Error Code: F50 Difficulty: Hard
Problem: Indicates a motor fault, where the control system receives irregular feedback from the drive motor or tachogenerator (speed sensor).
How to Fix F50 Error (Step-by-Step)
- Ensure safety by unplugging the washer from the electrical outlet and shutting off both hot and cold water supply valves.
- To access the motor, you will need to remove the rear panel of the washing machine by unscrewing the retaining screws.
- Locate the drive motor, which is situated at the bottom of the drum. You will need to carefully remove the drive belt from the motor and drum pulleys.
- Disconnect the electrical wiring harness connected to the motor. Then, unbolt the motor from the washing machine’s tub assembly and carefully remove it.
- On the motor body, locate the two carbon brush holders. Unclip or unscrew the old brushes, paying attention to their orientation. Slide the new carbon brushes (Part No. 00154740) into the holders, ensuring they make good contact with the motor’s commutator.
- Carefully place the motor back into its mounting position and secure it with the bolts. Reconnect the electrical wiring harness and loop the drive belt back over the motor pulley and the large drum pulley.
- Reattach the rear access panel and secure it with its screws. Restore the water and power connections, then run a test cycle to confirm the motor is operating correctly.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
