Eliminate Knots Underneath: The Ultimate Guide to Sewing Machine Troubleshooting

Sewing enthusiasts often encounter the frustrating problem of thread knotting underneath the fabric, hindering their smooth sewing experience. Understanding the reasons behind this issue is crucial to resolve it effectively. This comprehensive guide will delve into the various causes of knotting underneath and provide practical solutions to restore your sewing machine‘s optimal performance.

Common Causes of Thread Knotting Underneath

1. Incorrect Threading:

• Ensure the thread is correctly threaded through all thread guides and the tension discs.
• Refer to your machine’s manual for the specific threading sequence.

2. Misaligned Bobbin:

• The bobbin should be inserted correctly into the bobbin case, with the thread unwinding smoothly.
• Check if the bobbin is properly seated and not rubbing against the bobbin case.

3. Loose or Damaged Tension Discs:

• Worn or damaged tension discs can fail to maintain proper thread tension, causing the thread to tangle.
• Inspect the discs for any cracks or chips and replace them if necessary.

4. Improper Needle Size:

• Using a needle that is too large or too small can disrupt thread flow and lead to knotting.
• Select a needle that matches the fabric thickness and thread size.

5. Dirty or Oiled Parts:

• Accumulation of dust, lint, or oil on machine components can hinder smooth thread movement.
• Regularly clean and lubricate the machine according to the manufacturer’s instructions.

6. Incorrect Thread Type:

• Not all threads are created equal. Using a thread that is too thick, too thin, or not compatible with your machine can result in knotting.
• Choose a thread recommended for your machine and the fabric you are sewing.

7. Tension Imbalance:

• Improper tension settings between the upper and lower threads can create loops that tangle and knot.
• Adjust the tension dials according to the fabric and thread combination.

Troubleshooting and Solutions

1. Check Threading:

• Re-thread the machine from the spool to the needle, ensuring it follows the correct path.

2. Align Bobbin:

• Remove the bobbin and reinsert it correctly, making sure it fits snugly in the bobbin case.

3. Inspect Tension Discs:

• Examine the discs for any damage. If they appear worn or cracked, replace them with new discs.

4. Adjust Needle Size:

• Consult your machine’s manual to determine the appropriate needle size for your fabric and thread.

5. Clean and Lubricate:

• Use a soft brush or compressed air to remove dust and lint from the machine. Lubricate moving parts as per the manufacturer’s guidelines.

6. Select Proper Thread:

• Choose a thread that is compatible with your machine and suitable for the fabric you are sewing.

7. Adjust Tension:

• Refer to your machine’s manual to set the correct tension for the fabric and thread combination.

Preventing Knotting Recurrence

• Regularly clean and maintain your sewing machine to prevent dust and lint accumulation.
• Store thread in a dry and protected environment to prevent tangles and weakening.
• Use high-quality thread that is appropriate for your machine and fabric.
• Practice proper threading techniques and always double-check your threading before sewing.
• Avoid sewing over thick seams or multiple layers of fabric, which can strain the thread and cause knotting.
