I have an on-going issue with our boiler which is presenting as follows:
• Tries to fire, burner briefly starts
• Burner goes out after 1 second
• Cycle continues until the boiler locks out
• If you leave it a day to two and reset it, it might fire up again, it was regularly locking but would start immediately when resetting but that has stopped now
My plumber came out due to a leak from the heat exchanger manifold and managed to successfully change it and stop the leak. Whilst he was here he did the following to try and sort my issue:
• Cleaned the condensing container (was full of soot)
• Checked and cleaned the burner
• Checked the burner seat/seal to make sure it was secure
• Replaced the cover seal
• Checked the flue seal
• Checked the efficiency of the burn and carbon monoxide
• Checked the main gas feed and regulator and we're getting between 24-18.5
• Checked the ignition (although this was replaced 12 months ago)
Not sure where to go next, the plumber said he could change the gas valve, that would perhaps be the first thing he would check, but before I do this I wondered if someone could look at the videos I took and maybe shed some light on anything else that should be checked. I know the PCB can be funny on these things...
