#901 Door Opened/Door Issue/Door cover can’t be closed

FLUX Support Team
  • Updated

Description:

The #901 Door Opened error pops up during a task when the system detects the door being opened.
The symptom is usually that the system is unable to detect a door close signal, meaning the door icon cannot be changed to 'closed'. Another symptom is that the error appears randomly during tasks, even when the door is closed securely.

Regardless of the symptom you experience with your machine, please follow the steps below in order.

Possible Causes

  1. The system fails (Re-update the firmware or reflash RK board.)
  2. The sensing object (metal piece) for the door sensor is off the position.
  3. The mainboard/MB/motherboard is malfunctioning and fails to capture the signal.
  4. The door sensor itself is malfunctioning.
  5. The door sensor cable/wire is malfunctioning.

Step 1

Re-update the firmware to a stable version to first rule out the possibility of a firmware issue.
