  • Regularly clean the machine, removing any lint, dust, or debris that may have accumulated in the bobbin area or around the feed dogs.

4. Skipping Stitches on Husqvarna Viking Huskylock 800

Description: Skipping stitches, where the machine fails to form stitches in certain areas, can be a frustrating issue for users.

Cause of the Problem: Skipping stitches may occur due to a variety of factors, including incorrect needle threading, a bent or damaged needle, or insufficient tension.


  • Check the threading of the machine, ensuring that each thread is properly seated in the tension discs and threading guides.
  • Inspect the needle for any signs of damage or bending, replacing it if necessary.
  • Adjust the tension settings on the machine, increasing the tension slightly to see if it improves stitch formation.

5. Motor Issues on Husqvarna Viking Huskylock 800

Description: Some users may experience motor-related issues, such as the machine not turning on or making unusual noises during operation.

Cause of the Problem: Motor issues can stem from various sources, including electrical issues, a malfunctioning foot pedal, or a worn-out motor.


  • Check the power supply and ensure the machine is properly plugged in and receiving electricity.
  • Inspect the foot pedal for any signs of damage or malfunction, replacing it if necessary.
  • If unusual noises persist, it may indicate a problem with the motor itself, in which case professional servicing may be required.

6. Tension Issues

Description: Tension issues can manifest as loose or tight stitches, affecting the overall quality of your sewing.

Cause: Incorrect tension settings, thread misplacement, or dirty tension discs can cause tension problems.


  1. Check the tension settings on your machine, adjusting them as needed to achieve balanced tension.
  2. Ensure the thread is properly placed between the tension discs and threaded correctly through the machine.
  3. Clean the tension discs and surrounding area to remove any debris that may be affecting tension.

7. Needle Breakage

Description: Needle breakage occurs when the needle snaps during sewing, halting your project.

Cause: Using the wrong needle for the fabric, sewing over pins, or hitting a hard object can cause needle breakage.


  1. Ensure you are using the correct type and size of needle for the fabric you are sewing.
  2. Avoid sewing over pins, as this can bend or break the needle.
  3. Inspect the sewing area for any hard objects that may be causing the needle to break, removing them if found.

8. Differential Feed Problems

Description: Differential feed problems can result in uneven feeding of fabric layers, leading to puckering or stretching.

Cause: Incorrect settings, dirty feed dogs, or improper handling of the fabric can cause differential feed issues.


  1. Adjust the differential feed settings to match the type of fabric and desired outcome.
  2. Clean the feed dogs and surrounding area to remove any dirt or debris that may be affecting their function.
  3. Handle the fabric gently, ensuring it is evenly distributed and not stretched or bunched up as it feeds through the machine.

9. Motor Issues

Description: Motor issues can result in the sewing machine not functioning properly or making unusual noises.

Cause: Overuse, lack of lubrication, or electrical problems can cause motor issues.


  1. Allow the motor to cool down if it has been used excessively, as overheating can cause malfunctions.
  2. Regularly lubricate the motor according to the manufacturer’s instructions to ensure smooth operation.
  3. Check the electrical connections and wiring for any signs of damage or loose connections, repairing or replacing as necessary.

10. Stitch Length Irregularities

Description: Stitch length irregularities can result in unevenly spaced stitches or variations in stitch length.

Cause: Incorrect settings, worn-out machine parts, or fabric handling issues can cause stitch length irregularities.


  1. Adjust the stitch length settings to achieve the desired stitch length for your project.
  2. Inspect and replace any worn-out machine parts, such as feed dogs or presser feet, that may be affecting stitch length.
  3. Handle the fabric carefully to ensure smooth and consistent feeding, avoiding pulling or stretching that may affect stitch length.

11. Fabric Fraying

Description: Fabric fraying occurs when the edges of the fabric become unraveled during sewing, leading to messy seams.

Cause: Using a dull or incorrect needle, improper tension settings, or sewing with fabrics prone to fraying can cause fabric fraying.


  1. Ensure you are using a sharp needle appropriate for the fabric type to minimize fraying.
  2. Adjust the tension settings to achieve a balanced tension, preventing excessive pulling on the fabric.
  3. Consider using a fabric stabilizer or serger stitches to reinforce the edges of fabrics prone to fraying.

12. Jammed Loopers

Description: Jammed loopers occur when the loopers, responsible for forming the overlock stitches, get stuck or tangled.

Cause: Buildup of lint or debris, misaligned or damaged loopers, or improper threading can cause jammed loopers.


  1. Clean the loopers and surrounding area thoroughly to remove any lint or debris that may be causing the jam.
  2. Inspect the loopers for any signs of misalignment or damage, adjusting or replacing them as necessary.
  3. Double-check the threading of the loopers, ensuring they are threaded correctly and securely.

13. Needle Threader Malfunction

Description: Needle threader malfunction prevents the automatic threading of the needle, requiring manual threading.

Cause: Misalignment, dirt, or damage to the needle threader mechanism can cause it to malfunction.


  1. Inspect the needle threader for any visible misalignment, dirt, or damage, cleaning or adjusting it as needed.
  2. Ensure the needle is at the correct height and position for the threader to function properly.
  3. If the issue persists, consider using a manual needle threader or threading the needle manually.

14. Stitch Tension Variations

Description: Stitch tension variations result in inconsistent tension across different sections of the seam.

Cause: Uneven fabric thickness, improper threading, or worn-out tension discs can cause tension variations.


  1. Ensure the fabric is evenly layered and fed through the machine to prevent variations in tension.
  2. Re-thread the machine, paying close attention to the threading path and tension discs.
  3. If tension discs are worn or damaged, consider replacing them to maintain consistent tension.

15. Stitch Formation Issues

Description: Stitch formation issues result in irregular or inconsistent stitches, affecting the appearance and durability of the seam.

Cause: Improper machine setup, worn-out or damaged machine parts, or incorrect threading can cause stitch formation issues.


  1. Check and adjust the machine setup, including needle position, stitch length, and tension settings, to ensure proper stitch formation.
