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.

First step from the service manual

Verify that the shipping system (bolts, spacers, cables) are removed.

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

  1. 01

    Shipping hardware not removed

    Wiring / connection

    Transit 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.

  2. 02

    Loose or damaged tachometer wiring

    Wiring / connection

    The 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.

  3. 03

    Faulty tachometer sensor

    Part replacement

    The 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.

  4. 04

    Failed drive motor

    Part replacement

    If 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.

  5. 05

    Defective main control board

    Part replacement

    In 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.

Frequently asked questions about F25

What does F25 mean on a Whirlpool washer?
The F25 code means the control board cannot properly detect the drive motor's speed through the tachometer signal. When this happens, the washer shuts down to prevent damage. If the error occurs during high-speed spin, the door will remain locked for about 3 minutes before releasing as a safety precaution.
How do I fix the F25 error on my Whirlpool washer?
Start by confirming that all shipping bolts, spacers, and cable restraints have been fully removed from the machine, as this is the most common cause on recently installed units. If the shipping hardware is already out, inspect the wiring harness and connectors at the drive motor for looseness or damage. If the wiring checks out, the tachometer sensor or the motor itself may need to be tested and possibly replaced.
Is it safe to use my Whirlpool washer when the F25 code is showing?
No, you should not continue running the washer while F25 is active. The machine shuts itself down because it cannot control motor speed safely, and forcing operation could cause further mechanical damage. Wait for the door to unlock, which takes up to 3 minutes after a high-speed spin error, and then address the underlying cause before running another cycle.
Will resetting my Whirlpool washer clear the F25 error?
A reset may temporarily clear the error code, but if the underlying problem with the tachometer signal is still present, the code will return as soon as the machine attempts to run. Resetting without diagnosing and fixing the root cause will not resolve the issue. Address the motor, wiring, or shipping hardware before relying on a reset.
How much does it cost to repair a Whirlpool washer F25 error?
If the fix is simply removing shipping hardware, there is no parts cost involved. Wiring repairs are generally low cost, typically in the range of $50 to $150 for a service call if a technician reseats or repairs a connector. Replacing a drive motor or tachometer sensor can range from $150 to $400 or more depending on labor rates and part pricing in your area. A main control board replacement tends to fall at the higher end of repair costs.
