Again - Haven't done much on Ariston's - not many people install them or would buy them as they haven't got a great reputation.
If you have to remove the diverter to change the diaphragm, then you will need to isolate the electric and cold water supply, open hot taps and drain the heating section of the boiler, if you can access the diaphragm without removing the diverter from the boiler then you may just have to isolate the electric and cold water and open the hot taps.
Protecting yourself from electrics (electric shocks) and protecting electrical components from water (for damage and ££££££) are the main concerns, place a black bag and over the PCB, any water that escapes should run across the bag and onto the floor.
If you're unsure what to do - get someone in to do it for you - an RGI.
