I've a Halstead Ace High that had problems with DHW not working. Put inline filter (spiratech) changed DHW h/e. Ran with Fernox F3 for 1 week and all was fine. Drained system, refilled with F1 inhibitor added. Boiler worked fine for a few short water draws and heating fired. looked good for a bit. Now boiler won't fire and looks like pcb. Except, left it calling for heating and sudden I heard boiler fire up. Any ideas what might be going on here?

Think I've now sorted. Gas safe man wanted to replace pcb for DHW fault (was DHW h/e blocked). In swapping out, much if pcb was disconnected to gain access to h/e. Connections were very stiff. Disconnecting, board contact to air flow switch ended up with a dry joint. Touch of solder seems to have solved
