Ideal Classic FF240 Boiler - Cutting Out

[jarvo]

jarvo....So the boiler fires up and runs for up to 15 mins, then cuts out and the pcb is then arcing ??

Hi,

The only thing that is arcing is the little black thing in the image below, marked SG1.
This arcs when it's trying to fire up.

The fan does make a bit of a noise, so could easily be on the way out.

Have BG coming tomorrow morning.

Had company around this morning HUG limited to quote for a new boiler.... No price yet.

Think of it needs replacing I will just pay BG to do it as no bugger in Yorkshire seems capable!

But it's noisy

And it will be as it's overheating. I've been to loads and I mean loads and never once been the hex.
99/100 it's the pump. Then looking at circulation.
Has anyone suggested temp diffs on flow and return?
First thing I do when I go to one.
But then I'm only an Ideal engineer, what would I know.
Suggestion of F/E, blocked cold feed or partially choked flow or return or airlock after draining and bleeding rads as OP had stated.

Oh well

Bet it needs a power flush.

I asked him to test how far the heat is getting. Not differential as I doubt he has the equipment,
I'd like to know how far the heat is getting to see if there's any circulation.

Bg won't necessarily just say powerflush/new boiler.
They do have some good engineers that will diagnose and repair.
If it is a blockage. They should find it sort and quote for a powerflush

Op said he had the pump replaced fairly recently, and if he's just drained and refilled the system it all but rules out a blocked cold feed.

Doubt it is this, but just too rule it out anyway, make sure both gate valves are fully opened either side of the pump.

I'm on about blockage

probably an H pattern vent and feed.

I cant be arsed to read the whole thread but from the OP it isnt the boiler thats the issue.

edit
forget what i said

i agree whith the others, its circulation problem.

who fitted the pump. it is the fitted the right way round? what speed is it on? it looks like a wilo but unsure. don't they normally have a setting to purge air in the case of an airlock?

don't they normally have a setting to purge air

They do. You put the speed selector at 12 o'clock (assuming vertical orientation).

The picture of the pump looks to me like the pump
Is maybe in the bleed setting?
But I am looking in a phone and the qualitys not great (picture not my phone)

 

[Dan Robinson]

I've not looked at the picture. I'm using my ninja skills

 

[dang32]

does that mean that it wouldn't run properly?
i don't use wilo pumps generally so unsure of settings
