Symptom / Description

FAULT

A temperature alarm sounds, indicating an anomaly in zone 3 of the wine cellar.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The actual temperature of zone 3 deviates from the programmed value. This may be due to external factors (door, ambient temperature) or an internal fault in the refrigeration circuit.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Check that the door to zone 3 is securely closed and that nothing is obstructing its closing. 2. Make sure the device is properly ventilated and not exposed to a direct heat source. 3. Wait a few hours to see if the temperature regulates. 4. A persistent alarm indicates the need for technical diagnostics to identify a possible component failure.

1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Disconnect 230V mains power before releasing door gasket clamp or lock retaining screws.
  • !Never short-circuit or bypass the safety door lock contacts: severe hazard of rotating drum exposure or fire.
  • !Keep fingers away from spring-loaded latch mechanisms during closure cycling.
3. Preliminary Mechanical & Visual Checks
  • Inspect door strike pin and handle latch hook for plastic deformation, breakage, or misalignment.
  • Check door hinge alignment: a sagging door prevents the latch tongue from engaging the safety microswitch.
  • Locate and verify emergency manual pull cord inside the lower drain pump hatch.
Perform these diagnostic steps before triggering AI Deep Search or replacing boards.Certified Workshop Routine
