why does my boiler fire up on its own?

I have a worcester greenstar 28ijunior boiler and every so often it fires up on its own(ch not on, no hw demand) and runs for about 1 minute then stops, why is this?

Probably its hot water pre-heat function.

Take a look and see if the "Eco" button is lit up. If not, press and hold for a few seconds then let go. When Eco is lit, the pre-heat is disabled.
