Quick answer: Kenmore washing machine error code F5: water temp sensor fault. The most common cause is failed water temperature sensor (NTC thermistor). Try this first — power-reset the washer. If that does not clear it, check the water supply setup. If the code persists, call a qualified technician.

What causes the F5 error?

  • Failed water temperature sensor (NTC thermistor)
  • Broken or loose wire to the sensor, sometimes where wires flex near the drum
  • Poor connection at the sensor, heater relay, or control board
  • Failed heating element circuit on models that have a heater

How to fix Kenmore F5 — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Power-reset the washer
    Unplug the washer for 10 minutes, then plug it back in and press Stop twice. Start a cycle and see if the code returns.
  2. Check the water supply setup
    This washer mixes hot and cold water to reach the target temperature, so both supply hoses must be connected and the taps fully open. Fix any supply issue and retest.
  3. Have the sensor circuit checked
    If the code returns, the temperature sensor or its wiring is the likely fault. A technician will inspect the sensor wiring for breaks, test the sensor, and replace it if it reads out of range.
    Safety warning: Do not open internal panels yourself unless the washer is unplugged.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • F5 returns after a reset with both water supplies on
  • The temperature sensor tests out of range
  • Sensor wiring is broken or damaged
  • The heating element circuit or relay needs repair

Frequently asked questions

What does F05 mean on a Kenmore washer?

It is a water temperature sensor error. During the heating step the sensor value went out of range, or the heater circuit failed.

My model has no heating element. Why F05?

Your washer takes in hot and cold water and mixes them to hit the target temperature, so it still uses a temperature sensor. A bad sensor or broken sensor wire triggers the same code.

Can a broken wire cause F05?

Yes. The sensor wires flex a lot near the drum and can break inside their insulation, often under a tie-wrap. A technician can find and repair the break.
