It seems that the error code "Err6" on a Tanita KD-300 scale indicates that there is a problem with the measurement sensors or the internal circuitry of the scale. This could occur due to a number of reasons, such as a buildup of dirt or moisture on the sensor, a loose connection, or an issue with the battery or power supply. One potential solution is to try cleaning the sensor and making sure it is properly connected. If the issue persists, you may need to contact customer support or consider having the scale repaired. It is worth noting that the Tanita KD-300 model is an older model, and some of the solutions mentioned in the search results may not be applicable to your specific issue. It is recommended to consult the user manual or contact customer support for more information on troubleshooting the issue.
