If you own a Whirlpool washer, you know these machines are usually reliable. But like any appliance, they can run into problems. One of the most confusing issues users encounter is the F25 error code. At first glance, it looks like a random string of numbers and letters, but in reality, it’s the washer’s way of telling you something is wrong.
This article explains what the F25 code means, why it shows up, and how you can try to fix it at home. We’ll also cover when it’s best to stop troubleshooting and contact a professional.
What Does the Whirlpool Washer F25 Error Code Mean?
The F25 error code typically points to a drive motor tachometer error. The washer relies on its motor and a tachometer (a sensor that monitors motor speed) to control the spinning and washing cycles. If the sensor cannot read motor speed properly, the machine cannot function correctly, and the error is triggered.
In simple terms, the washer is unable to “sense” how fast the drum is turning, which disrupts the entire wash cycle.
Common Causes of the F25 Error Code

Several issues can trigger this code, ranging from small connection glitches to more serious mechanical problems. Below are the most common causes:
- Loose or damaged wiring – Worn-out or disconnected wires between the motor, tachometer, and control board can disrupt signals.
- Faulty drive motor – If the motor itself is damaged or has worn-out components, the washer cannot spin properly.
- Defective tachometer – When the sensor that tracks motor speed malfunctions, the system cannot register correct drum rotations.
- Control board failure (CCU or MCU) – The washer’s “brain” may not be processing signals correctly, leading to false or persistent error codes.
- Overloaded washer – Too many clothes inside can strain the motor and confuse the tachometer readings.
- Intermittent power supply – A sudden voltage drop or unstable power source may cause the system to misread motor activity.
Step-by-Step Troubleshooting Guide
Before you call for professional service, you can try some basic troubleshooting steps.
1. Reset the Washer
- Unplug the machine from the power source for at least 10 minutes.
- Plug it back in and run a short cycle.
- Sometimes, this clears temporary glitches.
2. Check the Load
- Remove excess laundry if the washer is overfilled.
- Try running a smaller load to see if the error clears.
3. Inspect Wiring Connections
- Disconnect the washer from power.
- Check the wiring harnesses between the motor, tachometer, and control board.
- Look for loose plugs, broken wires, or signs of burning.
4. Examine the Drive Motor
- If you’re comfortable handling tools, test the motor with a multimeter.
- Look for irregular resistance values that indicate a failing motor.
5. Test or Replace the Tachometer
- The tachometer is usually attached to the motor.
- If it cannot provide accurate readings, it will need replacement.
6. Consider the Control Board
- If all other components are fine, the Central Control Unit (CCU) or Motor Control Unit (MCU) may be defective.
- Unfortunately, diagnosing this requires technical expertise.
When to Call a Professional
While some DIY fixes can resolve minor wiring or loading issues, more complex problems involving the motor, tachometer, or control board are best left to trained technicians. Attempting these repairs without experience can lead to further damage or even safety risks.
