Thanks misterdubya

Hi Thanks for the advice. Can you elaborate slightly please as i don't feel i could ask that question to the engineer in a meaningful way. Do you mean, get the RGI to check if the gas value is closing properly when the boiler is switched off?

Update: My engineer visited last night to diagnose the issue. Although it is not possible to see the 'spark' or pilot light in the 'viewing window' it turns out the PCB is actually sending a spark and lighting the pilot light. The issue is that the PCB is not receiving the signal to...

Presumably these pcb's have built in safe guards to stop other sources breaking them e.g. fuses....?

Thanks for the feedback. I have checked the lead and all seems well. Do you know what the other faulty parts could be to cause the current issue? The original fault has come back on the new part that is only 3 months old. Thanks in advance

As it turns out the supplier will not honour the warranty. They said that the PCB is a central unit that takes feeds from many sources. Any of those sources could have caused the PCB to fail therefore it's not the PCB's fault! I would have thought that is the PCB is prone to failure from...

Hi. Yes i will be replacing the part under warranty. Doesn't it sound a little odd that the original PCB lasted about 13 years and the brand new one only lasted 3 months? Exact same issue on both. I'm trying to find out if there is a 'bigger' issue that is causing the pcb to fail...

Any ideas's anyone? thanks

Hi Yes the fan is running. The whole initiation process seems ok but it just keeps 'ticking' and flashing on the pcb and never lights because there is no spark at the boiler burner. There are 4 led's that come on, 1&2 together then the 3rd when it starts the igintion attempt and gets stuck...

Hi, thanks for getting back to me. Yes I am sure the part is under warranty as it is only 3 months old. It was brand new and not a reconditioned part. Im just curious how the same fault can be recreated within just 3 months and im starting the think there is another unidentified issue that...

All I'm after some advice and hoping someone can help me. I have glow worm space saver ksb 30 that is about 13 years old. About 3 months ago it stopped working. The issue was that the boiler would not light. The fault was that although there was a discharge light on the pcb a current...
