Charger shows E19 and refuses to start; often after a configuration change or new installation.

Safety first: Configuration changes can be made with power on; do not open live power sections.

• Step 1 – Restore defaults: Use the menu or app to restore factory configuration on the "Electrify Home" charger.
• Step 2 – Reconfigure step‑by‑step: Set only essential parameters (service amperage, Wi‑Fi, basic schedule) and test charging before enabling advanced features.
• Step 3 – Verify region/grid: Ensure the charger is set to the correct country/region and grid type (e.g., split‑phase vs. single‑phase) as required.
• Step 4 – Check hardware label: Compare the charger’s nameplate rating with the configured maximum current. Do not exceed the hardware rating.
• Step 5 – Firmware and support: If E19 persists, update firmware and contact Electrify Home support; the main control board may have an internal parameter fault.
