Fix the F3E2 Error Code on your KitchenAid Dishwasher (Fast!)

Here’s how to troubleshoot the F3E2 error code on your KitchenAid dishwasher:

1. Clean the OWI sensor.

  • Dirt, grime, or limescale buildup on the OWI sensor can disrupt its ability to function correctly. Locate the OWI sensor (usually in the dishwasher tub near the water inlet) and consult your dishwasher’s manual for specific cleaning instructions.

2. Prevent future buildup.

  • Regularly check and clean the OWI sensor as part of your dishwasher maintenance routine.
  • Additionally, some models may have a self-cleaning cycle. Refer to your manual to see if this is available and how to activate it.

3. Clear the error code.

  • Some dishwashers allow you to clear the error code after troubleshooting. Consult your service manual for specific instructions on how to clear the code for your model.

4. Check the OWI sensor connection.

  • Ensure the connection between the OWI sensor and the control board is secure, with no loose wires or damage. If you find any damaged wires, replace them with new ones, following the manufacturer’s instructions.

5. Replace the OWI sensor.

  • If cleaning the sensor, checking the connection, and clearing the error code don’t resolve the issue, the OWI sensor itself might be faulty. Consider replacing the sensor with a genuine KitchenAid replacement part.

6. Main board replacement (last resort).

  • If the F3E2 error persists even after replacing the OWI sensor, there might be a problem with the dishwasher’s main control board. Replacing the main board is a complex repair and may require a qualified appliance technician.

Remember:

  • Always consult your dishwasher’s manual for specific cleaning and troubleshooting instructions before attempting any repairs.
  • When replacing parts, ensure you use genuine KitchenAid replacements for optimal compatibility and performance.

By following these steps, you can effectively troubleshoot the F3E2 error code and get your KitchenAid dishwasher back in top working order.
