Salt cells are an essential component of saltwater pools. They help in the production of chlorine which is necessary for sanitizing the pool water. However, like any other equipment, salt cells can go bad over time. Knowing when a salt cell is bad is crucial as it can save you from costly repairs and replacements. In this article, we’ll explore the signs that indicate a bad salt cell and how to fix the problem.
What is a Salt Cell?
Before we dive into the signs of a bad salt cell, it’s essential to understand what a salt cell is. A salt cell is a device that uses electrolysis to break down salt molecules into sodium and chloride ions. The chloride ions combine with water to form hypochlorous acid, which is a potent sanitizer that kills bacteria and algae in the pool water. Salt cells are installed in-line with the pool’s filtration system, and they require a steady flow of water to function correctly.
Signs of a Bad Salt Cell
1. Low Chlorine Levels
Low chlorine levels in your pool water are a clear signal that your salt cell may be bad. When the salt cell is functioning correctly, it should produce enough chlorine to maintain a consistent level in the pool. If your pool water is consistently low on chlorine, even after adjusting the settings on your salt cell, then it’s time to check if the cell is faulty.
2. High Salt Levels
Another sign that indicates a bad salt cell is high salt levels in the pool water. When a salt cell is functioning correctly, it should produce chlorine without increasing the salt levels in the pool water. However, if you notice a sudden spike in salt levels, it could mean that the cell is not working correctly.
3. No Chlorine Production
If your salt cell is not producing any chlorine, then it’s a clear indication that something is wrong. When a salt cell is working correctly, you should be able to see bubbles forming near the cell’s plates. If there are no bubbles, it could mean that the cell is clogged, or the plates are coated with calcium buildup.
4. Error Codes
Most modern salt cells have built-in diagnostic tools that can detect any faults in the system. If your salt cell is displaying an error code or blinking lights, then it’s time to check the manufacturer’s manual for troubleshooting steps. In most cases, error codes indicate that there is an issue with the cell’s settings, or it could be a more severe problem, such as a defective cell.
How to Fix a Bad Salt Cell
If you suspect that your salt cell is bad, the first step is to clean it thoroughly. Calcium buildup and other debris can accumulate on the cell’s plates, which can affect its performance. You can use a mixture of water and muriatic acid to remove the buildup. However, be sure to follow the manufacturer’s instructions carefully to avoid damaging the cell.
If cleaning the salt cell doesn’t solve the problem, then it’s time to replace the cell altogether. Salt cells have a lifespan of around three to five years, depending on usage, so it’s essential to keep track of when you installed the cell. Replacing the cell is a relatively simple process that can be done by a professional or a DIY enthusiast.
Conclusion
In conclusion, knowing when a salt cell is bad is essential for maintaining a healthy and clean pool. Low chlorine levels, high salt levels, no chlorine production, and error codes are all signs that indicate a bad salt cell. Cleaning the cell is the first step in fixing the problem, but if that doesn’t work, then replacing the cell is the best option. By keeping your salt cell in good condition, you can enjoy a safe and enjoyable swimming experience.

Frequently Asked Questions about How Do You Know When A Salt Cell Is Bad?
What is a salt cell?
A salt cell is a component in a saltwater pool system that generates chlorine to sanitize the water. It works by converting salt into chlorine through a process called electrolysis.
How do I know if my salt cell is bad?
There are several signs that your salt cell may be failing, including a decrease in chlorine production, an increase in pool algae or cloudy water, or an error message on your pool system’s control panel. If you suspect your salt cell is bad, it’s best to have it inspected by a professional.
Can a bad salt cell be repaired?
In some cases, a salt cell can be repaired if the issue is minor, such as a clogged cell or a broken wire. However, if the cell is corroded or damaged beyond repair, it will need to be replaced.
How often should I replace my salt cell?
The lifespan of a salt cell varies depending on the manufacturer and usage, but most cells last between three and seven years. It’s important to monitor your cell’s performance and replace it before it fails completely to ensure proper pool sanitation.
