Display shows E19; charger indicates internal memory or log error

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Corrupted event log storage, Worn flash memory on control board, Incomplete shutdown during write operations, Firmware bug affecting logging

Safety first: No high‑voltage work is required.

Clear logs (if supported): Use the EVgo app or service interface to clear historical logs or reset statistics.
Firmware update: Install the latest EVgo firmware, which may include fixes for logging issues.
Power-cycle: Turn OFF the breaker for several minutes, then ON.

If E19 continues, the main control board’s memory may be failing and should be replaced by an EVgo‑authorized technician.
