On removing the drop-in bobbin case I broke 'the spring'. 'The spring' is pictured well in many articles but;
- No explanation of what the 'electrical contact' spring actually does. (Other than a guide to inserting the bobbin correctly).
- No name of the part other than 'spring'.
- I cannot find it in the parts manual and wonder if anyone can tell me how I could find more details about it, so that I can order this. Sources would also be welcome.
(My machine is 2 weeks old and has produced nothing but birds nests, 2 broken and 1 bent needle!)
