- 1). Test the electrical outlet that the 304 is plugged into with a device you know works. If the device does not power on, go to your breaker box and reset the tripped breaker by switching it to the "On" setting.
- 2). Run your fingers up and down the electrical cord coming out of the Fluval 304. Make sure there are no frays or breaks in the cord. If you find any breaks in the electrical cord, have the unit replaced.
- 3). Plug the 304 into the electrical outlet and turn it on via the "Power" button. Listen for the motor to start. If you hear the motor running, but the unit is not filtering, make sure there are no kinks in the output tube.
- 4). Straighten out the output tube and use your fingers to clear any clogs in it.
