Tips for Preventing BERNINA Sewing Machine Bobbin Tension Problems

BERNINA sewing machines are known for their quality and reliability, but even the best machines can experience bobbin tension problems. Fortunately, there are a few simple steps you can take to help prevent these issues and keep your machine running smoothly.

Clean and Inspect the Bobbin Case

The bobbin case is the part of the machine that holds the bobbin and is responsible for controlling the tension. It’s important to keep it clean and free of lint and debris. To do this, use a soft brush or compressed air to remove any dirt or dust. You should also inspect the bobbin case for any signs of wear or damage, such as cracks or chips. If you find any, it’s best to replace the bobbin case to ensure proper tension.

Check the Bobbin Thread

The bobbin thread should be the same type and weight as the top thread. If the threads are different, it can cause tension problems. Additionally, make sure the bobbin thread is wound evenly and not too tightly. If the thread is wound too tightly, it can cause the bobbin to jam or the tension to be too tight.

Adjust the Tension

If you’re still having tension problems, you may need to adjust the tension. To do this, turn the tension dial on the machine until the tension is balanced. You can test the tension by sewing a few stitches and checking the back of the fabric. If the stitches are too loose, turn the tension dial clockwise; if they’re too tight, turn it counterclockwise.

Regular Maintenance
