6055 Pump Stopped Working

[crs751]

I have (4) Tunze 6055's in my 75G tank. I suspected one of them wasn't working and today when I was cleaning them I confirmed that to be true. Is it reasonable to assume that the impeller needs to be replaced or is there something else that could be causing the pump not to work?

How old are they? Typically if it is the impeller it won't be lifeless. Does the controller light up? I would try one of the other impellers.

The controller does light up. I'll put an impeller from one of the other pumps to see if it works. If it doesn't then I am looking at another pump?

They do have a 5 year warranty, if it is older than that you can buy just the motor block, it is about half the cost. Make sure the metal shaft the impeller spins on is fixed in the motor, this is critical, the drive unit will just stick to the side of the motor and do nothing if it is not isolated in the middle of the pump and able to spin freely in the shaft.

Thanks Roger. I believe I replaced a motor on one of the other pumps. I believe you take the controller apart to remove the old cable and install the cable from the new motor base. Please advise if my memory is correct. Thanks.

Yes. It is part 6055.110
