Possible Causes

Brownout or surge damage to main PCB, unstable power supply, failing internal power supply circuit, loose power connector to control board

How to Fix / Troubleshooting

Safety first: Disconnect power before accessing the main control board. Use a surge protector to protect electronics.

  • Step 1 – Power reset: Unplug the appliance for 10–15 minutes, then reconnect. Observe if E9 returns.
  • Step 2 – Check outlet: Verify the wall outlet voltage is within specification using a multimeter. Avoid using extension cords.
  • Step 3 – Inspect main PCB: Access the main control board compartment. Look for burnt components, discoloration, or loose connectors.
  • Step 4 – Reseat connectors: Carefully unplug and replug the main harness connectors to ensure good contact.

If E9 persists and visual inspection shows damage, the Fisher & Paykel main control board likely needs replacement by a qualified technician.
