Possible Causes

Corrupted firmware in main control PCB, Damaged EEPROM or microcontroller, Power surge damage, Loose display/control panel ribbon cable

How to Fix / Troubleshooting

Safety: Unplug the cooker before opening the housing. Do not short any PCB contacts.

  • Power reset: Unplug the unit for at least 15 minutes to allow capacitors to discharge. Plug back in and test.
  • Check power source: Try a different wall outlet and avoid using extension cords or power strips that may cause voltage drops.
  • Inspect control connections: Remove the top or front panel to access the control PCB. Reseat any ribbon cables between the display board and main PCB.
  • Look for surge damage: Examine the main PCB for burnt components, cracked ICs, or bulging capacitors.

If E9 persists and there is evidence of PCB damage or firmware corruption, the main control PCB must be replaced. Firmware reprogramming is typically not supported for home users.
