If your Wii was bricked, it wouldn't be able to turn on. You would probably know if it was hacked or modded.
The code has to do with a problem with your connection, so maybe your Wii is damaged in that way. I would get a newer game (Kirby's Dream Collection) and let the game update your console.
If you purchased you Wii recently, you shoudl be eligible for a free repair. To find out if you qualify, call Nintendo at 1-800-255-3700.
