Possible Causes

Partially failed heating element with increased resistance, Excessive scale or residue on heating plate, Poor contact between inner pot and heating plate

How to Fix / Troubleshooting

Safety first: Unplug and cool before cleaning or inspection.

  • Clean contact surfaces: Remove the inner pot and clean both the pot bottom and heating plate with a soft cloth. Remove any burnt-on residue.
  • Check inner pot flatness: Ensure the pot bottom is flat and not domed. Replace if warped.
  • Measure heating element resistance: With the base cover removed and the unit unplugged, measure the element resistance. A significantly higher reading than specified can indicate a weakening element.
  • Use warm water: Starting with warm tap water can reduce preheat time and help determine if the heater is underperforming.

If heating remains slow despite clean surfaces and a good pot, the heating plate assembly or control board may need replacement.
