Inside of the Smart Chef Smart Food Scale contains a mini computer and may require a hard reset occasionally. To reset the Smart Food Scale, use a paper clip, slowly place the pin-head into the reset pin-hole (as shown below), and then gently push down to press the internal mechanical button for a quick second. That's it. If you require further technical support please contact us via the chat button located at the bottom right hand corner of this page or use the contact form HERE.
