Why does the thread keep breaking on my Gritzner 788?
- A
  Ashley SellersJul 26, 2025
  If the thread breaks while using your Gritzner Sewing Machine, several factors could be at play. Ensure the needle is correctly threaded. If the thread tension is too tight, adjust it accordingly. Also, double-check that the needle is correctly installed. Inspect the thread spool post and thread tree for any tangled threads and remove them. Finally, ensure you are using a suitable needle for your thread and fabric.
