Charger shows E11 and cannot connect to Wi‑Fi or the mobile app; charging may still work locally.

Safety first: Network troubleshooting does not require opening live power sections, but turn off power if you remove covers.

• Step 1 – Reboot the charger: Turn the breaker OFF for 2 minutes, then ON. Many communication faults clear after a full power cycle.
• Step 2 – Check Wi‑Fi signal: Use a phone at the charger location to verify strong Wi‑Fi signal. If weak, move the router or add a Wi‑Fi extender.
• Step 3 – Re‑enter network credentials: Using the "Electrify Home" app or front panel, forget and re‑add the Wi‑Fi network. Ensure the correct SSID and password are used and that the network is 2.4 GHz if required by the charger.
• Step 4 – Inspect antenna (if external): With power OFF, ensure any external Wi‑Fi antenna is firmly screwed in and the internal antenna cable is connected to the communication board.
• Step 5 – Firmware update: If possible, update firmware via USB or local method as described in the manual. If E11 persists, the Wi‑Fi/communication board may need replacement.
