Remove the rear cover and you should see four clear plastic disks that are on the end of the drum drive, they are fragile clean them and the sensors and try again.

I had a code that pointed me to the sensors and it was a blade flip on black. You can just blow air on them without taking them out, make sure they are not scratched up.
