JennAir Dishwasher Error Code F1E1
Water temperature sensor (thermistor) open
Common Causes
- 1Thermistor failed open
- 2Sensor wiring broken
- 3Connector corroded in the sump
Step-by-Step Troubleshooting
- 1
Find the thermistor in the JennAir sump near the wash pump and disconnect its leads
- 2
Measure resistance across the sensor, expecting roughly fifty-five thousand ohms at room temperature for this negative-coefficient type
- 3
An open or infinite reading confirms a failed thermistor that must be renewed
- 4
Trace the sensor harness for a break, paying attention to where it routes past the hot sump housing
Pro Diagnostic Tip
JennAir often combines the thermistor with the optical water sensor in one sump module, so an open thermistor pushes the dishwasher into extended run times because it can no longer confirm water temperature — check the combined assembly rather than a standalone probe.
You Might Also Notice

- •Water temperature seems wrong
