Unable to read disc message on Wii

The Wii console will not play game discs (disc is not recognized)
System displays either error message "Unable to read disc" or "Disc could not be read"
 

Note

Wii Game Discs are region locked, and can only be played on hardware from the same country where the game was released. (A European game cannot be played on a North American system, for example.)
 

What To Do:

The Wii console is only compatible with Wii and GameCube discs. It is not compatible with DVDs or discs made for other home consoles. Verify that the disc you are inserting is compatible with the Wii system.
An error message may display if the disc is ejected during play. Return to the HOME Menu before changing discs.
Verify that the console is placed correctly.
If the Wii console is lying flat, the game disc slot should be above all three buttons and the SD Card slot.
If the Wii console is standing vertically, the power button should be on the top and the console should be in the stand. Note: Only Wii consoles with model number RVL-001 are intended to be placed vertically. (Learn more)
Verify that the disc is being inserted properly.
If the console is placed horizontally, the disc label will face upwards.
If the console is placed vertically, the disc label will face to the right.
Check the non-printed side of the game disc for dirt or severe damage (such as scratches or cracks).
If the disc is dirty, try cleaning the game disc. (How to)

This can be caused by a dirty laser in the drive. Try cleaning the laser with a q-tip and alcohol. If this does not fix the problem, the laser may need to be replaced. Contact Nintendo and see if the unit is still under warranty.
