Juki 1900 - Error E7

[skytribe 17]

Went to use the machine - bar tacker bound up and stopped gave error code E7. Cleared out the tangle of thread but now I can't get it to clear the error code and every time I try and use it get the same tangle of thread on the bobbin.

Any ideas on how to fix.

1.Pull the top thread out of the needle and lay aside.

2.Remove bobbin case and lay aside.

3.Check hook area for thread between the race/hook.

4.Turn head over to the left (hinge) and look for thread between the knives under the throat plate

5.Run machine through a few cycles without any thread or the bobbin case. This should clear the problem.

If not, the knives have moved out of place.

Thanks MEL

That cleared it, and rethreading and got tensions set up so its working. When I got it powered it seems happy.

When I turn off and repower - sometimes it throws an E7. Try repowering a couple of times and once I get it up and running seems to work fine.

The cable look like it had been squished a bit as someone had crushed the cable running from the control box to the head unit. As it looks like E7 code can also occur with a power fault this may be something I look at replacing.
