Have not worked on these bad boys or isars for a good while, bit of a heads up please...

flame failure code, usual checks ? Pressure at valve ? Check condense, leads, electrode an spark generator ???

oh by the way, took loads of isars recently...

anyone want any used boards let us know 🙂
 
Re: Ideal icos LF fault

Pour thermite on appliance.
ignite thermite.

Label as ID and tell them they need a new boiler

Well considering the young girl has no heat or hot water apparently, am hoping I can try an fix it for her as I have nil chance of fitting a new boiler for a while, which is no good for her an secondly a waste of time for me

ID and new boiler?
I know its a ISAR but might be a quick easy fix!
This post needs to be in the GSR forum so people can put in detail what to check, one item that can cause this would only need a clean

Tell her i'll warm her up 🙂
 
only reason i said l9 as i was out at one today and the thermister had over heated due to a dead pump
 
right headings correct then,when you guys post stuff the wrong forum and us mods move it for you we lose all visibility of what you have posted,so try our best to put right,better idea would be to double check yourselves before posting saving us the hassle
 
It's not pcb, first check electrodes, then the rectification harness. If when this is done u get the 3 lines of death it's the pump as well.
 
Popped out, she qualifys for new boiler on Eco so it's not getting fixed.

fired up an cut out pretty straight away, inlet pressure ok, removed panel at bottom of burner that was clear ??

surveyor going out tomorrow to book her a freebie in

She'll probably be waiting until April, when the new funding kicks in.
 
Oh ok.

Going back to the Ideal, I had an icos Thursday where the condense was blocked under the sink where it teed in to the waste. That was causing it to lf. It was also leaking though and being noisy. But I've had this numerous times with new builds.
 
Thought this was the Gas safe forum?? It's usually the electrodes but also can be the condensate trap
 
There is a replacement harness and earth bond on rectification as it's been problematic !
