The F3E1 error code indicates an issue with the thermistor, the sensor that detects water temperature in your KitchenAid dishwasher. This can happen for two reasons:
- Open circuit: The control board isn’t receiving any temperature readings from the thermistor.
- Short circuit: The control board is receiving incorrect, high readings from the thermistor.
Here’s a step-by-step guide to troubleshooting the KitchenAid dishwasher F3E1 error code:
- Check the thermistor connection.
- Locate the thermistor connector on the dishwasher’s control board.
- Make sure the connector is securely plugged in and free of dirt or debris.
- Gently clean the connector with a dry cloth if needed.
- Inspect the thermistor wiring.
- Carefully examine the wires connecting the thermistor to the control board for any visible damage.
- Look for signs of fraying, loose connections, or cuts in the insulation.
- If you find any damage, replace the wiring harness with a new one.
- Test the thermistor resistance.
- This step requires a multimeter.
- With the dishwasher powered off and unplugged, use the multimeter to measure the thermistor’s resistance at room temperature (around 25 °C or 77 °F).
- Compare the reading to the specified range in the table below.
- If the value falls outside the range, the thermistor might need replacement.
| Electric Part Name | Temperature | Ohmic Value |
|---|---|---|
| NTC thermistor | 25°C (77°F) | 47.1 kΩ |
- Consider replacing the thermistor:
- If the connection and wiring seem okay, and you’re not comfortable testing resistance, you can replace the thermistor itself.
- Replacement thermistors are typically available from appliance parts retailers.
- Main circuit board replacement (last resort).
- If the error code persists after trying the above steps, the issue might lie with the main control board.
- Replacing the control board is a more complex repair and might be best left to a qualified appliance technician.
By following these steps, you can potentially resolve the F3E1 error code and get your KitchenAid dishwasher back to functioning properly.
