i also got the same issue. hot water is working fine. but no central heating. when i increase the temp from thermostat. red light blinks and then constant green light is there. but boiler doesn't fire up.

any clue please ?

check the timer and diverter valve. u can open the diverter valve manually to heat the central heating
