Possible Causes

Two phases reversed at AquaFlo motor terminals, Miswired contactor output, Incorrect reconnection after service

How to Fix / Troubleshooting

Safety first: Turn off and lock out the three-phase supply before changing any wiring.

  • Confirm rotation: Observe water flow and motor fan direction. Reverse rotation results in low flow and unusual noise.
  • Swap two phases: At the motor terminal block, swap any two of the three incoming phase conductors (e.g., L1 and L2).
  • Test operation: Restore power and verify correct rotation and normal flow.
