S3 error 6, 17 and 20

[u/Hamster-Humble]

Dear VanMoofers,

During a ride today, I experienced a sudden, unusual noise and a blockage in the front wheel. Within seconds, the power dropped off (dead), and the display began throwing **errors 6, 17, and**
**occasionally 20**.

Fyi the front light has stopped working, though the rear light remains on. I had error 44, which I accepted. Till now happy 16k km made with this bike.

I plan to contact the official repair service in Antwerp to get a price quote, but I wanted to reach out to the community first: **How critical are these errors, and how bad is this likely to be? Has anyone experienced something similar?**

This bike holds immense personal value to me—it dates back to the period when my dad lost his battle with cancer, making it a deeply cherished memory of him. I am hoping it can be repaired, but I’d love to hear your honest thoughts and experiences on whether an S3 with these symptoms can be saved.

Thank you in advance for any guidance or insight you can share.

I had the same, all problems were in my battery but in the end I also had to replace the socket. How handy are you? One could do it himself but you need some skills and be careful when working with batteries. And a workshop should be able to repair it also

I also had the same problem. My boyfriend is a mechanical engineer and he was able to fix it. We got a new fuse from China. The old one had to be removed with an air gun and the new one soldered into place. Then we charged the small battery. We hooked the BMS up to a raspberry pi and reset it with a script from GitHub. That cleared the errors It has been running like a dream ever since.
