The E-E2 error code on a Brother embroidery machine typically indicates a problem with the machine’s thread tension. This error can occur if the machine is not properly threaded, if the thread tension is too loose or too tight, or if the thread is tangled or caught.

To fix the E-E2 error, you can try the following steps:

1. Power off the machine and unplug it from the power source.
2. Check the thread path to make sure it is properly threaded through all of the necessary guides and tension disks.
3. Check the tension disks to make sure they are clean and free from debris or thread.
4. Adjust the thread tension to the recommended setting for your project.
5. Check the thread to make sure it is not tangled or caught in the machine.

Possible causes for the E-E2 error include improper threading, incorrect thread tension, debris or thread caught in the machine, or a problem with the machine’s tension disks.

If you have followed these steps and the error persists, it may be necessary to take the machine to a Brother authorized service center for further diagnosis and repairs.

It is important to note that attempting to repair the machine yourself can be dangerous and may cause further damage. It is always best to consult with a trained technician for repairs.
