Completely Corroded Drum Spider in a Frigidaire-built Front Loading Washer
The drum support spider in this Frigidaire washer had corroded so much that the hub and drive shaft actually broke off. Note the pitting in the metal. That's from galvanic corrosion. It weakened the spider structural strength so much that it failed during use.
Whence cometh galvanic corrosion? Not certain at this time but possibilities are: 1) dissimilar metals between the spider assembly and the drum setting up a galvanic reaction, 2) some combinations of detergents, fabric softeners, and water conditions may set up a galavanic "cell" inside the washer during use.
