Error 88 indicates that the upper tension path is not threaded correctly.
Check that the transparent thread path located at the top of the machine is threaded correctly.
Hold thread in both hands and slip under transparent thread guide. While holding the thread securely, pull the thread towards you and then slip it back and forth like you were flossing. You should hear or feel two clicks as the thread slips past the thread guides.
If that doesn't work, check for any buildup of lint or dross that may be affecting the free movement of the machine.
If the thread is correctly fitted and tensioned correctly, and the machine is clean, then there is some other sensor fault and the machine will require a service.
