Well at least you got five years out of it! I gave up on Drayton and fitted a Honeywell valve instead a few months ago (see other thread). So far so good. 
By the way a trade outlet sort of admitted that they 'have had bad batches' of these actuators. Seems to me the problem has surfaced only since Drayton decided to make the unit in two parts to make actuator replacement easier. It was a good idea but the initial tolerances (slack) seem to increase and then the 'clicking' issue starts.

It was a long while ago when they made the heads replaceable.
I have to say that they are about the worst type of actuator.
Very fiddly and plastic bits break inside after a few years when they get brittle.
Very difficult to replace the motor and I would never do that as its not worth the trouble so would just replace the whole head.
