I recently traced a fault on my boiler to the automatic bleed valve on the pump not working, can anyone advise me howto go about removing and fixing it? is it even possible to fix them or do I have to replace it? Any advice at all will be appreciated.
How do I fix a baxi 80e automatic bleed valve?

yes its open, i even took the screw out completely but it won't bleed. there is corrosion built up around the hole and i assume there is more inside which is why I want to take it out and clean it up. I was able to bleed enough of the air out to get it working by briefly slacking off the allen key screw on the front of the valve until the air came out then tightening it back up but there is still air in there so I want to get it working properly so I can get rid of the rest.

unscrew the top and re-new. Piece of pis s.
Or bleed the air out through the pump.

It's most likely the float inside the valve is stuck....
Maybe worth a go to take it out and try cleaning, but in my view it's prob best to replace it... That's what I would do anyway....
To do so, simply drain the heating circuit.... The auto-air vent unscrews from the pump body.... assemble in reverse......
I'm not sure if the manufacturer provides this as an individual component or if you would need to get the full pump body... Not sure of the part number for the auto-air vent, but pump assy is E66 431 ....

Remove the air vent & try cleaning it, maybe leave it to soak in some descaler for an hour or so.
To remove the air vent,
Close the isolation valves of the flow & return of the heating circuit (where the pipes leave the boiler) then drain down the boiler from the drain point on it.
Then you can unscrew the air vent from the pump housing, have a cloth handy just in case there is some water still hanging around. Make sure to cover any electrical contacts & make double sure that no water can get to the circuit board.
If you haven't got the installation & servicing instructions for the boiler you can find them here:

The parts are available as individual items if you need them:
