Metal spring for embroidery unit B70 / B79

This original metal spring is a specially manufactured wear part for the hoop mount of the embroidery unit on your Bernette B70 or B79. It establishes the necessary mechanical contact between the hoop and the machine so that hoop detection works and embroidery files can be loaded. Without an intact spring, the screen often displays "No hoop detected," even though the hoop clicks into place correctly.

Why is this important?Precise detection is essential for embroidery – only then can the machine fully and correctly execute the embroidery pattern. The spring transmits tiny movements and creates the electrical contacts necessary for detection. If it's bent, worn out, or broken, the contact fails – you'll recognize typical symptoms immediately.

This replacement part provides you with a new, precisely fitting metal spring. Installation is simple and can be done without special tools – you can also find instructions for disassembly, spring replacement, and reassembly here (support from Makema or Bernette). After the replacement, your embroidery unit will be fully functional again.
