    Fd fault on Ideal Heat 15

    Yes the valves are open. When we tap the pipe attached to the fernox filter the boiler will light and as soon as you stop tapping it goes out again. It’s had so much done to it now but seems as if it’s something so daft if it’s coming on when you tap the pipe. Any experience of this? The pipe...

    Fd fault on Ideal Heat 15

    Ok, so I’ve taken the magnet out of the fernox filter and when I hold it next to what I believe is the air separator 🤨 it pulls near the top. If the pump is running with the sentinel x800 flushing through what’s the chances of it unblocking the air separator or do they have to be replaced? It’s...

    Fd fault on Ideal Heat 15

    No machine, he put a hose on the bottom of the Fernox filter and x800 in the tank up the loft. But because pump won’t work with the boiler he said gravity would push it through. Water was brownish but then went clear. But now I’m thinking this wouldn’t clear the radiators or would it? Looks like...

    Ah right ok then! So the pump has to be running for it to work? Makes sense to me thinking about it! I just told the second plumber what the first one had done so he will have assumed he had the pump running. Thanks so much, I will get him back and ask him to do a proper flush!! 😠

    Had two heating engineers out and they can’t pinpoint it! BUT, although its had a flush the pump wasn’t running so I think maybe put the x800 in whilst the pump is running on mains. Would you try that first? It’s had a new water flow sensor.

    Weird this is but if I tap on the fernox filter above boiler the boiler light comes on and when I stop tapping it, the light goes off again! 🤔 Its had sentinel x800 flushed through but could it still be a blockage?

    Thanks for your reply, do you mean to wire it to plug top whilst it’s connected to pipes or to remove the head & see if it runs?

    Fd fault on Ideal Heat 15

    Got fd code on Ideal Logic Heat 15. Had two plumbers out and no joy. It’s had a new water flow sensor, flush with sentinel x800 and refurbished grundfos water pump. Boiler tries to light and water pump power light comes on but goes off immediately and boiler flashes fd again. It’s heat only so I...
