Villeroy & Boch Ozone System Not Operating

Ozone bubbles not visible at ozone injection point

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed Villeroy & Boch ozone generator, Blocked ozone check valve, Kinked ozone tubing, Ozone output disabled in control settings

Safety: Turn off power before handling ozone equipment.

Check settings: Verify in the Villeroy & Boch control menu that ozone is enabled (if user-configurable).
Inspect tubing: Follow the ozone tubing from the generator to the injector and ensure there are no kinks or breaks.
Check valve: Replace the ozone check valve if it is blocked or allows water to backflow into the generator.

If there is still no ozone output, the ozone generator module may need replacement.
