You might have some vapor lock. Try tilting it on its side while it's running. If you see bubbles coming out of the spray bar, and you start to hear more of a swishy rssssssh noise, you just have a big bubble in there. Once you get it going, slowly tilt it back up until it still runs even when upright. Then wait until you don't hear the noise any more, then try tilting it slightly right or left (but not all the way). When you're done it should be silent and water should be rushing out of the spray bar.
You can also check to see if this is the problem by tilting it all the way on its side then tilting it even a little more, so the motor part is lower than the green canister part. If you see a big old bubble coming up the clear green plastic part on the inside, then you know you need to burp your filter.
