Vokera Flowmatic Boiler fault code A11

Hi Guys,

I have bought the Vokera Flowmatic boiler seven years ago. Last night, I got extremely frustrated when I turn it on. The boiler is showing an error code A11. I have restarted it many times but still it is showing the same error code. I do not have any information about it that is why I am here to get some valuable suggestions.



Hi Ben,

An error code A11 deals with false flame. When this happens, the boiler constantly senses the flame when there is no need for a burner to operate. Well, the common reason behind this fault code is a sticking gas valve. As you said that, your boiler is seven years old & this problem is quite common in old boilers. I would advise calling a boiler repair expert in order to replace the gas valve.
