E4
E4 error appears when trying to start a pressure-cooking program; unit may not build pressure.
Lid Temperature Sensor Fault / Overtemperature at Lid
E5
E5 error appears during pressure cooking; unit stops heating and may release steam.
Pressure Sensor Fault / Overpressure Detection
E6
E6 error appears immediately when selecting a program; cooker does not attempt to heat.
Internal Communication / Control Board Fault
E7
E7 error appears during preheat; cooker may partially warm but never reaches pressure or target temperature.
Heating Circuit Fault – Insufficient Heating
E8
E8 error appears and cooker stops; often associated with very high internal temperature or dry pot.
Dry-Boil / Extreme Overheat Protection
E9
E9 error appears randomly during operation; cooker may shut down unexpectedly.
AC Input / Power Supply Fault
Err
Display shows a generic “Err” or “Error” message and beeps; no specific numeric code is given.
Generic Control System Error
LID
Display shows a lid-related error (e.g., “LID”, “Lid” or flashing lid icon) and the cooker will not start a pressure program.
Lid Lock / Lid Position Switch Not Engaged
Symptom
Burning smell or visible smoke from the multicooker during use.
Overheating / Electrical Burn
Symptom
Buttons on the control panel do not respond or respond intermittently.
Keypad / Button Failure
Symptom
Display and lights flicker or reset during cooking; unit may restart mid-cycle.
Intermittent Power / Voltage Drop
Symptom
Display is dim, segments missing, or completely blank while the unit still heats.
Display Module Failure
Symptom
Exterior of the multicooker becomes excessively hot to the touch during operation.
Insulation / Thermal Shielding Failure
Symptom
Food is consistently overcooked or scorched on the bottom while the top remains undercooked.
Uneven Heating / Temperature Overshoot
Symptom
Food is consistently undercooked even when using recommended times and settings.
Low Temperature / Underheating
Symptom
High-pitched squealing or buzzing noise from the base during operation.
Electrical Vibration / Coil Whine
Symptom
Inner pot coating is peeling or scratched; food sticks badly and may show dark flakes.
Nonstick Coating Degradation
Symptom
Inner pot is not detected; some programs are disabled or the cooker shows a pot icon warning.
Inner Pot Presence Detection Failure
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 and pressure seems released.
Lid Mechanism Jammed
Symptom
Loud hissing from the steam release valve throughout the entire pressure cooking cycle; food seems undercooked.
Steam Release Valve Not Sealing
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 area.
Pressure Not Building / Steam Leakage
Symptom
Multicooker makes loud clicking, popping, or metallic banging noises during heating or pressure cooking.
Thermal Expansion / Mechanical Stress Noise
Symptom
Multicooker powers on but will not start any program; pressing Start does nothing or cancels immediately.
Start Circuit / Safety Interlock Not Satisfied
Symptom
Multicooker takes an unusually long time to come up to pressure.
Slow Pressure Build
Symptom
Rattling noise from inside the lid when shaking it gently; performance may be unaffected.
Loose Lid Components
Symptom
Steam or water leaks from around the lid handle or top of the lid during pressure cooking.
Lid Vent Blockage / Gasket Misfit
Symptom
Strong metallic or plastic odor from the multicooker during use, persisting after several cycles.
Odor Contamination / Material Off-Gassing
Symptom
Timer counts down but the cooker does not heat; food remains cold.
Heating Circuit Open / Relay Not Engaging
Symptom
Unit beeps repeatedly and cancels cooking when the countertop is bumped or the unit is moved slightly.
Vibration-Sensitive Safety Interlock / Loose Connections
Symptom
Unit trips the household circuit breaker or RCD when plugged in or when heating starts.
Electrical Short / Ground Fault
Symptom
Water or starchy liquid drips down the sides of the multicooker during or after cooking.
Condensation Management / Overflow
