Got an airlock in the pipes, take a look for a bleed on the pipework around the diverter valve / cylinder somewhere.

Thanks, this might sound a bit daft but where abouts would that normaly be? I'm a bit of a novice with plumbing, electric is more my thing also I've been Reading that I should bleed the pumps, could this also be something to do with it, thanks for your help

DRain it down again, making sure you open all vents (including any near the cylinder) and make sure that the Zone valves are fixed open! Then re-fill it and see if it helps.
