What does E007 error mean on my JUKI Sewing Machine and how to fix it?
- J
  Jennifer FisherAug 18, 2025
  The E007 error on your JUKI sewing machine indicates a motor overload. This can happen for several reasons: * The machine head is locked. * You're sewing extra-heavy material. * The motor isn't running. * The motor or driver is broken. To resolve this: * Check for thread entangled in the motor pulley. * Ensure the motor output connector (4P) is properly connected. * Check for any obstructions when turning the motor by hand.

  The E906 error code on your JUKI Sewing Machine indicates an operation panel transmission failure. This could be due to a disconnected operation panel cord or a broken operation panel. To resolve this, check the operation panel connector (CN38) for any loose connections or disconnections. Also, inspect the operation panel cord to ensure it hasn't broken, especially where it might be caught in the machine head.

What does error E813 mean on my JUKI DDL-8700 Sewing Machine and how to resolve it?
- G
  Grace SimonAug 26, 2025
  Error E813 on your JUKI sewing machine signals a low voltage issue. This can occur if the input voltage is lower than the guaranteed level, such as inputting 110V into a 220V SC-500 model, or applying 110V to a 220V box. It can also be caused by internal circuit damage due to prior overvoltage. Check if the voltage is lower than the rated voltage (more than 10% below). Verify that the 110V/220V changeover switch is correctly set. Inspect the fuse and regenerative resistance for any breaks.

Why doesn't the presser foot go up on my JUKI DDL-8700 with the auto-lifter attached?
- M
  mvasquezAug 28, 2025
  If the presser foot on your JUKI sewing machine isn't lifting even with the auto-lifter attached, there are a few potential causes: 1. The auto-lifter function might be turned off. Select “FL ON” using the auto-lifter function selection. 2. The pedal system could be set to KFL. Change the jumper to PFL setting so you can lift the presser foot by depressing the back part of the pedal. 3. The auto-lifter device cord may not be properly connected to the connector (CN37). Ensure the cord is correctly connected.

What causes the E003 error on my JUKI Sewing Machine?
- S
  Steven Williams DDSAug 30, 2025
  The E003 error on your JUKI Sewing Machine indicates a disconnection of the synchronizer connector. This can occur if the position detection signal isn't being input from the sewing machine head synchronizer, or if the synchronizer is broken. Check the synchronizer connector (CN33) to ensure it is securely connected. Also, inspect the synchronizer cord for any breaks, especially where it might be caught in the machine head.

Why does the stop position of my JUKI Sewing Machine vary irregularly?
- R
  Robert SmithSep 1, 2025
  If the stop position of your JUKI sewing machine is inconsistent, it might be because the screw in the handwheel wasn't tightened after adjusting the needle stop position. Make sure to securely tighten the screw in the handwheel.

What does error E811 mean on my JUKI Sewing Machine?
- W
  walkerdavidSep 4, 2025
  Error E811 on your JUKI sewing machine indicates an overvoltage issue. This can happen if the input voltage is higher than the guaranteed level, such as inputting 220V into a 110V SC-500 model, or applying 400V to a 220V (230V) box. Check if the applied power voltage is significantly higher than the rated voltage (more than 10% above). Also, verify that the 110V/220V changeover switch is correctly set. Note that in such cases, the POWER p.c.b may be damaged.

What to do if the touch-back switch on my JUKI DDL-8700 Sewing Machine isn't working?
- S
  Susan RochaSep 6, 2025
  If the touch-back switch on your JUKI sewing machine isn't working, it could be because the presser foot is raised by the auto-lifter device. Try operating the switch after lowering the presser foot. If an auto-lifter device isn't attached but the auto-lifter function is on, select “FL OFF”.

Why does my JUKI Sewing Machine beep and not operate when I tilt it?
- A
  Aaron JacksonSep 8, 2025
  When you tilt the JUKI sewing machine without turning it OFF, the buzzer beeps, and the machine won't operate as a safety measure. To avoid this, always turn OFF the power before tilting the sewing machine.
