These impellers are perfectly machined to spin balanced and true. They spin by a magnetic field created by the motor. If they have been subjected to harsh water chemistry, low pH, tablet sanitizers etc, they can erode enough to become unbalanced. The indicator of an unbalanced impeller is a rattling noise from the pump which often results in reduced water flow through the heater, tripping the heater’s high limit.
