Thank you! Are there any risks to changing this myself? I obviously will isolate to the boiler before, when i open the part to replace the diaphragm will i be greeted by water?!

My boiler isnt giving out any hot water I can see that the the little plunger that closes the microswitch isnt moving so i can assume that the diaphragm needs replacing? The problem i have is if i close the microswitch myself which then turns the hot water light on the display and flames...
