GE Monogram Dishwasher does not finish / drain

We have a GE Monogram dishwasher that runs, but doesn’t actually complete its cycle.

The dishes are cleaned, but the dishwasher does not turn off and water is left standing in the bottom of the dishwasher.

The dishwasher display gives a message that the cycle has been interrupted and to close the door to continue, but it just stays in this loop.

Turning the dishwasher off manually causes the water to drain correctly, so it appears that part of the process is functioning.

I’ve tried various wash cycles, all with the same problem. Any ideas?
