We are sorry to hear that this has happened. Most likely you need to just take the pump apart to clean it. To do so, unplug it and remove it from the waterfall. Pressing your thumb into the bottom cover, pull simultaneously towards the front of the pump. This will pop a L-shaped cover off of the pump. On the front underneath this cover, is a tear drop shaped cover for lack of a better description. Popped this off as well, then pull out the propeller blades you find underneath. Clean them well, and using a q tip, swab out the inside of the motor. This typically should be performed every month or two, depending on the tank's inhabitants and décor. For more assistance, please give us a call at 1-800-526-0650. We will return to the office on December 27.
