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
Check the wiring harness for breaks, especially near heat sources in the sump
Pro Diagnostic Tip
On Amana ADB dishwashers, the thermistor is the same part used across the Whirlpool platform. A failed sensor causes extended cycle times because the board cannot verify water temperature — it defaults to maximum wash duration as a safety measure.
