JennAir Dishwasher Error Code F1E2
Water temperature sensor (thermistor) shorted
Common Causes
- 1Thermistor internally shorted
- 2Wiring shorted to the sump metal
- 3Water intrusion in the connector
Step-by-Step Troubleshooting
- 1
Disconnect power, reach the thermistor in the JennAir sump, and unplug its leads for testing
- 2
Read the resistance — a shorted sensor sits near zero ohms instead of the expected tens of thousands at room temperature
- 3
Look for chafed insulation or bare wire pressed against the metal sump body creating the short
- 4
Check the connector shell for moisture or corrosion forming a low-resistance bridge between pins
Pro Diagnostic Tip
A shorted thermistor feeds the JennAir control a false-hot signal, so it skips the heating phase and dishes emerge greasy because the water never reached sanitizing temperature — the combined sensor module is a single replaceable part.
You Might Also Notice
- •Dishes come out greasy or filmy
- •Sanitize phase seems ineffective
- •Program finishes unusually fast
- •Water feels cold when the door is opened mid-cycle
