I didn't put the top back on once I took everything apart! I did plug it in once i cleaned it to see where the noise was coming from- its the impeller/motor. I also made sure I had everything pushed in correctly & its still making noise. I'll try again this evening.
Definitely call them. I will say mine makes noise sometimes after a water change. I unplug it and quickly plug it back in. No issues.
