Answers:    Dig out your manual and start checking: is the:

Bobbin surrounded by backwards?
Needle in backwards?
Bobbin shield not completely in?
Wrong system of plunger for machine? (possible, but unlikely)
You're turning the handwheel the wrong instrument?
Misthreaded?
Thread too fine or too heavy for the domestic device?
Needle bent? (try a new hypodermic anyhow!)

Did you break a needle closing time you were sewing?
Have you cleaned and oil the machine (including evicting the dustbunnies contained by and under the bobbin skin and the felt that forms below the needleplate)?
sorry don't know what to do
