Hi,
I've just had a bit of a refurb and all the rads were removed. Hot water worked throughout this process, however once the rads were put back on I tried the heating, only to find the rads weren't bled (note I didn'te remove and replace the radiators!).
I bled all rads, and then reset the pressure to about 1 bar, however the boiler will no longer fire. It makes a churning sound for a few seconds, maybe repeats a cycle of the same sounds, and then the LED flashes 4* a sec.
Reading the manual, it sounds as though there may be a component problem (ignition PCB perhaps), however I would have sworn it more likely there is air in the system. I've checked the auto-air vent and it is lose, so I would have thought the boiler would bleed itself, is there anything else I'm missing?
Many thanks,
Kevin
