GE Model #: GFW450SPM1DG not completing cycle - help identify part and function, please?

I have a GE washer Model #: GFW450SPM1DG which is not completing the cycle. When it stops, the clothes are wet - clearly the spin/drain hasn't completed. On another thread, I read about a water sensor being the problem, but I have replaced that with no change. Further research found a thread that indicated a possible clogged port that connects the tub by a tube to the level sensor.

That was a few months ago. Today I tore into it again and found a white plastic part at the bottom of the tub, which connects by a tube to the level sensor. If I blow into the tube, I can actuate the level sensor, so I think I'm on the right track.

However, the part doesn't seem to do anything. It plugs into the bottom of the tub and is sealed there with an O-ring (and two screws). If I blow into the part that connects into the tub, it's like blowing into a capped pipe. Nothing happens. I can't get any air through it.

The plastic is somewhat translucent, and there's some discoloration. I'm wondering if this is a piston kind of thing that should be moving with the water pressure to activate the level sensor.

Can anyone tell me if I'm on the right track?

Can you please update your last thread:

Yes, you should be able to blow through your air chamber, aka air dome.
Ok, so this washer you no longer own?
