Charger refuses to start; FLO app or LED pattern indicates E02 ground fault / GFCI trip.

Safety first: Do not bypass or defeat ground-fault protection. Turn OFF the breaker before inspection.

• Check for moisture: Inspect the J1772 connector for water, condensation, or snow/ice. Gently dry the connector with a clean, dry cloth. Allow it to air dry for at least 30 minutes before retrying.
• Inspect the cable: Run your hand (visually, not gripping tightly) along the cable length. Look for cuts, abrasions, or crushed sections. If any copper is visible or the cable feels soft/flat in one area, discontinue use and plan to replace the cable assembly.
• Try another parking position: If the connector has been lying in a puddle or on wet ground, move the vehicle and keep the connector off the ground using the holster.
• Reset the charger: Turn OFF the breaker for 5 minutes, then turn it back ON. Attempt to charge again.
• If E02 recurs with multiple vehicles and in dry conditions: The internal GFCI sensor or associated circuitry on the main control board may be defective. Contact a qualified technician to test and replace the GFCI sensor module or main control board as required.
