Verify that line voltage is within 10% of pump rated voltage at the terminal block. Indicates that the internal DC bus voltage is too low. Verify that line voltage is within 10% of pump rated voltage at the terminal block. Also, verify that power supply connections are properly made at the circuit breaker as well as at the terminal block. Indicates that the internal components of the drive have become overheated. Motor airflow path should be checked for obstructions and cleared if present. Check ambient temperature and verify against motor nameplate (50°C/122°F). Indicates that motor current is too high. Check impeller, diffuser, shaft seal, and motor for any issues or binding. Indicates that the drive has lost control over motor shaft rotation. Check impeller, diffuser, shaft seal, and motor for any issues or binding. Indicates that the drive was not able to start the motor.

Contact Hayward Technical Service for additional assistance. Indicates that there are communication problems inside the motor/drive, and that the motor/drive may need to be replaced. Contact Hayward Technical Service for additional assistance. Indicates that the user interface is receiving an error from the motor/drive that it does not understand. Contact Hayward Technical Service for additional assistance. NOTE: All errors can be manually reset by pressing Stop/Resume when the error message is shown, or by cycling power applied to the pump after the error has occurred. Under certain circumstances, the "Drive overload" error can only be reset by cycling power applied to the pump. If the troubleshooting steps listed above do not help to resolve the error condition, then the problem may be internal to the motor/drive.
