Kenmore Elite Dishwasher runs for 2 minutes then shuts off.
The only cycle that "works" is the Time Saver. When you press the Time Saver button the machine sets itself for 2 minutes and then runs for 2 minutes and shuts down. While it is running for 2 minutes the only button that works is the cancel button.

could be wrong but i will check main motor for overheating that will cause system to shut down
