Charger displays E06 and refuses to start; often associated with incorrect wiring or missing ground.

Safety first: A missing or faulty ground is dangerous. Do not bypass ground detection. Have wiring inspected by a licensed electrician.

• Test outlet or supply wiring: Use a receptacle tester or multimeter to confirm correct hot/neutral/ground configuration and continuity back to the panel.
• Inspect ground conductor: With power OFF, verify the ground wire is securely attached to the Zencar ground terminal and to the panel ground bar.
• Check for corrosion: Look for rust or oxidation on ground lugs inside the charger and at the service panel. Clean and retighten as needed.
• Measure ground impedance: An electrician can measure ground impedance; high values can trigger E06. Correct by improving grounding per local code.
• If wiring is correct: The internal ground monitoring circuit on the main control PCB may be faulty and require replacement.
