# Known Bugs List

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

  • MAC address of network card is set to 00:80:E1:00:00:01

    Solution: Update EL 2.1 firmware to version 1.2.1-fix2 or higher.

  • Incorrect command statuses

    Solution:

    • If send Start when EL is already started, command status is completed - actually it is ignored.

    • If send Maintenance off during draining or refilling in Maintenance mode, command status is ignored - actually is failed.

  • Fan F103A turns off after exit from Maintenance Mode.

    Solution:

    • Reboot electrolyser using cloud (find the device in Enapter Cloud (opens new window) and execute Reset command (Commands > Electrolyser > Reset) or do system power restart (turn off it and restore power back).

    • Reboot electrolyser using Mobile App.

  • 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.
