my dishwasher will fill up with hot water, then instead of moving to
a wash cycle, it drains the water back out. the motor keeps running.
it's not going thru the wash or rince cycles. It does not matter which cycle i start with i tried pot&pans , just rinse , or normal wash. none of
these cycles work. it just fills then empties....any suggestions??

I disconnected the hose & ran the dishwasher. It fills up & washes the 1st cycle, pumps the water out, then stops for about 1 minute. Then the motor runs continuously, no water in or out.
