JennAir lists a thermistor or OWI sensor for F3E2. One power cycle, then service if it comes back.
Model compatibility: JennAir reuses codes across series and model years, so F3E2 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
JennAir lists a thermistor or OWI sensor as the potential cause of F3E2.
The cause on JennAir’s list
For F3E2 the potential cause is a Thermistor or OWI Sensor. JennAir leaves the abbreviation OWI unexplained, so it stays as written.
In general a thermistor is a part that senses temperature. That is only a textbook definition, not a JennAir claim about its position or function in your machine. The code is linked to sensors, which is the limit of what the source supports.
One action, one fallback
Reset the power: disconnect the dishwasher for 30 seconds, then reconnect. Plug-in models are unplugged and replugged; hard-wired ones have the breaker flipped off and on.
Should F3E2 return, schedule service.
The entry lists no cleaning, no water check and no change to cycle settings.
Why not go further
JennAir offers no owner check beyond the reset, and more resets simply put off the call. When you contact us, describe what the dishwasher was doing when the code first appeared, since the source does not cover that. The sensor harness and heating circuit are not for owners to open.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
