My machine beeps Handcoffee when I plug it in or in the middle of a cycle
- Check the power delivered by your cigarette lighter socket. On lorries, 12V sockets are often of low power. The machine requires a minimum of 140W (minimum 12A fuse).
- Do not use extension cords or power strips.
- Test the machine in another vehicle.
If the machine doesn't work in another vehicle either, please contact our after-sales service sav@handpresso.fr to arrange for it to be repaired by our workshop.
