Kitchenaid Dishwasher Error Code 3-1 or F3E1

Error code 3-1 or F3E1 on your KitchenAid dishwasher signals a Thermistor and Optical Water Indicator (OWI) sensor failure. The thermistor is responsible for measuring water temperature, while the OWI sensor detects the level of debris in the water. When these crucial components malfunction, it can impact the dishwasher’s performance.

1. Faulty Thermistor: The thermistor, also known as the water temperature sensor, may experience a malfunction, leading to inaccurate temperature readings.
2. OWI Sensor Issues: The Optical Water Indicator sensor, designed to assess water quality, may fail to function correctly.
3. Wiring Problems: The wiring connecting the electronic control board to the thermistor/OWI sensor may be damaged or broken.

Troubleshooting Steps:

1. Unplug the Dishwasher:
   • Disconnect the dishwasher from the power source to ensure safety during troubleshooting.
2. Inspect Wiring:
   • Examine the wiring between the electronic control board and the thermistor/OWI sensor.
   • If you find any broken or damaged wires, repair or replace the wire harness.
3. Check Thermistor/OWI Sensor:
   • Inspect the thermistor and OWI sensor for visible damage or signs of wear.
   • If the components appear compromised, replacement is recommended.
4. Verify Temperature Settings:
   • Ensure that the dishwasher’s temperature settings are appropriate.
   • Adjust settings if necessary and run a test cycle to monitor for any improvements.
5. Professional Assistance:
   • If the issue persists after the above steps, or if you are unsure about component replacement, it is advisable to seek professional assistance.
