How to Fix / Troubleshooting

Safety first: Turn off power and do not continue operating the pump while it is chattering or cycling rapidly.

  • Listen for relay noise: With the cover off (and power briefly restored), listen for rapid clicking from the Aquaflow control board, indicating relay chatter.
  • Check supply stability: Verify that the incoming voltage is stable and not dropping when the pump starts.
  • Inspect board: Look for heat discoloration around the relay on the control board.

Relay faults generally require replacement of the control board. Because this involves mains voltage and sealed components, contact a qualified technician.
