Hi.

18 blinks is not a fault code. The LED probably starts blinking because the controller board is faulty, and stops after 18 times because it dies always at the same time. Problem is likely main controller board, you can try testing the board at component level. Check connectors a shorted connector is a common fault that may have unforeseen effects. Test PSU voltages just in case, wrong voltage to controller may fry it and may result in no error code.
