E1
Brother Sewing Machine
Severity: ModerateWhat Does This Error Mean?
E1 on a Brother sewing machine means thread has jammed in the bobbin area. The machine stops to prevent damage. Open the bobbin cover, remove tangled thread, and rethread both the top and bobbin threads.
Affected Models
- Brother SE1900
- Brother SE600
- Brother CS7000X
- Brother XR9550
- Most computerised Brother machines
Common Causes
- Thread tangled around the bobbin case
- Bobbin inserted incorrectly
- Top thread not properly threaded through the tension discs
- Wrong bobbin type for the machine
- Lint buildup in the bobbin area
How to Fix It
-
Turn off the machine and remove the fabric.
Do not pull the fabric — you may bend the needle or damage the feed dogs. Cut the thread and gently remove the fabric.
-
Open the bobbin cover and remove all tangled thread.
Remove the bobbin and clean out all thread pieces with tweezers. Check behind the bobbin case for hidden thread.
-
Clean lint from the bobbin area with a brush.
Use the lint brush that came with the machine. Lint buildup causes thread to catch and jam.
-
Rethread the machine completely — both top and bobbin.
Start from scratch. Make sure the top thread goes through every guide and tension disc. Insert the bobbin in the correct direction (check the arrow markings).
Frequently Asked Questions
Why does thread keep jamming?
The #1 cause is incorrect threading — especially the top thread skipping a tension disc. Always rethread with the presser foot UP (this opens the tension discs).
How often should I clean the bobbin area?
After every 3-4 bobbin changes, or whenever you see lint. More frequently when sewing with lint-heavy fabrics like flannel or fleece.
