Possible Causes
Expired corona discharge or UV ozonator, Cracked or kinked ozone tubing, Blocked ozone injector, Failed ozone check valve
How to Fix / Troubleshooting
Safety first: Turn off power before handling ozone equipment. Avoid inhaling concentrated ozone.
Steps to check ozonator:
- Inspect tubing: Check the clear ozone tubing from the ozonator to the injector for kinks, cracks, or water intrusion.
- Check check valve: Ensure the ozone check valve is installed in the correct direction and not blocked.
- Observe bubbles: With power on and ozone cycle active, look for fine bubbles at the ozone injection point. Lack of bubbles may indicate a blocked injector.
- Replace ozonator: If the unit is older than 3–5 years or shows no output, replace with a Strong Spas-compatible ozonator.
When to call a technician: If plumbing modifications are needed to replace the injector or check valve, professional service is advisable.
