Possible Causes

Loose internal screws or panels, Vibrating heating plate, Noisy relay on PCB, Fan (if fitted) hitting obstruction

How to Fix / Troubleshooting

Safety first: Unplug the cooker before opening any covers.

  • Check placement: Ensure the cooker is on a stable, level surface and not touching other objects that can resonate.
  • Inspect inner pot and lid: Remove and reseat the pot and lid to rule out rattling accessories.
  • Internal check (advanced): Open the base and tighten any loose screws on the heating plate, frame, or PCB mounts. Ensure any internal fan spins freely without hitting wires.
  • Relay noise: Occasional soft clicks are normal, but loud buzzing from a relay indicates a failing component and the PCB should be replaced.
