A METHOD OF PREVENTING CORROSION IN A PUMP MOTOR FOR A DISHWASHER, AND ASSOCIATED APPARATUS

摘要

A method of preventing galvanic corrosion in a pump motor for a dishwashing appliance is provided, wherein the dishwashing appliance includes a tub portion and a sump assembly disposed about a lower end of the tub portion for receiving a dishwashing fluid therein. Such a method comprises operably engaging a pump assembly in fluid communication with the sump assembly. The pump assembly has a pump motor with a non-submersed aluminum winding terminating in and secured to at least one non-aluminum metallic electrical connector about a non-submersed interface. A moisture-resistant coating material is applied about the non-submersed interface between the aluminum winding and the non-aluminum metallic electrical connector, so as to prevent moisture from encroaching into the interface and promoting galvanic corrosion between the dissimilar metals of the winding and the at least one electrical connector. An associated apparatus is also provided.
