How to Fix / Troubleshooting
Safety first: Unplug the multicooker before opening any covers.
- Power cycle: Unplug the unit for at least 10 minutes to allow the control board to fully discharge. Plug back in and test.
- Check for stuck buttons: Press each button on the control panel several times. If any button feels stuck or does not click, clean around it with a soft, dry cloth.
- Inspect keypad cable (advanced): Remove the front or top panel to access the keypad ribbon cable. Ensure it is fully inserted into the connector on the control board.
- Environment: Avoid operating the cooker in very humid environments where condensation can affect the keypad.
