You've got a pressurised system by the sound of it, usually between 1 and
2.5 bar (1 when cold, up to 2.5when hot - heat expands the water.)

it might be you have a massive airlock - have you bled off air from the
radiators? but it sounds like a safety feature has erronously triggered.

Not wishing to be the harbinger of doom, but my understanding of the
"overflow" pipe is that it's there to release excess system pressure - e.g
when the boiler just keeps on heating the water and might explode. It
sounds like the valve that lets excess pressure out has opened, and while
it's open the boiler won't fire up as a safety feature.

I'd call a plumber sharpish, with parts delays and all it might be days
before it's fixed?

good luck anyway...
