Charger shows E15 and refuses to start; often described as ‘meter error’ on smart metered models.

Note: On some models, charging is blocked if the internal meter is not functioning.

• Power‑cycle: Turn off the charger at the breaker for 5 minutes, then restore power and check if E15 clears.
• Check backend/app: Ensure that the charger’s firmware is up to date and that any required meter initialization has been completed.
• Technician inspection: A technician should open the unit, verify that the internal meter module is powered, reseat its communication cable, and check for error LEDs on the meter (if present).
• Replace meter module: If the meter is non‑responsive or fails self‑tests, it must be replaced with the correct Amperfied‑approved MID meter module.
