Ideal Boiler No Hot Water

[davecpfc]

Hi

Hope this is in the right place, looking for some advise.

I have an Ideal Icos HE24 boiler and today it has stopped heating water. It has power running to it, both the time display and boiler.
The source code is 0 but the light for the burner doesn't come on and holding reset doesn't do anything.
I have turned the whole boiler off and turned back on, when I do this it flashes 4 once and then goes to 0 on the source and has no bar of pressure showing.

Is there anything I am able to do?

If you need any further details please let me know and thanks

Can you take a photo on the right hand side of the hot water tank cant make out what is in that corner, I can see a gauge on the pipe work , what is that reading ? the chrome flexi that you are showing is the expansion from the tank , is the one on the right hand side the same sort of pipe ??

I might be missing something but 0 on an Icos is no demand at boiler. C sw live received foe boiler. Could be controls

Hope they help..
Turns out the heating filling loop was closed, opened that and the tank has now filled but still doesn't seem to be kicking out heat or hot water. Once I open the heating loop the pressure bar went from 0 to just over 3

turn the filling loop off and its too full needs to be around 1-1.2 bar to get the pressure down bleed a rad

Yes that is correct 0 is no demand but even without tap running nothing changes and heating not kicked in even though on at control

Take it all controls are calling for heat ? Room stat turned up, on at timer etc.,

Yes all turned on

Yes all turned on

Have you pressed the reset button ???

Bled rad to around 1.1 and filling loop off

Yes nothing happening

Time to get a gas safe engineer in then I'm afraid

0 is boiler has no demand. Icos is a heat only boiler not a combi. If display does not change to c then boiler is not getting a demand. Faulty external controls. Get someone in to check. A better picture would help

Not a sunvic programmer is it ?

That silver vessel on the cylinder looks like its full of water & hanging onto the wall for dear life!

It's a Honeywell programmer
Gassafe the vessel isn't full, had this one installed on Thursday as old one was faulty and full of water. I am going to be replacing the wood it is attached to tomorrow when I can get some from work
