Possible Causes

Stuck or shorted touch keys, Moisture under control panel, Damaged keypad membrane, Loose keypad connector

How to Fix / Troubleshooting

Safety first: Unplug the cooker before working on the control panel.

Initial steps:

  • Drying: If liquid was recently spilled on the panel, unplug the unit and let it dry for 24–48 hours in a warm, dry place. Do not use heat sources that could melt plastic.
  • Clean surface: Wipe the control panel with a slightly damp cloth, then dry thoroughly. Avoid harsh chemicals.

Internal checks:

  • Remove the front panel to access the keypad PCB or membrane.
  • Reseat the keypad connector on the main control board.
  • Inspect for corrosion or residue on the keypad contacts; clean gently with isopropyl alcohol and a soft brush.

Resolution: If specific buttons remain unresponsive or E11 persists, replace the keypad membrane or complete control panel assembly. If a new panel does not resolve the issue, the main control board may be defective.
