The F3 E2 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 wiring fault or a failed sensor, and it’s often fixable at home with basic tools.
| Error code | E2 |
|---|---|
| Meaning | Water temperature sensor (thermistor) circuit is open, shorted, or reading out of range |
| Severity | Medium — the washer will usually stop mid-cycle and won’t finish washing |
| Time to fix | 20–45 minutes |
| Tools needed | Multimeter, screwdriver (Phillips or Torx depending on model) |
What the F3 E2 error means
On Maytag washers, error codes are shown as a paired code — F3 identifies the fault category (sensor problems) and E2 narrows it down to the water temperature sensor circuit specifically. This sensor sits on or near the tub and tells the control board how hot or cold the incoming water is, so the machine can pick the right wash temperature. When the board can’t get a valid signal from it, it throws F3 E2 and often pauses or cancels the cycle to avoid running with the wrong water temperature.
This is a different fault from the Maytag Washer F3 Error Code: Causes and Fixes alone, which can also cover other sensor issues, so it’s worth checking both if you’re troubleshooting.
Common causes
- Faulty or failed water temperature sensor (thermistor)
- Loose, corroded, or disconnected wiring harness at the sensor connector
- Damaged wire or pinched cable between the sensor and control board
- Sensor connector affected by water ingress or rust
- Control board fault misreading a healthy sensor signal
- Buildup of limescale or debris affecting the sensor’s contact with water
How to fix the F3 E2 error
- Power cycle the washer — Unplug the machine for 60 seconds, or switch off the breaker, then restart it. This clears minor control board glitches that can trigger a false E2 reading.
- Check the wiring harness — Unplug the washer, remove the rear or top panel, and locate the temperature sensor connector. Look for loose pins, corrosion, or a partially disconnected plug, and reseat it firmly.
- Test the sensor with a multimeter — Disconnect the sensor and measure its resistance. Compare the reading to your model’s service chart (resistance should change with water temperature); a fixed or infinite reading means the sensor has failed.
- Inspect the wiring for damage — Trace the cable from the sensor to the control board, checking for cuts, pinches, or chafing against the frame that could cause a short or open circuit.
- Replace the temperature sensor — If the sensor fails the resistance test, order the correct part for your model number and swap it out; this is the most common fix for a persistent E2 code.
- Call a technician if the error persists — If the sensor and wiring both test fine, the control board itself may be misreading the signal, which needs a professional diagnosis.
FAQ
Can I keep using my washer with an F3 E2 error?
It’s best not to. The machine may run without proper temperature control, which can affect wash results and, in some cases, cause the cycle to stop partway through.
Is the F3 E2 code the same as F3 E1?
No. F3 E1 usually points to a different sensor fault, similar to issues covered in the Maytag Washer F1 Error Code: Causes and Fixes guide, while F3 E2 is specific to the water temperature sensor circuit.
Do I need a technician to fix this?
Not always. Many owners resolve F3 E2 by reseating the wiring or replacing the sensor themselves. If you’re not comfortable using a multimeter or accessing internal panels, a technician visit is the safer option.
