Temperature sensor fault

Locate the thermistor sensor in the sump area near the wash pump
Disconnect and measure resistance: approximately 55,000 ohms at 77F (25C)
An open circuit or near-zero reading confirms sensor failure
Trace the sump harness for breaks where it runs past the heat of the wash pump
Pro Diagnostic Tip
F1E1 on a budget Amana ADB dishwasher is a temperature-sensor loss: with no trustworthy water-temperature reading the control plays it safe and simply runs the wash for its maximum duration, which is why the telltale is a normal cycle that now drags past three hours. Measure the sump thermistor near 55,000 ohms at room temperature; an open or near-zero reading condemns it. Because the sump is a wet, warm spot, check the connector for corrosion before deciding the sensor bead itself has failed.
