How to Fix / Troubleshooting
Safety: Never look directly at UV light. Unplug before opening any UV compartments.
Steps:
- Clean water system: Even with UV, regular cleaning is required. Follow the deep cleaning procedure for tank and base.
- Check UV indicator: Confirm that the UV function is actually enabled per the manual.
- Inspect UV module (if accessible): Some models allow viewing the UV chamber indirectly. If the UV source never illuminates when enabled, the module may be faulty.
Replacement of UV modules should be done with the correct Beurer part and may require service center assistance.
