Possible Causes

Failed speed control circuitry on control board, Faulty speed feedback from motor, Incorrect control mode setting

How to Fix / Troubleshooting

Safety first: Turn off power before accessing internal wiring.

  • Check control mode: Ensure the AquaJet pump is set to local control if you are programming speeds at the keypad, or to external control if using automation.
  • Test manual speed change: Attempt to change speed using the keypad. If the display changes but motor speed does not, suspect a control or feedback issue.
  • Inspect feedback harness: Verify the motor feedback cable is secure and undamaged.
  • Replace control or motor: If wiring is intact and the pump still ignores speed commands, the control board or motor assembly may need replacement.
