We drained and refilled our vented CH system today, to replace a faulty motorised valve and to remove and de-sludge one upstairs radiator.
We also added a Fernox system restorer to the F&E tank before refilling.
We refilled the system, bled all the rads, bled the pump and also the vent above the CH cylinder.
Our Ideal Stelrad Turbo 2 condensing boiler will not relight. There is no sign of the pilot light and no noise from the boiler at all, bar a slight 'singing' sound, as if something is expanding inside.
Any suggestions for what to do next gratefully received. Do we need to check the operation of the pump in case of an airlock somewhere?
