How to Fix / Troubleshooting

Safety first: Water inside an EV charger is dangerous. Turn off the charger at the consumer unit immediately and do not use it.

User steps:

  • Visually inspect the outside of the unit for cracks, missing screws, or obvious gaps around the cable entry.
  • Do not attempt to dry the inside with a hairdryer or heater; this can worsen damage.

For a technician:

  • Isolate power and open the unit.
  • Dry the interior thoroughly using lint‑free cloths and gentle ambient air; do not use high heat.
  • Inspect for corrosion on the main control PCB, terminals, and socket; replace any damaged components.
  • Replace the front cover gasket, cable gland, or enclosure if compromised, and reseal according to Andersen IP rating requirements.
