icos

I am the proud owner of an Ideal Icos HE15 that is 17 years old and somehow still functioning. I know that this boiler cannot modulate down very well, but I have got it working reasonably well and have spent a decent amount of time getting the pump speed sorted & balancing the heating system...

Hi I am wondering if anyone came across the following issue with ICOS boiler. Suddenly, it has started making loud noises - first every half an hour, then every 10 minutes and then it stopped working altogether with an FL or LF failure code on the display. If I reset it, it makes the noise...
