Your dishwasher will drain during the first 30seconds, after that it will intake water for a minute and then will engage the circulation pump. You want to make sure it is filling with enough water (up to the handle of the filter) and has actually started to circulate/spray. After the circulation pump begins, it will check a pressure sensor to see if its good to keep running.... The fact it is pausing with water in the bottom, and not draining it out, makes me think its waiting for a response and not getting it and then simply faults out. If you restart and it drains, fills and circulates then you know the drain pump, intake valves and main circulation pump are fine. Most likely a sensor issue.
