Yep,I've had it off and on,drained and refilled and checked everything a few times already yet it is still doing the same thing.I had to leave it be for a while as the noise and bubbling was getting to me as well as holding me up from doing other things I need to take care of today.I'll check back on it later.Hmm that's weird. Normally its something like the hose, or just some trapped air that will come out if you give the can a good rock back & forth or just unplug & plug it in a few times to get it out. I would say check that the seal on the lid is fully sealed but if it weren't I'm sure you'd know by water running down.
