Washer shows F25 and may not spin properly, sometimes with unbalanced loads

Safety first: Unplug the washer before accessing the motor or underside.

Step-by-step checks:

• 1. Check drum and suspension: Spin the drum by hand to ensure it moves freely and the suspension is intact. Mechanical binding can cause tach errors.
• 2. Access motor: Remove the rear or bottom panel to reach the drive motor.
• 3. Inspect motor plug: Verify the motor connector is fully seated and free of corrosion or burn marks. Reseat it firmly.
• 4. Test tach coil: With the motor unplugged, measure resistance across the tachometer pins (refer to wiring diagram). An open or shorted reading indicates a bad motor assembly.
• 5. Inspect harness: Follow the harness from the motor to the control, checking for chafing or broken wires.

When to call a technician: If the motor and wiring appear good, the motor drive circuit on the control board may be faulty and should be tested by a professional.
