Hi, my radiator in the bathroom has gone cold all of a sudden and having read lots of posts about similar situations on the forums here I would like to try to remove the TRV head to tap the pin. It is an Ecocal TRV and I have no idea how to remove it! Any help would be gratefully received.

After much fiddling around with the TRV I've worked out how to take it off, but the pin wasn't stuck down. So now I'm not sure what to try next. It's just the bathroom radiator that is totally cold and the pipe leading to it is cold too. I've bled it and the water coming out is clear. Any suggestions what I should try next?
Turn all other rads off and run the heating to see if its an air lock.

I ran the CH for about an hour with just the bathroom one turned on, but it didn't heat up. In fact the pipes coming out of the boiler (Worcester Combi) don't even feel particularly warm.
