Ideal Logic F1 Fault: How To Repair Your Combi Boiler

Allen HartBoilers, Central Heating

Ideal logic low water pressure

Today, I’m just at an Ideal Logic with low water pressure. So if you get an F1 fault on an Ideal Logic, I’m just going to show you how to top it up, how to fill it up, or how to re-pressurize it.

The F1 Fault Code

If we have a look at the front there, it’s showing F1 as a boiler fault. Now I’ve taken the case off from this boiler, just because it makes it easier for me to show you the pressure gauge. The pressure gauge is there, so if you see on there, it’s on zero, all the way down there at zero, and it wants to be up that black line there.

What you’ve got bear in mind is, when you fill this up, is not to put too much pressure in. You see all these valves, this one, there’s the yellow one for gas, and then these ones at the back here, don’t touch them, leave them alone. So these here are the only ones that you need to touch, so I’m going to explain what happens. Your system is sealed, and every now and again they’ll need topping up and more water putting in.

What we’ve got here, this pipe here is the cold water mains, so that’s your cold pipe coming in. Then when you open this pipe here, this one, it’ll allow water into there and round this flexible pipe here, and to there. Now that’s still turned off. And as we open this here, as I turn this now in a minute, this pressure gauge will start to go up, and then that F1 fault will go off.

But as I say, you need to be very careful, and do this slowly, because you don’t want to put too much pressure in. I’m going to do it slowly, and I don’t know if you can hear that, but water’s now going into the system. And as were doing that, that pressure gauge there is going up. So I’ve only opened it a little bit, just for a demonstration on this video.

It’s saying FL, or F1 sorry, and the gauge is going up, so I’m just going to open this a bit more, and then the boiler’s actually fired up. So that means the fault code’s gone off, because the boiler’s fired up. So I’m going to just switch the boiler off now, just so we can do it without the power on.

We’re just above now, where we’re going to be, this will drop down a little bit as we use it. So turn that off fully, and then turn this one off fully. So that is how you filled up your heating, and there you go. So when I turn the power back on again, you see your fault codes have gone off, and then the boiler will just work now, as normal.

I’m just going to do a service on this. So that’s how you top up, fill up, and re-pressurize your Ideal Logic Combi boiler. Hope that was useful, thanks for watching.
