An error code "U12" (electrode unit is up) occurred during operation, and I contacted the manufacturer. They responded that "there is a possibility of improvement by replacing the electrode unit." Therefore, please purchase on the assumption that the electrode unit will be replaced. If the same error occurs even after replacement, please contact the manufacturer yourself.
