11. Troubleshooting

11.1. General Problems

Motor Will NOT Start:

1. Make sure the terminal board connections agree with the wiring diagram on the pump data plate label.
2. Be sure the pump is wired for the available field supply voltage (230VAC).
3. Check for and correct any improper or loose wiring connections; open switches or relays; tripped circuit
breakers, or blown fuses.
4. Manually check the rotation of the motor shaft for free movement and lack of obstruction. Correct if
necessary.
Motor Shuts OFF:

1. Check for low voltage or power drop at the motor (frequently caused by undersized wiring). Contact a
qualified professional to verify the electrical connections.
2. If the pump experiences an intermittent power failure short enough to remain power to the controller but not
the pump, the pump will stop the motor. To resume function to the pump PRESS the RUN / STOP key or cycle
power long enough to turn the controller off.
Motor Hums, But Does NOT Start:

1. Impeller jammed with debris. Have a qualified repair professional open the pump and remove the debris.
