The bobbin case keeps popping out. I can only sew for 30 seconds or so and the the bobbin case comes loose. It also sounds a little noisy when sewing. I have checked the groove on the spindle and it seems ok, and also the latch on the bobbin case seems to operate ok. When I insert the bobbin case it snaps in, but seems a little loose. I tried a little oil on the bobbin case, in the latch grooves, and it seemed to work a little better. Sews longer before it pops out again. Do you think I just need a new bobbin case?
Thanks
