How to Troubleshoot an Ozone Generator Spa


Spas installed with an ozone generator operate like a normal spa or pool with the exception of not needing regular sanitizer treatments. The ozone generated in the spa sanitizes the water, leaving only the need to properly balance the other water levels and maintain the spa equipment. Troubleshooting an ozone generator spa involves testing the spa water for unbalanced water levels, correcting any unbalanced water levels and searching the ozone generator for any leaks or suction problems.

Things You'll Need

  • Test kit
  • Water balancers
  • Ozone generator tubing
  • Gather a sample of the ozone generator spa's water in a test container or bottle. Test the water's pH and hardness levels using a test kit. Alternatively, take the sample to a local pool professional for testing. Record the results.

  • Drain the spa partially if the hardness level is over 300 ppm (parts per million). High hardness results in milky water and scale deposits forming on spa surfaces. Repeat the draining process until a hardness level in the 100- to 300-ppm range is reached.

  • Add a pH decreaser or increaser to the spa water until a level between 7.4 and 7.6 is reached; pH measures the acidity of the spa water. PH levels that are too high on the scale result in cloudy water, and levels that are too low on the scale result in rust or other corrosion damage in the spa equipment.

  • Clean out the spa's skimmer basket. Clear away any debris or other obstructions from the spa's return lines and main intake like. A full skimmer basket or clogged plumbing lines cause water to not move through the pool plumbing correctly, causing the ozone generator to not operate properly.

  • Examine the ozone generator's tubing for holes or severe folds. Replace any damaged sections of the tubing with a replacement. Leaking tubing causes a suction leak in the ozone generator system, preventing proper ozone generation in the spa.

Tips & Warnings

  • Regularly check your spa water's chemical levels. Properly maintained water levels can lengthen the life of your spa and spa equipment.
