What Does Error E1 Mean?
The E1 error on your Chef cooktop indicates a potential failure in the temperature sensor or issues with cookware detection. This error often manifests as the cooktop not heating properly or an erratic display. Common causes include using unsuitable cookware or improper placement. To address the issue, ensure your cookware is induction-compatible and properly centered on the burner. If the error persists, a power reset may help, but further inspection of internal components could be necessary.
