Does anyone have lot of knowlage on these boilers? potterton promax he i've fixed a few problems on this boiler and the current problem is after aprox 2 hrs the boiler gives off a loud bang and does not ignite for some time after, a few hours. after the bang it tries to ignite but no burner.
I was thinking gas valve when i last went as the valve was sticking a bit and banging when igniting.
