Hello and sorry you're having problems. Is this the WII "U" you're referring to here?
Also, how long have you owned it for and when did the problem occur?
Hi my name is ***** ***** I will be happy to assist. The age of the device will help in determining warranty repair.
Which WII model do you have? The original WII, Wii U, etc.?
Do you receive an error with just one disc or do you receive the same error with all discs you try and use?
