Kenmore Dishwasher Error Codes

Kenmore Dishwasher Error Code 3-1 or F3E1

When your Kenmore dishwasher displays Error Code 3-1 or F3E1, it’s often indicating an issue with the thermistor, which is the water temperature sensor, or the OWI sensor, also known as the Optical Water Indicator, responsible for detecting the amount of debris in the water. While these error codes can be worrisome, they offer valuable insights into what might be causing your dishwasher’s problems.

Understanding the Issue

  • Thermistor (Water Temperature Sensor): The thermistor plays a crucial role in maintaining the correct water temperature during the wash cycle. If it malfunctions, your dishwasher may not be able to heat the water to the desired temperature, impacting its cleaning efficiency.
  • OWI Sensor (Optical Water Indicator): The OWI sensor is responsible for monitoring the clarity of the water. It helps the dishwasher determine whether the water is clean enough to continue washing the dishes. If it fails, the dishwasher may not be able to effectively gauge the water’s cleanliness.

Troubleshooting and Solutions

If you encounter Error Code 3-1 or F3E1 on your Kenmore dishwasher, here are the steps to resolve the issue:

  1. Safety First: Always unplug your dishwasher from the electrical supply to ensure safety during the troubleshooting and repair process.
  2. Check the Wiring: Examine the wiring connections between the electronic control board and the thermistor/OWI sensor. Look for any signs of damage, fraying, or disconnection.
  3. Repair or Replace the Wire Harness: If you find damaged or broken wiring, it’s essential to repair or replace the wire harness. Properly secured and functioning wiring is crucial for the sensors to communicate with the control board.
  4. Inspect the Thermistor/OWI Sensor: If the wiring appears undamaged, the next step is to assess the condition of the thermistor and OWI sensor themselves.
  5. Replace the Faulty Component: If either the thermistor or OWI sensor is malfunctioning, it’s advisable to replace the problematic component. These sensors are critical for the dishwasher’s performance and should be in optimal working condition.
