Why did you have a new 3 port valve?

If the pumps kicking in, you need to check the wiring from the wiring centre to the boiler.

Is there any sign of live current at the boiler? eg a light on?

Check any fuses at the boiler as well.

see this every day, but if im wrong im sorry.
Blocked pipework where the cold feed tees into the return and vent.
Renew pipe there and system should run but if this works you badly need a power flush!!!
