I listed model number that is stamped on the tag just inside the lid but have had no hits when searching for my model number (like it doesn't exist). All white, top loading, 1 black knob on the left of the console (white,colors,bright colors, etc), covered bleach port (not used), and coin-op.The top of the case (lid and console) tilt up, i would guess for maintanence.

Was a hand me down from a laundry, marked that its from 1980.

It leaked on the floor when filling up so I figured out how to open the case. The leak seems to be coming from the inlet hose.It's leaking in between the 1st and 2nd part of the hose at a 1.5" plastic cylindracal piece with slots in it (What is this?). Also, the 2nd part that connects into the tub looks corroded so I should probably replace that.I'm not sure how to get that hose unhooked from the tub. There seems to be a small black plastic ring holding the hose in place from the inside of the tub.

And any ideas on whats up with my model number?
Sorry for the long post and thanks in advance!

Edit: OK apparently through browsing my washer looks identical to either an A21CA, A21CM, or A21CT. From looking at the diagrams these are the part numbers I need (but what are they?):
2-6154, 2-15120
2-13013
2-13057

Model A21CM

Thanks so much, Gene.

Just out of curiousity...

Why is my washer marked as A21CS instead of -A,-M,or -T. Or maybe this is common?

Also, what is the purpose of the plastic sleeve between the hoses?
