Hotend fan seems to work but fails diagnostic

I've just got my brand new Mini+ assembled, and I've triple checked all the wiring. The hotend fan seems to work just fine - as soon as I turn it on, the fan turns for a few moments, and when I run the diagnostic it runs again. However, the diagnostic wizard keeps indicating there's some issue with the fan. 

If the fan works, wiring seems ok, but the diagnostic fails, what can I do to debug the issue?

Fans faluty it's not giving data out through yellow wire so contact prusa support though live chat so they can send replacement parts 

Please help me out by downloading a model it's free and easy but really helps me out https://www.printables.com/@Hello_474427/models

RE:

On the controller board, unplug the fan connector and replace it.

Do this several times.

Do the diagnostic wizard test.

Still a problem, contact prusa.
