It cannot be fixed, replacing the motor is the only option. In general I would assume for this to happen the pump has to be a very early one from 2006-2007 as we changed the metal in July 2007 and I have never heard of this happening to those made since. The preferred repair in my opinion is to send in the pump and we will discount a complete new one as so much has changed from 2007 to now, really none of the parts are identical in material and construction.
