First, try some troubleshooting. Make sure the tank is filled with water as this filter does not like low water levels. Second, soak the impeller in white vinegar for about 15 minutes after removing any debris, hair-like strands and so forth. Third, clean out the motor itself where the impeller sits. If you have an air stone or bubbler, make sure it isn't near the filter. And if you have sand as your substrate, it may have been caught in the impeller. This can make it noisy and destroy the impeller.
