Maytag Dishwasher Error Code 3-1 or F3E1

Encountering the Maytag Dishwasher Error Code 3-1 or F3E1 can be perplexing, but fear not—this code is indicative of a Thermistor/OWI Sensor failure. The Thermistor, a crucial component responsible for monitoring water temperature, and the Optical Water Indicator (OWI) Sensor, which gauges the cleanliness of the water, play pivotal roles in ensuring optimal dishwasher performance.

Understanding the Error:

When the dishwasher detects a malfunction in the Thermistor/OWI Sensor, it triggers the 3-1 or F3E1 error code. This signals a disruption in the communication between these components and the electronic control board.

Troubleshooting Steps:

1. Disconnect Power: Unplug the dishwasher to ensure your safety during the troubleshooting process.
2. Inspect Wiring: Carefully examine the wiring connecting the electronic control board to the Thermistor/OWI Sensor. Look for any visible signs of wear, damage, or disconnection.
3. Wire Harness Repair or Replacement: If you discover a broken wire harness, repair or replace it to restore the electrical connection. A damaged wire can disrupt communication between the components and the control board.
4. Thermistor/OWI Sensor Examination: Check the Thermistor/OWI Sensor for any signs of physical damage. If the components appear intact, proceed to the next step.
5. Thermistor/OWI Sensor Replacement: If the wiring is undamaged but the error persists, it’s advisable to replace the Thermistor/OWI Sensor. Over time, these components can wear out, leading to inaccurate readings and triggering the error code.
