How old is the heater? It is wise to replace your heaters atleast once per year. Even if they are in perfect shape.

If it was stuck to the side of the sump or aquarium, it is possible that is where the noise was coming from. I had the same issue and couldn't figure it out for weeks. I spend hours with my head in my sump trying to track down the knocking noise. I removed the suction cups and let the heater free float and the noise went away. Never made any sense. There wasn't enough water movement in the sump to say it was the heater banging against the acrylic sump (plus it was held tight with suction cups). It was a Aqueon heater though.
