In the following subsections, we will address possible problems that you may encounter with the Janome Sewist 725s sewing machine and provide solutions to troubleshoot and resolve these issues. Let’s explore how to keep your sewing machine in top condition.
Common Problems and Troubleshooting for Janome Sewist 725s
1. Bobbin Thread Tension Issue
Description of the problem: The stitches on your Janome Sewist 725s may appear uneven or loose on the underside of the fabric, indicating a bobbin thread tension problem.
Cause of the problem: Incorrect bobbin tension can result from an improperly wound bobbin or a misaligned bobbin case.
Troubleshooting:
- Ensure the bobbin is wound correctly and inserted into the bobbin case without any tangles or loose threads.
- Check the bobbin tension by pulling the bobbin thread through the bobbin case. It should have a slight resistance but still pull smoothly.
- If the tension is too loose, adjust the bobbin tension screw slightly clockwise. If it’s too tight, adjust it slightly counterclockwise. Test with scrap fabric until the tension is balanced.
2. Skipped Stitches
Description of the problem: While sewing, you notice that the Janome Sewist 725s skips stitches, leaving gaps in the fabric.
Cause of the problem: Skipped stitches can be caused by a dull or bent needle, incorrect needle size for the fabric, or improper needle insertion.
Troubleshooting:
- Start by replacing the needle with a new one. Make sure to use the appropriate needle size and type for the fabric you are sewing.
- Insert the needle correctly, ensuring it is pushed all the way up and tightened securely.
- Check the fabric feed and adjust the presser foot pressure if necessary to ensure smooth fabric movement during sewing.
3. Thread Jamming in the Machine
Description of the problem: The thread frequently gets jammed or tangled inside the Janome Sewist 725s, causing sewing disruptions.
Cause of the problem: Thread jamming can occur due to incorrect threading, using low-quality or old thread, or lint buildup in the machine’s bobbin area.
Troubleshooting:
- First, turn off the sewing machine and gently remove the tangled thread from the machine, including the bobbin area.
- Rethread the machine following the correct threading path as per the Janome Sewist 725s manual.
- Use high-quality thread that is suitable for your fabric type, and avoid using old or weak thread.
- Clean the bobbin area regularly, removing any accumulated lint or debris that might be causing the jamming.
4. Uneven Feed Dog Movement
Description of the problem: The feed dogs on the Janome Sewist 725s are not moving smoothly, causing inconsistent fabric feeding.
Cause of the problem: The feed dogs may be dirty, obstructed, or the machine’s drop feed lever is in the wrong position.
Troubleshooting:
- Ensure the drop feed lever is in the correct position (usually up) for regular sewing.
- Turn off the machine and clean the feed dogs using a soft brush to remove any lint or debris.
- If the feed dogs still don’t move smoothly, you may need to have the machine serviced by a qualified technician to address any mechanical issues.
5. Sewing Machine Needle Breakage
Description of the problem: The needle on your Janome Sewist 725s breaks frequently during sewing.
