Dishwasher keeps filling with water and draining again?

fdf784 Hotpoint Aquarius dishwasher keeps filling in the bottom and then draining again. I switched the machine off but it still filled. When I switched it on again, it drained. Is it a problem with the shut off valve to the water? I've posted this twice because of my typo errors in the first question. Plus, there was a typo error in the first question changing it to a swear word. I never swear so am really embarrassed. Sorry everyone! Serves me right for not checking it.
