Control Panel / Keypad Failure
Symptom
Excessive vibration or rattling noise during pressure or slow cooking (not spin-related).
Mechanical Vibration / Loose Internal Components
Symptom
Food is consistently undercooked or overcooked compared to recipe times.
Temperature / Pressure Calibration Drift
Symptom
Inner lid (removable plate) is difficult to remove or reinstall.
Inner Lid Retainer / Clip Deformation
Symptom
Inner pot rocks, rattles, or does not sit flat on the heating plate.
Poor Pot-to-Heater Contact / Warped Inner Pot
Symptom
Keep Warm function does not maintain temperature; food cools down too quickly.
Low-Power Heating Control Fault
Symptom

Stuck Float Valve / Residual Pressure
Symptom
Multicooker does not power on at all; no lights or display when plugged in.
No Power / Dead Unit
Symptom
Multicooker heats but never reaches pressure; steam constantly escapes from the lid area.
