Radiators not Heating Up

This is what the boiler displays after I turned on the timer:

The first shows a system pressure of '2.2 bar'. That's a bit too high. Not a major issue on its own, provided everything else is hunky dory, but a tad too high. We'll look to reduce that down to, say, 1.5 bar shortly (by bleeding a radiator), but for now we need to try and sort the other issues.

You don't need to unplug the boiler, just turn it off at the bottom-right switch near the analogue pressure gauge. Wait 20 seconds (in case it makes a difference...), and turn it back on. What does the display say?

If it's 'normal', then try turning on the CH again.

If it goes awry again, then turn off the heating demand, and press the top-left of these four buttons on the panel - that's 'reset'. That should 'clear' the fault, but it'll obviously return if it's still there.

Have you moved in yet? Really worth having a service carried out as soon as you can.

On a different note, how do the two indicated pressures compare - the digital reading and the analogue one?

F.32 fault - interesting. Looks like it's common enough, but not necessarily major - ie the fan itself might be ok. Jump to 1 minute in:

If this is an unoccupied house, there could be damp in there, for example. Obviously not for you to sort

Definitely try a reset.. When I moved in we also had a boiler with pressure over 2 and we would get a random fault code. A reset would clear it and when the pressure was reduced it never came back.

Sorry, uploaded the wrong photo in my last comment. It should be this one below. I can see both sides are pointing to OFF.

I am going to turn it on by following the instructions.

That is a dual-channel programmer, but you seemingly have a combi boiler? I'm soooo confused :-(

You also have a 'power shower' switch, and that would only be available on a stored hot water cylinder system. Do you have a how water cylinder in there?!

Anyhoo, we'll park that for the moment! Well done - that looks like the baby; and only turn on the 'Heating' (RH) side for now - click it to 'ON' until you work out how to set the timings, and then you can change that to 'TIMED'.

 

Yes, the timer is just besides the hot water tank. I think it’s a gas fired boiler, not a combo one.

I haven’t tried that shower setting yet.

I turned the boiler off and back on. The display is normal. Then I turned on the timer. Looks like the boiler is back to working this time, at least I don’t see that F32 anymore after the boiler running for at least half an hour. The radiators are also now hot.

We haven’t moved in yet. Yeah, I agree that the boiler and heating system require some checking before we move in. It is an old boiler and the last service happened in June 2021.

I’ll check the pressure again when I back to the house.  Now I am out to looking for some bathroom stuff. I’ll also check if that F32 code came back or not.

That boiler is a system boiler based on the product code rather than a combi

Good, at least we know it is not a combi and can give sensible suggestions,  although it looks to be sorted since discovering the programmer.

It's not an old boiler btw. 12 years is nothing especially for a good make like valiant. 
Give it a service and you might find it goes on for another 10 years with no problems.

Good news, hopefully it will keep working now, and it shows the system does work at least, so if there is something needs fixing it shouldnt be major

I think radiators and boiler are now working! Thank you all for the helps!

Now I notice the pressure is even higher. It is 2.8 when heating.

Can I just leave it like that? I do plan to ask a gas safe engineer to service the boiler, so I guess they will fix that?
