Heated towel rail issue

[ETTelephone]

I have an open vented system with a conventional boiler. Moved in recently and two heated towel rails came on with both heating and hot water. After a couple of weeks one towel rail has stopped coming on with the hot water. It still works fine when the heating is on! Any ideas?

Cheers

Someone altered a rad valve ?

Nothing altered anywhere in the system to my knowledge. Valves on affected towel rail are open.

Have you bled the towel rail - and check the f+e cistern water

Towel rails and other rads all bled. Will check the F+E tank, thanks!
