My Potterton Suprima 60 sometimes goes to a flashing green light.. you can hear it sometimes trying to do something but not coming on and the radiators don't get up to full temperature even though the thermostat on the wall and the radiator thermostats are up to the max....anyone know what the flashing green light means??
