Possible Causes
Moisture ingress into output wiring or connector, damaged insulation on the tethered cable, contamination or tracking inside the Type 2 socket, faulty isolation monitoring circuit on the PCB.
How to Fix / Troubleshooting
Safety: Low insulation resistance can lead to electric shock. Do not use the charger until it has been tested.
- Step 1 – Visual Inspection: With power OFF, inspect the cable and connector for cuts, abrasions, or signs of water ingress.
- Step 2 – Drying Period: If the charger or cable has been exposed to heavy rain or flooding, allow time to dry in a safe environment. Do not apply external heat sources.
- Step 3 – Insulation Testing (Electrician): Perform insulation resistance tests between line/neutral and earth on the output circuit and cable. Values below manufacturer thresholds indicate a fault.
- Step 4 – Replace Damaged Components: Replace the tethered cable or socket if insulation is compromised. Clean or replace any contaminated parts.
- Step 5 – PCB Check: If insulation tests are good but the charger still reports an isolation fault, the isolation monitoring circuit on the PCB may be defective and require replacement.
