Icos he18 l and f code

[Christopher Powell]

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.

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 .

Doubt there 10k left in the uk

In reality, the short time this post was in the public forum, probably went unnoticed by the majority.

Changed the leads to detection probe. Checked all measurements from the top of the chamber to the probes still cutting out. Any other ideas

 

[Christopher Powell]

Could it be overheating, as first time rynning it stayed in for 10-15 mins but then less after each restart

 

[townfanjon]

Bugger !! Get ready potential nightmare now.
When it cuts out , does it cut out “dead” no fan etc , or do you get the flashing blue light , then goes to fault

 

[Christopher Powell]

Tries 3 or 4 times then cuts to fault ive been onto ideal and checked the resistance across the gas valve and they think the solenoid is overheating and slamming shut

 

[townfanjon]

I would think thats more than possible pal , could be worth a shot , or more to the point it may have to be.
Where are you based ?

 

[Christopher Powell]

Bridgend area South Wales .

There's not really alot in there to go wrong really is there. Hope a new valve sorts it.

Ideal helpline happily dishing out info without checking i was gas safe too

Reason I asked is I have a working / secondhand valve , you could have cadged it if you were closer.
Let us know how you get on .
A lot of the wiring on the Icos harness / loom is starting to split and break but to be fair , they are old boilers now .

 

[Christopher Powell]

That would have been handy lol. Thanks for the help. Much appreciated

Doesn’t the 3 lines appear on overheat?

Not sure pal , think the overheat codes are L E / L F .i have heard of the 3 lines , but never seen them .
Probably means “ The End “

 

[Christopher Powell]

L A is overheat according to MI's

Hi guys. Thanks for all the help. Little update. Changed the gas valve over. Problem solved. They say trust your first(ish) instinct dont they.
