Whirlpool Washer Error Code F25
Drive motor tachometer error
Drive motor tachometer error – the control is unable to properly detect motor speed; machine shuts down. If failure occurs during high-speed spin, door unlocks after 3 minutes.

What F25 means on a Whirlpool washer
The F25 error code on a Whirlpool washer indicates a drive motor tachometer error. The tachometer is a sensor integrated with the drive motor that generates a signal corresponding to the motor's rotational speed. The main control board monitors this signal continuously during operation to regulate spin speed and wash action. When the control cannot detect a valid tachometer signal, or receives a signal that falls outside expected parameters, it triggers the F25 code and shuts the machine down to prevent mechanical damage. If the failure occurs during a high-speed spin cycle, the door lock remains engaged for approximately 3 minutes before releasing, which is a safety measure to allow the drum to coast to a stop.
The most overlooked cause of this error on newly installed machines is an incomplete removal of the shipping hardware. Whirlpool front-load and certain top-load washers ship with bolts, foam blocks, or cable restraints that lock the drum and motor assembly in place during transit. If these are left installed, the motor will be loaded abnormally and the tachometer signal will be erratic or absent.
Beyond shipping hardware, the F25 code typically points to an issue in the motor speed sensing circuit. This includes a failed tachometer sensor or damaged wiring between the tachometer and the control board. A faulty drive motor itself can also produce this code if the internal tachometer winding has failed. In some cases, a defective main control board that cannot properly read or interpret the tachometer signal is the root cause, though this is less common and should be diagnosed only after ruling out wiring and motor issues.

Common causes of F25
- 01
Shipping hardware not removed
Wiring / connectionTransit bolts, foam spacers, or cable restraints left in place during installation prevent normal motor movement and cause erratic or absent tachometer readings. Check the back and interior of the machine for any remaining shipping components.
- 02
Loose or damaged tachometer wiring
Wiring / connectionThe wiring harness connecting the tachometer sensor to the control board can become loose, chafed, or broken, interrupting the speed signal. Inspect the connector at the motor and trace the harness for any visible damage or disconnection.
- 03
Faulty tachometer sensor
Part replacementThe tachometer sensor mounted on or integrated with the drive motor can fail, sending no signal or an incorrect signal to the control board. A failed sensor will require replacement of the sensor or the motor assembly depending on how it is serviced.
- 04
Failed drive motor
Part replacementIf the tachometer winding inside the motor itself has failed, the motor will need to be replaced. This is typically confirmed after ruling out wiring and connector issues.
- 05
Defective main control board
Part replacementIn rare cases, the control board loses the ability to read or process the tachometer input signal even when the motor and wiring are functioning correctly. This should be diagnosed last, after all other components have been tested.
