any boiler experts? keep cutting off and need to press red button to get it going again

  1. It sounds like an airlock? Did your tank run empty and then you filled it?

    If it is an airlock there should be a stopper on the left hand side you will need to remove with a spanner. Press the red button while the stopper is removed and when the fuel is coming out in a steady stream put the stopper back in. You should wear gloves and put a container under the plug to collect the fuel that spills out. Its messy enough but easy to do. Look up a YouTube video if you need.

  2. If it’s air locked and needs bleeding it’s not going to start up even with the red button.

    It’s a 20 year old kerosene boiler, and I think maybe it’s at the end of its life.

  3. Airlock! You’ll have to bleed it a little. There should be a little valve that sticks out to the bottom left and you loosen with an allen key, keep pressing the red button till the kero comes through. If its bubbling, there is still air. It should be free flowing.

  4. Presuming you haven’t run out of oil recently it could be a few different things tbh …..a service person should be able to get that running sweetly for under €100 and it will nearly pay for itself with efficient running…

    Source…I’m a plumber

  5. Might need bled. Especially if it hasn’t been on in a while, was running low or had a refill. But that’s the most obvious answer. I’ve done that before and it worked, done that before and it hasn’t worked either. Oil boilers are a cunt.

  6. Usually means the burner starting sequence is faulting out for some reason. Could be a few things.
    – not enough fuel flow or pressure. Did your tank level get very low? Did you refill recently?
    – faulty sensor, if it hasn’t been serviced in a while it might need a replacement or a clean.
    – not enough air flow. Motor failing or blocked air inlet.
    – water damage. Did any rain get in at this week?

    Best to get an expert out.

  7. If it has a self bleed clear mushroom beside it press power button on and then red button twice 30 seconds apart

  8. If its not airlock it could be grit stuck in it from bottom of tank, its easy enough to free it, youtube it, my dads a plumber he talked me through it on fone

  9. So I called plumber and he said water was low in it and now its off again hence why I’m trying to do it myself

  10. This looks very similar to Oil boiler I had . Last time I had to reset by pressing button to get it started , it was the Pump it’s faulty it needs replaced unfortunately, if you find you have to do this all the time that’s what it is . Now this was about 10 years ago my Ex’s Uncle repaired these and very trustworthy he only charged us £80 for new pump. This is one required for your Boiler !

  11. You can make a siphon for sucking the oil without getting it in your mouth, a bottle with two rubber pipes, like a bug collector you’d make in school

  12. You’re just showing off… look at me I can afford to turn the heating on.
    Anyway, get a spanner underneath where the fuel come in, loosten it a bit and let the air bleed out… most likely just an air bubble in the fuel line, highly likely if you let it run dry and have just filled up.

  13. Airlock or check that the pin hasn’t dropped on the fire valve.

    Have you had is serviced recently? If not it could be that the nozzle is blocked and needs replacing which is done at a service.

  14. Expert here.
    Could be a few things.
    Airlocked fuel line…..if you recently ran out of oil and got a refil, there could be air in the line. Bleed viia allen key bolt on side housing.
    Air flow. Unless you changed it….nope.
    Flame sensor…..it is clean.

    Capacitor……If it lights up for first cycle then fails to restart prob need a new capacitor.

    Solenoid ….Could be. Have to test it.

    Clean the ignitors, spark electrodes.

    Corrupted nozzle??….get a new nozzle . Make sure its same size..

    After that……a new control box?

    New nozzle wou

  15. That takes five mins to sort, lossen the bolt on the left(don’t take it all the way out, just a few turns), press the big red button and when you see oil squirting out tighten it up, might need to repeat 2-3 times but I have had to do it a few times to mine when I let it run dry
