I can't imagine it would be time to replace my Janome HD3000, since I bought it about six months ago, but from time to time it drives me up the walls. Today, for example, three times the thread broke while I was sewing, and once the needle housing jammed, causing the fabric to stop advancing. Removing and then reinserting the bobbin worked for a while, but then it acted up again. All this while I was sewing two custom orders! Anyone have any ideas as to what might cause these problems? Granted, making sure the bobbin thread is passed counterclockwise through two wafer-thin discs in the bobbin housing is difficult, and I wonder if it isn't engaged properly.
Thanks.
