Ozone or UV sanitizer indicator is off and water quality declines faster than usual.

Safety first: Turn off power before servicing ozone or UV components.

• Check indicator: Verify whether the Aquavia control panel shows an ozone/UV status icon or error. Some systems only run ozone during filtration cycles.
• Inspect module: Locate the ozone generator or UV unit in the equipment bay. Ensure its power connector is firmly seated.
• Replace UV lamp: If equipped with UV, replace the lamp according to the maintenance schedule (often annually) and reset any lamp life counters in the control menu.
• Replace ozone unit: If no ozone output is detected (no bubbles in ozone injector line during operation) and power is present, replace the ozone generator with an Aquavia-compatible unit.
