The F3E2 error on your Maytag Washer means the control board has detected a problem with the water temperature sensor (thermistor) circuit. This usually points to a faulty sensor, a bad wire connection, or a control board issue that needs to be checked before you run another cycle.

Error code F3E2
Meaning Water temperature sensor (thermistor) fault detected by the control board
Severity Medium — washer may still run but temperature control will be unreliable
Time to fix 20–45 minutes
Tools needed Multimeter, screwdriver

What the F3E2 error means

F3E2 is part of the F3 family of error codes on Maytag washers, all of which relate to sensor faults that affect water level or temperature readings. Specifically, E2 tells you the fault is with the temperature sensor rather than the water level sensor. When the control board can’t get a valid reading from this sensor, it will stop the cycle and flash this code to protect the machine and your laundry from wash water that’s too hot or too cold.

Common causes

  • Faulty water temperature sensor (thermistor) that has failed or drifted out of range
  • Loose or corroded wiring connector at the sensor or control board
  • Sensor harness damaged by heat, wear, or rodents
  • Water inlet valve issue causing inconsistent water temperature
  • Control board malfunction misreading a good sensor signal
  • Buildup of mineral deposits or debris affecting sensor accuracy

How to fix the F3E2 error

  1. Power cycle the washer: Unplug the machine for 60 seconds, then plug it back in. This clears minor control board glitches and may reset the error.
  2. Check the wiring connections: Unplug the washer, remove the rear or cabinet panel, and inspect the wire harness leading to the temperature sensor for looseness, corrosion, or damage.
  3. Test the sensor with a multimeter: Locate the temperature sensor (usually near the water inlet or tub) and check resistance readings against the manufacturer’s spec at room temperature. Replace if readings are off or erratic.
  4. Inspect the water inlet valve: Make sure hot and cold water lines are supplying water at the correct temperature and pressure, since valve faults can trigger a false sensor fault.
  5. Replace the faulty sensor: If the sensor tests bad, order the correct part number for your model and swap it in — this is the most common fix for F3E2.
  6. Call a technician if the error persists: If wiring and sensor both test fine, the control board itself may need diagnosis or replacement.

FAQ

Can I keep using my washer with an F3E2 error showing?
It’s best not to. The washer may not heat water correctly, which can affect wash quality and, in some cases, cause the machine to stop mid-cycle.

Is F3E2 the same as the F3 error code?
No. F3 is a general family code covering sensor faults, but F3E2 specifically points to the temperature sensor rather than a water level issue — for more on the broader F3 code, see our Maytag Washer F3 Error Code: Causes and Fixes guide.

Do I need a professional to fix this?
If you’re comfortable using a multimeter and accessing the back panel, many homeowners replace the sensor themselves. If the wiring and sensor both check out fine, a technician should look at the control board.
