#901 Door Open / Start-up Test Failed / Door Detection Problem

Step 1 - Remove the module

Determine your result and the next action to take:

Step 3 - Check the door sensor

Step 4 - Check the sensor's location

Remove the external magnets in Step 3 and gently press the sensing area in an oval shape.

Make sure that the glue only goes to the sides of the oval sensor.

Determine your result and the next action to take:

Step 5 - Check the position of the door cover

Poor detection of the door may be led by the position of the door being misplaced as the magnets are mounted on the cover.
(The position of the grooves on the cover and the frame should be aligned.)

If your door cover is misplaced like the photo below, it could be because of the frame being bent or damaged. 

Determine your result and the next action to take:

Step 6 -Exclude the possibility of firmware issues

An unsuccessful firmware installation might cause the detection to be unstable, and resetting to factory settings can eliminate the possibility of firmware issues effectively.

• First, reset to factory (Main Page > Machine > Settings > Reset to Factory > Yes)
  
  
  
• After factory reset, follow the steps in the link on How to update the machine firmware and ensure it is updated to the latest version.
  
  
• After the update, enter control mode and see if the door icon works normally (Refer to Step 3)
