ideal icos he12 - h1 status?

[nizzex]

Hi guys

My boiler has started to pack up, sometimes it’s on standby with 0 code and sometimes it goes to H1 code flashing and the boiler does not work, even when turning off and on, may come back standby randomly when it feels like it and can get it work again. I’ve searched to what it could be and it’s not clear to me. Pcb was already replaced some months ago when it does completely and now this? Any input to what it could be?

It’s not something that is repairable to a consumer, please engage in a gas safe engineer, maybe one who specialises in Ideals or at least repairs.

Sure but just would nice to know in case the gas boiler man may not be sure that’s all

Coming up as a control (flow ) thermistor fault.

Ok thanks for the reply I’ll see what the engineer says
