Ozone indicator is off and water quality declines faster than normal; no bubbles from ozone injector (if visible).

Safety first: Turn off power before handling ozone equipment.

• Inspect ozone unit: Locate the FreshWater ozone generator and check for power indicator lights (if equipped).
• Check tubing and check valve: Ensure ozone tubing is connected and not kinked. Replace any brittle tubing and the ozone check valve if clogged.
• Replace aged generator: Ozone units typically lose effectiveness after several years and should be replaced with a compatible Hot Spring ozone system.
