Possible Causes

How to Fix / Troubleshooting

Safety first: Unplug the cooker before inspecting the cord or inlet.

  • Check cord fit: Ensure the power cord is fully inserted into both the wall outlet and the cooker inlet. Wiggle gently to see if the display flickers (do this only when cool and with caution).
  • Try another outlet: Plug the cooker directly into a different wall outlet without an extension cord.
  • Inspect cord and inlet: Look for burn marks, looseness, or damage at the inlet. Replace the cord if any damage is found.
  • Avoid overloading circuit: Do not run multiple high-wattage appliances on the same circuit as the multicooker.

If flickering continues with a good cord and outlet, the internal power supply on the PCB may be failing and should be serviced.
