Salt Chlorinator Problems – Repair or Replace?

zodiac-jandy-aquapure-ei-salt-generator-smlSalt Chlorine Generators do require some maintenance and repair. The salt cell will eventually lose performance and the controller circuit boards can develop problems over time.

New technology in salt systems may also sway your decision to repair or replace your salt chlorinator. Newer models self-clean and self-diagnose and other advanced features.

Chances are, at some point you will face an expensive repair to your salt system, I’m talking about either a new salt cell, or a new control board. Both of these repairs can approach half the cost of a new system.

How do you know if you have a salt chlorinator problem? Usual symptoms are low chlorine output, as determined by your water tests, indicator lights or error codes flashing on the control box, or no lights at all.

Troubleshooting a Salt Chlorinator

plug-for-salt-systemFirst, check power. If your salt cell is plugged into an GFI outlet, make sure that the test button is not popped, or tripped. If your salt system is hardwired, variations in voltage could cause the controller to go a little haywire.

Check your water balance. Especially your pH,pool-testing and your Cyanuric Acid levels. High pH and low CYA can make it hard for chlorine to be effective. Keep a pH level of 7.2-7.6, and your level of CYA (or Stabilizer), at 30-50 ppm, to reduce the workload on your salt cell. Using the salt cell too much increases scale, and may cause premature cell failure.

New Salt Systems can reverse polarity to slough off accumulated scale. Other units may have an indicator light to let you know when the cell needs to be manually cleaned. Older salt systems have neither, and require periodic inspection and cleaning.

Buy New or Repair Old?

Back to the original question. Well, if my troubleshooting tips didn’t help you, the next step might be to assess the likely parts needed to repair the salt system, so you can determine the probable repair costs, to weigh against the cost of a new salt chlorine generator.

If the salt system is still within the warranty period, by all means, get on the phone with the manufacturer’s support reps, for some advanced troubleshooting, or warranty service.

Most salt cells last 3-5 years, depending on the salt system, and situational factors. The control boards used can last 3x as long, even in the outdoor environment, or they could fall victim to insect, power or moisture issues.

If you’ve invested too much money into your current salt system, and are finding it unreliable, perhaps switching brands would be appropriate. Or, if your system is over 10 years old, you may enjoy the features and benefits available on our newest salt systems for pools.

Salt Chlorinator Problems – Repair or Replace? — 22 Comments

  1. Hi there-

    We have a Jandy AquaPure APURE35 that appears to have no power to it. There are no lights on it at all. I believe it is wired to the pump and the pump is running with no issues. Any ideas? It is 5 years old so not sure if it just died!

    • Hi Lori, no lights on at all could be a power supply or transformer failure, or a circuit board failure. Or a power cable failure, or it could just be a fuse, or a relay… The problem lies where the power dies… if you have a multimeter (and aren’t afraid to use it), you can troubleshoot where the incoming power is stopping. It may have just died, which could be expensive, 5 years is about the right time for that, but hopefully something easy. Check that the GFI test button is not popped on a wired outlet, if you have one, and that the power is reaching the control unit.
