I took the inlet valve apart, found it was clogged with sediment, so I cleaned it and reinstalled it. Water was still not filing, so I figured the valve was sticking. I ordered a new valve,because $30 was a lot cheaper than a new dishwasher. I took out the old valve with two screws, and disconnected the supply line, the brass elbow, one hose, and a wiring harness. I reattached it in the same place, re-using the all the other parts, and once I turned the power and water back on, it worked as before. The inlet valve was an exact match to my bad part, so it was an easy job.
