How To Troubleshoot a Jandy AquaPure


AquaPure is a salt chlorine generating system used to sanitize your pool, using a closed-loop water-softening system. As with any electronic and mechanical systems, problems can occur. While some problems are technical enough that they require the attention of a qualified professional, others have a simple solution and you might be able to troubleshoot these yourself.

Low or No Chlorine

  • Add chlorine stabilizer as required. Chlorine stabilizer content should be 50 to 75 PPM. For every 50 pounds of salt, 1.25 pounds of stabilizer should be added.

  • Increase the system's daily operating time.

  • Increase chlorine production by pressing the "chlorine production rate adjustment" button.

  • Enable "boost" mode and run for 24 hours.

  • Press the "test salinity" button. If salinity is low, more salt may need to be added.

  • Clean the cell if it is dirty or clogged.

Screen is Blank

No "Cell On" Indicator

  • Ensure "chlorine production" setting is not set to "00%." Adjust to desired percentage.

  • Clean and/or unblock cell as required.

  • Plug in the "flow/temp/salinity" sensor.

"No Flow" Indicator Stays On

  • Unclog the strainer baskets if necessary.

  • Correctly align all valves.

  • Clean or unclog filter if required.

  • Plug in the "flow/temp/salinity" sensor.

  • Remove the "flow/temp/salinity" sensor. Clean the sensor and reinstall.

Tips & Warnings

  • Regular cleaning and maintenance of the system will help prevent problems.
  • Do not attempt to access the electronic or mechanical components of the system.
  • Care must be taken when adding chlorine stabilizer. Follow the manufacturer's guidelines.
