Why does the upper thread keep breaking on my W6 N 1235-61 Sewing Machine?

The upper thread may be breaking due to several reasons. Ensure the upper thread is threaded correctly, and it is not tangled. Also, check that the spool is inserted correctly and that you're using the correct needle. If the CB hook is damaged, contact customer service.
