Stuck open motorised valve normally first suspect.

Near pump or in cyl cupboard usually.
No fixed place

I found it what do I do to it see if valve stick

Likely the valve works, but the micro switch inside is stuck, but changing the V3 micro switch is not really possible, so if head will come off, change head.

A light tap may free switch but only temporary it will need renewing.
