Buderus boiler no flame

Hello Guys,

I have bought my Buderus boiler two years ago. I am satisfied with the performance of the boiler. However, from last few days, I am facing a problem of no flame detection whenever I turn on the boiler. What could be a possible reason behind it? Is something serious?

Waiting for your help


Hi James,

There are different potential reasons behind it but the most expected reason is a choked pilot jet. Well, you cannot diagnose the problem easily. It is advised to call a skilled boiler engineer as the whole process of diagnosing the problem involves the dismantling of your problem in order to clean out a pilot jet & afterward reinstall it.
