Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

A 225 & 227 are HI & LO pressure switch failed open. Only thing a neophyte can do on this one is check the exhaust vent for a blockage. 240 is low flame current. He could try cleaning of the flame sensor (see attached pic for typical) metal rod with steel wool or a green ScotchBrite pad. Beyond these fixes this is a job for a pro. 276 is max number of retries exceeded.
