# Known Bugs List

The list below contains the most important problems in the firmware and their solutions.

  • Anti-freeze routine bug - In maintenance mode the anti-freeze routine can start even if the electrolyte tank is empty. The absence of water in the tank in such a situation can lead to overheating and damage to the tank. When this occurs, there is a possibility of KOH leakage within the electrolyser during the next refilling of the internal process liquid tank. Please note that this damage will occur only when the device is left powered on in maintenance mode for extended times, without electrolyte, and at low ambient temperatures below 10 °C.

    Solution: Update the firmware to version 1.4.0 or above. Additionally, ensure that the electrolyser is not left unattended when it is in maintenance mode. To update your device, navigate to Device Info -> Firmware and press the Check for Updates button. If you do not see an available update, you can contact our support team at support@enapter.com.

  • The system stops calculation of total produced H2 after 524288.

    Solution: Update the firmware to version 1.6.0 or above. To update your device, navigate to Device Info -> Firmware and press the Check for Updates button. If you do not see an available update, you can contact our support team at support@enapter.com.
