So it needs a new diaphragm?

Thanks Tom,

Part ordered and will be giving it a go this weekend.

It is a case of removing the screws on the diaphram housing and replacing the new one in the same order

Diaphragm Kit to fit specific Giannoni diverter valves
To fit, simply undo the 4 screws on the valve and replace with the new diaphragm and spindle.

Do turn off the mains water supply first.
Also place a bowl beneath to catch the water that comes out. Switch off electric supply to boiler.
Ive replaced mine different make but simple enough --hope this helps --just take your time.
