Thread getting caught underneath
Was sewing fine, then started jamming. Thread is getting caught and tangled below the feed dogs, needle bounces up and down, hand wheel won't turn. Tried re-inserting bobbin, same thing happened. Then took apart lower section, pulled out loose thread, which seems to have wrapped itself around the bobbin case. Brushed everything out and put it back together, it did the same thing again. Also tried re-threading upper thread, same results. Have Shark model # 9110.
