C1
C1 or calibration error appears; cooker may not regulate temperature correctly.
Temperature Sensor Calibration Error
E1
Multicooker beeps and displays E1 shortly after start; heating does not begin or stops immediately.
Bottom Temperature Sensor (NTC) Open or Short Circuit
E2
Display shows E2 and the cooker will not start or stops heating; often appears when trying high-temperature or pressure programs.
Lid / Upper Temperature Sensor Fault
E3
E3 appears during cooking; unit stops heating and may beep continuously.
Overtemperature / Dry-Boil Protection Triggered
E4
E4 error appears, often when using pressure or high-heat modes; cooker may not pressurize or may shut down early.
Overpressure / Pressure Sensor Fault
E5
E5 error appears and the cooker refuses to start pressure programs; sometimes accompanied by a clicking sound from the relay.
Overcurrent / Heating Circuit Protection
E6
E6 error on display; cooker may start but quickly stops, or refuses to enter certain modes.
Communication / Internal Sensor Calibration Error
E7
E7 error appears when trying to start a program; lid seems closed but cooker will not begin.
Lid Lock / Lid Position Switch Fault
E8
E8 error appears, often accompanied by failure to build pressure or premature end of cooking.
Pressure Not Reached / Leak Detected
E9
E9 error appears and the cooker stops; may be associated with very high pressure or steam escaping from safety valve.
Serious Overpressure / Safety System Triggered
Err
Display shows 'Err' or 'Error' and beeps; no specific numeric code; cooker will not start.

H1
H1 or 'Hot' error appears; cooker refuses to start a new program immediately after finishing one.
Excessive Internal Temperature Before Start
H2
H2 error appears and cooker stops; often during sauté or fry modes.
Overheat Protection / Thermal Fuse Triggered
Lid
Display shows 'Lid' or a lid icon; cooker refuses to start or build pressure.
Lid Not Detected / Lid Sensor Open
P1
P1 error or code appears and cooker stops heating; often associated with low or no pressure.
Pressure Sensor Low Signal / No Pressure Detected
P2
P2 error appears during cooking; cooker may overheat or shut down unexpectedly.
Pressure Sensor High Signal / Overpressure Detected
U1
U1 or low-voltage error appears; cooker may reset or not heat properly.
Input Voltage Too Low / Power Supply Instability
U2
U2 or over-voltage error appears; cooker may shut down to protect electronics.
Input Voltage Too High
Symptom
Beeping continues and cooker will not start; display may show a child lock icon.
Child Lock Activated
Symptom
Burnt smell during operation; visible scorching on the bottom of the inner pot.
Food Scorching / Localized Overheating
Symptom
Buttons or touch controls respond intermittently or activate by themselves.
Keypad / Touch Sensor Malfunction
Symptom
Display is very dim or flickers; cooker may still function but is hard to read.
Display Backlight / Power Supply Degradation
Symptom
Excessive vibration or movement of the cooker on the countertop during operation.
Mechanical Imbalance / Footing Issue
Symptom
Inner lid or underside of the lid accumulates a lot of food residue and is difficult to clean; odors persist.
Inner Lid Seal / Anti-Splash Design Issue
Symptom
Inner pot is difficult to remove; it sticks to the heating plate after cooking.
Pot Warping / Thermal Expansion Binding
Symptom
Keep Warm function does not maintain temperature; food becomes cold or continues to cook vigorously.
Keep Warm Temperature Control Fault
Symptom
Loud hissing from the safety valve or top of the lid during cooking; cooker may not reach full pressure.
Safety Valve Venting / Overpressure Bypass
Symptom
Multicooker builds no pressure; steam constantly escapes from the lid area.
Pressure Seal Failure
Symptom
Multicooker does not power on at all; no lights or display when plugged in.
No Power / Dead Appliance
Symptom
Multicooker heats very slowly or never reaches the set temperature; food remains undercooked.
Weak Heating / Partial Heating Element Failure
Symptom
Multicooker overheats; food burns on the bottom even on low settings.
Temperature Regulation Failure
Symptom
Multicooker powers on but will not start any program; pressing Start does nothing.
Control Panel Input Failure
Symptom
Steam or water leaks from around the lid hinge or side of the lid during pressure cooking.
Lid Deformation or Hinge Misalignment
Symptom
Strong plastic or burnt electronics smell from the cooker, even when new or lightly used.
Overheating of Internal Plastic or PCB Components
Symptom
Timer or delayed start does not work correctly; cooker starts immediately or not at all.
Timer / Clock Function Fault
Symptom
Unusual rattling, buzzing, or clicking noises from inside the cooker during operation.
Mechanical Vibration or Loose Component
Symptom
Water or condensation drips down the sides of the cooker during or after cooking.
