I recently decorated and removed two rads, the DHW was still working fine, but there was a red flashing light below the image of a half filled rad.
I refitted the Rads and re-pressurized the system, bled all the rads in the house re-presurizing as required, ending with the pressure at 1.5 bar. The heating runs ( flow & return at boiler getting hot) and all rads get hot. Sounds like a good result! But light still merrily blinking away? Any Ideas?
