E2 rear fan

[Poul Munch]

My E2 has a fan on the rear side. This fan sucks air into the cabinet. Is this correct?
I would suppose that it should draw air out of the cabinet, through the HEPA filter.
( I have problems with warping large PETG prints)

The HEPA filter fan should be pulling air out of the machine and this is indicated by the sticker on the fan. Can you let me know if you can see the sticker from the back of the printer?

[Poul Munch]

Yes i can see the sticker.

Thank you for the update. If you can see the sticker from the outside then the air should be being pulled out of the machine through the filter. Can I have you try putting a piece of paper in front of the fan and let me know if it pulls the paper or is pushing it out?

[Poul Munch]

It pulls the paper the paper on to the cabinet. Thats how and why i got suspiciously.

Thank you for the update. It does sound like the fan is spinning in reverse and there is a chance that the plug is backwards and so we are spinning in reverse and flipping this plug could fix the issue.

It is not possible to flip the plug. The plug is polarized to prevent wrong insertion. But it is easy to see that red wire on one side of the connection becomes black on the other side. The question is, is it the wire harnes of the machine or is it the wire on the fan, who is made wrong.
I know how to upload a picture, it would be clear to see.
Best regards Poul

Thank you for the update. on the Male connector for the fan itself, there should be some silver tabs that you can depress and pull out the wire from each side and swap them.

I am afraid of spoiling the plug, so i cut the wires and solder them together again. Problem solved.
