There is no kit available, a new valve is the only option.
It can be replaced without removing the pump, when taking it out just remove the screw (bottom left of the pump) that holds it to its retaining bracket allowing it to swing forward for removal replacement of the diverter.
Just as a footnote, to save lots of water going everywhere when removing the diverter (even after draining both sides) use P6 to put the diverter into mid-position for better draining before removal.
