Since appliance expertise is running rampant here, I thought I'd ask.
My wife directed my attention to a problem this morning. The thingy that sticks up in the middle of the washer (what is that called, anyway?) is misbehaving. It is made up of two parts, and the lower part turns and stops, like it normally should. The part on top of that is supposed to be turning with it in one direction by means of some internal ratchet, but is not. There is some grinding noise coming from it.
How does such a thing come apart? Can it be fixed, or do I need to replace some ridiculously large chunk of the washer?
