B. Automatic Backtack (Reverse) Not Working

• Symptom: Machine starts sewing without reverse stitches, or reverse lever stays stuck down.
• Fix:
  • Check the Backtack Solenoid connection.
  • Adjust the stroke of the solenoid plunger. If it is too loose, it won't engage the reverse lever. If too tight, it will jam.

Error 8: E-08 / E-8 – Needle Up/Down Position Sensor Failure

• Cause: The machine cannot sense when the needle is at top dead center (TDC). This prevents thread trimming and automatic stop positioning.
• Work / Solution:
  1. Manually turn the handwheel until the needle is fully up. Look through the sensor hole near the handwheel magnet.
  2. Clean metallic debris off the magnet.
  3. Adjust sensor gap: 1–2mm air gap between hall sensor and magnet.
  4. If still failing, replace the Hall sensor IC (housed in the main motor encoder).

First, The Basics – What Errors Does It Show?

From the service manual and real-world factory logs, here are the key codes you’ll meet:

| Error Code | Meaning | How It Feels | |------------|---------|----------------| | E-01 | Foot pedal not returning to zero | Machine thinks you’re pressing the pedal halfway – refuses to start. | | E-02 | Servo motor overload | You tried to sew through 8 layers of denim hem. Respect, but no. | | E-03 | Thread trimmer sensor fail | Trimmer fires but doesn’t reset. Now you have 4 loose threads and a confused face. | | E-04 | Needle position sensor error | Machine forgot if needle is up or down. Spoiler: it’s always wrong. | | E-05 | Low voltage to control board | Happens in old factories with unstable power. Machine goes into safe mode. | | E-06 | Communication error between panel and main board | Buttons work, display shows gibberish. Reboot fixes 80% of cases. | Mastering the Siruba L818F-M1: The Complete Error List

Error 1: E-01 / E-1 – Motor Lock / Overload

• Cause: The machine is mechanically jammed. Thread tangled in the hook, needle strike on the throat plate, or foreign object in the upper knife mechanism.
• Work / Solution:
  1. Turn off power.
  2. Manually rotate the handwheel backward. Does it move? If not, remove the needle and check the hook area.
  3. Clean lint from the rotary hook and feed dog.
  4. Check if the upper knife is stuck against the lower knife (adjust knife timing).

Chapter 5: Advanced – Parameter Settings That Mimic Errors

Sometimes, the machine behaves like it has an error, but it's a misconfiguration. Here are parameters that work like errors:

• P-15 (Minimum pedal speed): If set too high (>800), machine will seem to run away when pedal is in neutral – mistaken for E-04.
• P-30 (Thread trimmer delay): If set to 0, the trimmer may actuate while needle is down, causing E-01.
• P-50 (Motor lock detection time): If set to 2 ms (too sensitive), normal fabric resistance triggers false E-01. Set to 6-8 ms for heavy denim.

To reset all parameters to factory defaults:

1. Turn off machine.
2. Hold down "P" and the "–" button.
3. Turn on machine while still holding.
4. Release when display shows "8888". Press "Enter".
