Fully open the water supply cut-off valve for the dishwasher. If the valve is already open, unplug the dishwasher and shut off the water supply, and then disconnect the fill line and examine the water inlet valve. If the inlet screen is clogged, replace the water valve-don't just clean the screen, because debris could enter the valve body, causing the valve to stay open, resulting in flooding. Check the wiring connections on the water inlet valve and secure any loose connections. If the water valve won't open when activated, replace it.
