If you treat your pool with salt, you know that the electrolysis cell plays a central role in water disinfection. It's what converts salt into active chlorine, thereby keeping the water clear, healthy, and well-treated. But over time, this cell can become fouled or show signs of weakness. It then becomes crucial to know when a simple cleaning is enough... or when a replacement is necessary.
Signs of wear or scaling in the cell
Several clues can indicate that your electrolyzer cell needs cleaning or replacement. The first is a noticeable drop in chlorine production, often accompanied by cloudy or unstable water, despite correct chemical balance parameters. This deficit can manifest gradually or suddenly.
Error messages on the electrolyzer control unit should also be monitored, particularly codes related to a lack of production or detection of an inactive cell. Finally, a visual inspection may be enough to observe the presence of limescale deposits on the titanium plates. These mineral formations, common in hard water areas, hinder the proper functioning of electrolysis.
Recommended frequency for cell maintenance
Regular cleaning of the cell helps maintain its performance and extend its lifespan. It is advisable to intervene:
- when the pool is put back into service,
- in spring; every two months during intensive use in summer;
- during winterization, before prolonged shutdown of the filtration system.
Cleaning consists of removing deposits using an appropriate solution, following the manufacturer's instructions. It is important to avoid prolonged contact with overly aggressive products, which could damage the plates.
If you have any doubts about the method to follow, we offer a detailed video tutorial to perform this operation correctly.
When should cell replacement be considered?
If, despite rigorous cleaning, chlorine production remains insufficient, or if anomalies persist on the control screen, it is likely that the cell is at the end of its life. Generally, the average lifespan of a cell is between 2 and 7 years, depending on the intensity of use and water quality.
Before any replacement, it is important to check the compatibility of the new cell with your existing electrolyzer. If the device is still under warranty, contacting our technical service can help identify the cause of the malfunction and propose a suitable solution.
Good practices for preserving the cell
Beyond regular cleaning, maintaining good water balance is a decisive factor. A stable pH (ideally between 7.2 and 7.4), a well-adjusted TAC, and controlled hardness significantly reduce the risk of scaling. It is also recommended to regularly check the salt level and avoid sudden variations in temperature or flow.
By ensuring rigorous maintenance and intervening at the first signs of failure, you optimize the efficiency of your electrolyzer and guarantee consistent water quality.
