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.
