Symptom / Description

FAULT

Cooking zone 3 does not respond to selection, does not maintain temperature, or the cooking assistant does not activate for this zone.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

A malfunction is detected in the selection touch sensor, the keep warm sensor (Hold) or the cooking assistant circuit for cooking zone number 3.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Unplug the cooktop from the power supply for 5 minutes to reset it. 2. Plug the unit back in and retest zone 3. 3. If the error persists, clean the glass surface above the controls with a soft, dry cloth. 4. If the problem is not resolved, service is required to inspect and potentially replace the touch control module.

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.
