Worcester bosch oil boiler wont fire up

[afair]

My Worcester Bosch oil boiler won't fire up and locks out. I have oil but boiler wouldn't come on this morning - pressed orange lockout light - it fires up then changes to a different fire up sound and locks out. Any ideas?

Is the weather bad there
I have seen mice get in these boilers and get in to fan then when boiler kicks on they get stuck in fan and boiler cuts out?
Just a thought could be lots of things
Could be oil pump?
Could be control box?
Think you better getting in someone to look at it

Sorted the problem - pressed orange lockout 4 times - the last time it worked!!!

there must be a reason it locked out

Think the pipes may have been cold - because I turned thermostat right up to max the last time and it worked!
