Q: What does the error code E1 mean on the E-TWOW Boost ES scooter?

E1 = Overcurrent protection This error appears when the current in the system becomes too high, usually during significant acceleration. The 500W motor of the scooter then stops working for a few seconds to protect the electrical components. How to resolve the E1 error: Simple solution: The E1 error usually disappears on its own when you release the throttle . Just stop accelerating for a few seconds - the system will automatically reset. If the error persists: Wait a few minutes before restarting the scooter. This error can also occur if you are going up a slope that is too steep (beyond the recommended 20°) or if the 36V battery is overheating after intensive use. Let it cool down before continuing. Other error codes for reference: E2 = Control block communication error (resolves by accelerating or braking) E3 = Battery overvoltage (turn off and turn on the scooter) E4 = Communication error between the controller and the display (requires an authorized service center) If the E1 error frequently reappears even after releasing the throttle, contact the official customer service at service@e-twow.com for a complete diagnosis.
