Solutions

Diagnóstico rápido

This code appears if the lid is not fully engaged or if a bit of label debris is blocking the cover latch from seating correctly.

Solución paso a paso

  1. Re-close: Open the cover entirely, verify no obstructions exist, and close until it clicks.
  2. Debris Removal: Clean the latch and sensor area of any label backing paper or adhesive.
  3. Sensor Cleaning: Use a swab to remove dust from the proximity sensor.

Prevención y mantenimiento

Avoid slamming the cover. Regular cleaning of the internal compartment prevents sticky residue from reaching the sensors.

Cuándo llamar a un técnico

If the latch clicks into place but the error remains, the internal switch has likely failed and requires service.
