Probable Cause: Battery voltage doesn't match

Steps to Solve:

1. Change the Battery

Probable Cause: Battery voltage is too low/ Power cable connection is bad

Steps to Solve:

1. Check if the connections are bad, if the connection is checked, try restarting the motor by long pressing the power button
2. If the step one doesn't work, change the battery

Probable Cause: Battery voltage doesn't match

Steps to Solve:

1. Check if the battery mode is correct
2. If the step one doesn't work, change the battery

Probable Cause: Battery voltage is too low/ Power cable connection is bad

Steps to Solve:

1. Check if the connections are bad, if the connection is checked, try restarting the motor by long pressing the power button
2. If the step one doesn't work, change the battery

Probable Cause: Motor runs outside of water for too long time / Drive PCB didnt get installed properly

Steps to Solve:

1. Stop the motor, wait unitl the motor gets cooled
2. Long press the power button to reset the motor

Probable Cause: Environment temperature is lower than -20 degree / Faulty sampling component

Steps to Solve:

1. Bring the motor to a warmer place
2. If the first step doesn't work, this error is not recoverable

Probable Cause: Motor runs outside of water for too long time / Drive PCB didnt get installed properly

Steps to Solve:

1. Stop the motor, wait until the motor gets cooled
2. Long press the power button to reset the motor

Probable Cause: Environment temperature is lower than -20 degree / Faulty sampling component

Steps to Solve:

1. Bring the motor to a warmer place
2. If the first step doesn't work, this error is not recoverable

Probable Cause: Motor runs outside of water for too long time / Drive PCB didnt get installed properly

Steps to Solve:

1. Stop the motor, wait unitl the motor gets cooled
2. Long press the power button to reset the motor

Probable Cause: Environment temperature is lower than -20 degree / Faulty sampling component

Steps to Solve:

1. Bring the motor to a warmer place
2. If the first step doesn't work, this error is not recoverable

Probable Cause: Rotor zero position detection failed / Positioning component touched rotor / Motor shaft bent

Steps to Solve:

1. Not recoverable

Probable Cause: Motor stalled due to external force applied

Steps to Solve:

1. Check the motor and remove any obstacles
2. Long press the power button to reset the motor

Probable Cause: Motor has slight short circuit on coils / Motor phase currents are very not balanced

Steps to Solve:

1. Long press the power button to reset the motor
2. If the Step one doesn't work, this error is not recoverable

Probable Cause: Faulty PCB

Steps to Solve:

• Long press the power button to reset the motor
• If the Step one doesn't work, this error is not recoverable

Probable Cause: Faulty PCB

Steps to Solve:

1. Not recoverable

Probable Cause: N/A

Steps to Solve:

Probable Cause: Communication signal is weak

Steps to Solve:

1. Check if the connections are bad, if the connection is checked (especially, make sure the screw on the connectors is tightened)
2. Long press the power button to reset the motor

Probable Cause: Motor power cables are disconnected

Steps to Solve:

1. Not recoverable

Probable Cause: Faulty PCB

Steps to Solve:

1. Not recoverable

Probable Cause: Faulty PCB

Steps to Solve:

1. Not recoverable

Probable Cause: Rotor zero position detection failed / Faulty PCB

Steps to Solve:

1. Motor needs to apply factory setup
2. If the Step one doesn't work, this error is not recoverable

Probable Cause: Singal cable COMPLETELY disconnected

Steps to Solve:

1. Not recoverable

Probable Cause: Beeping sounds, with and with out error codes present

Probable Cause: Full screen dashes or last two lines of controller dashes - usually after an error code and recalibration.
