Maytag Dishwasher Error Code 3-2 or F3E2

Encountering Error Code 3-2 or F3E2 on your Maytag dishwasher signals a shorted thermistor or Optical Water Indicator (OWI) sensor. This hiccup can disrupt the seamless functioning of your dishwasher. Fear not, as we guide you through a detailed examination and potential solutions.

Understanding the Error:

This error code surfaces when a disruption is detected in the communication between the electronic control board and the thermistor/OWI sensor. These components play a pivotal role in maintaining optimal temperature and water levels during the dishwasher’s operation.

Troubleshooting Steps:

1. Power Down the Dishwasher: To initiate the troubleshooting process, unplug the dishwasher to ensure complete electrical disconnection.
2. Inspect Wiring: Conduct a thorough examination of the wiring connecting the electronic control board and the thermistor/OWI sensor. Look for any visible signs of wear, fraying, or damage.
3. Address Wiring Issues: If damaged wiring is detected, prioritize repairing or replacing the wire harness. This step is crucial to reestablishing the proper connection between the control board and the sensor.
4. Check Thermistor/OWI Sensor: If the wiring appears intact, shift your focus to the thermistor/OWI sensor. Inspect the sensor for any visible damage.
5. Replace Faulty Components: Should the thermistor/OWI sensor show signs of malfunction or damage, the next step is to replace it. This ensures accurate temperature readings and proper water level control.

While these steps can often resolve the issue, the complexity of dishwasher components necessitates caution. If the error persists or if you are unsure about the diagnosis, it is advisable to seek the expertise of professional technicians.
