Error code F3E2
Appliance Dishwasher
Quick answer

F3E2 points at the thermistor or OWI sensor. KitchenAid's step is a 30-second power-off, then service if the code is back.

Model compatibility: KitchenAid 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

KitchenAid lists the thermistor or OWI sensor as the potential cause of F3E2.

Quick view

  • Listed cause: thermistor or OWI sensor
  • Step for owners: 30 seconds without power
  • Code returns: schedule service

About the sensor

The help page for F3E2 says only “Potential Cause: Thermistor or OWI Sensor.” A thermistor senses temperature and the control relies on its readings. “OWI” is KitchenAid’s own shorthand and is not spelled out.

What KitchenAid asks you to do

  1. Cut power to the dishwasher for 30 seconds. A plugged-in unit is unplugged; a hard-wired one is switched off at its breaker on the home panel.
  2. Turn power on again.
  3. Start the dishwasher once more.
  4. Book service if F3E2 is shown again.

F3E2 next to its neighbours

Code Listed meaning
F3E1 Open sensor circuit, from a connection, the sensor or the control input
F3E2 Thermistor or OWI sensor
F3E3 Calibration failure, either OWI failure or a drain hose check valve that does not seal

Of the three, F3E2 is the loosest: it points to the sensor and says nothing about the way it failed.

Common questions

Thermistor or OWI, which one?
They are listed together, and the display gives no way to separate them.

How long a cycle proves the reset worked?
KitchenAid names no test length; it only says to schedule service if the code returns.

Does the code halt the machine?
Cycle behaviour is not described in the source.

Where does the sensor sit?
KitchenAid does not say.
