right i have replaced it but now the boiler isn't firing up for hot water. The boiler is working for the heating just not the hot water. You can hear it click but thats it.
i refit the old one. the switch seems to be ok.

I can get hot water while the heating is turned on and i can see the boiler flame get brighter when both water and heating is on it won't fire up with the hot water on its own.....
When i press the switch manually i can here it trying to fire up but it doesn't ignite.
Now just to muck me around even more it won't ignite for the central heating. I can hear it sparking up though.
Does anyone have any ideas????
I know im being a pain but i really need some help about now 
. I Have watched things carefully and the new diaphram pops out but doesn't seem to touch the switch, the switch works manually and you can hear the igniter sparking but no flame. Eailer the Central heating would fire up and you could get hot water that way but thats not working now but you can hear the igniter working.
Could some please give me some advice on what to check.

The moving pin sounds as if you have reversed the diaphragm. Two springs should both be on the switch side.
I have no idea what you have done to stop the boiler firing up!
Did you take the connections of the microswitch?
Were you naughty and opened the combustion chamber or touched anything else that you should not have done?

Sorry but i should of replyed!. It looks like the previous owner had been messing as i found the problem. The ignition cable running up from the switch had been cut at one point and had been resoldered badly and had come loose. I found it after taking the metal cover from the top chamber off so i re connected the cables and it works fine now.
opps yes i did place it in the wrong way round.
