Zodiac Ei Chlorinator Output Fault - How To Fix It?

Salt chlorine generators are the primary source of sanitation for saltwater swimming pools.

These machines use the salt in your pool’s water to produce chlorine that keeps your pool clean and free of bacteria and algae. Occasionally, you may experience chlorinator output faults that indicate your machine is not adding enough chlorine to your pool.

In this guide, we will cover troubleshooting information for your Zodiac Ei Chlorinator so that you can make any necessary adjustments to your machine and get it working properly!

Troubleshooting Zodiac Ei Chlorinator Output Fault

Fixing Issues With Your Chlorinator

Disconnected Salt Cell

The biggest cause of the Zodiac Ei Chlorinator producing inadequate amounts of chlorine is a disconnected salt cell. To remedy this, ensure that your chlorinator’s cables are appropriately connected to the salt cell as outlined in your product manual.

These cables are typically not meant to be submerged. If they have become wet, disassemble your salt cell and allow these cables to dry before reconnecting them.

Broken Salt Cell

When trying to fix salt chlorinator output, you should try increasing your machine’s chlorine production level manually by running it at 100% capacity.

This both increases chlorine production and functions as a salt cell test. In this setting, you should see mist coming off of your chlorinator cell if it is functioning properly. If you do not notice this, your salt cell may need to be replaced.

Filter & Water Chemistry Problems

The next step you should take to fix issues with your chlorinator output is to backwash your pool’s filter. This helps dislodge any debris chunks that could impact the flow of water that passes through your chlorinator.

You should also test your pool’s salt levels. If they are reading on the low end of your device’s optimal operating range of 4,000-10,000 ppm, adding more salt to your pool can also help fix your Zodiac Ei Chlorinator’s output fault.

If your pool’s chlorine level is only slightly low, consider using the boost or super-chlorination settings on your chlorinator. If you have already tried these settings, you can also increase the chlorinator’s timer period to improve chlorine production.

Other Factors That Affect Chlorine Levels

Because many other factors can affect your pool’s chlorine levels, it is essential to determine the cause of the low chlorine readings you may be experiencing. In some cases, chlorine tests may show low results even when your chlorinator is working as intended.

Some other factors that can cause your pool’s chlorine to test at lower levels than normal include hot summer weather, poor water filtration, frequent use of the pool, or a high number of swimmers.

If your filter needs to be backwashed, this can also negatively impact your pool’s free chlorine levels.

On a hot summer day, chlorine levels can drop by up to 90% as a result of rising water temperatures and exposure to the sun. Consider testing your pool’s chlorine levels early in the morning to see if they are still reading below the recommended range of 2-4 ppm.
