Possible Causes
Incorrect wiring of demand response input, Stuck external control relay, Misconfigured demand response settings, Faulty low‑voltage input circuit on main control board
How to Fix / Troubleshooting
Safety first: Low‑voltage control wiring still requires power off before changes.
- Step 1 – Review settings: In the "Electrify Home" app or menu, review demand response or external control settings. Temporarily disable these features and test charging.
- Step 2 – Inspect control wiring: With power OFF, check any external control terminals (e.g., DR, CTL) for loose or shorted wires. Remove external control wires and test the charger standalone.
- Step 3 – Check external device: If a utility or home energy system is connected, verify that its relay or control output is operating correctly and not stuck in a shed/disable state.
- Step 4 – Input circuit test: If E14 persists with all external wiring removed and features disabled, the control input circuit on the main board may be defective.
