I removed the front panel.
Ok, I got really brave and removed the front panel of the Amanatag and am watching the guts as it agitates. First, there is a fine black powder all over the horizontal surfaces which used to be the belt. The belt is not slipping, so far as I can tell, but it is wearing rapidly. Secondly, I have identified the source of the squeak!
As the machine agitates, the transmission lurches a little bit with each stroke of the agitator. Specifically, the whole transmission case spins during the spin cycle, and the brake is slipping during agitation. As the tub lurches back and forth with each stroke of the agitator, the brake chirps and squeals. Because the outer tub is plastic (oh, what quality), I can see the inner tub lurching back and forth inside during agitation. The brake pad is a flat piece of material, that is bolted into place along the side of the transmission. To engage the brake, the bottom of the brake-race rases up to sandwich the brake pad between itself and the top brake-race. Imagine a pulley that gets narrower to grip a belt and wider to disengage, except in this case instead of a belt, there is the brake pad.
It looks like the brake is too weak to hold the drum still during agitation, resulting in an indexing tub, of sorts. With each movement of the tub, the brake squeaks. Why is this happening? Is the brake pad worn, is the brake mechanism broken, or weak, or has something else broken, resulting in so much force being applied somewhere that the tub is forced to try to spin during agitation?
I will borrow a video camera and take some video later this evening.
Curious, and pissed at Maytag fo building this POS!
