Hey zipdang, that's the same thing my mom's filter-flo does. I've been wondering what that issue is. she didn't change speeds during a cycle, it just started malfunctioning, so I don't think it's anything you did, but could be a inherent design flaw with that era machine
Her washer looks exactly like the one in the auction Dadoes posted there. The washer is an early eighties vintage. I think she got it in about 1985 or so. I like the slow, deep rotations the agitator makes. With those types of vanes on it, the washer produces excellent turnover. Mom always poured the detergent into the top of the filter, so when the water poured into it, the detergent would dissolve without leaving residue on the clothes.
I remember when I went to college, and used the maytags there, I couldn't figure out where to put the detergent, since there was no dispenser, and not filter on top to put it in!
