Hi all. Hope you can help.

Been to look at an ideal icos he 18 l & f code. Done everything from the flow chart and changed the flame detection probe. Contacted ideal and they're advice was to boil the kettle a few times and flush the heat exchanger to clear the aluminium oxide build up.

Ive also cleared the trap and cleaned out the sump at tue bottom of the heat exchanger. The water i poured in ran out freely with no restrictions.

Im stumped. Could it be a faulty gas valve as it runs fine for 5 or 10 minutes then cuts out. Leave for a minute and reset and it'll come back on.
 
If you were registered, you’d have the blue badge.. but you don’t get the free parking

You rang :D
 
Fave on them is the flame rec lead , they crack and loose continuity, if the probe is brand new , change the lead , I would also , if the customer is ok with it change the spark gen and the ignition electrode , but you could just change the lead and try it .
That normally fixes them . Good luck

The lead from the flame detector? Could it be that simple. Ive tested it with the multimeter and registered voltage when it fired up. Obviously when its running its losing something. Seems strange that after a minute or 2 being shut down it'll start back up again. Ill definitely try it though. Cheers

Very cheap , defo worth trying , but I agree you wouldn’t expect it to break down in a few mins , but honestly I have changed loads .
 
Trying to figure this out.
It would seem that if one is not gas safe registered gas boiler repair
repair advice will not be given on open forum, but once proved to be registered then it is okay to give gas boiler repair advice on open forum.

You have not broken any rules.

Glad you got the answer you need.

An extra 10000 'experts' out there now able to give advice
on fixing icos's.


You are 100% correct it shouldn’t have been on an open forum , I was more interested the OP was gas safe. As for the 10000 new icos experts they now have an idea how to fix one of the many icos fault codes , half the fault codes dont relate to the specific fault anyway , and I have heard theres only 30 left lol .
