Indexed Fault Guides in Kitchen & Culinary
Machine-verified error code diagnostic walkthroughs
Steam Boiler Sensor Open Circuit
Error ERR3 trips when the main control board detects an open-circuit state (>1.2MΩ or 0V return on ADC) across the steam generator NTC thermistor line, disabling combi-steam heating elements to prevent uncontrolled thermal runaway.
E04 Low Water Sensor Lockout
Error E04 triggers when the capacitive or conductimetric water level sensor detects inadequate immersion or an open-circuit state across probe contacts, forcing an immediate heating element cut-off to prevent dry-fire thermal runaway.
Heating Element Thermal Cut Out
Error code E02 designates an open-loop or thermal cut-out event on the primary heating circuit. The microcontroller detects an unexpected drop in element current or an abnormal temperature rate-of-rise divergence, triggering an automatic shutoff via the safety relay to prevent thermal runaway.
Door Lock Sensor Disconnect
The main control board (MCU) has detected an open circuit or signal loss on the door latch microswitch/interlock sensing loop during pre-heat or operation, triggering a safety shutoff accompanied by rapid audible beeping.
ERR2 Lid Latch Sensor Fault
The main control board detected an open circuit or state mismatch from the Combi Cooker lid/door interlock microswitches during high-heat or pressurized steam operations, triggering an ERR2 safety shutdown.
ERR3 Door Interlock Sensor Failure
Error ERR3 trips when the main control board detects an open or erratic signal across the door interlock safety microswitch circuit during pressurized steam or combi cooking modes, halting operation to prevent steam burns.
Thermal Runaway Element Cutout Fault
Error E05 indicates an uncommanded cavity overtemperature condition or a discrepancy between heating element state and temperature sensor feedback. The control board has tripped safety element cutouts to prevent catastrophic thermal runaway.
Low Water Dry Run Fault
Error E04 triggers when the liquid level falls below the optical/conductive water level threshold or when scale deposits insulate the probe, tripping firmware dry-run protection to prevent heater burnout.
Lid Position Switch Failure
Error ERR2 indicates an open circuit or logic mismatch in the SmartLid interlock safety detection system. The main control board (PCB) cannot detect valid 5V DC return signals from the microswitches monitoring door closure and the Combi Cooker/Air Fry mode slider position.
Heating Element Open Circuit
Error E01 triggers when the main control board detects an open loop or infinite resistance across the primary heating element circuit during the initial pre-check or heating cycle, indicating a blown thermal fuse, fractured element, or disconnected wiring.
Ninja Combi SHUT Error Fix
The main control board detected an open circuit across the door safety interlock switches while a cooking cycle was initiated. As a safety lockout, heating elements and convection fans are disabled until door closure continuity is verified.
Persistent Hood Microswitch Failure
The main control board detects an open interlock circuit despite the lid being fully lowered. Cooking operations are inhibited due to safety firmware flagging an unclosed hood microswitch or a high-resistance contact path.
Heating Element NTC Open Circuit
Error ERR 02 indicates that the main control board has detected an open circuit or infinite resistance across the lower/main heating element NTC thermistor circuit, tripping thermal runaway protection and disabling all heating cycles.
Motor Cannot Reach Set Speed
Error C140 indicates that the brushless DC (BLDC) reluctance motor controller detected a velocity deviation fault where actual RPM failed to reach or maintain the commanded setpoint under current drive limits, tripping overcurrent/stall safety protection.
Motor Hall Sensor Imbalance
Error C140 triggers when the Motor Control Unit (MCU) detects an asymmetrical pulse train or phase discrepancy among the three Hall effect sensors on the brushless DC (BLDC) motor assembly. The microcontroller locks drive output to prevent stall conditions and thermal runaway.
Ice Fan Motor Failure Er IF
The main PCB failed to detect a feedback pulse signal (FG tachometer reading) from the ice maker compartment blower fan motor (BLDC) within 65-115 seconds of commanded operation, tripping the Er IF protection lock.
Error C140 Motor Speed & Blade Overload Lockout Fix
Thermomix TM6 displays Error C140 or C142 on touchscreen: "Motor speed cannot be reached. Please check the mixing knife." This error trips the reluctance motor controller when dough resistance exceeds torque limits, or when food particles or worn seal rings cause friction between knife drive pins and the motor coupling socket.
