Ha, you can tell the words my autocorrect is used to, don't often type pcb.
Not the valve the. Can be PCB, but other bits too.
I don't remember this particular model but many boilers of that era had a thermostatic switch which provided pump over run. They are a fairly common failure point on boilers that old.
But the switch is usually inside the combustion chamber which DIYers should not be opening.
