Diverter valve reqd but you would probably be better off spending money on new vaillant or worcester
 
divertor valve spindle is moving backwards and forwards when switching between heating and hot water :?:
 
But the seals are being held open by debis or are crusted up and hard or the springs are weak.

I'd go with a new DV as well, but get someone in who is used to working on Ravenheats.
