Technical description: The burner control unit KIM (boiler identification module) is faulty
What causes this fault?
This fault occurs when the boiler's main computer loses communication with its internal identity chip, which stores the specific settings for your model. The most common reason is an electrical failure within the plug-in memory module or a malfunction on the main circuit board that prevents it from reading the necessary data. Without this connection, the boiler shuts down because it no longer knows its own safety limits or operating parameters.
