Your boiler is currently stuck in a temporary startup phase and is waiting for everything to be ready before it begins heating.

Current status: Status code.

What causes this fault?

This code appears when the boiler is performing its internal self-checks and preparing its components before officially starting a heating cycle. It is a normal part of the startup sequence and usually indicates the system is simply waiting for a sensor or fan to reach the correct operating state. If the code stays on the screen, it typically means the control board is waiting for a signal that isn't arriving.
