Your boiler has encountered a minor glitch and is currently pausing briefly before attempting to restart itself automatically.

DIY fix possible

Wait up to 10 minutes to see if the boiler clears the error and restarts on its own.If the flashing continues, turn the selector switch to the reset position for five seconds and then back to 'On'.Ensure your decorative cupboard or airing cupboard area has enough ventilation and is not blocked by stored items.
