i changed a tap washer in a down stairs cloakroom sink and after turning the hot water back on no water came from this tap. All the hot taps in the rest of the house are fine.The system is gravity fed.

What happens when you unscrew the top of the tap?

Thankyou for your reply, but since posting this question i have found that the cause is an airlock in the pipework.
Sounds like you have an old system which was installed a while back when air locks were not considered. Its a bit crude but i have cleared the same problem by linking the cold (assuming it mains) to the hot spout with a hose and blastsing/back filling for just a few seconds with mains water. This will often clear the air lock and makes light work of fixing the problem. You can do this on the heating system as well but its a bit more tricky and i wpouldnt recommend it
