The F5E1 error on your Maytag Washer means the control board has detected a problem with the water temperature switch or thermistor circuit. This is often caused by a faulty sensor, a loose wire connection, or a control board fault, and can usually be checked without a technician.

Error code F5E1
Meaning Water temperature switch/thermistor circuit fault detected by the control board
Severity Medium — the washer may still run but temperature control will be unreliable until fixed
Time to fix 20–45 minutes
Tools needed Multimeter, screwdriver

What the F5E1 error means

The F5E1 code appears when the washer’s control board cannot get a valid reading from the water temperature sensor (thermistor). This sensor tells the machine how hot or cold the incoming or wash water is, so the control board can adjust cycles accordingly. When the signal is missing, out of range, or shorted, the board flags F5E1 and may pause or stop the cycle.

This error is similar in nature to other F-series faults such as those covered in the Maytag Washer F5 Error Code: Causes and Fixes guide, since both relate to sensor and switch circuits feeding data back to the control board.

Common causes

  • Faulty water temperature sensor or thermistor
  • Loose or corroded wiring connector at the sensor
  • Damaged wiring harness between the sensor and control board
  • Failed control board unable to read the sensor signal correctly
  • Sensor mounted incorrectly after a previous repair
  • Mineral buildup or moisture affecting the sensor connection

How to fix the F5E1 error

  1. Power cycle the washer: Unplug it for 60 seconds, then plug it back in to clear a temporary control board glitch.
  2. Inspect the wiring harness: Open the access panel and check the wires running to the temperature sensor for looseness, corrosion, or damage.
  3. Reseat the sensor connector: Unplug and firmly reconnect the connector at the temperature sensor to rule out a poor contact.
  4. Test the sensor with a multimeter: Check resistance against the manufacturer’s specification chart; replace the sensor if readings are out of range or unstable.
  5. Check the control board connections: Look for burnt pins, loose plugs, or visible damage where the sensor wiring connects to the board.
  6. Replace the control board if needed: If the sensor tests fine but the fault persists, the board itself may be faulty and require replacement.

FAQ

Can I still run a wash cycle with an F5E1 error showing?
A. Sometimes, but the washer may not heat water correctly, so it’s best to fix the fault first to avoid poor wash results or repeated stops.

Is F5E1 the same as other F5 codes on Maytag washers?
A. No, it’s a sub-code specific to the temperature sensor circuit; other F5 variants can relate to different switches, as explained in the Maytag Washer F5 Error Code: Causes and Fixes guide.

Do I need a professional to fix this error?
A. Not always — checking and reseating wiring or testing the sensor with a multimeter is a DIY-friendly first step before assuming the control board has failed.
