A clicking sound from a water purifier is a common problem. Do you know the cause and how to fix this? Let's explore the details in the article below from Dien May XANH's Kitchen Tips section!
1. What does a clicking sound from a water purifier mean?
A clear and characteristic sign of a malfunctioning water purifier is a clicking sound coming from inside the filtration system. This sound can be loud or soft depending on the cause of the problem.
During operation, the water purifier may also produce sound due to the pump's operation. However, these sounds are usually very quiet and not too noisy. Furthermore, when the water tank is full, the water purifier will automatically stop operating and the sound will also stop.
However, if you notice that your home water purifier is making a loud, intermittent clicking sound, or if the machine is operating erratically, with no purified water flowing from the tap or a very weak flow, and a larger than normal amount of wastewater, then your water purifier may be malfunctioning.
2. Causes and solutions for a clicking water purifier
A clicking water purifier due to a faulty pump
The water pump is a crucial part of the water purifier, responsible for creating pressure to push water through the filter membrane, helping to effectively purify the water. When the pump is operating erratically or the water supply to the machine is weak due to insufficient power, users may hear strange noises from the water purifier. This sound is caused by air being pushed out of the system.
You can check the machine's condition as follows:
First, check if the inlet water valve is fully open.
Next, check the screws on the pump, ensuring they are tightened and not loose. If necessary, you can replace any loose screws with new ones to ensure proper stability.
Finally, bleed any trapped air from the pump head to restore the system's normal operation.
Clogged filter causing clicking noise in water purifiers
One of the causes of clicking noises in water purifiers could be that the filter cartridge has accumulated too much dirt after a period of use without being cleaned or replaced. The filter cartridge can become clogged with dirt, preventing water from flowing through the filter membrane and creating strong pressure, leading to the clicking noise you may hear.
If you believe the strange noise is due to a clogged filter cartridge, you should remove this part to check, clean, and replace the water filter cartridge if it's due for a regular replacement to ensure smoother machine operation.
Water purifier making clicking noises due to improper valve closure
Improperly closing the pressure tank valve after replacing the filter cartridge, leading to air blockage in the valve, is also a cause of clicking noises in the water purifier. When this happens, the water purifier may still operate but will not be able to produce purified water or wastewater.
To fix this problem, you can follow these steps:
After closing the pressure tank valve, gently tilt the water purifier system to the right to push the air out.
Turn on the water purifier and let water flow through the tap for about 1 minute.
Turn off the water purifier for 10 seconds.
Repeat the above process several times until you no longer hear the clicking noise from the water purifier.
Incorrect water supply location and source
Another possible cause of clicking noises in the water purifier could be a weak incoming water supply. When the water supply to the water filter is not strong enough or there is a leak, the water flow into the machine is uneven, causing air blockage in the filtration system. The installation location of the water filter can also affect the device's performance.
To resolve this issue, you can take the following measures:
Choose a location to install the water filter on a flat, stable surface and ensure the machine is not tilted or uneven.
Ensure a strong water supply to the water filter. Check the water pipes to ensure there are no obstructions causing blockages or leaks, thereby creating a smooth flow and preventing air blockage.
If the water pipes are too small, replace them with larger pipes to ensure a stronger water flow, thus helping the water filter operate more effectively.

Water purifier making clicking noises due to weak incoming water supply
When your water purifier makes clicking noises, the first thing to consider is the incoming water supply. You need to check if there are any problems with the water source, such as leaks, slow flow, or weak water pressure. Additionally, you can observe the water purifier's display; if there is a clicking noise, it will show an error code for you to identify and take corrective action.
Weak or insufficient incoming water supply can create a gap in the filtration system. This is also a cause of clicking noises in the water purifier.
You can take the following steps to fix the problem:
Immediately check the water pipes and see if there are any blockages or leaks due to the pipes being covered with algae or sediment.
