Machine malfunction?
I have a JUKI HZL 400 I have had it for 1.5 years and use it weekly for several hours, no heavy duty sewing. I turned it on today and it only sewed in reverse and very small stitches which appear to be zigzag. I shut it off, rethreaded it, changed the bobbin, the needle, changed stitches, pressed the reverse button and it still sewed in reverse. Does anyone have any other suggestions before I bring it in for repair?
