Possible Causes
Corrupted non‑volatile memory on main control board, Failed real‑time clock chip, Low backup battery on control board (if equipped), Interrupted firmware update
How to Fix / Troubleshooting
Safety first: Configuration changes can be done with power on; opening the unit requires turning off the breaker.
- Step 1 – Factory reset: Use the front panel or app to perform a factory reset of the "Electrify Home" charger settings. Reconfigure schedules and test.
- Step 2 – Re‑enter time and date: Manually set the correct time, date, and timezone in the charger or app. Incorrect time can cause E12 in some models.
- Step 3 – Retry firmware update: If E12 appeared after an update, follow the manufacturer’s procedure to re‑apply or roll back firmware.
- Step 4 – Internal battery check (if present): With power OFF and cover removed, locate any small coin‑cell or backup battery on the main control board. If voltage is low, replace with the exact specified type.
- Step 5 – Board replacement: Persistent E12 after reset and firmware repair indicates a failing RTC or memory on the main control board, requiring board replacement.
