From Tech Sheet W15388178, p.30:

1.Check inlet valve. Check for proper water pressure before the valve to get hotter water to the dishwasher from the start.

2.Disconnect the sensor and measure resistance at the sensor body. Expected: 10 kΩ to 12 kΩ at 77°F (25°C).

3.Check the sensor harness for opens and shorts. Back-probe the sensor pins at the control board connector; a reading outside 5 kΩ to 50 kΩ indicates a failed sensor.
