Charger displays E11 and refuses to start; often associated with Wi‑Fi or app connectivity issues.

Safety: Network faults are usually low risk electrically, but always turn OFF power before opening the enclosure.

• 1. Reset network settings:
  • Use the AMPROAD app or front panel to reset Wi‑Fi/Bluetooth settings to factory defaults.
  • Reconfigure the network connection and test.
• 2. Power-cycle:
  • Turn OFF the breaker for 2–3 minutes, then restore power and check if E11 clears.
• 3. Inspect communication module:
  • With power OFF, open the charger and locate the Wi‑Fi/Bluetooth module or communication daughterboard.
  • Reseat the module and check for bent pins or corrosion.
• 4. Firmware compatibility:
  • Check AMPROAD documentation for required firmware versions for the main board and comms module.
  • Update firmware if instructed by AMPROAD support.
• 5. Replace module if needed: If E11 persists and the module shows no signs of life (no status LED, no broadcast), replace the AMPROAD communication module.
