The repair kits are available to re-build your divertor valve but it is generally not worth it on this model.
It involves the removal of the plate heat exchanger, the integral filling loop, the by-pass pipe and one part of the heating manifold.
Almost every joint in this process involves the replacement of "o" ring seals. They come with the new valve and include pretty much everything you need. As a caution,though, it's not a thing for the feint hearted to attempt at d.i.y. level.
