how can i fix my glow worm 40ff boiler?

hot water ok but boiler doesn't ignite when central heating is switched on. thermostat is on, but the burner light doesn't come on.

the problem is most likely the mid position valve (y plan) or zone valve (if on s plan) not sending signal back.....replace !
