yes most likely the diverter is faulty. u will need to drain the system and turn the electrics of on the heating. then its simply unscrew the old valve and fix in the new valve. to make it easier try and buy the same valve as your replacing or one from the same manufacturer. also when u change the valve u will need to wire it to electrics again. when u do this take 1 wire off at a time and connect the exact colour back to the same connection.
