What F3-E1 means on your Jenn-Air dishwasher
Jenn-Air built its dishwasher diagnostics to name faults precisely, and F3-E1 corresponds to a specific breakdown in the system. The Jenn-Air F3-E1 error means water Temp Sensor Fail — The F3-E1 error code on Jenn-Air dishwashers indicates the water temperature sensor (thermistor) has failed, described in the control board’s own diagnostic language.
Most commonly, the trigger behind it is the NTC thermistor in the sump has drifted out of calibration or has an open circuit. The dishwasher cannot measure water temperature, affecting wash and sanitize cycle performance, which is worth knowing before you start troubleshooting.
Rather than leaving you to troubleshoot F3-E1 from scratch, the dishwasher narrows the problem down to a specific circuit or component before you even open a panel. It also helps to note whether the code appeared after a power outage, a recent cycle change, or routine use with no obvious trigger. A short video or photo of the display showing the exact code, taken with a phone, can also help a technician prepare before arriving. It’s also reasonable to check the appliance’s manual or rating plate for the exact model number before calling for service, since parts and control boards vary between production runs. Because the control board coordinates several subsystems at once, a fault in one area can sometimes produce misleading secondary symptoms elsewhere in the appliance.

Symptoms
- The display shows the f3-e1 code (water temp sensor fail)
- the tub fails to drain, or drains at the wrong point in the cycle
- water fills slower than usual, or not at all, before the fault appears
- the cycle indicator lights flash or cycle repeatedly without progressing
- the dishwasher shuts off abruptly mid-wash with no warning beeps
Common causes
- Failed thermistor sensor — The NTC thermistor in the sump has drifted out of calibration or has an open circuit.
- Damaged sensor wiring — The wire connecting the sensor to the control board has a break or poor connection.
Troubleshooting steps you can try
Run through these before assuming a component behind F3-E1 has failed outright:
- Run a hot water check. Before starting the dishwasher, run the kitchen faucet until the water is hot, then start a cycle. If dishes clean well with pre-heated water, the heating element works but the sensor is faulty.
- Power cycle. Turn off the breaker for 5 minutes and run a normal cycle. A temporary sensor glitch may clear with a reset.
When to call a technician
For the F3-E1 code, hand things off to a technician if:
- Sensor resistance is out of specification
- Wiring to sensor shows damage
- Sensor connector is corroded
On the question of resetting the F3-E1 code: A reset clears the error. If the sensor is permanently faulty, the code will return. If F3-E1 keeps returning after these steps, it’s a strong signal that a component inside the dishwasher has actually failed rather than glitched.
During the appointment, expect the technician to verify F3-E1 on your dishwasher electrically rather than by guesswork, which is what keeps the repair limited to the actual failed part instead of a wholesale parts swap.
If F3-E1 isn’t clearing on its own, schedule a visit with our team, or look up other codes in the error code library. You can cross-check model details on Jenn-Air’s website.
