Splitvolt EV charger displays E06 and will not charge; may appear immediately when powered on, even with no vehicle connected.

Safety first: A missing or faulty ground is hazardous. Do not use the charger until the ground issue is resolved.

• Test outlet ground: Use a receptacle tester or multimeter (qualified persons) to verify that the 240V outlet has a proper equipment ground. If the tester indicates an open ground, contact a licensed electrician to correct the wiring.
• Inspect plug ground pin: With power OFF, unplug the Splitvolt charger and inspect the ground pin for bending, corrosion, or damage. Ensure it is firmly attached and not loose in the plug body.
• Check panel connections (electrician only): Have an electrician verify that the circuit’s ground conductor is properly landed in the service panel and that there is no corrosion or loose connection.
• Try another outlet: If your charger is portable and you have another properly wired 240V outlet, test there. If E06 persists on a known-good circuit, the internal ground monitoring circuit may be defective.
• Do not bypass ground: Never use adapters that defeat the ground pin. If internal failure is suspected, arrange for professional service or replacement.
