My curious dishwasher - help!?!?

Question:I can't understand what the symbols mean on my Bendix DWN-28 dishwasher.They are as follows (with the numbers as they appear with on the dishwasher turn knob):

(1) A pot and a plate -- heavy load?

(2) three level plates stacked on one another --full load?

(3) a plate at 45 degree angle with steam rising off it --?

(P) a "P" with a looped arrow -- ?

(4) a wine glass --not sure why this one is so special

(5) 22' -- 22 minutes??

(6) A plate with water spraying onto it -- presumably the rinse

Can anyone decipher these hieroglyphics?

Answers:
Did it come with an owners manuel and call the store you bouhgt it from they should know these things, and who hooked it up? Otherwise play with it a little and findout.
