Signs Your Pool Chlorinator Cell Needs Replacing
Over time, the cell in your pool chlorinator will wear down and need to be replaced. Here are the key signs that it’s time for a new cell…

Tell tale signs your chlorinator cell needs replacing.
If you notice that your pool is no longer maintaining proper chlorine levels or your chlorinator is malfunctioning, despite regular cleaning, it may be time for a replacement.
These are the main signs that your chlorinator cell needs replacing:
- Low chlorine production: If your pool chlorinator isn’t generating enough chlorine, even when settings are correct, the cell may have lost its ability to effectively convert salt into chlorine. A buildup of calcium or other minerals could be restricting its function, so give it a good clean. If you’re not sure how, click the following link to learn how to clean a chlorinator cell. If cleaning it doesn’t help, it may simply be worn out.
- Error messages: Many chlorinators display error codes when there’s an issue with the cell. Common codes include “Low Salt” or “Cell Failure.” If troubleshooting doesn’t resolve the issue, a new cell might be needed.
- Poor water quality: Cloudy or green water is a sign that the chlorinator isn’t producing enough chlorine. If you’ve already cleaned the cell and checked the salt levels and settings, a faulty cell might be the cause.
- Poor Water Flow: Calcium buildup can aslo restrict water flow, so clean the cell to see if that helps. If cleaning the cell doesn’t help, then you may need to replace it.
- Physical damage: If the chlorinator cell is cracked, corroded, or showing signs of significant wear, it’s time to replace it. Even small cracks can lead to leaks or diminished performance.
Prompt replacement of a faulty or worn out cell will ensure your chlorinator continues to produce high-quality chlorine, thus keeping your pool clean and safe for swimming.
Which KChlor Pool Chlorinator is best for you?
It depends on the size of your pool. To calculate how many litres are in your pool simply multiply the length by the width and then the average depth (depth at the deep end plus depth at the shallow end divided by 2).
Even if your pool is not rectangular in shape, this is still a good way to measure it, as it is always a good idea to overestimate the pool size anyway, so the chlorinator you choose does not have to work too hard to maintain it. Therefore any curves in the pool can be ignored.

How Often Should You Replace Your Pool Chlorinator Cell?
A key part of keeping your pool chlorinator running smoothly is replacing the chlorinator cell when needed. Over time, the cell can degrade due to mineral buildup and normal wear and tear. How often should you replace it? The typical lifespan of a chlorinator cell is 3 to 7 years, depending on usage and maintenance.
Regular maintenance, such as cleaning the cell every 3 to 6 months, can help extend its lifespan. However, if the cell shows signs of corrosion or damage, it’s best to replace it to ensure your pool stays clean and safe. If your pool chlorinator is the KChlor brand, buy your replacement K-Chlor cells here.
