3 Codes

CODE 03 Severity: High Difficulty: Intermediate

Steam Boiler NTC Sensor Fault

Error 03 indicates that the control logic detected an open or short circuit on the dedicated steam boiler NTC thermistor, or an out-of-range temperature reading preventing safe heating regulation.

CODE ER03 Severity: Critical Difficulty: Advanced

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.

CODE ERR03 Severity: High Difficulty: Intermediate

Steam Boiler Heating Timeout

Error ERR03 indicates a steam boiler thermal sensor timeout where the NTC temperature sensor fails to register a target temperature rise within the MCU's programmed window (typically 20 minutes from boot). This failsafe activates to prevent thermal runaway caused by an open thermal fuse, failed heating element, defective NTC thermistor, or triac switching failure on the power PCB.
