How to fix a constantly red light on my Buderus Boiler?
- HHannah GutierrezAug 18, 2025
If your Buderus Boiler is constantly red, and you're commissioning or restoring factory settings, it could be because neither BUS nor LAN connection is available. To resolve this, disconnect the module from the power supply, make both BUS and LAN connections, and then recommission the module. If this occurs otherwise, it indicates an internal fault, and you should replace the module.
