Kenmore Dishwasher Error Code 3-3 or F3E3

Error codes on your Kenmore dishwasher can be frustrating, but understanding them and knowing how to troubleshoot can save you time and money on repairs. In this guide, we’ll dive deeper into the Kenmore Dishwasher Error Code 3-3 or F3E3 and explore the steps to address it.

Understanding Error Code 3-3 or F3E3:

This error code typically points to two potential issues:

1. OWI Calibration Failure: The Optical Water Indicator (OWI) sensor failed to calibrate correctly. This sensor measures the level of soil in the water to determine how long the dishwasher cycle should run.
2. Drain Hose Check Valve Failure: The check valve in the drain hose failed, allowing dirty water to backflow into the dishwasher. This can result in poor cleaning and potential contamination of your dishes.

Troubleshooting Steps:

1. Check the Drain Hose:
   • First, disconnect the dishwasher drain hose connection from the air gap or the garbage disposal (if you have no air gap).
   • Pour water through the drain hose to see if water backs up into the dishwasher tub. If you notice backflow, it’s a clear indication of a failed check valve in the drain hose.
2. Replace the Drain Hose:
   • If water backs up into the dishwasher, it’s time to replace the portion of the drain hose that connects to the drain pump. This will resolve the check valve issue and prevent further backflow.
3. OWI Sensor Calibration:
   • If water doesn’t back up into the dishwasher through the drain hose, reconnect the hose.
   • Run the Service Diagnostics Test according to the instructions in the tech sheet. During this test, ensure that you see “low soil level” indicated. This signifies the proper calibration of the OWI sensor in the diagnostic mode.
4. OWI Sensor Maintenance:
   • If the OWI test shows “high soil level,” it indicates that the OWI sensor might be dirty or malfunctioning. In this case, unplug the dishwasher and clean the OWI sensor carefully.
   • Reassemble the dishwasher, plug it back in to restore electrical power, and run the diagnostic test cycle. This will allow the electronic control board to calibrate the OWI sensor correctly on the next cycle.
5. Run a Normal Wash Cycle:
   • After the calibration and sensor maintenance, run a normal wash cycle to see if the error code reappears.
6. Replace the Thermistor/OWI Sensor:
   • If you still encounter the error code after performing the above steps, it may be necessary to replace the thermistor/OWI sensor.

By following these troubleshooting steps, you can address Kenmore Dishwasher Error Code 3-3 or F3E3 and ensure your dishwasher is back to running smoothly and efficiently. If you’re unsure about any step or if the issue persists, consider seeking professional appliance repair assistance.
