Hi my name is Brian. Our apologies for not replying sooner, I think the reason could be due to this being a difficult question to diagnose. The boiler is showing two faults, Air Pressure Switch and an Overheat fault. If you have got the problem solved now please contact the moderators they can if you wish cancel the question for you. Or can you tell me any events or noises leading up to the breakdown if of course there were any.
Thanks and apologies again. Best regards, Brian
