Troubleshooting a Flue Thermistor Fault

When your Baxi boiler displays a flue thermistor fault, it typically means there is an issue with the temperature sensor in the flue. This can lead to erratic heating, hot water fluctuations, or even a complete shutdown of the system. To troubleshoot this issue, start by checking the connections to the thermistor and ensuring they are secure. If the connections are good, you may need to replace the thermistor itself. Consult your boiler manual or contact a professional for guidance on how to do this safely and effectively.

Another common cause of a flue thermistor fault is a build-up of dirt or debris in the flue pipe. Regular maintenance, such as cleaning the flue pipe and checking for any obstructions, can help prevent this issue from occurring. Additionally, ensuring proper ventilation around the boiler can help maintain the correct temperature in the flue, reducing the likelihood of a thermistor fault. By addressing these potential causes, you can help keep your Baxi boiler running smoothly and efficiently.

By taking proactive steps to maintain your boiler, you can extend its lifespan and reduce the likelihood of costly repairs in the future.
