Paul Barker said:Before removing anything operate the hot tap while at the boiler, if no tap where the boiler is turn on a hot tap and operate it on off on off via the cold feed isolation valve. Listen to what is happening, in all cases if the diaphragm is in good order you will hear a little click as the prong dips down, operate the boiler many times to prove that this hapens consistently every time. If it does you have proved that the diaphragm is not the fault. Next, ask yourself does the boiler fire each time? If you ever, even once hear the click but the boiler does not begin the next phase (which is start the pump and the fan) you have a faulty microswitch. But as I said renew it anyway.
No just lift it off, only needs strongish fingers.Its the black circular piece with the white plastic push rod thats difficult, and I'd need help removing that.
