Program Memory / EEPROM Error
Symptom
Burning smell or visible smoke from the multicooker during operation.
Overheating / Electrical Burning
Symptom
Display and lights flicker or dim when the heater turns on.
Voltage Drop / Weak Power Supply
Symptom
Display segments are missing or unreadable; some digits or icons do not light.
Display Module / Segment Failure
Symptom
Display works but heating is very weak; water takes a very long time to boil or never boils.
Partial Heating Element Failure / High Resistance Connection
Symptom
Excessive steam or water drips from the sides of the lid and down the body during cooking.
Condensation Management / Gasket Overflow
Symptom
Food is consistently undercooked or overcooked compared to selected program settings.

Symptom
Inner pot coating is peeling or scratched, and food sticks or burns easily.
Nonstick Coating Degradation
Symptom
Lid does not close or lock properly; requires excessive force or remains loose.
Lid Hinge / Lock Mechanism Misalignment
Symptom
Multicooker beeps repeatedly and will not start, even though everything appears normal.
Safety Interlock Not Satisfied
Symptom
Multicooker does not power on at all; no lights or display when plugged in.
No Power / Dead Appliance
Symptom
Multicooker heats but never reaches pressure; steam constantly escapes from the lid during pressure programs.
Lid Seal Leakage / Inability to Build Pressure
Symptom
Multicooker makes loud clicking, popping, or metallic banging noises during heating or pressure buildup.
Thermal Expansion / Mechanical Stress Noise
Symptom
Multicooker powers on but buttons or touch panel do not respond, or respond intermittently.
Keypad / Touch Control Failure
Symptom
Multicooker shuts off unexpectedly in the middle of a cooking program without any error code.
Intermittent Power Loss / Thermal Cutoff Trip
Symptom
Steam or hot water sprays forcefully from the steam release valve during pressure cooking, more than usual.
Overpressure Venting / Valve Malfunction
Symptom
Time remaining on the display does not count down correctly; programs finish too early or too late.
Timer / MCU Clock Inaccuracy
Symptom
Unpleasant odor (plastic, chemical, or stale food smell) persists inside the multicooker.
Odor Contamination / Residue Build-up
Symptom
Water or food leaks from the bottom of the multicooker onto the countertop.
