Bosch EV charger shows E701 and charging is disabled; may be associated with DC leakage detection.

Safety first: DC leakage faults are serious. Do not bypass or defeat safety features.

• Test with another EV: If possible, connect a different vehicle. If E701 only occurs with one vehicle, have that vehicle inspected by a dealer.
• Power reset: Turn OFF the breaker for 5 minutes, then ON. Some sensors re-calibrate at power-up.
• Avoid extension devices: Do not use adapters or extension cords between the Bosch charger and the vehicle; they can affect leakage detection.
• Service if persistent: If E701 occurs with multiple vehicles, the internal DC residual current sensor or its circuitry is likely faulty and must be replaced by a technician.
