Dishwasher will not go thru wash cycles. I have full power going to dishwasher. When I turn

Question

I have full power going to dishwasher.  When I turn it on it fills with
water but it wont run thru the cycles even though I can hear the timer
going through its cycles. Once the timer has finished it will not
drain. Any suggestions will be greatly appreciatedHotpoint HDA2000 has worked before. It now fills with water but nothing else happens. And I don't know what to do to drain the water.I have a kenmore built-in dishwasher. It fills with water and then it stops. It will not wash. It then will go thru the other cycles and then will say its clean. When I open the door it is still full of water.
