Ideal Icos HE12 constant F L Code

[Datsun770]

Folks

Me again

I am at my wits end. I want to replace the boiler but I am on my backside and cannot afford to.

I have been getting an intermittent F L Code. For around a year. I've had an engineer out 4 times.

In that time boiler has had a new PCB, new electrodes, new gaskets, new (earthing wire) whatever the fail safe wire is that tells the PCB the boiler has ignited.

After that was done it was serviced. Worked fine for maybe 2 months. No issue.

I got a smart metre installed last week probably nothing to do with it but thought I'd mention. New gas and electric metre.

It powers up, ignites, then cuts out and cycles like that until the Code.

Sometimes it'll.start working on a reset bit today it's just refusing to go on, meaning no hot water.

I'll need to get an engineer out again but anything obvious I could check that's rudimental I'd be glad of the tip.

Thanks

Check the emergency control valve is fully open (at the gas meter), failing that could be debris in the gas pipe following the smart meter exchange.
