Observation:
When power is switched on the boiler will run a self-check which should show the boiler type, gas setup and output for appliance you are working on, as in the image above. If the display does not progress from the initial self check CLICK HERE.
At the same time the fan will start to run and then the display should show the main menu with "ready" next to the tap and radiator symbols indicating the boiler has completed its self check and has entered stand-by, awaiting a request for heat.

Fan will continue to run after self check is complete (up to 4 minutes).
