I have this big problem. One of our clients has 9406-730 machine. After a power outage, they got an SRC code: A6nn0266 where nn is continuously changing every 1 or 2 minutes. And another thing is it's 5073 expansion unit does have an error code in its panel 1021A300. I also can't log in to the console. What should I do now? badly need your help. Thank you very much. God bless!
