It has made a funny sound right out of the box.

I don't appreciate loud sounds in the morning.

The old Keurig I had made a very loud pump sound when pumping water

Received my new Keurig k575 today but it's missing the gray piece that Clips in on top of the water filter handle that says replace or install on it, the machine is also pumping real slow n doesn't fill up the cup all the way..
