Safety first: Overvoltage can damage insulation and components. If you suspect miswiring, do not re‑energize until wiring is verified.

Step 1 – Measure supply voltage: Have a qualified electrician measure line‑to‑line and line‑to‑ground voltages at the charger input. Confirm they match the nameplate rating (typically 208–240 V).
Step 2 – Inspect surge module: With power OFF, open the enclosure and locate the surge protection device (SPD/MOV board). Look for cracking, charring, or bulging components.
Step 3 – Reset (if applicable): Some SPDs have a resettable indicator or fuse. Replace any blown fuses with identical ratings only.
Step 4 – Power cycle: After confirming correct voltage and replacing any obviously failed SPD, restore power and check if E06 clears.
Step 5 – Board replacement: If the SPD and wiring are correct but E06 persists, the input filter or measurement circuit on the main control board may be damaged and require replacement.
Preventive step: Consider installing a whole‑home surge protector upstream to protect the Electrify America charger from future events.
