Just about to start changing the pump and was looking around inside the boiler. Should the pin in the picture go flat ? , that's as far down as it goes

its came off the microswitch so should be ok if it was fully up still making the microswitch after demand it would stop the boiler from firing next time there is a demand

I changed that diaphragm last year. The old one was ok but thought I would swap it as was doing the dhw diaphragm at the same time.

when it does stick up and making microswitch .
there is a hole under the diaphragm that gets slightly blocked and needs poked out

Cleaning the filter seems to have done the job . Thanks for your help .

Only issue now is my new pump ( brand new old style from eBay) makes a buzzing sound, like the old fashioned fluorescent tubes made . Hopefully it's with it being the energy efficient one ,my old pump wasn't

I fitted a new, energy efficient pump, to replace my ancient failed one last year. Mine is completely silent.

This is the one I put in it's a new old style pump. Definitely not silent

My old, failed one was similar. The replacement I bought, cost around £120, from SF, and it's quiet as a mouse. It has a display, showing what wattage it is running at, and usually shows 11watts.

I looked at them but didn't fancy changing the pump body . The head was the extent of my abilities
