Maytag Dishwasher Error Code F3 E2 — Temperature Sensor Fault
What this means
The F3 E2 error code indicates the dishwasher's thermistor is providing an abnormal temperature reading — either open circuit, shorted, or outside the expected range. The dishwasher may not heat water properly, resulting in poor cleaning performance and dishes that are not properly sanitized.
Alternate codes: F3E2
Step-by-step fix
4 stepsReset the dishwasher
Turn off the circuit breaker for 1 minute, then restore power and start a cycle to see if the error was a one-time glitch.
Temperature spikes during initial water fill can sometimes trigger false sensor errors.
Locate and test the thermistor
The thermistor is typically located in the sump area of the dishwasher. Access it and test with a multimeter — at room temperature it should read approximately 50,000 ohms (50K).
Disconnect the sensor before testing to get an accurate reading.
Check wiring connections
Inspect the wire harness from the thermistor to the main control board. Look for breaks, corrosion, or loose connectors.
Moisture in the dishwasher environment can corrode wire connections over time.
Replace the thermistor
If the sensor reads out of range, replace it. The thermistor typically snaps into the sump housing.
This is an inexpensive part that is easy to replace.
When to call a professional
If the thermistor and wiring test good but the error persists, the main control board's sensor circuit may be faulty.
