Symptom / Description

FAULT

Machine stops mid-cycle, display may flash or be unresponsive.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

Communication error between the main control board (PCB) and the display board.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Disconnect the appliance from power for 10 minutes to reset. Check the wiring harness connecting the two boards for loose connections or damage. If the problem persists, one of the boards may be faulty.

1. Pre-Intervention Electrical Safety Protocols
  • !High-Voltage Safety Protocol: Disconnect 230V power before unplugging edge connectors or removing PCB.
  • !High Voltage DC Warning: Wait at least 5 minutes for SMPS and inverter filter capacitors (up to 380V DC) to discharge safely.
  • !Electrostatic Discharge (ESD): Ground yourself to the metal chassis or wear an antistatic wrist strap before touching circuit tracks.
3. Preliminary Mechanical & Visual Checks
  • Inspect PCB tracks with a magnifying glass for blown triacs, darkened copper tracks, or cold solder joints on power relays.
  • Check electrolytic capacitors for bulging tops or leaked electrolyte residue around pins.
  • Verify edge connector locking clips are intact and pins are free of vibration fretting corrosion.
Perform these diagnostic steps before triggering AI Deep Search or replacing boards.Certified Workshop Routine
