How to Fix / Troubleshooting

Safety: Disconnect from mains before any disassembly.

  • Soft reset: Unplug the cooker for at least 10 minutes. Press and hold any button for 10 seconds (while unplugged) to help discharge residual power, then reconnect and test.
  • Keypad inspection: Check the control panel for stuck buttons, cracks, or signs of liquid ingress. Gently press each button to ensure it moves freely.
  • Dry moisture: If the panel has been exposed to steam or spills, allow it to dry thoroughly. If possible, remove the front panel and dry the keypad and display board with gentle airflow.
  • Sensor check: If the error appears only when starting certain programs, inspect the associated sensors (temperature, pressure, lid) for loose connections.
  • Board replacement: Persistent generic errors usually indicate a failing main control board or keypad/display board. Replace the faulty board as a unit.
