Modern refrigerators with a water and ice supply system require regular maintenance to maintain the quality of drinking water. If you notice a change in the taste of the liquid or a decrease in pressure, this is a sure sign that it is time to service the filtration system. Ignoring this process can lead to the accumulation of bacteria and contaminants, which will spoil the taste of drinks and may damage the feeding mechanism.
The replacement process cartridge usually does not require calling a technician or special tools. Most manufacturers equip their models Side-by-Side or French Door with convenient systems for quickly changing consumables. In this article, we will look in detail at how to carry out the procedure correctly so as not to damage the seals and avoid leaks.
Before starting work, it is important to determine the type of cleaning system installed in your model Bosch, Samsung or LG. The designs may differ in location and method of fixation, but the general principle remains similar. Proper preparation will allow you to complete all steps in 5–10 minutes without unnecessary stress and the risk of damaging your equipment.
Types of filtration systems in refrigerators
The design of the cleaning element directly depends on the model and year of manufacture of your refrigeration unit. Understanding the type of system will help you purchase the correct replacement and avoid installation mistakes. In the modern household appliances market, there are most often three main location options.
The first and most common type is internal filterslocated in the upper right corner of the refrigerator compartment. They are cylindrical cartridges that are inserted into a special compartment. To replace them, you usually need to turn the element counterclockwise 90 degrees, after which it can be freely removed.
The second option is systems integrated into the bottom part refrigerator, often hidden behind a decorative grille in the base. Such models are typical for some series Whirlpool and GE. The third type is external inline filters, installed on the water pipe before entering the refrigerator. They are not included in the basic package, but can be installed additionally to improve water quality.
- 🔹 Cylindrical cartridges at the top of the chamber are the most popular and convenient option.
- 🔹 Bottom systems require tilting or removing the protective panel for access.
- 🔹 External main filters are installed separately on the water supply.
⚠️ Attention: Before purchasing a new cartridge, be sure to check the model number of your refrigerator with compatible filter articles. The use of non-original or unsuitable parts can lead to leaks and damage to the water supply system.
Necessary tools and preparation
Although the replacement procedure itself is simple, proper preparation of the workplace will save your time and nerves. You don't need a complex professional tool, but having a few household items will be extremely useful. This is especially true if the previous owner or you yourself have not changed the cartridge for a long time, and it could have “stick.”
First of all, prepare a container to collect water. When removing the old element from the system, residual liquid will leak out, the volume of which can reach 200–300 milliliters. You will also need a clean towel or rag to quickly remove drops from the floor or shelves of the refrigerator.
If the filter has been installed for a long time and is difficult to turn, you may need a special puller, which often comes with a new cartridge, or ordinary pliers with soft jaws. However, they must be used with extreme caution so as not to damage the plastic casing.
☑️ Preparing to replace the filter
Step-by-step instructions for replacing the cartridge
The replacement process can be divided into several sequential ones stages. Strict adherence to the algorithm of actions guarantees tight connections and proper operation of the system after installing a new element. Take your time, perform all movements smoothly.
First you need to turn off the water supply. Locate the valve on the water pipe that feeds the refrigerator and turn it to the “closed” position. This will prevent pressurized water from splashing out when you remove the cartridge. If there is no separate valve, just be prepared to quickly plug the hole.
Open the refrigerator door and find the compartment with the filter. Depending on the design, press the release button or simply grasp the end of the cylinder. Turn the filter counterclockwise. Usually it is enough to make a quarter turn (90 degrees) for the latches to disengage.
After removing the old element, carefully inspect the seat. Remove any possible contamination and check the condition of the rubber seals. Prepare the new cartridge according to the instructions: remove the protective caps and, if necessary, lubricate the O-rings with food-grade silicone (although more often they are already lubricated).
⚠️ Attention: Some filter models require pre-washing. Carefully read the instructions on the packaging of the new cartridge - you may need to fill it with water several times and drain it before installing it in the refrigerator.
Insert the new element into the socket and turn it clockwise until a characteristic click or marks match Lock and Unlock. Don't try too hard; If the filter does not stand up, check the correct rotation angle. After installation, open the water supply valve and check the connections for leaks.
What to do if the filter does not turn?
If the cartridge is stuck, do not use brute force. Try lightly tapping the end of the filter with your hand or use a special puller ring, which is often included. You can also try heating the plastic case with a hairdryer at minimum temperature for 10-15 seconds to make the plastic more elastic. If all else fails, it is better to call a specialist so as not to break the inlet pipe.
Comparison of popular filter models
Choosing the right consumables is the key to clean water. There are many options on the market that differ in resource, degree of purification and compatibility. Below is a table to help you navigate the main characteristics of common types of cartridges.
| Filter type | Resource (liters) | Service life | Compatibility |
|---|---|---|---|
| Standard coal | 300–400 l | 6 months | Bosch, Siemens |
| Improved (Plus) | 500–600 l | 6–12 months | Samsung, LG |
| Antibacterial | 300 l | 6 months | Whirlpool, Indesit |
| Trunk (Inline) | 1000+ l | 12 months | Any models |
When choosing, pay attention not only to the brand, but also to the labeling. Original products often have security holograms and unique codes for authentication on the manufacturer's website. Counterfeit products can not only purify water poorly, but also emit harmful substances during operation.
Bleeding the system and resetting the indicator
After physically installing a new cartridge, the system requires bleeding. There is air inside the new filter and lines that needs to be forced out. If this is not done, the dispenser will “spit” and the water may flow in jerks.
Take a large container (3-5 liter bucket or pan) and start draining the water through the dispenser. The process may take several minutes. Pause if the pressure becomes weak, allowing the system to refill. Usually it is necessary to drain about 4-5 liters to completely remove air pockets and carbon dust.
Most modern refrigerators are equipped with an electronic filter status indicator. After replacement, you must manually reset the counter so that the system starts counting again. This is usually done by long pressing (3-5 seconds) on the button Filter Reset or through the settings menu Settings → Maintenance.
If the indicator continues to turn red or flash after a reset, check the tightness of the compartment cover (if there is one) and make sure that the filter is turned all the way to the locked position. In some models Smart refrigerators replacement notification comes directly to the smartphone.
Frequent errors and troubleshooting
Even when following the instructions, users sometimes encounter problems. Most often they are associated with inattention to installation details or the use of low-quality components. We will analyze typical situations so that you can quickly eliminate them.
If after replacement you hear noise or humming of the pump, this may indicate airing in the system. Repeat the bleeding procedure more thoroughly. If water drips from under the filter, the rubber O-ring may be pinched, dirty, or misaligned. Remove the cartridge, lubricate the ring and reinstall it.
It happens that the replacement indicator does not reset. Try unplugging the refrigerator for 2-3 minutes. This will reboot the management controller and once powered on the reset can be attempted again. In rare cases, it is necessary to replace the indication board itself, but this happens extremely rarely.
- 🔸 Water flows poorly: most likely, there is air in the system or the tubes are clogged with ice.
- 🔸 Strange taste: the new filter has not been washed enough or the cartridge has expired.
- 🔸 The indicator does not go off: try resetting through the menu or rebooting the device.
⚠️ Attention: The design and location of the controls may vary depending on the specific model and year of manufacture. If the described steps do not correspond to the interface of your device, refer to the manufacturer's official instructions or find a diagram for your specific series.
Questions and answers (FAQ)
How often should you change the filter in the refrigerator?
The standard replacement interval is once every 6 months or after filtration of 300–400 liters water. However, if you notice a change in the taste or smell of the water or a decrease in pressure, you should replace it immediately, regardless of the service life.
Is it possible to use a refrigerator without a filter?
Technically, the refrigerator will work, but we do not recommend operating the water supply system without a filter element. This can lead to clogging of thin tubes and valves with mechanical particles from the water supply, as well as the appearance of scale in the ice maker.
Why does the water taste strange after replacing the filter?
In the first hours of operation, a new carbon filter may give the water a slight aftertaste. This is fine. It is necessary to drain 5–10 liters of water. If the taste lasts longer, the cartridge may be defective or incorrectly installed.
Are universal filters suitable for my refrigerator?
Universal filters often require the use of special adapters (adapters). Although they are cheaper than the originals, the quality of cleaning and tightness of connections may be inferior. It is better to choose certified analogues, specially designed for your model.
