Hi can someone help resolve issue with burner fire up on my Potterton Housewarmer 55?
The burner seems to start mostly on full gas, the lower flow at startup seems to be failing most of the time.
This means that the boiler igniting is quite noisy, on the odd occasion that the step flow seems to work the boiler fires up reasonably quietly.
The PCB was replaced recently due to the pilot ignition not working at all, at which time the oxypilot and electrode lead were replaced, now the pilot works nicely but the burner startup has not changed. This noisy startup has been present for sometime on the boiler, it's not a great annoyance, however it would be nice to clear that issue as well.
The step flow is controlled by what the gas valve or the PCB? How is the lower gas flow at initial startup done, is it something in the gas valve that is failing to operate or is it a fault on the electrics controlling the valve.
Your help would be greatly appreciated.
Thanks
Phil.
