Quick answer: Kenmore washing machine error code F25: motor speed sensor error. The most common cause is loose wiring between the drive motor, motor control unit, and main control. Try this first — power-reset the washer. If that does not clear it, check for shipping bolts.

What causes the F25 error?

  • Loose wiring between the drive motor, motor control unit, and main control
  • Failed drive motor tachometer
  • Failed motor control unit (MCU)
  • Failed drive motor
  • Shipping bolts or packing spacers still installed on a new washer

How to fix Kenmore F25 — 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 to 20 minutes, then plug it back in and press Stop twice. Start a short cycle to see if the code returns.
  2. Check for shipping bolts
    If the washer is new, make sure all shipping bolts, spacers, and packing materials were removed from the back. Leftover bolts stop the drum from moving and trigger this code.
  3. Reseat the motor wiring
    Unplug the washer and remove the back or bottom panel to reach the drive motor and motor control unit. Push every connector firmly back on. Restore power and test.
    Safety warning: Unplug the washer before touching any motor wiring.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • F25 returns after reseating the wiring
  • The tachometer reading is far from about 115 ohms
  • The MCU or drive motor needs replacement
  • The code appears immediately at power-on

Frequently asked questions

What is a tachometer on a washer?

It is a small sensor on the drive motor that tells the control board how fast the motor is spinning. Without that signal, the washer cannot control the spin and shuts down.

Why does F25 happen during high-speed spin?

That is when the motor works hardest and vibration is strongest. A slightly loose connector or a weak sensor often fails exactly at that moment.

Can I test the tachometer myself?

A technician checks it with a multimeter; it should read around 115 ohms. If the reading is far off, the motor or sensor needs replacement.
