Google • CODE HAL_CAM_ERR_0x302 Pixel 9 Pro High

Pixel 9 Pro Telephoto Freeze

The camera hardware abstraction layer (HAL) encountered a timeout or out-of-range ADC read from the 5x periscope telephoto Optical Image Stabilization (OIS) Hall effect sensor. The camera daemon terminates stream processing to prevent voice coil motor (VCM) driver overload, causing the viewfinder to freeze on 5x zoom switch.

Samsung • CODE SEC_CHG_ERR_04 Galaxy S24 Ultra High

45W Fast Charging Thermal Disconnect

SEC_CHG_ERR_04 is triggered by the Intermediate Frequency Power Management IC (IF-PMIC) or fuel gauge when the sub-board/battery NTC thermistor registers operational temperatures exceeding safety thresholds (typically above 45°C to 50°C) during 45W Super Fast Charging 2.0 (PPS negotiated rail), forcing power rail isolation to prevent thermal runaway.

Rivian • CODE BMS_b018 R1S (Gen 2) Critical

HV Battery Isolation Fault Turtle Mode

The Battery Management System detected high-voltage leakage to vehicle chassis ground below the 500 ohms/volt threshold (typically under 200 kOhms absolute), triggering a safe isolation state and limiting drive power via Turtle Mode to prevent electrocution or pyrotechnic disconnect activation.

LG • CODE LE WashTower Series High

Washer Drum Motor Lock Error

Error code LE indicates a motor lock condition. The main controller detects that the direct-drive brushless DC (BLDC) motor rotor has stalled, the Hall/RPS sensor has failed to report rotation pulses, or an overcurrent state has occurred in the inverter drive.

Shark • CODE 3 Red Blinking Lights FlexStyle Air Styling & Drying System High

3 Red Blinking Lights Overheating

The unit's micro-controller unit (MCU) triggered a thermal protection cutoff due to reading temperatures exceeding safe thresholds (typically >115°C) at the negative temperature coefficient (NTC) thermistor, caused by restricted intake airflow, clogged inlet mesh, or an impaired brushless DC (BLDC) motor.

Shark • CODE Flashing Red Bottom Ring FlexStyle Air Styling & Drying System High

Flashing Red Ring Thermal Cutoff

The unit's micro-controller detected an internal over-temperature condition triggered by the negative temperature coefficient (NTC) thermistor sensing excessive heat build-up. This condition is almost universally caused by an obstructed intake filter restricting brushless motor airflow, causing an automatic thermal shutdown to prevent heating element destruction.

Roborock • CODE Error 44 S8 MaxV Ultra High

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).

FOREO • CODE 5 Rapid Blinks BEAR 2 Medium

Anti-Shock System Conductivity Fault

The FOREO BEAR 2 utilizes an integrated Anti-Shock System that samples skin conductivity across the metallic microcurrent spheres at 200 Hz. Five rapid white LED flashes indicate an out-of-range impedance measurement, open circuit, or excessive surface capacitance, triggering a protection cut-off to prevent galvanic shock.

Ninja • CODE ERR3 Combi All-in-One Multicooker SFP700 High

Steam Boiler Sensor Open Circuit

Error ERR3 trips when the main control board detects an open-circuit state (>1.2MĪ© or 0V return on ADC) across the steam generator NTC thermistor line, disabling combi-steam heating elements to prevent uncontrolled thermal runaway.

Breville • CODE ERR-04 Barista Touch Impress High

Assisted Tamping Motor Over-Torque

The main control board detected an excessive current draw on the 24V DC assisted tamping motor circuit (exceeding safety threshold, typically >1.8A for >300ms), indicating a mechanical jam in the tamping worm drive/rack assembly or an electrical failure in the motor driver circuit.
