Symptom / Description

FAULT

The device does not detect the cart or basket, which prevents a program from starting.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

A problem affects the cart recognition system (sensor, magnet, contactor) or the cart itself is incorrectly positioned.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Check that the cart is correctly inserted and compatible with the device. Clean the detection sensors and check their alignment. Examine the wiring between the sensor and the electronic board.

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
