Air locks in cdi classic boilers

[mutley racers]

Hi all. I believe I have an air lock in the above boiler on the pump side. Flow to diverter gets red hot and just cuts out. Even on the hot water. I believe I have had this before. Has anyone else and have you come across a way to get rid of it without dismantling the return side.

Cheers

Hex blocked never had an airlock in a hex that wouldn't move with the pump
