Machine-verified error code diagnostic walkthroughs
MopExtend Swing Arm Track Obstruction
Error 11 indicates the right-side MopExtend robotic swing arm encountered mechanical resistance or an overcurrent condition on its actuator drive motor. The MCU halts mop extension to prevent servo gear stripping or motor driver burnout.
Side Brush Extend Arm Blocked
Error Code 18 triggers when the mainboard motor driver detects an overcurrent condition or missing limit feedback on the robotic side brush extension swing-arm actuator during deployment or retraction cycles.
Dirty Water Tank Sensor Fault
Error 102 trips when the base station microcontroller detects a continuous dirty water tank overflow condition, an open or shorted float sensor circuit, or failure to evacuate wastewater from the washboard tray during the mop cleaning cycle.
VibraRise Lift Motor Stall
The mainboard detected an overcurrent event or a missing Hall sensor feedback pulse from the VibraRise mop lifting actuator. When the DC lift motor attempts to raise or lower the sonic mopping plate, excessive mechanical resistance or an electrical open circuit trips motor driver overcurrent protection (Error 44).
Base Station Heating Module Fault
Fault 108 is triggered when the base station power management MCU detects an open circuit, short circuit, or thermal runaway condition in the mop-washing PTC/instant heating module, preventing 70°C water sanitization.
LDS Turret Blocked Error 1
Error 1 indicates that the Light Detection and Ranging (LDS) sensor module cannot rotate freely or optical return signals are obstructed. The mainboard optical encoder detects low/zero RPM or stalls, triggering motor drive cut-off protection to prevent driver burnout.
Side Brush Robotic Arm Jam
Fault 18 triggers when the main control board detects an overcurrent condition (>450mA) or a lack of position encoder feedback from the robotic side-brush extension servomotor, indicating mechanical binding or actuator stall.
Mop Lift Position Sensor Error
Fault 19 indicates a telemetry mismatch in the mop assembly's lifting and auto-detaching mechanism. The mainboard detects that the Hall effect sensors or optical limit switches failed to confirm the expected physical travel limit within the motor drive cycle duration, engaging motor stall overcurrent protection.
VibraRise Mop Mechanism Jammed
Error 44 triggers when the motor driver detects persistent overcurrent (stall condition exceeding threshold current >1.2A for 2+ seconds) or Hall-effect position sensor timeout while attempting to actuate the VibraRise 3.0 mop lifting carriage.
MopExtend Arm Motor Fault
Error 107 indicates the mainboard micro-controller detected an abnormal current draw, stall condition, or lack of hall sensor feedback from the MopExtend robotic arm servo/stepper actuator during lateral extension or retraction cycles.
LiDAR Turret Rotation Failure
Error 11 triggers when the LDS (Laser Distance Sensor) optical encoder fails to register RPM feedback within the expected 300 RPM (5 Hz) window. The mainboard halts navigation due to stalled turret rotation, broken drive belt, seized motor bearings, or optic path obstruction.
LDS Sensor Jammed or Obstructed
The Laser Distance Sensor (LDS) turret failed to spin or the optical triangulation receiver timed out during initialization. The MCU monitors the LDS motor's optical encoder/hall-feedback RPM and current draw; if the turret does not reach approximately 300 RPM (5 Hz) within 3 seconds, a stall protection fault is asserted.
VibraRise Mop Actuator Jammed
Error 10 triggers when the robot controller detects an overcurrent trip or stroke timeout on the VibraRise mop carriage lift actuator circuit. When transitioning between hard surfaces and carpet, the microcontroller energizes the mop lift motor via an H-bridge driver while polling limit switches or optical position interrupters. If current exceeds safe operational limits (typically >450mA peak) or if stroke limits fail to transition within 3.5 seconds due to mechanical binding, broken gearing, or sensor misalignment, the robot halts to prevent motor thermal runaway.
Mop Lifting Motor Stalled
Error 12 triggers when the mainboard microcontroller detects an overcurrent state on the mop elevation actuator driver or fails to register a state change from the upper/lower limit microswitches within the expected 1500ms timeout window.
MopExtend Arm Limit Switch Stall
Error 107 occurs when the robot's MCU detects an actuation timeout, current spike, or failure of the optical/microswitch sensor during the MopExtend arm's outward cycle along baseboards. The motor controller cuts drive current to protect the servo assembly from thermal burnout.
Side Brush Arm Extension Blocked
Dreame X40 Ultra Error 12 triggers when the mainboard motor driver circuit detects an overcurrent condition (stall current exceeding threshold) or positional timeout on the SideReach extendable side brush robotic arm actuator. This occurs when the articulating scissor/linkage mechanism is physically jammed by debris, foreign hair binding the arm pivot, or mechanical gear stripping in the extension drive box.
FlexiArm Side Brush Motor Stall
The mainboard micro-controller detected excessive current draw on the FlexiArm actuation servo or rotary motor driver circuit (overcurrent threshold exceeded), indicating mechanical binding, debris obstruction, or gear train failure.
FlexiArm Side Brush Motor Jam
Error 42 indicates that the dynamic FlexiArm deployment actuator encountered excessive mechanical resistance or an overcurrent condition (>350mA) while attempting to extend or retract the robotic side brush mechanism.
FlexiArm Side Brush Stall
Error 10 indicates an overcurrent or stall condition detected on the side brush motor or its robotic FlexiArm extension linkage. The mainboard current-sensing shunt resistor detects motor current exceeding threshold (>650mA sustained) or a failure in the dynamic arm deployment limit switch, triggering an automatic protective shutdown.
Side Brush Extension Arm Stuck
Error 108 triggers when the mainboard detects an overcurrent condition (>450mA) or a hall-effect sensor timeout on the motorized side brush extension linkage, indicating mechanical binding or actuator stall.
FlexiArm Side Brush Stall
Error 42 indicates an overcurrent or stall condition detected by the mainboard current-sensing shunt resistor on the FlexiArm dynamic extension side brush motor driver circuit, caused by foreign matter wrapping, gear train binding, or actuator obstruction.
Extending Side Arm Motor Fault
Error 21 indicates an overcurrent or stall condition detected on the robotic side-arm linear actuator/swing motor driver circuit. The microcontroller tripped overcurrent protection due to mechanical obstruction, gear train seizure, or sensor feedback failure.
VibraRise Lift Motor Stall
Error 44 indicates an overcurrent or stall condition detected by the mainboard current-sense shunt on the VibraRise mop lifting motor. The H-bridge driver tripped overcurrent protection due to mechanical obstruction, gear binding, or motor winding failure.
Extendable Side Arm Jammed
The mainboard detected an overcurrent trip or mechanical stall on the side brush extension servomotor/leadscrew mechanism. Hall-effect limit switches failed to register arm travel within expected timing thresholds.
FlexiArm Side Brush Motor Stall
Error 104 indicates an overcurrent or stall condition detected on the Roborock FlexiArm mechanical deployment linkage or rotational side brush DC drive motor. Mainboard current-sensing shunts trigger shutdown when load exceeds safety thresholds.
Main Brush Roller Stall Overcurrent
Main drive MCU detected current draw exceeding the 1.8A safe operating threshold on the DuoRoller drive motor circuit, triggering firmware-level overcurrent protection to prevent motor winding burnout and driver IC damage.
FlexiArm Side Brush Jammed
The main PCB detected an overcurrent event or mechanical stall condition on the FlexiArm servo extension actuator or the primary side brush motor circuit, triggering an automatic protective shutdown.
Side Brush Arm Gear Stall
The robotic arm actuator's micro-stepper/DC servo driver detected overcurrent (>350mA) or limit micro-switch timeout during side brush reach extension or retraction, tripping the stall protection circuit.
Suction Fan Motor Stall
The mainboard firmware detected an abnormal current spike or a missing Hall-sensor tachometer feedback signal from the brushless DC (BLDC) suction turbine fan assembly, triggering an overcurrent safety cutoff to prevent motor driver IC failure.
FlexiArm Side Brush Stuck Retracted
Error 105 indicates the robotic arm deployment mechanism failed to extend from its housing. The MCU detected motor overcurrent (>350mA) or an endstop optical/Hall sensor timeout during the extension sequence.
FlexiArm Side Brush Stuck
Error 107 triggers when the FlexiArm micro-stepper motor or mechanical linkage encounters excessive resistance during side brush extension or retraction. The MCU detects overcurrent on the extension drive circuit or a limit switch timeout, shutting down the arm actuator to prevent motor burnout.
VibraRise Mop Mechanism Stuck
Error 23 triggers when the mainboard micro-controller detects motor overcurrent or timeout via optical/hall-effect limit switches during mop module retraction or deployment cycles.
FlexiArm Side Brush Jammed
Error 51 is triggered when the microcontroller detects a positional stall, travel timeout, or current spike on the FlexiArm side brush extension actuator. This occurs when foreign matter wedges the articulating linkage, the micro-worm drive binds, or the actuator position limit switch fails to signal state transition.
VibraRise Mop Motor Jammed
Error 28 indicates that the mainboard MCU detected an overcurrent stall condition or a positional timeout on the VibraRise mop lifting mechanism. The motor controller attempts to raise or lower the mop module, but mechanical binding or failure of the position-sensing limit switch prevents completion within the 3.0-second actuation window.
Error 10: Dock Auto-Empty Air Duct Blocked / Filter Jammed
Error 10 is generated when the vacuum attempts to evacuate debris at the RockDock Ultra dock, but the differential pressure sensor detects an air blockage or suction motor overload exceeding the 27,000 Pa vacuum threshold.
