappuccino maker in water. This will cause a short circuit and damage the electronics.
The secret of perfect foam
To obtain a thick and stable foam, use only cold milk with a fat content of 3.2-3.5%. Higher fat milk will be too heavy, and skim milk will not give the desired structure.
Regularly check the condition of the vent through which the steam escapes. It may become clogged with mineral deposits. To clean, use a thin needle or the special paper clip included in the kit, but be extremely careful not to widen the hole.
Completing the loop and checking the result
After completing all cleaning steps, it is necessary to perform a final rinse of the system with clean water. This will remove any remaining cleaning agent and dissolved scale. Run a full reservoir of fresh water through the machine in coffee brewing mode.
Visually assess the quality of the jet. It should be smooth, without splashing or pulsation. The outlet water should not have a chemical smell or taste. If you used citric acid, you may need to run 2-3 tanks of water to completely neutralize the taste.
Reassemble the car to its original condition. Make sure all removable parts are installed correctly and completely. Turn on the device and let it warm up. Now yours Polaris coffee machine ready to work in optimal mode.
Wipe the outside of the coffee machine with a damp microfiber cloth after each preparation. This will prevent the accumulation of fatty film and maintain the presentable appearance of the device.
Record the service date in your calendar or app. This will help you remember about the next procedure. Regularity is the key to the long life of your coffee maker.
Frequently asked questions (FAQ)
How often should you clean your Polaris coffee machine?
The frequency depends on the water hardness and intensity of use. On average, decalcification is carried out every 2-3 months or after preparing 200-300 cups. If the water is very hard, the interval is reduced to 1 month.
Can I use tablets instead of liquid?
Yes, you can, if the tablets are intended specifically for automatic coffee machines and dissolve completely. However, liquid products penetrate better into hard-to-reach areas of the system.
What should I do if the machine does not exit the cleaning mode?
Try unplugging the device from the outlet for 10-15 minutes, then plugging it back in. If the problem persists, the water level sensor or pump may be clogged, which requires service.
Is frequent use of citric acid harmful to the car?
If the correct concentration is observed (no more than 20-30 g per 1.5 l), citric acid is safe. However, frequent use of strong acids can wear out rubber seals over time, so it is better to alternate with mild special agents.
Why did my coffee taste bad after cleaning?
Most likely, there are cleaning agent residues left in the system. It is necessary to run 1-2 more full tanks of clean water through the machine. Also, the taste may change if you have not cleaned the brewing unit of coffee oils for a long time.
