Thread Jumbled Under Fabric When Starting To Sew.

1. Incorrect bobbin threading: Ensure that the bobbin is properly wound and inserted into the bobbin case. Check if the bobbin thread is correctly threaded through the tension spring or any other designated areas as per your machine's manual.

2. Tension settings: Incorrect tension settings can cause the thread to get stuck and create jams. Make sure you have set the upper thread tension to the recommended setting for the type of fabric you're working with. Adjusting the tension slightly up or down can also help troubleshoot the issue.

3. Needle-related issues: Ensure that you're using the correct needle for the fabric you are sewing. A dull or bent needle can cause thread problems. Try changing the needle and make sure it is inserted correctly, with the flat side facing the back of the machine.

4. Cleaning and maintenance: Sometimes, lint or debris can accumulate in the bobbin area, causing thread tension problems. Regularly clean the machine, remove any lint, and oil the designated parts as per your machine's manual.

If the issue persists, it might be helpful to consult the machine's manual or contact the manufacturer's customer service for further assistance. They will be able to provide specific guidance and troubleshooting steps tailored to your Pfaff Tiptronic 2020 machine.

I hope this helps, and best of luck getting your sewing machine back to working smoothly!

Bobbin tension: Check the tension of the bobbin thread. If the tension is too tight, it can cause the thread to get caught and lock up. Adjust the bobbin tension following the manufacturer's instructions. It's also worth ensuring that you're using the correct type and weight of thread for your machine.

Upper thread tension: Improper upper thread tension can also lead to thread locking and jamming. Ensure that the upper thread is threaded correctly through the tension discs and that the tension dial is set appropriately for the fabric you're working with. You may need to adjust the tension to find the optimal setting.

Needle condition: A damaged or bent needle can cause thread issues and machine jams. Check the needle to make sure it's straight and not dull or bent. Replace the needle if necessary, using the correct type and size recommended for your machine.

Thread path: Verify that the upper thread is threaded correctly through all the thread guides, tension discs, and the needle. Make sure the thread is not getting caught on any rough edges or protrusions along the thread path.

Clean and lubricate: Regular cleaning and lubrication of your sewing machine are essential for its proper functioning. Remove any lint or debris from the bobbin area, feed dogs, and thread path. Apply a drop or two of sewing machine oil to the designated points as specified in your machine's manual.

Machine maintenance: If you've tried the above steps and the problem persists, it may be time for a thorough machine maintenance check. Consult your machine's manual or contact a professional technician to have your machine serviced and checked for any mechanical issues.

Remember to consult your Pfaff Tiptronic 2020 user manual for specific instructions and troubleshooting tips tailored to your machine model.
