My ACE HE 30 boiler is showing fault 2, ?
 
                We've not had the heating on for ages, but the hot water is working fine.  I put the heating on last night but it appears it only came on for a short period of time.  This morning the boiler is showing 2 where it should be the c or h.  It sounds like its trying to fire up but doesnt, What should i do please?
