CodeWhat does it mean?Cause and diagnosis (this part)
30Communication fault with the main PCB.The main PCB (65100774) does not establish communication with the panel/display, usually due to a fault in the PCB itself (5V/12V supply, micro or tracks). Check voltages at the display connector, continuity of the harness, and if they are correct, replace the PCB.

Verify the reference 65100774 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part.
What is it used for?
