While doing the weeks laundry yesterday in the A407 I noticed the softener cup in the agitator was getting its usual buildup of slime that didnt spin out fully so I popped it out to clean it, as well as the lint screen I take a soft brass wire brush to clean. I saw some black mold down inside that was covered by the cup and went to work. When I flipped the screen upside down it was really coated on the bottom of the inside top with black mildew as well. Gave it all a real good cleaning. Not sure what made me grab a flash light and peep down the center of the agitator but where the softener drains out through through the spokes and out the side was almost blocked solid with thick, black, caked up scunge from the last 38 years! Luckily I had just done a hot load of whites and was able to force the agitator off, havent been able to for months as I assumed the shaft got too rusty since last time I cleaned it a few years ago. After spending a good 30 mins blasting about 20lbs of nasty off it in the shower with my hand held adjustable nozzle and cleaners it was finally cleaned. Next I worked on the very rusty splines of the trans, sanded as best I could, then applied a light coat of dielectric compound to the splines above the ring seal after I filled the tub with some warm water and wire brushed all exposed metal parts, and also a fine scotch bright to clean the scuzz the agitator covered on the tub bottom, then reinstalled the agitator. I noticed the shaft has some play in the top bushing on the trans. I cant swap that 806 trans into this thing fast enough. I still cant figure out how the mildew gets there. Each time the machine gets used I leave the lid open to let air get in and dry things out.
