Just to close this one out, I decided to try and change the valve as a last resort. It turns out it was that that was restricting flow, even though the motor and spindle were operating fine - the innards (diaphragm?) must have been buggered!
So the e majority of you were right all along! Moral of the story: just because all appears well, doesn't mean it is!
Thanks again.
