Ozone generator is not operating; no ozone bubbles visible at ozone injector

Safety: Turn OFF power at the GFCI breaker before servicing the ozone system.

• Check settings: Some Bullfrog systems allow ozone to be enabled/disabled in the control menu. Ensure ozone is enabled.
• Inspect tubing: Locate the ozone generator and follow the silicone tubing to the injector. Ensure tubing is connected at both ends and not kinked.
• Check check valve: Inspect the ozone check valve for blockage or failure. Replace if it allows water to backflow into the ozone generator.
• Observe operation: During a filtration cycle, look for fine bubbles at the ozone injection point. If none are present and tubing is intact, the ozone generator may have failed and should be replaced with a Bullfrog-compatible unit.
