Horrible squealing noise

I was woken up this morning from a loud squealing noise coming from one of my 6000s driver boxes. There doesn't seem to be anything wrong with the stream itself as far as I can tell. Anyone have any suggestions on how to test or fix it?
 
Follow the directions in the manual for cleaning the drive unit. The alarm is a safety for preventing damage to a dirty pump.
 
Thanks Rvitko. There was a snail that crawled into it and was blocking the prop. Just looking at it from the outside you couldn't see it. Everything seems to be working fine. Next time I'll RTFM before freaking out. :)
