Bleeding the radiator - hissing air, but no water?

[helpneeded222]

Hi,

So one of my radiators doesn't get hot at the top. I tried bleeding it, but after the hissing stops, there is no water.

Could anyone tell me why this is? And what do I need to do to rectify this problem?

Thank you

What boiler do you have

Have you topped the pressure up on boiler to 1bar

I don't know a lot about it. But on it it says: Worcester 24CDI - if that means anything to you?

yeah pressurised system, you need to have a special worcester key to top up the pressure on that boiler

But if that was the case. How comes it doesn't affect the rest of the radiators?

Is your heating still working after the hissing stops or do you have to top up the water pressure ?

Yes. You should have a silver braided hose under your boiler. And on the display you will have a guage that displays the pressure in system

Once you have found them 2 items. This video will show you the rest http://www.youtube.com/watch?v=23vahQHOnGo&feature=youtube_gdata_player

Heating still working. Just goes back to how it was

simon, its probably wont have a braided hose as its an integral fill loop on this boiler and theres a key that slots into it while you unscrew a grey knob, the others all work as they are obviously full, the boiler will operate alot better if kept up to correct pressure.
