Novice in need of help

[diywhy1]

Ok... My ideal classic ff250 boiler keeps cutting out due to (i beleive ) overheating. Every time i fire it up it will gurggle a hell of a lot how do i get rid of this air. Tried the obvious one radiators and bleed tap in airing cupboard which has helped but not cured

Check the pump is running

 

[diywhy1]

Pump is running sweet as a nut

 

[JohnD]

if you bleed the highest radiator in the house, does water squirt out forcefully, and keep squirting?

 

[diywhy1]

No, all radiators are fine

 

[davebgas]

Did you vent the pump though?

 

[diywhy1]

If this is just taking the large screw off the front of the pump then yes, the air (gurggling noise) appears trapped in or just above the boiler

Think you may be in danger of making unfounded assumptions that pump is sound just because shaft is turning

 

[JohnD]

No, all radiators are fine

do you mean it does squirt out forcefully, or do you mean you don't want to check?

Have you checked the header tank has water innit.

Drain some water out of the system with a hose pipe and check the tank is refilling.
