Zappi displays E013, no charging, often after long idle periods

Safety first: Do not use the charger if insulation resistance is low; this is a shock risk.

• 1. Inspect for moisture: Check the Type 2 plug/socket and cable entry points for signs of water, condensation, or green/white corrosion.
• 2. Dry the components: If moisture is present, disconnect from supply, remove the cable (if socketed), and allow all parts to dry thoroughly in a warm, dry environment.
• 3. Visual cable check: Look for cracks, UV damage, or cuts along the tethered cable. Replace if any damage is found.
• 4. Test with another cable/vehicle: If possible, use a different cable and EV to see if E013 persists. This helps isolate whether the fault is in the charger or external components.
• 5. Professional insulation test: An electrician can perform an insulation resistance test on the output circuit and cable to confirm integrity.
• 6. If external parts are good: The internal insulation monitoring circuit on the main PCB may be defective and require replacement.
