Thermal Cut-Off Ring Blinking
The unit's onboard microcontroller has initiated an emergency shutdown due to an over-temperature state. An internal NTC thermistor reading exceeded the safety threshold (typically >115°C at the heater core), or the thermal bimetallic fuse open-circuited due to choked airflow or BLDC motor stall.
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.
HV Isolation Degraded BMS_a035
The Battery Management System (BMS) detected that electrical isolation resistance between the 400V/800V high-voltage DC bus and the low-voltage 12V chassis ground dropped below the standard threshold (typically <500 ohms/volt or <100 kΩ total). This safety interlock prevents potential electric shock or thermal events by inhibiting DC fast charging and vehicle drive readiness.
VCI Bluetooth Drops Error 02
Error 02 indicates a persistent packet drop or baud-rate desynchronization between the MaxiVCI V200 interface and the tablet's Bluetooth baseband processor, typically induced by vehicle DLC bus contention, low battery terminal voltage (<11.8V), or corrupted VCI transceiver firmware.
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.
30W Turbo Black Screen Reboot
Under peak 30W Turbo charging loads (sustained SPL/sPPT/fPPT up to 53W boost), the AMD Ryzen Z1 Extreme APU crosses the 95°C critical junction threshold (TjMax) or causes VRM over-temperature protection (OTP) on the DrMOS power stages, triggering an immediate black screen cut-off and kernel power reboot.
Steam Boiler Thermal Overheat Failure
Error ER03 indicates a steam boiler over-temperature or NTC sensor fault on the Breville Oracle Touch. The main controller halts operation and triggers an audible continuous alarm when the steam boiler NTC temperature probe reports out-of-range resistance (open/short circuit) or the thermal fuse/triac circuit detects uncontrolled thermal runaway.
Remote Controller Communication Fault
Error code H76 designates a bidirectional serial communication failure between the indoor control board and the remote controller (RC/display interface). When communication is lost for more than 60 consecutive seconds, the outdoor unit is forced into an operational lockout to prevent unmonitored compressor cycling.
Direct Drive Motor Locked LE
Error code LE indicates a Locked Motor (Drive Error). The main PCB inverter controller detects that the Direct Drive brushless DC (BLDC) motor rotor is stalled, failing to achieve target RPM, or the Hall-effect rotor position sensor (RPS) feedback signals are missing or erratic.
Right TrueStrike Mouse Drift Disconnect
The right TrueStrike controller's base-mounted optical tracking sensor (PixArt low-power optical navigation IC) experiences intermittent I2C/SPI bus drops or false differential tracking reports. This is triggered by mechanical switch misalignment in FPS mode, loose ribbon cable seating at the daughterboard, or particulate contamination on the internal optical aperture.
