What happened?

The printer displays the message: "Enclosure fan not spinning. Check it for possible debris, then inspect the wiring."

This warning indicates that the enclosure filtration fan, part of the Advanced Filtration System on the XL enclosure, fails to spin. 

Error name: Enclosure fan error

Error code: #17830 (XL)

How to fix it?

Start by inspecting the fan for mechanical blockage or electrical issues:

• Turn off the printer and unplug it from power.
• Locate the enclosure filtration fan on the rear of the XL Enclosure.
  
• Access the filtration fan by loosening 4x M4x5r screws to release the cover. 
  
• Temporarily remove the HEPA filter. This will give some space 
  
• Check for debris: Look for dust, filament scraps, or anything obstructing the fan blades.
• Spin the fan blades manually: They should move freely without resistance or noise.
• Inspect the wiring: Make sure the fan connector is fully seated and the wires are undamaged and not pinched.
  

  

Testing after inspection:

• Reassemble the components, and power the printer on.
• Navigate to LCD Menu -> Control -> Enclosure settings -> Enclosure, and switch it off and then on again, to trigger an automatic enclosure fan test. 

If the fan still does not spin or the warning returns:

• Replacement may be required. Refer to the Advanced Filtration System installation guide.
• Contact our technical support in case the issue persists.
