The old diapragm was in pieces so the pin would not extend when the Hot top was turned on. I have fitted a new diapragm and brass cover, however now the pin extends but does not retract fully, leaving the switch on all the time. I have checked that the diapragm is seated properly and replaced a worn o ring on the water regulater behind it but it still does not retract properly. Any ideas? I need to keep the old boiler running for 6 months or so until a brand new boiler is fitted in a new extennsion.

Yes, spring fitted and correct way round- I will try some grease though. When removed the pin moves freely against the spring, but when installed it might need lubricating, so thanks for that.
If everything else is correct then the only cause would be a blocked entry to either side of the diaphragm.
That can be checked by VERY slowly turning on the water supply and making sure water comes out of BOTH entry points.
Thats very unlikely though.

Thanks Tony, I'll try to see if one of the routes is blocked. There is a regulator behind the diapraghm, Ive replaced the O ring but I wonder if this is failing also, problem is the part S801187 does not seem to be available.
