I looked in the manual for this machine, and I can't find out what "E2" means to your machine. However, there IS a list of FAQ at the back of the manual that is generally helpful. The first thing I would do, though, is turn off the machine, push the bobbin winder spindle all the way to the right to engage it, then firmly push it to the left. When you engage the bobbin winder, it activates a clutch that diverts power to the winder; that clutch might not be totally disengaged. Also, make sure your buttonhole lever is all the way up, and you have not selected the twin needle function. You might want to contact Singer through their FB account and ask what E2 means.

pl open the entire bobbin housing two scrwes with suitable screw driver and clean .test the latch on the bobbin case,look for steel tension strip screw replace the unit ,also replace needle

Chances are there is thread stuck in the bobbin case area, take it all out and clean it.

Look on line bring up the make and model and they might have that there when you look up the singer, or call the manufactor.

Change needle
Clean under needle plate where feed dogs are for lint

if the bobbin is top loading they will flop around some when the start getting close to empty

Something is likely wrong with your needle. replace it, making sure it is well seated in the needle bar... also make sure you are orienting the needle in the correct direction for your machine. Good luck
