The F3E0 error on your Maytag Washer means the main control board has detected a problem with the water temperature sensor (thermistor) circuit. This usually stops the wash cycle partway through, and in most cases it can be fixed by checking the sensor wiring or replacing the part.

Error code F3E0
Meaning Water temperature sensor (thermistor) circuit fault detected by the control board
Severity Medium — washer may still run but temperature control and heating are affected
Time to fix 20–45 minutes
Tools needed Multimeter, screwdriver (Phillips and flathead)

What the F3E0 error means

Your Maytag washer relies on a thermistor to measure the water temperature during fill and wash cycles. When the control board can’t get a clear, consistent signal from this sensor, it triggers the F3E0 code and typically pauses or cancels the cycle. This is different from related codes such as the one covered in the Maytag Washer F1 Error Code: Causes and Fixes guide, which points to a main control board fault rather than a sensor issue.

The problem can stem from the sensor itself, its wiring, or a fault in the control board reading the signal. It’s rarely a sign of major damage, but it should be addressed before running more cycles, since inaccurate temperature readings can affect wash performance and fabric care.

Common causes

  • Faulty or failed water temperature sensor (thermistor)
  • Loose, corroded, or disconnected wiring connector at the sensor
  • Damaged wiring harness between the sensor and control board
  • Water leaking onto the sensor connector causing a short
  • Main control board failing to interpret the sensor signal correctly
  • A buildup of scale or debris affecting the sensor’s readings

How to fix the F3E0 error

  1. Power down and unplug the washer. Always disconnect power before opening any panels to avoid electric shock.
  2. Locate the temperature sensor. On most Maytag washer models, it’s mounted near the water inlet valve or on the tub, depending on your model.
  3. Check the wiring connector. Inspect for corrosion, moisture, or a loose fit, and reseat the connector firmly.
  4. Test the sensor with a multimeter. Compare the resistance reading against your model’s manual specifications; a reading far outside range means the sensor needs replacing.
  5. Inspect the wiring harness. Look for pinched, frayed, or damaged wires running to the control board and replace any faulty sections.
  6. Reset the washer and run a test cycle. Plug it back in, run a short cycle, and confirm the F3E0 code doesn’t reappear. If it does, the sensor or control board likely needs professional replacement.

FAQ

Can I still use my washer if it shows F3E0?
It’s best not to. The washer may run cycles with inaccurate water temperatures, which can affect cleaning results and, in some cases, cause the cycle to stop unexpectedly.

Is F3E0 the same as other F3 codes on Maytag washers?
No. F3E0 specifically points to the temperature sensor circuit, while other variations, like those explained in the Maytag Washer F3 Error Code: Causes and Fixes guide, can relate to different sensor or water level faults.

How much does it cost to fix an F3E0 error?
Replacing a thermistor sensor typically costs between $20 and $60 for the part. If the control board is at fault, expect a higher repair cost, often requiring a technician.
