Janome Sewing Machine E2 Error — Bobbin Sensor Fault

What Does This Error Mean?

E2 means the bobbin winder is in the engaged position — pushed to the right, ready to wind a bobbin — when you're trying to sew normally.
The machine refuses to sew until you push the winder back to the left.
It's a quick fix and not a fault.

Affected Models

  • Janome HD3000
  • Janome MC6650
  • Janome HD1000
  • Janome 4120QDC
  • Janome MC9450

Common Causes

  • Bobbin winder pushed to the right (engaged position) instead of the left
  • Bobbin winder spring weak — slips back to engaged on its own
  • Bobbin still on the winder spindle from a previous wind
  • Bobbin sensor on the winder shaft contaminated
  • Sensor failed (uncommon)

How to Fix It

  1. Push the bobbin winder all the way to the left.

    Look at the top of the machine, on the right side.
    The bobbin winder spindle should be slid fully to the left when sewing.
    If it's to the right, the machine reads it as 'winding mode' and refuses normal stitches.

  2. Remove any bobbin from the winder.

    If a bobbin is sitting on the winder spindle, take it off.
    Some Janome models throw E2 when a bobbin is on the spindle even with the winder pushed left.
    This isn't a fault — the machine wants the spindle clear before it'll sew.

  3. Try a few stitches on scrap fabric.

    Once the winder is left and the spindle is clear, press the foot pedal.
    The machine should sew normally.
    If E2 persists, the winder spring or sensor is faulty.

  4. Check the spring on the winder mechanism.

    If the winder slides back to the right by itself, the spring is weak.
    You can usually see this happening when you push it left and watch.
    Service can replace the spring or the whole winder mechanism for $30–$80 depending on the model.

Frequently Asked Questions

Why does Janome lock out sewing when the winder is engaged?

Two reasons.
First, sewing while the winder is engaged could damage the winder mechanism.
Second, the bobbin race is in a different position when winding — sewing in that position would jam.
The lockout protects both you and the machine.

Can I disable the bobbin winder lockout?

No — and you shouldn't want to.
It's a basic safety feature on every modern sewing machine.
If you're getting frequent E2 events because the winder slips, the spring needs replacing — that's the right fix.
