My Whirlpool dishwasher is on the fritz! Help!? When I try washing my dishes I can hear the contraption...

When I try washing my dishes I can hear the contraption start but water doesn't come within. I opened it surrounded by the middle of the wash cyle and found the dishes be hot but not wet. There wasn't anything blocking the wet inlet. Any ideas? I'd similar to to try to fix it without calling a repair man.
Answers:    The most adjectives simple stupid cause is something lower than the float, like a plastic spoon. If the float is individual held in the up postion it think it is full of water and won't agree to any water contained by.
start by making sure there is marine at the connection to the dishwasher
if in that is you will need to tryout different electrical parts and see if they are working or not
depending on what you find is what you have to fix
or
call for a repairman
