Abnormal Pressure Drop / Lid Open During Cooking
Symptom
Buttons on the control panel are unresponsive or require very hard presses; some functions cannot be selected.
Keypad / Touch Panel Failure
Symptom
Condensation accumulates on the control panel or drips down the front of the cooker.
Condensation Management / Steam Deflector Issue
Symptom
Display and lights flicker or reset when the heater turns on; cooker may restart mid-cycle.
Power Instability / Brownout Inside Unit
Symptom
Display is very dim, segments missing, or completely blank while the cooker still heats.
Display Module / Backlight Failure
Symptom
Excessive steam or water drips from the steam vent and lid during normal cooking; kitchen becomes very steamy.
Abnormal Steam Release / Venting Issue
Symptom
Food is consistently undercooked or overcooked compared to the selected Toshiba program (e.g., rice too hard or too soft).
Temperature/Pressure Calibration Drift
Symptom
Inner lid plate or gasket shows signs of rust, discoloration, or deterioration.
Corrosion / Material Wear in Lid Assembly
Symptom
Inner pot bottom has burnt or scorched food while the top remains undercooked; food sticks badly.
Localized Overheating / Poor Heat Distribution
Symptom
Inner pot wobbles excessively or does not sit level; scraping noise when stirring.
Inner Pot Support / Heater Plate Deformation
Symptom
Keep-warm function turns off too soon or does not maintain food at a safe hot temperature.
Keep-Warm Control / Sensor Drift
Symptom
Lid does not close or lock properly; requires excessive force or remains loose.
Lid Hinge / Lock Mechanism Misalignment
Symptom
Multicooker does not power on at all; no lights or display when plugged in.
No Power / Dead Appliance
Symptom
Multicooker heats but does not build pressure; steam constantly escapes from the lid area.
Pressure Leak / Inability to Seal
Symptom

Start Circuit / Safety Interlock Not Satisfied
Symptom
Multicooker trips the household circuit breaker or RCD when plugged in or when heating starts.
Short Circuit / Ground Fault
Symptom
Persistent unpleasant odor (plastic, chemical, or rancid smell) from the multicooker even after cleaning.
Odor Contamination / Material Degradation
Symptom
Programs end too quickly; cooker beeps and switches to keep-warm after only a few minutes without fully cooking food.
Premature Program Termination
Symptom
Rattling or vibration noises from the lid area when steam is released or during pressure cooking.
Lid Assembly Vibration / Loose Components
Symptom
Steam or hot water spurts from around the float valve area during pressure buildup.
Float Valve Seal Failure
Symptom
Strong burning smell or visible smoke from the multicooker during operation.
Overheating / Electrical Burning
Symptom
Unusual loud clicking, popping, or buzzing noises from the multicooker during heating.
