Possible Causes

Blown internal fuse on control board, Faulty power cord or plug, Failed main control board power supply, Loose neutral or live connection inside base

How to Fix / Troubleshooting

Safety first: Verify the outlet with another appliance first. Unplug the multicooker before opening any covers. If you are not comfortable working with mains voltage, seek professional service.

  • 1. Check outlet and breaker: Confirm the wall outlet has power and that no circuit breaker or GFCI has tripped.
  • 2. Inspect power cord: Look for cuts, kinks, or burn marks. Gently wiggle the cord at the strain relief while watching for flicker (if any lights appear). Replace the cord set if damaged.
  • 3. Access internal fuse (advanced): Remove the bottom cover. Locate the small glass or ceramic fuse on or near the control board. Test for continuity with a multimeter. Replace only with the same rating if blown.
  • 4. Check main connectors: Ensure the power cord leads are firmly attached to the board and that no spade connectors are loose.

If the fuse is intact and there is still no power, the control board’s power supply section is likely failed and the board should be replaced.
