Hello, assuming that you have a Worcester boiler, "EA" is a code that indicates flame failure. In other words, the boiler attempted to ignite but was unable to. There are many possible causes of this. You should reset the boiler and see if it happens again. If you tell me the model of boiler then I'll send you a link to the user instructions.
How are you getting on with your boiler?If my answer was helpful, please take a moment to rate me.
