How do I stop a Gainsborough 8.5 ES from dripping?

I have a Gainsborough ES 8.5 Kilowatt shower which after 2 years has started a constant drip, day and night. I suspect the Hartlepool water (which is filtered - fat lot of use) and its high lime content clogging up something - but what?
I am loathe to jump in and start taking things apart without a little guidance as to where the gunged up article is situated.
Any help would be appreciated.

Obviously I can't then.
