Display Module or Backlight Degradation
Symptom
Fan runs loudly or does not run at all on models with a cooling fan.
Cooling Fan Failure
Symptom
Keep Warm function overheats food, causing it to dry out or burn.
Keep Warm Temperature Control Fault
Symptom
Metallic or rattling noise from inside the lid when opening or closing.
Loose Lid Components
Symptom

Mechanical Vibration / Imbalance
Symptom
Persistent electrical or plastic burning smell from the base, even without visible residue on the plate.
Overheating Electrical Components
Symptom
Programs end too early; rice or other foods are undercooked even though the cycle completes.
Incorrect Temperature or Pressure Sensing (Premature Cycle Termination)
Symptom
Steam constantly escapes from the steam release valve even when set to sealing; pressure does not build.
Steam Release Valve Not Sealing
Symptom
Steam or water leaks from around the lid during pressure cooking; the cooker struggles to reach or maintain pressure.
Lid Seal Leakage
Symptom
Strong burning smell during cooking, sometimes without visible smoke.
Residue Burning on Heating Plate or Inner Pot Exterior

Symptom
The multicooker powers on but does not heat; programs run but food remains raw.
Main Heating Element Failure
Symptom
The multicooker trips the household circuit breaker or RCD when plugged in or when heating starts.
Electrical Short or Ground Fault
Symptom
The outer body of the multicooker becomes excessively hot to touch during operation.
Insulation or Thermal Shielding Degradation
Symptom
Unusual loud clicking, popping, or buzzing noise from the base during heating.
Abnormal Electrical or Mechanical Noise
Symptom
Water or condensation drips from the side or bottom of the multicooker during or after cooking.
