Combi Boiler / possible air lock

[2oakcourt]

I have a combi bolier, and up until now I've had no problems with CH / Hot water.

Recently I attempted to remove a radiator from a wall whilst decorating. I aborted this attempt when the water flow seemed too much (loosened the lockshield valve end).

Since then no radiators warm up at all and there is no hot water. I have heard some banging when turning taps off quickly. Also, the pressure in the combi bolier reads 0 on the meter!!

What should I do?

Thanks!

FIllit back up with water. Do a search on Filling Loop.

Call a heating engineer. It'll be the quickest 60 quid you've ever spent!
