I just received my Nano, and have done 1 24 hour cook. Boy did it work great! However, on my second cook, it started making LOUD humming and grinding noises. I have reviewed other posts in this forum, and this seems like a common problem.
I have removed the black cap at the bottom, and there were no obstructions. I also power cycled the Nano. The noises persist.
Odd humming noise:
The humming is kinda hard to hear over my voice...but it is VERY LOUD at times.
Any thoughts would be appreciated.
