How to Fix / Troubleshooting

Safety first: If the GFCI will not reset, do not bypass it. Turn OFF power at the breaker.

Steps:

  • 1. Operate test/reset: With power ON, press the test button to confirm the unit trips, then press reset. If it does not trip, or will not reset, discontinue use.
  • 2. Inspect mechanism (qualified person): With power OFF and cover removed, check for physical obstruction or damage to the test/reset mechanism.
  • 3. Replace GFCI module: Many Leviton EVSE units integrate GFCI into the main board or a dedicated module. Replace the defective component per Leviton service instructions.
