Possible Causes

Failed pump relay on control board, Shorted pump motor, Loose pump wiring at control pack, Incorrect pump voltage configuration

How to Fix / Troubleshooting

Safety first: Shut off power at the GFCI breaker. Pump circuits carry high voltage.

Er3/ERR3 points to a problem in one of the pump circuits.

  • Identify affected pump: Note which pump (Pump 1, Pump 2, etc.) does not respond when commanded from the topside panel.
  • Inspect wiring: At the control pack, check the corresponding pump connector for tightness, heat damage, or discoloration.
  • Test pump motor: If qualified, disconnect the pump and bench-test it or have a technician test for shorts or open windings.
  • Check configuration: Verify that the control board is configured for the correct number and type of pumps for your American Whirlpool model.

Repair may require replacing the pump motor or the control board pump relay, which should be done by a professional.
