Lid Not Locked / Lock Detection Fault
Symptom
Buttons on the control panel are unresponsive or require very hard presses.
Keypad Membrane Wear / Control Panel Failure
Symptom
Condensation or water collects around the base of the cooker during or after use.
External Condensation / Minor Leak
Symptom
Display flickers, dims, or resets during cooking; sometimes the cooker restarts mid-cycle.
Intermittent Power / Voltage Drop
Symptom
Exterior of the multicooker becomes excessively hot to the touch during normal operation.
Insulation Degradation / Heat Shield Failure
Symptom
Food is burning or sticking heavily to the bottom of the inner pot, especially in rice or sauté modes.
Localized Overheating / Temperature Overshoot
Symptom
Food is undercooked even though the full pressure cooking cycle completes without errors.
Low Actual Pressure / Temperature Calibration Issue
Symptom
Inner pot coating is peeling, scratched, or flaking into food.
Non-Stick Coating Degradation
Symptom
Keep Warm function overheats food, causing it to dry out or burn on the bottom.
Keep Warm Temperature Too High
Symptom
Lid is stuck and will not open after cooking; float valve appears down but lid will not turn.
Mechanical Lid Jam
Symptom
Lid will not close or lock properly; it feels misaligned or stops before the locked position.
Lid Alignment / Hinge or Lock Deformation
Symptom
Multicooker does not power on at all; no lights or display when plugged in.
No Power / Dead Appliance
Symptom
Multicooker emits a strong burning plastic or electrical smell during operation.
Overheating of Internal Components / Electrical Insulation Failure
Symptom
Multicooker heats but never reaches pressure; steam constantly escapes from the lid and cooking takes too long.
Pressure Leak / Inability to Build Pressure
Symptom
Multicooker makes loud clicking, popping, or metallic noises during heating.
Thermal Expansion / Loose Internal Hardware
Symptom
Multicooker powers on but will not start any program; pressing Start does nothing or cancels immediately.
Start Circuit / Keypad Input Failure
Symptom
Multicooker takes excessively long to come to pressure or never reaches the set cooking time.
Extended Preheat / Heat Loss
Symptom
Multicooker vibrates excessively or moves on the countertop during operation.
Excessive Vibration / Unstable Placement
Symptom
Slow cook or yogurt functions do not reach or maintain the correct temperature.
Low-Temperature Control Fault
Symptom
Steam leaking continuously from the float valve area; float never rises fully.
Float Valve Seal Leak
Symptom
Steam or water leaking from around the lid rim during pressure cooking.
Lid Seal Failure / Gasket Compression Loss
Symptom
Steam release valve does not vent properly or is blocked; little or no steam escapes when manually venting.
Blocked Steam Release Valve
Symptom
Unusual metallic or rattling sound when tilting or moving the cooker, even when off.
Loose Internal Component or Debris
Symptom
Water or food appears inside the base of the cooker or seeps out from underneath.
Internal Liquid Ingress
Symptom
Water or starchy liquid spurts out of the steam release valve during pressure cooking.
Foaming / Overfill Causing Liquid Ejection
