Display shows P1 and the primary massage pump does not start or runs erratically.

Safety first: Turn off power at the breaker before touching the pump or control pack.

• Check pump thermal reset: Allow the pump to cool for 30–60 minutes. Some motors have an internal thermal protector that will reset automatically once cooled.
• Inspect wiring: Verify that the Pump 1 cable is firmly connected at both the motor junction box (if accessible) and the Aquavia control board.
• Listen for motor noise: Restore power and briefly command Pump 1 on. If you hear only a hum, the motor may be seized or the capacitor may be faulty.
• Replace pump or board: If the pump is confirmed faulty, replace the Pump 1 assembly (wet end and motor). If the pump runs when powered directly but not via the control pack, the Pump 1 relay on the board is likely defective and the control board should be replaced.
